QUATERNIUM-30.

Valuable CAS 50978-31-9 / 58748-40-6 / ANTISTATIC, HAIR CONDITIONING

Polyquaternium-30 is a cationic polymer known for forming a lightweight, continuous film on the skin. This film helps to reduce transepidermal water loss (TEWL), thereby enhancing skin hydration and contributing to a smooth, silky feel.

Summary

Antistatic Film-forming

Science

Mechanism of Action

As a positively charged cationic polymer, Polyquaternium-30 adsorbs onto negatively charged skin surfaces, forming a protective, imperceptible film. This film actively minimizes transepidermal water loss, directly supporting improved skin hydration. In addition to its hydrating film-forming capabilities, it also functions as an antistatic agent on the skin.
