SUCROSE LAURATE.

Valuable CAS 25339-99-5 / 37266-93-6 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sucrose Laurate is an amphiphilic, non-ionic surfactant and emulsifier derived from sucrose and lauric acid. It offers multifaceted benefits, including enhancing skin hydration, facilitating the penetration of other active ingredients, and acting as a gentle conditioning agent, making it suitable for diverse precision skincare applications.

Summary

emollient emulsifying skin conditioning surfactant

Science

Mechanism of Action

This ingredient operates by effectively reducing the surface tension between immiscible liquid phases, such as oil and water, thereby enabling the creation of stable emulsions. On the skin, it functions as a conditioning agent and emollient, promoting a soft and smooth texture, while also delivering moisturizing properties. Notably, Sucrose Laurate can transiently alter the stratum corneum barrier, which enhances the permeation of other compounds. In cleansing formulations, its surfactant properties aid in the efficient removal of fat and soil particles.

Key findings

  1. 01 Demonstrated a significant increase in the penetration of 4-hydroxybenzoic acid (4-HB) into human stratum corneum, suggesting a temporary modification of skin barrier integrity.
  2. 02 Application of a Sucrose Laurate-based cleanser resulted in skin that was twice as hydrated 2 hours after use, when compared to a moisturizing Sodium Laureth Sulfate cleanser.
  3. 03 In rabbit studies, application led to a substantial increase in skin biopsy thickness, indicating a potential effect on skin structure. However, this concentration range also showed some irritation potential in dermal exposure studies.

Stability

Sucrose Laurate achieves maximum stability at a pH range of 4 to 5, where hydrolysis is approximately 6.7% after 20 hours at 100°C. Its amphiphilic nature supports the solubilization of poorly water-soluble compounds and the dispersion of essential oils. It is compatible with acidic pH, making it suitable for exfoliating products. However, it can be prone to hydrolytic instability during prolonged storage, potentially leading to increased crystallinity.

Synergies

  • Acidic pH environments (e.g., in formulations with AHAs/PHAs)
  • Essential oils and fragrances (for enhanced dispersion and solubilization)
  • Poorly water-soluble drugs (for improved solubility)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that saccharide esters, including Sucrose Laurate, are safe for use in cosmetics at present practices and concentrations. While dermal exposure studies in test animals showed some irritation potential at 5-15% concentrations, an unknown concentration in a hydrogel was non-irritating. A 10% solution instilled into rabbit eyes did exceed a mild irritation threshold (MDES of 21, threshold 20). Overall, in typical cosmetic applications, it is considered to have a low irritancy profile.
