Valuable CAS 61788-49-6 / HAIR CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SKIN CONDITIONING - OCCLUSIVE

A precision derivative of lanolin alcohol, this highly effective emollient and skin conditioner is engineered to enhance skin smoothness and moisture retention. Its modified structure improves spreadability and reduces tackiness compared to traditional lanolin.

Summary

emollient emulsifying skin conditioning hair conditioning

Science

Mechanism of Action

It functions as an occlusive emollient, forming a water-resistant lipid film to prevent transepidermal water loss (TEWL) and trap existing moisture. Acetylation removes polar hydroxyl groups, rendering it more hydrophobic, which enhances skin 'slip' and stability.

Stability

Highly stable due to its non-drying, saturated hydrocarbon nature, resisting autoxidation and rancidity. It has a melting point of approximately 38-44°C.

Conflicts

  • Strong oxidizing agents
  • May destabilize certain O/W emulsions due to high hydrophobicity
