The Formula
Formulation
Stability
Poly(butylene succinate-co-adipate) is known to undergo hydrolytic degradation, with studies noting this process can occur at pH levels around 10.6. Furthermore, certain PBS-based copolyesters with acidic groups have demonstrated instability and a significant deterioration in mechanical strength during storage, suggesting potential formulation challenges.
Safety
Safety Profile
While safety assessments exist for the individual monomers (1,4-butanediol and adipic acid) in non-cosmetic contexts, such as food contact materials (e.g., FDA estimates for 1,4-butanediol suggest safety at exposures not exceeding 90 micrograms per person per day), there are no direct safety reviews by the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) specifically for this copolymer in cosmetic applications.
