QUATERNIUM-71.

Valuable CAS 93762-18-6 / ANTISTATIC

A synthetic, highly ionized polymer, QUATERNIUM-71 functions as an exceptional humectant. Its hygroscopic nature enables it to intensely hydrate the skin, simultaneously forming a protective barrier against moisture loss.

Science

Mechanism of Action

QUATERNIUM-71, also known as Polyquaternium-71, is a water-soluble polymer with a strong affinity for water molecules. It binds atmospheric moisture to the skin, delivering profound hydration. Furthermore, it creates a humidity-protective gradient on the skin's surface, significantly reducing transepidermal water evaporation and thus maintaining optimal moisture levels.

Sensitization risk Low

While formal CIR, SCCS, or FDA safety assessments for QUATERNIUM-71 are currently unavailable, it is described as safe, hypoallergenic, and non-irritating, including for the eyes. It does not cause a tacky sensation, clog pores, stain, or impede normal skin respiration. Concerns occasionally associated with other quaternary ammonium compounds (QACs) regarding skin irritation or sensitization are not specifically attributed to QUATERNIUM-71.
