QUATERNIUM-18 BENTONITE.

Valuable CAS 68953-58-2 / 1340-69-8 / VISCOSITY CONTROLLING

Quaternium-18 Bentonite is an organo-modified clay compound primarily utilized for its formulation-stabilizing properties. It effectively suspends solid particles and emulsifies oil and water components, contributing to optimal product texture while offering therapeutic benefits for irritated or dermatitis-prone skin.

Viscosity Controlling Suspending Agent Emulsifier Absorbent Conditioning Agent Emulsion Stabilizer

Science

Mechanism of Action

This ingredient functions as a non-surfactant suspending agent, viscosity-controlling agent, and emulsifier within cosmetic formulations. Its unique modified clay structure enables it to evenly distribute insoluble ingredients and prevent the separation of oil and liquid phases. The bentonite component provides absorbent qualities, while the quaternary ammonium modification imparts conditioning properties and aids in emulsion stabilization, exhibiting thixotropic behavior for smooth application.

Key findings

  1. 01 A quaternium-18 bentonite lotion was effective in preventing or diminishing experimentally produced poison ivy and poison oak allergic contact dermatitis. Reactions on treated sites consistently appeared later and were reduced compared to untreated control sites.
  2. 02 A skin moisturizing cream containing Quaternium-18 Bentonite effectively improved chronic hand dermatitis.
  3. 03 Bentonite (a component of Quaternium-18 Bentonite) was effective in the improvement of diaper dermatitis and had faster effects compared to Calendula.
