Self-reported illness from chemical odors in young adults without clinical syndromes or occupational exposures.

The present survey of young adult college students investigated the prevalence of self-reported illness from the smell of the five following common environmental chemicals (cacosmia): (1) pesticide, (2) automobile exhaust, (3) paint, (4) new carpet, and (5) perfume. Sixty-six percent of 643 students reported feeling ill from one or more of the five chemicals; 15% identified the smell of at least four chemicals as making them ill. Ratings of illness from pesticide correlated weakly but significantly with ratings for the largest number of individual symptoms (9 of 11); daytime tiredness and daytime grogginess both correlated at high levels of significance with illness ratings (on a 5-point scale) for four of the five chemicals. The most cacosmic group (CS) included significantly more women (79%) than the noncacosmic group (NS) (49%); women overall were more cacosmic than men (p < .001), even with the significant covariate of depression. Ratings of cacosmia correlated only weakly with scores for depression (r = 0.16), anxiety (r = 0.08), and trait shyness (r = 0.18) in the total sample. On stepwise multiple regression with cacosmia score as the dependent measure, shyness accounted for 5.8% of the variance, while depression, anxiety, sense of mastery, and repression did not enter the equation. Histories of physician-diagnosed hay fever, but not asthma, were more frequent in the CS (16%) than in the NS group (5%). Without the confounds of chronic illness or specific treatment programs, these data are similar to patterns described clinically for a subset of patients with multiple chemical sensitivities (MCS), including previous data on increased nasal resistance in MCS.(ABSTRACT TRUNCATED AT 250 WORDS)

Rating and recognition of peers' personal odors by 9-year-old children: an exploratory study.

Eighteen elementary school children assessed the pleasantness and perfumed aspect of familiar peers' odors, sampled through tee shirts worn without modification of hygienic habits. The participants were also requested to categorize the odors by sex and to recognize those of several target classmates varying in sex and socioemotional status (the participant's most preferred classmate vs. a mere acquaintance). The ratings of odors by familiar peers appeared consistent with those obtained from nonfamiliar peers and adults and varied according to the sex of wearer of the tee shirts. For the five categories of peers examined, as well as for the participants themselves, olfactory recognition was better than chance. Moreover, it was higher for the same-sex preferred peers than for the others only for the female perceivers. The results are discussed in terms of their behavioral relevance for peer relationships, focusing especially on (a) the relations between sex differences in odors and gender development and (b) the function of olfactory memory in the emotional regulation of friendships.

Pheromonal influences on sociosexual behavior in postmenopausal women.

To determine whether a putative human sex-attractant pheromone increases specific sociosexual behaviors of postmenopausal women, we tested a chemically synthesized formula derived from research with underarm secretions from heterosexually active, fertile women that was recently tested on young women. Participants (n = 44, mean age = 57 years) were postmenopausal women who volunteered for a double-blind placebo-controlled study designed, to test an odorless pheromone, added to your preferred fragrance, to learn if it might increase the romance in your life. During the experimental 6-week period, a significantly greater proportion of participants using the pheromone formula (40.9%) than placebo (13.6%) recorded an increase over their own weekly average baseline frequency of petting, kissing, and affection (p = .02). More pheromone (68.2%) than placebo (40.9%) users experienced an increase in at least one of the four intimate sociosexual behaviors (p = .04). Sexual motivation frequency, as expressed in masturbation, was not increased in pheromone users. These results suggest that the pheromone formulation worn with perfume for a period of 6 weeks has sex-attractant effects for postmenopausal women.

Musk xylene: analysis, occurrence, kinetics, and toxicology.

1,3-Dimethyl-2,4,6-trinitro-5-tert.-butylbenzene (musk xylene, MX), a synthetic musk, is often used in fragrances and soaps to substitute the natural musk. MX belongs to the common group of nitromusk compounds. The main environmental intake of MX occurs after sewage introduction. The consumption of fish and drinking water as well as the use of body care and perfumed household products could lead to an ingestion of this substance in humans. Although the acute oral and dermal toxicity of MX is low, some hint for the carcinogenic potential of MX was found in one animal experiment. These findings and the high potential of MX as environmental contaminant, it is stable against biological and chemical degradation and it is highly lipophil, raised considerable attention in the field of environmental medicine. Biological monitoring and the toxicology of MX, which previously has been described to occur in human milk, human fat tissue, as well as human blood samples, are of central interest. The aim of this article is to summarize the data on the analysis, occurrence, kinetics, and toxicology of MX. As there is a lack of knowledge on human toxicity and human carcinogenicity of MX, a final evaluation of the toxicological data with regard to public health is still impossible. Nevertheless, in view of the published data about MX, there is no evidence for any substantial human risk at the moment.

