Question 1

What does POLQUATERNIUM-11 do in a cosmetic formula?

Accepted Answer

This ingredient is a cationic film-former and conditioning agent, mainly used in hair styling, shampoos, and conditioners for hold, slip, frizz control, and reduced static.

Question 2

Is POLQUATERNIUM-11 clean?

Accepted Answer

From a clean-beauty perspective, it has friction because it is a synthetic quaternary polymer rather than a simple biodegradable conditioner. It is generally well tolerated on skin and scalp at cosmetic use levels, but its category is often scrutinized for persistence and aquatic profile.

Question 3

Is POLQUATERNIUM-11 sustainable?

Accepted Answer

This material is typically petrochemical-derived and is not considered readily biodegradable. Its cationic charge helps it bind to hair and surfaces, which is useful in formulas but raises environmental persistence concerns after rinse-off use.

Question 4

Is POLQUATERNIUM-11 COSMOS-approved?

Accepted Answer

It is not aligned with COSMOS-natural or COSMOS-organic standards because it is a synthetic cationic polymer outside the permitted natural-origin ingredient framework. Its fit with Green Chemistry is weak due to nonrenewable feedstocks and limited biodegradability, despite effective performance at low use levels.

Question 5

How does POLQUATERNIUM-11 work chemically?

Accepted Answer

This compound is a positively charged copolymer built from vinylpyrrolidone and quaternized dimethylaminoethyl methacrylate units, giving it strong substantivity to negatively charged hair fibers. It is commonly used around 0.1% to 5% depending on whether the goal is light conditioning, styling hold, or deposition support, and it is generally compatible with water-based systems across typical personal-care pH ranges.
