Question 1

What does Lauryl Dimethicone/Polyglycerin-3 Crosspolymer do in a cosmetic formula?

Accepted Answer

This ingredient functions mainly as a polymeric emulsifier, stabilizer, and texture modifier. It helps suspend water in oil-rich systems while giving creams, sunscreens, and makeup a smooth, cushioned feel.

Question 2

Is Lauryl Dimethicone/Polyglycerin-3 Crosspolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is usually flagged because it is a synthetic organosilicon polymer rather than a biodegradable botanical or mineral material. It is generally low-irritation on skin, but some clean frameworks screen out this chemistry due to persistence and possible trace cyclic manufacturing residues.

Question 3

Is Lauryl Dimethicone/Polyglycerin-3 Crosspolymer sustainable?

Accepted Answer

This material is synthetically made from mineral-derived and petrochemical feedstocks, not renewable plant sourcing. It is expected to be poorly biodegradable and environmentally persistent compared with simpler fatty alcohols, sugars, or plant oils.

Question 4

Is Lauryl Dimethicone/Polyglycerin-3 Crosspolymer COSMOS-approved?

Accepted Answer

This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards because synthetic organosilicon polymers fall outside the allowed ingredient categories. Its Green Chemistry alignment is limited due to nonrenewable inputs, complex synthesis, and low biodegradability.

Question 5

How does Lauryl Dimethicone/Polyglycerin-3 Crosspolymer work chemically?

Accepted Answer

This compound is an amphiphilic crosslinked polymer with oil-compatible alkyl and organosilicon segments plus hydrophilic polyglycerin groups, which is why it can sit at oil-water interfaces and stabilize emulsions. It is typically used at low levels as a rheology and emulsification aid, is broadly pH-stable in finished products, and is not prone to oxidation like unsaturated plant oils.
