SUCROSE DISTEARATE.

Valuable CAS 27195-16-0 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sucrose Distearate is a versatile sucrose ester, predominantly functioning as an emulsifier to stabilize oil-in-water formulations. It also acts as an emollient and moisturizer, enhancing skin hydration, softness, and smoothness while contributing to a lighter skin feel.

Summary

Emulsifying Skin-conditioning Emollient Surfactant Moisturizing Cleansing Smoothing

Science

Mechanism of Action

This ingredient primarily stabilizes oil-in-water emulsions, ensuring uniform blending of immiscible phases. On the skin, it forms a lightweight moisture barrier, which helps to reduce transepidermal water loss and maintain hydration. Research indicates it can form a multilamellar liquid crystalline network, directly supporting skin moisturization. Furthermore, it contributes to skin conditioning, offering gentle cleansing properties as a mild surfactant.

Stability

Sucrose Distearate maintains stability within a pH range of 4 to 8. Formulations exceeding pH 8 may experience saponification of the ester bond, while highly acidic conditions (low pH) can lead to acid aggregation and flocculation. The ingredient tolerates heating up to 160°C, though slight discoloration may occur above 120°C due to potential caramelization of trace sucrose.

Synergies

  • Often combined with other sucrose stearates (e.g., sucrose monostearate) to optimize emulsification and skin-conditioning benefits.

Conflicts

  • High pH (above 8)
  • Low pH (acidic media)
  • Higher electrolyte environments
