Science
Mechanism of Action
This ingredient functions primarily as a film-forming agent, establishing a cohesive layer upon application to the skin, hair, or nails. Beyond this, it can also enhance the overall texture and stability of a cosmetic formulation, and potentially optimize the delivery and penetration of other incorporated ingredients.

Stability
While general polyester-based materials have demonstrated broad pH stability, typically resisting acids and alkalis across a range of pH 1-13 in some textile applications, specific stability data for POLYESTER-27 as a cosmetic ingredient is not readily available.
Conflicts
- Risk of irritation increases when combined with other problematic ingredients.
Safety
Safety Profile
POLYESTER-27 has not undergone specific safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel or the Scientific Committee on Consumer Safety (SCCS). While general polyesters are studied for medical uses, specific cosmetic ingredient safety data for POLYESTER-27 is limited. There is a likelihood of irritation, which may increase when combined with other problematic ingredients, potentially leading to inflammation or dryness.

Verdict
POLYESTER-27 offers film-forming and textural benefits to formulations; however, its unreviewed safety status by major cosmetic bodies and the noted potential for irritation, especially in combination with other ingredients, necessitate cautious evaluation for precision skincare applications.
