Content and reactivity to product perfumes in fragrance mix positive and negative eczema patients. A study of perfumes used in toiletries and skin-care products.

The aim of the study was to investigate the elicitation potential of perfumes from 17 commonly sold lower-price cosmetic products. 8 of the perfumes were from stay-on cosmetics and 9 were from wash-off cosmetics. Each perfume was tested in 500 consecutive eczema patients, who also were tested with the European standard patch test series. 4.2% reacted to 1 or more of the wash-off product perfumes and 3.2% to 1 or more of the stay-on product perfumes. Concordant positive reactions between the fragrance mix and the product perfumes were found in 81.3% of positive reactions to the stay-on product perfumes and in 52.4% of the reactions to the wash-off product perfumes. Compared to the fragrance mix alone, only 1 additional case of contact allergy to the product perfumes was detected by balsam of Peru. Chemical analysis revealed that between 1 and 5 of the chemically-defined constituents of the fragrance mix were present in all of the product perfumes. Geraniol was found in 12 of the 17 perfumes and was most often detected. The concentration of the target fragrance materials ranged from 0.005%-1.35 w/v%. It is concluded that the allergenic constituents of the fragrance mix are impossible to avoid if perfumed cosmetics are used. Furthermore, patients suspected of perfume allergy need to be tested with their own perfumed products, as far from all cases of perfume allergy are detected by the fragrance mix and/or balsam of Peru in the European standard patch test series.

The effect of perfume "ageing" on the allergenicity of individual perfume ingredients.

An ingredient of a perfume which is a sensitizer may become hypoallergenic by interacting with other ingredients during the ageing process of the perfume. Thus, a patient with an exquisite allergic sensitivity to cinnamic aldehyde tolerates two perfumes containing cinnamic aldehyde without acquiring a dermatitis. There are several theories of why cinnamic aldehyde can become a non-sensitizer in a perfume mixture. Testing with a mature perfume may be much more significant than testing with individual ingredients.

Perfume sensitivity in adult females. A study of contact sensitivity to a perfume mix in two groups of student nurses.

The incidence of contact sensitivity to a perfume mix was investigated in two groups of student nurses by questionnaire and patch testing. Twenty-nine of ninety gave a history of dermatitis on exposure to fragrances or perfumed cosmetics. Fifteen of eighty-five showed a positive patch test reaction to a perfume mix comprising 2% concentrations of eight different perfume ingredients, and twelve of the fifteen had a positive history. Chi-square analysis of the data indicates that the results of the two methods of measurements are significantly related (p < 0.0001).

Odds and Trends: Recent Developments in the Chemistry of Odorants Note on trademarks: Words which we know or have reason to believe constitute registered trademarks (R) are designated as such. However, neither the presence nor absence of such designation should be regarded as affecting the legal status of any trademark. Note on perfume analysis: The quoted percentages of perfume raw materials in market products are rounded figures. They are often derived from area percentages from the GC (FID) analysis, and are thus subject to analytical error.

Fragrance chemistry is, together with the closely related area of flavor chemistry, one of the few domains, if not the only one, in which chemists can immediately experience structure-activity relationships. This review presents structure-odor correlations and olfactophore models for the main odor notes of perfumery: "fruity", "marine", "green", "floral", "spicy", "woody", "amber", and "musky". New trendsetters and so-called captive odorants of these notes are introduced, and recent activities and highlights in fragrance chemistry are summarized. The design of odorants, their chemical synthesis, and their use in modern perfumery is discussed. Our selection is guided and illustrated by creative fragrances, and features new odorants which encompassed current trends in perfumery. New odorants for grapefruit and blackcurrant, for galbanum, and leafy top notes are presented. Compounds with fashionable marine, ozonic, and aquatic facets are treated, as well as new odorants for classical lily-of-the-valley, rose, and jasmine accords. Compounds with sweet and spicy tonalities are also discussed, as are the most recent developments for woody notes such as sandalwood and vetiver. We conclude with musky and ambery odorants possessing uncommon or unusual structural features. Some odor trends and effects are illustrated by microencapsulated fragrance samples, and areas where there is need for the development of new synthetic materials and methodologies are pointed out. Thus, chemists are invited to explore fragrance chemistry and participate in the design and synthesis of new odorants. This review gives the latest state of the art of the subject.

Inhalation challenge effects of perfume scent strips in patients with asthma.

