Polyglycerin-2 Isosteate/Dimer DilinoleateI Copolymer ●
TL;DR. This ingredient is an oil-soluble dispersant, emulsifying aid, and film-forming conditioner, especially useful in lip, color, and balm formulas. It helps wet pigments, improve payoff, add cushion, and stabilize oil-rich textures.
What does Polyglycerin-2 Isosteate/Dimer DilinoleateI Copolymer do in a cosmetic formula?
This ingredient is an oil-soluble dispersant, emulsifying aid, and film-forming conditioner, especially useful in lip, color, and balm formulas. It helps wet pigments, improve payoff, add cushion, and stabilize oil-rich textures.
Is Polyglycerin-2 Isosteate/Dimer DilinoleateI Copolymer clean?
From a clean-beauty perspective, it is generally well tolerated and is not a common allergen or preservative-related flag. The main scrutiny is that it is a chemically built polymer, so acceptance can vary by retailer or certification standard.
Is Polyglycerin-2 Isosteate/Dimer DilinoleateI Copolymer sustainable?
This material is commonly made from glycerin and vegetable-oil fatty acid feedstocks, although the exact renewable content depends on the supplier. Its ester-rich structure is expected to break down more readily than many silicone or acrylic film-formers, but public biodegradation data is limited.
Is Polyglycerin-2 Isosteate/Dimer DilinoleateI Copolymer COSMOS-approved?
It may be compatible with COSMOS-natural when made from approved natural-origin feedstocks using allowed reactions such as esterification and polycondensation, but supplier documentation is needed. In Green Chemistry terms, it scores better when renewable fatty acids and glycerin are used, with the main caveat being polymer processing and limited end-of-life data.
How does Polyglycerin-2 Isosteate/Dimer DilinoleateI Copolymer work chemically?
Chemically, this is a branched, oil-soluble polyester built from polyglycerol units and long-chain C18 fatty structures, giving it both polarity for pigment wetting and lipophilicity for oil-phase compatibility. It is typically used around 1 to 10% in anhydrous color cosmetics and lip products, and it is most stable in oil phases, with ester hydrolysis more likely under strong acid or alkaline conditions.
