Legislative update: Regulating ingredients in personal care products

Allergic contact dermatitis from shellac in an ecological hair spray occurring in a patient with frontal fibrosing alopecia

“…Before the introduction of film coating, a combination of shellac, cetostearyl alcohol, and stearic acid was used as an enteric coating, that is, aqueous shellac solution used for drug delivery to the colon. It remains important that legislative regulation 6 also continues to consider organic personal care products, since these may evidently contain substances with sensitizing potential. Although the relationship between (cosmetic) contact allergy and associated scalp dermatitis might be straightforward, as in the present case, its potential link with FFA remains unclear, indicating that more research is needed.…”