BACKGROUND: Perfume- and cologne-scented advertisement strips are widely used. There are, however, very few data on the adverse effects of perfume inhalation in asthmatic subjects. OBJECTIVES: This study was undertaken to determine whether perfume inhalation from magazine scent strips could exacerbate asthma. METHODS: Twenty-nine asthmatic adults and 13 normal subjects were included in the study. Histories were obtained and physical examinations performed. Asthma severity was determined by clinical criteria of the National Heart, Lung, and Blood Institute (NHLBI). Skin prick tests with common inhalant allergens and with the perfume under investigation were also performed. Four bronchial inhalation challenges were performed on each subject using commercial perfume scented strips, filter paper impregnated with perfume identical to that of the commercial strips, 70% isopropyl alcohol, and normal saline, respectively. Symptoms and signs were recorded before and after challenges. Pulmonary function studies were performed before and at 10, 20, and 30 minutes after challenges. RESULTS: Inhalational challenges using perfume produced significant declines in FEV1 in asthmatic patients when compared with control subjects. No significant change in FEV1 was noted after saline (placebo) challenge in asthmatic patients. The percent decline in FEV1 was significantly greater after challenge in severely asthmatic patients as compared with those with mild asthma. Chest tightness and wheezing occurred in 20.7% of asthmatic patients after perfume challenges. Asthmatic exacerbations after perfume challenge occurred in 36%, 17%, and 8% of patients with severe, moderate, and mild asthma, respectively. Patients with atopic asthma had greater decreases in FEV1 after perfume challenge when compared with patients with nonallergic asthma. CONCLUSIONS: Perfume-scented strips in magazines can cause exacerbations of symptoms and airway obstruction in asthmatic patients. Severe and atopic asthma increases risk of adverse respiratory reactions to perfumes.

The influence of shaving method on perfume allergy.

Among men, the most frequent contact allergens are perfumes (fragrance mix and balsam of Peru). Considering that the main cause of nickel allergy is ear-piercing, shaving with a razor blade might be the cause of perfume contact allergy, by creating small wounds that increase the penetration of applied perfume substances derived from soaps, shaving foams and after-shave lotions. 19 males with contact allergy to fragrance mix and/or to balsam of Peru were interviewed about their shaving habits by letter. 17 responded (89%), of whom 12 (71%) had been using razor blades continuously for a period of at least 1 year. At our clinic, the frequency of razor blade usage was found to be 45% in patch tested men without perfume contact allergy. When comparing the frequencies of razor blade usage among patch tested men with and without perfume contact allergy, there was a statistically significant over-representation (p = 0.047) among those with perfume allergy. The risk of perfume allergy when using razor blades was found to be 2.9 (odds ratio).

Effect of Types of Perfume Compounds on the Hydrophile-Lipophile Balance Temperature.

The effect of added perfume compounds (d-limonene (LN), alpha-hexylcinnamic aldehyde (HCA), beta-ionone (IN), benzyl acetate (BA), linalool (LL), geraniol (GL), eugenol (EL), and cis-3-hexenol (HL)) on the three-phase behavior was investigated in water/octaethylene glycol dodecyl ether (C(12)EO(8))/perfume compound systems. The HLB (hydrophile-lipophile balance) temperatures are considerably lower than those of saturated hydrocarbon systems and are in the order LN > HCA > IN > BA > LL > GL > EL > HL. It is considered that the perfume molecules tend to be solubilized in the vicinity of the interface of the water-hydrocarbon moieties of the surfactant or the surfactant palisade layer. To confirm this, the location of the solubilized perfume compound in aggregates of liquid crystals was investigated by small-angle X-ray scattering (SAXS). In the LN, HCA, IN, BA, LL, and GL systems, the hexagonal liquid crystalline phase changes to lamellar liquid crystals on addition of each perfume compound, whereas the hexagonal liquid crystalline phase is directly changed to a reverse micellar solution phase in the EL and HL systems. The effective cross-sectional area per surfactant molecule, a(s), was calculated by using interlayer spacing measured by SAXS. Perfume compounds, which reduce the HLB temperature greatly, tend to penetrate into the surfactant palisade layer and increase a(s). Thus, the perfume molecules change the surfactant curvature from positive to negative. The more the perfume compound penetrates into the palisade layer, the lower the HLB temperature becomes.

Phototoxic properties of perfumes containing bergamot oil on human skin: photoprotective effect of UVA and UVB sunscreens.

As part of an international cooperative study of the photophysical, photomutagenic and photocarcinogenic properties of bergamot oil and the effect of UVA and UVB sunscreens, the phototoxic properties of model perfumes containing 5, 15 and 50 ppm 5-methoxypsoralen (5-MOP) in bergamot oil with and without a sunscreen have been investigated on human skin. It has been confirmed that the photosensitivity of human skin is maximal 2 h after perfume application. Interestingly the addition of a UVA sunscreen is more efficient for decreasing the phototoxic properties of bergamot oil than is a UVB sunscreen. The addition of sunscreens in a model perfume containing 50 ppm 5-MOP in bergamot oil can reduce the phototoxic properties of this perfume to a toxicity equivalent to that produced by the application of a model perfume containing 15 ppm 5-MOP without sunscreens. However, despite their promising protective effect in vitro, UVB and UVA sunscreens at low concentration (0.5%-1%) in perfumes cannot suppress the phototoxicity of bergamot oil on human skin.

