Stability
While general polyester materials demonstrate robust stability across a wide pH range (e.g., pH 1-13 for PET fabrics) and good resistance to acids and alkalis, specific stability data for POLYESTER-21 in cosmetic matrices is currently unavailable.
Safety
Safety Profile
Formal safety evaluations by prominent bodies like the Cosmetic Ingredient Review (CIR), Scientific Committee on Consumer Safety (SCCS), or the FDA specifically for POLYESTER-21 are currently absent. Broadly, polyester polymers are widely utilized, and certain cross-linked polyester resins are deemed safe by the FDA for repeated food contact within specific extractive limits, suggesting a general low concern for the class, but this does not directly translate to POLYESTER-21 in cosmetic applications.
