Polyester-27

TL;DR. This ingredient is primarily used as a synthetic film-former and binder, helping products create a smooth, flexible coating on skin, hair, nails, or pigments. It can support wear, adhesion, and texture in color cosmetics, styling products, and long-wear formulas.

What does Polyester-27 do in a cosmetic formula?

This ingredient is primarily used as a synthetic film-former and binder, helping products create a smooth, flexible coating on skin, hair, nails, or pigments. It can support wear, adhesion, and texture in color cosmetics, styling products, and long-wear formulas.

Is Polyester-27 clean?

From a clean-beauty perspective, this material has friction because it is a synthetic polymer and may be flagged by standards that restrict non-biodegradable plastic-like film formers. It is not mainly an irritation concern, but its polymer status and end-of-life profile make it less aligned with stricter clean frameworks.

Is Polyester-27 sustainable?

This material is typically petrochemical-derived or partly petrochemical-derived and is not generally regarded as readily biodegradable. Its sustainability concern is environmental persistence rather than acute skin compatibility.

Is Polyester-27 COSMOS-approved?

This ingredient is not aligned with COSMOS-natural or COSMOS-organic principles because it is a synthetic polymer outside the usual permitted naturally derived material set. Its Green Chemistry fit is weak due to nonrenewable feedstock reliance and limited biodegradability data.

How does Polyester-27 work chemically?

This compound is a high-molecular-weight ester-based polymer, designed to deposit as a continuous film rather than penetrate skin. It is generally used at low to moderate formula levels according to the desired film strength, and performance depends on solvent compatibility, resin dispersion, and plasticizer or co-film-former selection.
