SUCROSE POLYSTEARATE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sucrose Polystearate is a versatile sucrose ester, predominantly functioning as an emulsifier and stabilizer to achieve uniform and pleasant product textures. It simultaneously acts as a mild emollient, delivering gentle hydration and enhancing the skin's sensory experience, making it highly compatible with all skin types.

Summary

Emulsifying Emollient Stabilizing Cleansing Agent Sensory Enhancer

Science

Mechanism of Action

This ingredient operates on multiple levels: it effectively combines immiscible oil and water phases as an emulsifier, stabilizing product formulations to maintain a smooth, homogeneous consistency. On the skin, it forms a light, protective barrier, functioning as an emollient to minimize trans-epidermal water loss, resulting in a soft and silky feel. It also contributes to gentle cleansing by aiding in the removal of surface impurities and significantly improves the overall sensory impact of a cosmetic product, enhancing spreadability and reducing greasiness in richer formulations.

Stability

Sucrose Polystearate demonstrates optimal stability within a pH range of 4 to 8. Exposure to pH levels exceeding 8 may lead to saponification of the ester bond, while very low pH values can cause acid aggregation, compromising formulation integrity. It is soluble in oil and can be dispersed effectively in hot water, making it suitable for cold process formulations.

Synergies

  • Enhances the stability and longevity of co-formulated ingredients
  • Contributes to reducing the perceived greasiness in richer formulations

Conflicts

  • Flocculation in high electrolyte concentrations
  • Degradation via saponification at pH values above 8
  • Instability due to acid aggregation at low pH values