Contact allergy to fragrances: frequencies of sensitization from 1996 to 2002. Results of the IVDK*.

Increasing frequencies of sensitization to the fragrance mix (FM) have been acknowledged as a serious problem for many years. It is well known that the single compounds (SCs) of the FM contribute differently to the FM patch rest reactions. In this study, we were interested in the time trends of the FM, the SCs, Myroxylon pereirae resin (MP; balsam of Peru) and oil of turpentine (OT) as possible further indicators of perfume allergy and analysed the data collected by the Information Network of Departments of Dermatology multicentre project from 1996 to 2002. During the study period (1996-2002), the FM [8% petrolatum (pet.)], MP (25% pet.) and OT (1% pet.) were tested in 59,298, 59,334 and 59,478 patients, respectively. SCs were tested in a selected group of patients, ranging from n = 1083 to n = 1924 per year. A significant increase in the proportions of patients with positive reactions to FM, MP and OT between 1996 and 1998 is noted, and a significant decline from 1999 to 2002 (Cochrane Armitage trend test, P < 0.0001). The highest frequency of sensitization to the FM was 13.1% in 1999, and the lowest 7.8% in 2002. The number of concomitant reactions to OT, a surrogate marker for terpenes, in FM-positive patients was significantly increased between 1997 and 1999. Reactions to SCs in FM-positive patients were observed in 29.9% (oak moss absolute) to 5.9% (geraniol). There was no time trend in reactions to SCs, although the relative share was increased for isoeugenol, cinnamic aldehyde and geraniol in 1999. In summary, we report for the first time, a significant decline in sensitization to the FM, very probably due to a reduced exposure (less potent allergens used in fine fragrances, possibly less use of natural ingredient-based cosmetics and lowered use concentration of important fragrance allergens). The differences in ranking of SCs could stimulate (a) a redefinition of the FM and (b) a differentiated preventive and regulatory approach, with oak moss and isoeugenol being regulated strictly by prohibition, concentration limits further reconsidered and/or health warnings and clearly less noxious substances like geraniol treated less restrictively.

Mucosal symptoms elicited by fragrance products in a population-based sample in relation to atopy and bronchial hyper-reactivity.

BACKGROUND: Exposure to perfume and fragrance products may, in some individuals, cause symptoms from the eyes and airways. The localization, character and risk factors of such symptoms in the general population are unknown. OBJECTIVE: To investigate both the localization and character of symptoms from the eyes and airways elicited by fragrance products, and the associations between such symptoms and skin prick test reactivity (atopy), methacholine bronchial hyper-reactivity (BHR), allergic rhinitis and asthma. METHODS: A questionnaire on mucosal symptoms elicited by fragrance products was posted to 1189 persons who had participated in a Danish population-based study of allergic diseases in 1997/1998. The study included measurement of BHR, atopy, forced expiratory volume in 1 s (FEV1), and serum eosinophilic cationic protein (serum ECP). RESULTS: The response rate was 79.6%. Symptoms from the eyes or airways elicited by fragrance products were reported by 42%. BHR (adjusted odds ratio 2.3, 95% confidence interval 1.5-3.5) was independently associated with symptoms from the eyes and airways elicited by fragrance products. There were no significant associations between these symptoms and atopy, FEV1 or serum ECP. CONCLUSIONS: Mucosal symptoms from the eyes and airways were common in this population. BHR was a significant and independent predictor of these symptoms. The lack of association with atopy suggested that IgE-mediated allergic mechanisms do not play a major role in the development of these symptoms.

Flowers and other trigger factors in asthma and rhinitis--an inquiry study.

Six hundred and eighty adult patients with asthma and/or rhinitis were questioned about symptoms elicited by 46 different flowers and 10 common non-specific environmental trigger factors listed in a questionnaire. Flowers or birch twigs were reported to elicit symptoms in 79% of the patients, somewhat more often in rhinitis than in asthma patients, and caused symptoms as often in non-atopics as in atopics. Birch twig and marguerite most frequently induced symptoms, followed by strongly smelling flowers such as hyacinth, lilac, and lily of the valley. Unspecific irritants caused symptoms in 98% of the asthmatics and in 67% of patients with rhinitis. Tobacco smoke and perfumes were the most important troublemakers. A significant positive correlation was found for elicitation of symptoms from flowers and from certain non-specific irritants. It is concluded that non-specific hyperreactivity as well as reaginic hypersensitivity are the mechanisms involved when birch twigs and flowers elicit symptoms.

Berloque dermatitis - a continuing cosmetic problem.

