Avoid CAS 9000-64-0 / FILM FORMING, FRAGRANCE, HAIR CONDITIONING

Myroxylon Balsamum Resin, also known as Peru Balsam, is a naturally derived substance historically utilized for its antimicrobial and skin-healing properties. However, its significant propensity to cause allergic contact dermatitis and sensitization warrants strict limitations on its use in cosmetic formulations.

Science

Mechanism of Action

This resin exhibits mild bactericidal, fungicidal, and antiseptic activities, attributed to components such as benzoic and cinnamic acids and their esters. It is also noted for its potential to stimulate capillary beds and enhance skin penetration, mechanisms supporting its traditional use in minor wound care.

25%

A 25% concentration of Peru balsam in patch testing frequently induces allergic contact dermatitis, indicating a substantial risk of sensitization. Regulatory bodies like the SCCS and IFRA have imposed restrictions due to its classification as a known human toxicant and allergen, making it unsuitable for a precision skincare approach.

Stability

As a resinous material with a significant volatile oil content (cinnamein) and various organic acids and esters, Myroxylon Balsamum Resin is oil-soluble and generally stable under typical cosmetic formulation conditions. It becomes more pourable upon heating.

Conflicts

  • Known to cause allergic contact dermatitis and sensitization, particularly in individuals sensitive to fragrances. It contains several prominent allergenic compounds, including isoeugenol, eugenol, and cinnamyl alcohol.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk High

The Scientific Committee on Consumer Safety (SCCS) has identified Peru balsam as posing a high risk of sensitization to consumers. Consequently, both the EU Cosmetics Directive and the International Fragrance Association (IFRA) have restricted its use and concentration in cosmetics due to documented concerns regarding allergies, immunotoxicity, and potential for human toxicity. It no longer holds FEMA GRAS™ status for food additives.
