CALCIUM BEHENATE.

Valuable CAS 3578-72-1 / ANTICAKING, OPACIFYING, VISCOSITY CONTROLLING

A high-performance metallic soap and lipid-structuring agent that serves as a stabilizing backbone for anhydrous formulations. By creating a sophisticated crystalline network, it ensures the controlled release of oil-soluble actives while simultaneously delivering essential calcium ions to support the skin's structural integrity.

Science

Mechanism of Action

Calcium Behenate functions by establishing a rigid lipid matrix that increases the viscosity of oil phases and prevents the sedimentation of pigments or mineral filters. Biologically, it provides exogenous calcium to the stratum corneum—a critical signaling molecule that triggers keratinocyte differentiation (via KRT1 and KRT14 expression) and accelerates skin barrier repair.

Key findings

  1. 01 Demonstrated up-regulation of genes associated with cell differentiation and skin matrix synthesis when applied at 2.25% in barrier-repair formulations.
  2. 02 Proven efficacy as a stabilizing lubricant and gelling agent in pharmaceutical delivery systems at concentrations between 0.1% and 10%.
  3. 03 Identified as a synergistic agent that enhances antimicrobial preservation and texture stability in water-free balms at levels as low as 0.01%.

While often used for texture at low levels, its primary biological benefits for skin barrier gene expression require a concentration of at least 2.25%. Formulations using it strictly as an opacifier below 0.1% are not leveraging its therapeutic potential.

Stability

Highly stable in anhydrous (water-free) environments; however, it is sensitive to low pH environments which can cause the molecule to revert to behenic acid.
