PEG-12 Dimethicone/PPG- 20 Crosspolymer ●
TL;DR. This ingredient is a texture modifier and emulsifying stabilizer, especially for water-in-oil and water-in-siloxane systems. It helps build a smooth gel network, improve slip, and keep water and oil phases evenly dispersed.
What does PEG-12 Dimethicone/PPG- 20 Crosspolymer do in a cosmetic formula?
This ingredient is a texture modifier and emulsifying stabilizer, especially for water-in-oil and water-in-siloxane systems. It helps build a smooth gel network, improve slip, and keep water and oil phases evenly dispersed.
Is PEG-12 Dimethicone/PPG- 20 Crosspolymer clean?
From a clean-beauty perspective, it often faces restriction because it is a synthetic crosslinked polymer with PEG and PPG units. Skin tolerance is generally good, but frameworks may flag trace ethoxylation-related residues and its broader clean-standard fit.
Is PEG-12 Dimethicone/PPG- 20 Crosspolymer sustainable?
This material is synthetic and based on petrochemical and mineral-derived inputs rather than renewable feedstocks. It is not considered readily biodegradable, so environmental persistence is the main sustainability concern.
Is PEG-12 Dimethicone/PPG- 20 Crosspolymer COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its synthetic polymer structure, PEG/PPG chemistry, and limited biodegradability give it weak alignment with Green Chemistry priorities.
How does PEG-12 Dimethicone/PPG- 20 Crosspolymer work chemically?
The molecule is a crosslinked siloxane-polyether network, combining a flexible inorganic-organic backbone with hydrophilic polyether segments for interfacial stabilization. It is typically used at low single-digit percentages, is broadly pH-stable in finished emulsions, and is not prone to rancid oxidation like unsaturated plant oils.
