Case Study

Sodium Cocoamphoacetate Surfactant Used in Mild Cleansing Combination Formulation

Sikora, Elżbieta, et al. International Journal of Cosmetic Science, 2015, 37(6), 574-578.

This work developed a mild cleansing composition containing supercritical CO2 extract of strawberry seeds (SC-CO2 strawberry seed oil) as a moisturizing and softening agent for the skin. Experiments showed that the oil concentration in this formulation affected the stability of the product. Only the formulation containing 0.5-2% of the extract showed high stability.
Washing formulation composition and preparation
· Sodium cocoamphoacetate and disodium lauryl sulfosuccinate were included as gentle surfactants in this new cleansing formula. A small amount of sodium lauryl sulfate served as the primary detergent, while cocamide DEA and cocamidopropyl betaine acted as secondary surfactants. SC-CO2 strawberry seed oil was incorporated for its moisturizing and active properties. The components were added in a specific order to ensure a uniform product: first, the oil was blended with glycerin and surfactants, followed by gradual addition of water.
· Stability tests indicated that oil concentration significantly affected the product's stability; only samples with 2% or less oil (C 0% St, C 0.5% St, C 1% St, C 2% St) remained stable. These formulations were all homogeneous, clear, colorless, pleasant-smelling liquids with no signs of instability. In contrast, samples containing more than 2% oil developed a visible layer on the surface one week after preparation.
