BENTONITE.

Valuable CAS 1302-78-9 / ABSORBENT, BULKING, EMULSION STABILISING, VISCOSITY CONTROLLING

A powerful volcanic clay prized for its high cation-exchange capacity, allowing it to act as a molecular magnet for skin impurities. It is a versatile mineral that provides both structural stability to formulations and intensive detoxification for the complexion.

Science

Bentonite utilizes a negative ionic charge to attract and encapsulate positively charged toxins, heavy metals, and excess sebum. Upon application, it creates a mechanical 'wicking' effect that draws out deep-seated debris and subcutaneous fluids, while its crystalline structure provides a temporary skin-toning and tightening sensation during the drying phase.

Key findings

  1. 01 Validated as non-sensitizing and non-irritating in HRIPT human clinical trials for mask applications.
  2. 02 Showed significant 50% improvement in global scores for chronic hand dermatitis and reduced dependency on topical corticosteroids.
  3. 03 Clinical trials showed over 88% of inflammatory lesions began recovery within 6 hours of application in dermatitis cases.

Because Bentonite acts as a primary functional texture-modifier and adsorbent, it is typically used at significant concentrations (3-8%) to achieve the desired viscosity or clay-mask effect; levels below 0.5% suggest it is being used merely as a suspension aid rather than an active detoxifying agent.

Stability

Insoluble in both oil and water but swells into a colloidal gel in water. Functions as a 'Pickering' emulsifier by stabilizing oil-water interfaces physically.

Synergies

  • Humectants
  • Non-ionic surfactants
  • Zinc Oxide

Conflicts

  • Electrolytes
  • Cationic preservatives
  • High concentrations of Ethanol
  • Metal mixing tools (neutralizes ionic charge)

Our Assessment

Valuable

An exceptional mineral for sebum control and inflammatory skin conditions, though it requires specific pH conditions and non-metallic handling to maintain its ionic efficacy.