Placebo-controlled challenges with perfume in patients with asthma-like symptoms.

A group of nine patients with respiratory symptoms after nonspecific irritating stimuli, but without any IgE-mediated allergy or demonstrable bronchial obstruction, were referred to the asthma/allergy outpatient department for evaluation of suspected asthma. In order to find a provocation model and objectively assess these patients' symptoms in controlled studies, provocation with perfume or placebo was performed. The same patients were also subjected to perfume provocation with or without a carbon filter mask to ascertain whether breathing through a filter with active carbon could prevent the symptoms. The patients breathed through the mouth during the provocations, as they used a nasal clamp to prevent any smell of perfume. We found that the patients' earlier symptoms could be verified by perfume provocation. Breathing through the carbon filter had no protective effect. The conclusion is that symptoms suggesting hyperreactivity of the respiratory tract and asthma can be provoked by perfume without the presence of bronchial obstruction, and that using a carbon filter mask has no preventive effect. The symptoms are not transmitted via the olfactory nerve, since the patients could not smell the perfume, but they may have been induced by a trigeminal reflex via the respiratory tract or by the eyes.

Contact allergy to popular perfumes; assessed by patch test, use test and chemical analysis.

The frequency of contact allergy to the 10 best-selling women's perfumes was studied in 335 consecutive female eczema patients by patch testing. The diagnostic ability of the fragrance mix, in relation to these products, was evaluated. Of eczema patients, 6.9% had a positive patch test to one or more of the perfumes, and 56.5% of these had a concurrent positive reaction to the fragrance mix. Hence, testing with the patients' own cosmetics is a significant part of diagnosing perfume allergy. The clinical relevance of the patch-test reactions to the commercial perfumes was equal to that of the fragrance mix, as judged from the patient's history and use testing with one of the perfumes. At least three of the chemically defined sensitizers in the fragrance mix were detected in all the perfumes by gas chromatography-mass spectrometry, which indicates that the fragrance mix is a good imitation of actual exposure.

Occupational acute anaphylactic reaction to assault by perfume spray in the face.

BACKGROUND: Perfumes have been associated with rashes in employees exposed to scented soaps or with allergic conditions, such as rhinitis or asthma, in employees exposed to perfumes or fragrances in the air. METHODS: Reported here is a case of an anaphylactic reaction and respiratory distress as a result of a deliberate assault with a perfume spray. The medical literature was searched using the key words "fragrances," "respiratory distress," "assault," and "health care workers." RESULTS: A female medical assistant with no history of asthma or reactions to fragrances was assaulted by a patient, who pumped three sprays of a perfume into her face. The employee experienced an acute anaphylactic reaction with shortness of breath, a suffocating sensation, wheezes, and generalized urticaria, and required aggressive medical treatment, a long period of oral bronchodilator therapy, and, finally, weaning from the medications. CONCLUSIONS: Perfumes are complex mixtures of more than 4,000 vegetable and animal extracts and organic and nonorganic compounds. Fragrances have been found to cause exacerbations of symptoms and airway obstruction in asthmatic patients, including chest tightening and wheezing, and are a common cause of cosmetic allergic contact dermatitis. In many work settings the use of fragrances is limited. Assault is becoming more common among workers in the health care setting. Workers should be prepared to take immediate steps should an employee go into anaphylactic shock.

Temperature dependent primary irritant dermatitis from lemon perfume.

In a recent outbreak of hand eczema amongst cleaning personnel after the introduction of a new, lemon-scented detergent, it was noted that the patients complained of a burning, stinging sensation when their hands were submerged in hot detergent solutions. Since routine patch testing with the Standard Series and perfume components was of no help in pinpointing the responsible agent, testing with selected perfume components was repeated at higher temperatures. Identical tests were placed on both forearms for 20 min, one arm being exposed to 43 degrees C, the other to 23-25 degrees C. Little or no reaction was seen on the "cold" arm, whereas the lemon perfume component Citral proved to be a strong primary irritant at higher temperatures. Histological examination of the test sites showed the reaction to be of a toxic (primary irritant) nature. Surprisingly, the toxic character could still be recongized in biopsies taken as late as 48 h after exposure. It is suggested that: 1. Heat plays an important part in the outbreak of primary irritant (toxic) dermatitis and can be used as an accelerating factor when testing for primary irritants. 2. It is important to be sure that detergents and detergent perfumes do not contain substances which act as irritants at the temperatures at which they are habitually used (45-50 degrees C). 3. We probably ought to use lukewarm rather than hot water for manual dishwashing and cleaning whenever it is possible.

[Clinical forms of skin manifestations in allergy to perfume].

