Polyglyceryl-3 Disiloxane Dimethicone ●
TL;DR. This ingredient functions mainly as a silicone-based emulsifier and conditioning agent, helping water and oil phases mix while adding slip, spreadability, and a smooth afterfeel. It is often used in skin care, makeup, and hair products that need a lightweight, silky texture.
What does Polyglyceryl-3 Disiloxane Dimethicone do in a cosmetic formula?
This ingredient functions mainly as a silicone-based emulsifier and conditioning agent, helping water and oil phases mix while adding slip, spreadability, and a smooth afterfeel. It is often used in skin care, makeup, and hair products that need a lightweight, silky texture.
Is Polyglyceryl-3 Disiloxane Dimethicone clean?
From a clean-beauty perspective, this material has significant friction because many standards restrict or exclude synthetic silicone materials. Its concern profile is less about routine skin irritation and more about persistence, biodegradation, and alignment with restricted-list policies.
Is Polyglyceryl-3 Disiloxane Dimethicone sustainable?
This material is synthetic and relies on an organosilicon backbone, typically linked to mineral-derived silicon and petrochemical processing inputs. It is not considered readily biodegradable, so wastewater and sediment persistence are the main sustainability concerns.
Is Polyglyceryl-3 Disiloxane Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because it falls outside the allowed categories for natural and naturally derived cosmetic ingredients. Its Green Chemistry fit is weak due to synthetic processing, limited biodegradability, and environmental persistence concerns.
How does Polyglyceryl-3 Disiloxane Dimethicone work chemically?
The molecule is an amphiphilic organosilicon surfactant with hydrophilic glycerol-derived groups attached to a hydrophobic, flexible backbone, which explains its emulsifying and sensory role. It is generally stable across typical cosmetic pH ranges and is used at low formulation levels alongside oils, waxes, pigments, or other emulsifiers to improve dispersion and feel.
