Poly C10-30 ●
TL;DR. This ingredient is a synthetic film-former and texture modifier that helps products spread evenly, form a flexible coating, and improve water resistance or hold.
What does Poly C10-30 do in a cosmetic formula?
This ingredient is a synthetic film-former and texture modifier that helps products spread evenly, form a flexible coating, and improve water resistance or hold.
Is Poly C10-30 clean?
From a clean-beauty perspective, it is usually flagged because it is a synthetic polymer rather than because of direct skin irritation. It is generally low in skin reactivity due to its large molecular size, but some standards scrutinize residual monomers and polymeric film-formers.
Is Poly C10-30 sustainable?
This material is typically petroleum-derived and is not considered readily biodegradable. Its main sustainability concern is environmental persistence after rinse-off or disposal.
Is Poly C10-30 COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic standards, which restrict synthetic petrochemical polymers of this type. From a Green Chemistry perspective, it scores weakly on renewable sourcing and end-of-life biodegradability, even though it can deliver performance at low use levels.
How does Poly C10-30 work chemically?
The molecule is a high-molecular-weight ester polymer with long C10 to C30 alkyl side chains, giving it film-forming, water-resistant, and slip-enhancing behavior. It is typically stable across common cosmetic pH ranges and is used at low percentages, often alongside emulsifiers, oils, or UV-filter systems to improve film uniformity.
