Polyglyceryl-2 Sesquicaprylate ●
TL;DR. This ingredient is a nonionic emulsifier and solubilizer that helps blend oil and water phases, stabilize light emulsions, and disperse fragrance or oil-soluble actives. It can also support mild cleansing systems and improve preservation performance in some formulas.
What does Polyglyceryl-2 Sesquicaprylate do in a cosmetic formula?
This ingredient is a nonionic emulsifier and solubilizer that helps blend oil and water phases, stabilize light emulsions, and disperse fragrance or oil-soluble actives. It can also support mild cleansing systems and improve preservation performance in some formulas.
Is Polyglyceryl-2 Sesquicaprylate clean?
From a clean beauty perspective, it is generally well accepted because it has low sensitization concern and no common restricted-list friction. At higher surfactant levels, it may contribute to mild eye or skin irritation, so formula context matters.
Is Polyglyceryl-2 Sesquicaprylate sustainable?
This material is commonly made from vegetable-derived glycerin building blocks and medium-chain fatty acids, with coconut or palm-kernel sourcing possible. It is expected to be readily biodegradable, but palm-linked supply chains benefit from certified sourcing.
Is Polyglyceryl-2 Sesquicaprylate COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic formulas when made from approved feedstocks using allowed processing. Its renewable carbon content, biodegradability, and non-ethoxylated chemistry give it a strong Green Chemistry profile.
How does Polyglyceryl-2 Sesquicaprylate work chemically?
The molecule is an amphiphilic nonionic ester with multiple hydroxyl groups on the water-compatible side and medium-chain alkyl groups on the oil-compatible side. Typical use is about 0.5 to 3% for emulsifying or solubilizing, and it is broadly stable across normal cosmetic pH ranges, although strong acid or alkaline conditions can slowly cleave ester bonds.