Perfumes are increasingly used in an ever wider variety of fields, including perfumes proper, cosmetic products, hygienic products, drugs, detergents and other household products, plastics, industrial greases, oils and solvents, foods, etc. Their composition is usually complex; it involves numerous natural and synthetic sweet-smelling constituents, more than 5,000 of which are known (13). Perfumes may produce toxic and, more often, allergic respiratory disorders (asthma), as well as neurological (10) and cutaneous disorders. They are the most common cause of skin allergy to cosmetic products (1, 11) and one of the most important causes of skin allergy to topical drugs or even to syrups which may reactivate contact dermatitis (24). People engaged in the manufacturing of these products may become sensitized to perfumes.

Ethyl alcohol (ethanol)-containing cologne, perfume, and after-shave ingestions in children.

Colognes, perfumes, and after-shaves containing ethyl alcohol (ethanol) are frequently ingested by children. These products may contain from 50% to 99% ethanol. To determine if ingestion of colognes, perfumes, or after-shaves by children results in serious ethanol toxic reactions, this retrospective study was performed. One hundred twenty-three cases of children younger than 6 years old who ingested these products were reviewed. The cases were arbitrarily divided into three groups based on the amount ingested by history. Group 1 included children in whom less than 30 mL was ingested; group 2, 30 to 60 mL was ingested; and group 3, more than 60 to 105 mL was ingested. Of the 102 patients in group 1, no children experienced symptoms or signs. One of 17 children in group 2 was described by parents as sleepy but was asymptomatic one hour later. Two of four children in group 3 behaved as if intoxicated, yet blood ethanol levels were undetectable within 2 1/2 hours after ingestion. Based on our study, asymptomatic children who ingested by history less than 105 mL of a cologne, perfume, or after-shave and remain asymptomatic can be safely watched at home. All children with symptoms of intoxication need health care facility referral.

Provocations with perfume in the eyes induce airway symptoms in patients with sensory hyperreactivity.

BACKGROUND: In earlier studies, we have shown that patients with a history of sensory hyperreactivity develop asthma-like symptoms when exposed to strong scents, even if they cannot smell any scent. METHODS: For study of possible pathophysiologic mechanisms behind sensory hyperreactivity, the patients' airways and eyes were separately exposed to a common inducing factor, perfume. Eleven patients with a history of hyperreactivity to chemical trigger factors, such as perfume, were provoked single-blindly in a placebo-controlled, randomized study. During airway exposure, the eyes were covered and, during the eye exposure, the patients inhaled fresh air. A special face mask or a nose clip was used to avoid any smell. RESULTS: During the 30-min exposure to perfume, there was a gradual increase in three main symptoms; i.e., eye irritation, cough, and dyspnea, after both the airway and eye exposures. The increases were significant compared with placebo. CONCLUSIONS: Asthma-like and other symptoms, such as irritation of the eyes, may be induced by exposure of both the airways and the eyes in patients with sensory hyperreactivity. This points to the importance of studying the sensory nervous system, not only in the airways, but also in other organs.

Identification of Lilial as a fragrance sensitizer in a perfume by bioassay-guided chemical fractionation and structure-activity relationships.

Fragrance materials are among the most common causes of allergic contact dermatitis. The aim of this study was to identify in a perfume fragrance allergens not included in the fragrance mix, by use of bioassay-guided chemical fractionation and chemical analysis/structure-activity relationships (SARs). The basis for the investigation was a 45-year-old woman allergic to her own perfume. She had a negative patch test to the fragrance mix and agreed to participate in the study. Chemical fractionation of the perfume concentrate was used for repeated patch testing and/or repeated open application test on the pre-sensitized patient. The chemical composition of the fractions giving a positive patch-test response and repeated open application test reactions was obtained by gas chromatography-mass spectrometry. From the compounds identified, those that contained a "structural alert" in their chemical structure, indicating an ability to modify skin proteins and thus behave as a skin sensitizer, were tested on the patient. The patient reacted positively to the synthetic fragrance p-t-butyl-alpha-methylhydrocinnamic aldehyde (Lilial), a widely used fragrance compound not present in the fragrance mix. The combination of bioassay-guided chemical fractionation and chemical analysis/structure-activity relationships seems to be a valuable tool for the investigation of contact allergy to fragrance materials.

Comparison of allergenicity of a perfume in animals (guinea pig maximization test) and in humans (usage test).

Using the Guinea Pig Maximization Test, the sensitization rate of a perfume was shown to be 10 per cent, which means a mild allergenicity rate. A usage sensitization trial was performed with the same perfume included in a soap, on 300 persons for 2-3 months. Seventy-five of these, all house-wives, were randomly selected and tested epicutaneously, after the trial. One woman reacted allergically towards the perfume. This means a sensitization rate of 1.3 per cent, which is a maximum value, as she could, theoretically, have been sensitized before.
