MYROXYLON PEREIRAE OIL.

Avoid CAS 8007-00-9 / FRAGRANCE

Myroxylon pereirae oil, commonly known as Balsam of Peru, is an ingredient with historical applications in topical medicine for its antiseptic, anti-inflammatory, and wound-healing properties. Despite these traditional uses, its primary modern role in cosmetics is for masking and fragrance due to its distinctive aroma. However, its significant allergenic potential and stringent regulatory restrictions severely limit its safe and advisable inclusion in precision skincare formulations.

0.4%

Myroxylon pereirae oil is primarily valued for its aromatic properties, serving as a fragrance or masking agent in cosmetic formulations. Its high allergenic potential necessitates a strict maximum concentration of 0.4%. Given its significant safety concerns as a major allergen, inclusion at any level, particularly approaching the maximum permitted, is considered 'dusting' if its purpose is not demonstrably linked to a primary, non-fragrance skincare benefit substantiated by robust clinical data.

Sensitization risk High

Myroxylon pereirae oil is identified as a major allergen and a primary sensitizer, frequently implicated in allergic contact dermatitis. Its use in cosmetics, particularly as a fragrance ingredient, is highly restricted. Extracts and distillates are permitted at a total concentration not exceeding 0.4% in cosmetic products. The crude form is specifically prohibited for fragrance use in cosmetics. While the FDA has approved it for limited use in food, its application in cosmetics is viewed with caution by regulatory bodies like EWG due to its allergenic profile.