Despite the decline in the incidence of berloque dermatitis during the past decade, milder cases resulting from the presence of relatively small quantities of bergapten in perfumed cosmetics continue to occur. The resultant hyperpigmentation may have an atypical presentation leading to error in diagnosis. In addition, the condition can sometimes induce or aggravate melasma and may be responsible for other pigmentary disorders of the face and neck of questionable etiology such as poikiloderma of Civatte, Riehl's melanosis and pigmented peribuccal erythema of Brocq.

Studies on contact hypersensitivity in the guinea pig.

A method to determine the quantitative induction and challenge of the allergenicity of externally applied toiletories and cosmetics, including their components, is described. The experiment used oil-soluble cinnamic aldehyde and water-soluble formalin as allergens, and guinea pigs as the experimental animals. A high sensitization method resulted, carried out as follows. A 24-h closed patch is attached to the skin every other day over a period of 2 weeks (a total of 4 applications). Freund's complete adjuvant is administered intradermally just before the 3rd application of the patch. The challenge step is performed by directly applying the test material. This method was compared with other allergenicity evaluation methods. As a result, this method was found to be in no way inferior in sensitization performance to the other methods. The method was used on perfume mixtures and tested for its evaluation effectiveness. It proved to be satisfactory.

Standard photopatch testing with Musk Ambrette.

495 patients were standard photopatch tested with Musk Ambrette 5% in petrolatum and in dimethyl phthalate. 4 cases gave positive photopatches; 3 were men and 1 a woman. 2 cases, both men, had current or past relevant reactions to Musk Ambrette presented with typical perfume dermatitis. The other 2 cases had positive reactions to Musk Ambrette of uncertain relevance. Photoallergic reaction to Musk Ambrette is a rare event. Only a few relevant reactions will be missed by excluding it from standard phototesting.

24 and 48 h allergen exposure in patch testing. Comparative study with 11 common contact allergens and NiCl2.

Patch test reactions to 11 common contact allergens were studied after 24 h and 48 h occlusion with Finn Chambers in 390 patients. Concordant allergic results were found in 96 cases (74%). In 22 patients (17%), the reaction was positive only after 48 h and in 11 cases (8.5%) only after 24 h exposure. Most of the discordant reactions were to nickel, cobalt, neomycin, formaldehyde and perfume mix. Irritant reactions were found in 55 cases, the majority occurring after 48 h occlusion. Nickel chloride tested in parallel with 48 h exposure lead to more positive allergic and toxic reactions than nickel sulphate.

Immediate and delayed reactions to cosmetic ingredients.

The purpose of this study was to investigate the incidence and etiology of cutaneous reactions caused by cosmetics, with an emphasis on perfume sensitivity. 19 control subjects and 31 patch test clinic patients (16 with a history of adverse cosmetic reactions) were examined for sensitivity by history, open and patch testing using the North American Contact Dermatitis Group (NACDG) fragrance screening series and 11 other common allergens found in cosmetics. Contact urticaria was very frequent to certain chemicals; however, patients with a history of cosmetic sensitivity were not found to have a significant increase in positive reactions when compared to controls or patients with eczematous skin. 12 subjects had positive patch test reactions, most of which were not clinically relevant. 3 patients with a history of cosmetic sensitivity had positive reactions, only 1 of which was in the fragrance screening series (cinnamic alcohol). There were 6 reactions in patients with eczematous skin, 4 of which were to preservatives. 3 controls had positive reactions, each to thimerosal. A history of cosmetic sensitivity was not confirmed by open and closed skin testing in our subjects.

Airborne pigmented contact dermatitis due to musk ambrette in incense.

We reported 2 patients with pigmented contact dermatitis caused by occupational airborne contactants, whitening dyes in clothes and formaldehyde in packing adhesive tapes. A women developed airborne pigmented contact dermatitis due to musk ambrette in incense. Patch testing confirmed the diagnosis. Since olden times, people in Japan have burnt incense when they worshipped their ancestors. Recently, it has been in fashion to enjoy perfumes and people may burn incense all day long every day. Our patient burnt 2 kinds of incense every day for about 5 years. We assumed musk ambrette was volatilized when incense was burnt, and contact on her face being dissolved in sebum, thus inducing allergic pigmented contact dermatitis.

Wood tars allergy, cross-sensitization and coal tar.

