POLYQUATERNIUM-31.

Insufficient Data CAS 136505-02-7 / 189767-67-7 / ANTISTATIC, FILM FORMING

POLYQUATERNIUM-31 is a synthetic cationic polymer engineered to adhere to negatively charged biological surfaces, such as skin and hair. It functions primarily as an antistatic and film-forming agent, contributing to surface conditioning and moisture retention by creating a protective, continuous film.

Summary

Antistatic Film forming

Science

Mechanism of Action

As a cationic polymer, POLYQUATERNIUM-31 electrostatically binds to the naturally negatively charged surfaces of skin and hair. This adhesion enables it to neutralize static charges, acting as an effective antistatic agent. Concurrently, it forms a cohesive, continuous film over these surfaces. This film provides a conditioning effect and can enhance skin hydration by mitigating transepidermal water loss.

Stability

Cationic polyquaterniums, including POLYQUATERNIUM-31, may complex with anionic surfactants if formulations are not optimized, potentially leading to undesirable film deposition or product instability. Polymers with higher molecular weight and increased positive charge tend to exhibit a greater propensity for build-up.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

While specific CIR assessment data for POLYQUATERNIUM-31 is currently insufficient, the CIR Expert Panel has generally deemed other Polyquaterniums safe for cosmetic applications. Independent assessments indicate low concerns for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity.

Verdict

Insufficient Data

POLYQUATERNIUM-31 acts as a film-former and antistatic agent with low irritancy, but current data is insufficient to establish its specific efficacy or optimal use in precision skincare formulations.
