Dimethicone/Bis-lsobutyl PPG-20 Crosspolymer ●
TL;DR. This ingredient is a crosslinked texture agent, film-former, and viscosity modifier that gives slip, cushioning, blurring, and gel structure in creams, primers, sunscreens, and makeup.
What does Dimethicone/Bis-lsobutyl PPG-20 Crosspolymer do in a cosmetic formula?
This ingredient is a crosslinked texture agent, film-former, and viscosity modifier that gives slip, cushioning, blurring, and gel structure in creams, primers, sunscreens, and makeup.
Is Dimethicone/Bis-lsobutyl PPG-20 Crosspolymer clean?
Clean-beauty frameworks often flag it because it is a non-biodegradable synthetic polymer and may carry trace low-molecular-weight cyclic residues controlled by specifications. Skin irritation potential is generally low because the molecule is large and chemically inert.
Is Dimethicone/Bis-lsobutyl PPG-20 Crosspolymer sustainable?
It is made from mineral-derived silicon chemistry and petrochemical polyether or alkyl inputs rather than renewable feedstocks. It is not readily biodegradable and can persist as polymeric material in wastewater and sediments.
Is Dimethicone/Bis-lsobutyl PPG-20 Crosspolymer COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic as a synthetic crosslinked polymer from chemistry outside the standard’s allowed material set. From a Green Chemistry lens, the main drawbacks are non-renewable inputs, limited biodegradability, and environmental persistence despite low reactivity in use.
How does Dimethicone/Bis-lsobutyl PPG-20 Crosspolymer work chemically?
The molecule is a crosslinked organosilicon-polyether elastomer network with bulky alkyl substitution, which helps swell oils and create a soft-focus, powdery feel. It is typically supplied as a dispersion or gel and is stable across normal cosmetic pH ranges, with performance driven more by oil compatibility and shear processing than by acid-base chemistry.
