Polyglyceryl-10 Pentaisostearate ●
TL;DR. This ingredient primarily acts as a nonionic emulsifier, helping blend oils into water-based systems and stabilize creams, lotions, cleansing balms, and makeup removers. It can also improve slip and help solubilize lipophilic ingredients.
What does Polyglyceryl-10 Pentaisostearate do in a cosmetic formula?
This ingredient primarily acts as a nonionic emulsifier, helping blend oils into water-based systems and stabilize creams, lotions, cleansing balms, and makeup removers. It can also improve slip and help solubilize lipophilic ingredients.
Is Polyglyceryl-10 Pentaisostearate clean?
It is generally well tolerated and does not carry common clean-standard flags for allergens, sensitizers, or restricted preservatives. Clean-beauty scrutiny is usually limited to feedstock transparency and residual processing impurities, not the molecule’s routine use profile.
Is Polyglyceryl-10 Pentaisostearate sustainable?
This material is typically made from glycerin-derived building blocks and fatty acid feedstocks that may be vegetable sourced, with palm supply-chain transparency sometimes relevant. It is expected to be readily or ultimately biodegradable and is not known for environmental persistence.
Is Polyglyceryl-10 Pentaisostearate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from approved renewable feedstocks and allowed esterification chemistry. Its profile fits Green Chemistry reasonably well because it can use plant-derived inputs, avoids ethoxylation, and has a favorable biodegradability profile.
How does Polyglyceryl-10 Pentaisostearate work chemically?
The molecule is a large nonionic ester with a hydrophilic polyol backbone and multiple branched C18 lipophilic chains, giving it strong oil-binding and emulsifying behavior. It is usually stable across typical cosmetic pH ranges and is often used with co-emulsifiers or fatty alcohols to tune viscosity, lamellar structure, and rinse feel.
