Trimethylsiloxysilylcarbamoyl Pullulan ●
TL;DR. This ingredient is primarily a film-former used to improve wear, adhesion, gloss, and water resistance in makeup, sunscreen, and long-wear skin products.
What does Trimethylsiloxysilylcarbamoyl Pullulan do in a cosmetic formula?
This ingredient is primarily a film-former used to improve wear, adhesion, gloss, and water resistance in makeup, sunscreen, and long-wear skin products.
Is Trimethylsiloxysilylcarbamoyl Pullulan clean?
From a clean-beauty perspective, it has friction because many standards screen organosilicon polymers out of natural-positioned formulas. Skin irritation concern is generally low due to its high molecular weight, but it may not meet stricter restricted-list expectations.
Is Trimethylsiloxysilylcarbamoyl Pullulan sustainable?
This material is based on a carbohydrate polymer that is chemically modified with organosilicon groups, so its sourcing profile is mixed. Biodegradability is less straightforward than the unmodified natural polymer, and environmental persistence questions are the main sustainability concern.
Is Trimethylsiloxysilylcarbamoyl Pullulan COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic because it is a synthetic organosilicon-modified polymer rather than an allowed natural-derived transformation. Its Green Chemistry alignment is limited by the synthetic modification and uncertain end-of-life biodegradation.
How does Trimethylsiloxysilylcarbamoyl Pullulan work chemically?
The molecule is a high-molecular-weight polysaccharide derivative bearing hydrophobic organosilicon substituents, which helps it form flexible, water-resistant films on skin or hair. It is typically used at low levels in color cosmetics and sunscreens, and it is chosen when formulators need film integrity without relying only on conventional synthetic acrylate resins.
