MYRISTYL GLYCOL.

Valuable CAS 21129-09-9 / HAIR CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - FOAM BOOSTING, VISCOSITY CONTROLLING

Myristyl Glycol is a versatile nonionic ingredient functioning as an emulsifier, rheology modifier, and emollient. It improves product texture and stability by blending oil and water phases while providing a soft, smooth feel to the skin.

Summary

Emulsifying Surfactant Conditioning Emollient Thickener Rheology Modifier

Science

Mechanism of Action

Myristyl Glycol, also known as Ceteareth-60 Myristyl Glycol, operates as a nonionic surfactant, emulsifier, and conditioning agent. It reduces surface tension, enabling the stable blending of disparate oil and water components within formulations. Concurrently, it acts as an emollient, delivering skin-softening benefits, and a rheology modifier, effectively thickening products without compromising foam properties.

Stability

Exhibits robust hydrolytic and thermal stability across a broad pH range of 2-12. Optimal incorporation into formulations occurs when heated above its melting point (70-80°C). It is compatible with elevated electrolyte levels, including salt, and performs well in sulfate-free systems. Formulation temperatures should not exceed 80°C.

Synergies

  • Enhances viscosity synergistically with salt in surfactant systems.