In a population of 1883 patients tested for allergic contact dermatitis (1985-1988), a prevalence of 5.4% (103 cases) was seen for wood tars (ICDRG allergen, 12% pet.) sensitization. In this group (n = 103), retrospectively, a combined allergy was seen to wood tars and fragrance mix in 43% and to wood tars and balsam of Peru in 31%. A combined allergy to wood tars and coal tar was seen in 19 patients (18.5%): 14 to liquor carbonis detergens (LCD), 8 to lianthral and 3 to both LCD and lianthral. Within the group with wood tars allergy (n = 103), a minority (n = 37) had a history of atopic dermatitis. Comparison of the test results in atopic and non-atopic subgroups (within the group of 103) revealed a higher incidence of combined wood tars-fragrance mix allergy in the atopic group (n = 37). In this group, a lower incidence of combined wood tars-coal tar sensitization was seen in comparison with the non-atopic group (n = 66). The authors believe that combined "wood tars-coal tar" allergy could be the consequence of cross-sensitization rather than due to long-term previous topical treatment with tar derivatives. The high % of cross-allergy between wood tars and fragrance mix emphasizes the role of wood tars as an important indicator allergen in perfume allergy.

Sensitization to fragrance materials in Indonesian cosmetics.

2 different groups of patients were patch tested with 2 test series (A and B) containing extracts of fragrance raw materials, traditionally used in Indonesian cosmetics. Series A consisted of diluted extracts of commercially available Indonesian fragrances. Series B consisted of extracts prepared in our department from corresponding indigenous flowers and fruits. Group 1 consisted of 32 patients positive to fragrance-mix, of whom 8 (25%) had positive tests to 1 or more of the different extracts of fragrance raw materials. Reactions were observed to extracts of: Rosa hybrida Hort (7); Canangium odoratum Baill (5); Citrus aurantifolia Swingle (4); Jasminum sambac Ait (2). 6 of the 8 patients had reactions to 1 or more of the components of fragrance-mix: oakmoss (3); cinnamic alcohol (2), isoeugenol (1); cinnamic aldehyde (1) and geraniol (1). Group 2 consisted of 159 patients patch tested on suspicion of contact dermatitis, who were fragrance-mix negative. Only 2 (1.2%) had a positive patch test to the extracts of fragrance raw materials. Specimens taken (as is) from the flowers and citrus fruits (being the basis sources of the fragrance raw materials) were less antigenic. The use of additional test series in Indonesia to detect allergy to traditional cosmetics and perfumes merits further investigation.

Quantitative aspects of isoeugenol contact allergy assessed by use and patch tests.

The clinical implications of sensitization to the fragrance material isoeugenol were studied in 19 subjects. Patch testing with serial dilutions of isoeugenol and a repeated open application test (ROAT) were performed. The minimum effect level under patch test conditions was below 0.01% isoeugenol in 4/19 (20%) of the test subjects. The ROAT was performed with a test solution of 0.2% isoeugenol in ethanol, which is the recommended maximum concentration used in perfumes, ethanol being applied as vehicle control. 4 weeks was the maximum exposure period. The upper arm was used as test site the 1st 14 days and the upper arm as well as the neck for the next 14 days. 12/19 (63%) of test subjects had a positive ROAT. 4 of the responders (33%) reacted beyond day 7, but none after day 14. Use testing on the neck 14 days did not add any further ROAT-positive cases, compared with testing on the upper arm. The sensitivity found on patch testing may be a guidance for the outcome of use tests with the same compound. In this study, all subjects with a positive use test to isoeugenol 0.2% in ethanol also demonstrated on patch testing a minimum effect level of 0.2% or lower. Data from serial dilution patch and use tests may contribute significant information to assessment of the relationship between patch test responses and clinical contact hypersensitivity, and thus the safety of allergens used in cosmetics.

Deodorants on the European market: quantitative chemical analysis of 21 fragrances.

Deodorants are one of the most frequently used types of cosmetics and side-effects from them are common. Recent studies relate perfume allergy to this type of product. 73 deodorants were analyzed by gas chromatography--mass spectrometry for the determination of the contents of 7 wellknown fragrance allergens from the fragrance mix and 14 other commonly used fragrance materials. The deodorants were purchased at retail outlets in 5 European countries. It was found that in general, fragrance mix ingredients were more frequently present in vapo- and aerosol sprays than in roll-on products. The levels of the fragrance mix substances ranged from 0.0001-0.2355%. The products investigated contained cinnamic aldehyde and isoeugenol less frequently (17% and 29% respectively), and eugenol and geraniol most frequently (57% and 76% respectively). The 14 other fragrance materials were found in 40-97% of the deodorants, with hedione and benzyl acetate the most frequently found substances. The concentration of these 14 substances ranged from 0.0001-2.7%. It is concluded that the levels of cinnamic aldehyde and isoeugenol found in the deodorants could prove to be relevant for elicitation of contact dermatitis. No conclusions could be drawn about the other fragrance mix constituents, as threshold levels in sensitized individuals have not been investigated. Furthermore, all of the fragrance materials investigated were frequently found in deodorants and, apart from the fragrance mix ingredients, the extent of problems with sensitization to these fragrance materials is largely unknown.
