“…[105][106][107] It was also noted that there are millions of oat-containing products on the market and very few cases of allergic contact dermatitis to oats reported. 108,109 These authors noted their own experiment in which oat colloidal extract was unable to trigger any immunization reaction in mice with atopic dermatitis. 107 They proposed that a study on a large population of atopic children with repeated long-term use of emollients with and without A sativa-derived ingredients would be needed before coming to the conclusion proposed by the authors of the history survey.…”

This is a safety assessment of Avena sativa (oat)–derived ingredients. The reported functions of these ingredients in cosmetics include abrasives, antioxidant, skin conditioning agents, absorbents, and bulking agents. The Panel reviewed relevant animal and human data related to these ingredients. Because final product formulations may contain multiple botanicals, each containing the same constituents of concern, formulators are advised to be aware of these constituents and to avoid reaching levels that may lead to sensitization or other toxic effects. The Panel stated that industry should continue to use good manufacturing practices to limit impurities and concluded that all but one of the Avena sativa (oat)–derived ingredients are safe as cosmetic ingredients in the practices of use and concentration described in this safety assessment when formulated to be nonsensitizing; data are insufficient to come to a conclusion of safety for Avena Sativa (Oat) Meristem Cell Extract.

“…Immunoblot analysis of the patient's serum detected IgE antibodies that reacted with proteins of 10,000 to 20,000 kDa, corresponding to codfish elastin. A case of contact urticaria to oats contained in an emollient cream has been reported [41].…”

Occupational contact dermatitis is generally caused by haptens but can also be induced by proteins causing mainly immunological contact urticaria (ICU); chronic hand eczema in the context of protein contact dermatitis (PCD). In a monocentric retrospective study, from our database, only 31 (0.41%) of patients with contact dermatitis had positive skin tests with proteins: 22 had occupational PCD, 3 had nonoccupational PCD, 5 occupational ICU and 1 cook had a neutrophilic fixed food eruption (NFFE) due to fish. From these results and analysis of literature, the characteristics of PCD can be summarized as follows. It is a chronic eczematous dermatitis, possibly exacerbated by work, suggestive if associated with inflammatory perionyxix and immediate erythema with pruritis, to be investigated when the patient resumes work after a period of interruption. Prick tests with the suspected protein-containing material are essential, as patch tests have negative results. In case of multisensitisation revealed by prick tests, it is advisable to analyse IgE against recombinant allergens. A history of atopy, found in 56 to 68% of the patients, has to be checked for. Most of the cases are observed among food-handlers but PCD can also be due to non-edible plants, latex, hydrolysed proteins or animal proteins. Occupational exposure to proteins can thus lead to the development of ICU. Reflecting hypersensitivity to very low concentrations of allergens, investigating ICU therefore requires caution and prick tests should be performed with a diluted form of the causative protein-containing product. Causes are food, especially fruit peel, non-edible plants, cosmetic products, latex, animals.Key words: protein contact dermatitis, chronic hand eczema, prick test, protein allergy, immunological contact urticaria, neutrophilic fixed food eruption O ccupational contact dermatitis is generally caused by haptens but it can also be induced by proteins causing immunological contact urticaria (ICU), chronic hand eczema in the context of protein contact dermatitis (PCD) or less common skin conditions. We report the results of a retrospective study on occupational protein dermatitis carried out in our dermatology and allergology department and provide an update on the characteristics of occupational skin diseases induced by proteins and on the causative factors found in our study and in a review of literature.

“…Used for more than 4 decades in atopic dermatitis treatment, the local and systemic tolerance to oat-based emollients has always been excellent. However, their safety was recently challenged by several reports of allergic contact dermatitis and contact urticaria to oats in atopic adults and children [9,10,11,12,13]. Since sensitization to oats, and more generally to cereals, is high in atopic patients [13], these observations raised the concern that oat cosmetics may be endowed with allergenic properties.…”

Tolerance of Oat-Based Topical Products in Cereal-Sensitized Adults with Atopic Dermatitis

Background: Few data suggest oat-based cosmetics may cause allergic reactions in atopic subjects, especially when sensitized to cereals. Objectives: To evaluate the risk of immediate and delayed allergic reactions to repeated and maximized applications (RMA) of oat-containing cosmetics and oat extracts and their tolerance in cereal-sensitized atopic adults. Methods: Open-label pilot study in 12 cereal-sensitized atopic adults over 45 days. Open tests and RMA were performed with Rhealba® oat-containing cosmetics at day 0 (D0) and D10, and from D10 to D31. Patch and prick tests were performed at D7 and D42 with wheat and Rhealba oat extracts and the study cream. Results: The RMA of oat-based cosmetics in cereal-sensitized atopic adults did not induce any immediate or delayed allergic reaction and was well tolerated. No immediate or delayed positive skin test to oat extracts was observed. Conclusion: Sensitization to cereals does not increase the risk of allergic reactions to oat-containing cosmetics.
