Question 1

What does Bis-Isobutyl PPG-20 Crosspolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic texture and rheology modifier used to thicken, gel, and stabilize oil-rich or anhydrous formulas. It can also improve slip, cushion, and film feel in makeup, sunscreen, and skin-care products.

Question 2

Is Bis-Isobutyl PPG-20 Crosspolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient has friction because it is a synthetic crosslinked polymer rather than a simple biodegradable cosmetic material. It is generally used for sensorial and structural performance, but some standards scrutinize it under synthetic polymer or microplastic-related policies depending on particle form and solubility.

Question 3

Is Bis-Isobutyl PPG-20 Crosspolymer sustainable?

Accepted Answer

This material is petrochemical-derived and is not expected to be readily biodegradable. Its sustainability profile is mainly limited by persistence concerns and end-of-life uncertainty rather than by land-use or agricultural sourcing issues.

Question 4

Is Bis-Isobutyl PPG-20 Crosspolymer COSMOS-approved?

Accepted Answer

This ingredient is not aligned with COSMOS-natural or COSMOS-organic principles because it is a synthetic crosslinked polymer. From a Green Chemistry view, it has drawbacks around fossil feedstock use and limited biodegradability, even though it may be effective at low use levels for formula structure.

Question 5

How does Bis-Isobutyl PPG-20 Crosspolymer work chemically?

Accepted Answer

The molecule is a hydrophobic, crosslinked polyether network based on propylene oxide repeat units with branched alkyl modification, which gives it oil compatibility and gel-forming behavior. It is typically used as a low-level rheology modifier or sensory polymer in nonaqueous or oil-phase systems, with performance influenced by oil polarity, shear, and heating during dispersion.
