Question 1

What does Acrylates/C10-30 do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic thickener, gel former, and emulsion stabilizer used to build viscosity and suspend droplets or particles in creams, gels, cleansers, and sunscreens.

Question 2

Is Acrylates/C10-30 clean?

Accepted Answer

From a clean-beauty perspective, it is often flagged because it is a persistent synthetic polymer rather than because of typical skin-sensitivity concerns. It is generally well tolerated on skin at cosmetic use levels, but some standards scrutinize residual monomers and polymer persistence.

Question 3

Is Acrylates/C10-30 sustainable?

Accepted Answer

This material is typically petrochemical-derived and is not considered readily biodegradable. Its main sustainability issue is environmental persistence, especially as regulations and retailer standards continue to tighten around synthetic polymer particles and residues.

Question 4

Is Acrylates/C10-30 COSMOS-approved?

Accepted Answer

It is not aligned with COSMOS organic or natural formulations, where synthetic, non-biodegradable polymers are generally not permitted. From a Green Chemistry lens, its low use level is efficient, but its fossil feedstock origin and limited biodegradability are clear drawbacks.

Question 5

How does Acrylates/C10-30 work chemically?

Accepted Answer

The molecule is a high-molecular-weight, lightly crosslinked polymer with hydrophilic acid groups and long hydrophobic side chains, which lets it swell in water and help stabilize oil-in-water systems. It is commonly used around 0.1% to 1.0%, thickens best after neutralization in the mildly acidic to neutral range, and can lose viscosity in high-electrolyte systems or with incompatible cationic ingredients.
