SODIUM LAURATE/LINOLEATE/OLEATE/PALMITATE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SKIN PROTECTING

A complex blend of sodium salts derived from lauric, linoleic, oleic, and palmitic fatty acids, this ingredient functions primarily as a versatile skin conditioning agent. It contributes to both the cleansing efficacy of wash-off products and the emollient properties in leave-on formulations, helping to soften and protect the skin barrier.

Science

Mechanism of Action

This ingredient operates as a multi-functional agent within cosmetic formulations. As a blend of fatty acid sodium salts, it inherently acts as a surfactant, effectively reducing surface tension to allow for the mixing of oil and water, which is critical for cleansing and the formation of rich lather. Beyond its surfactant capabilities, it provides emollient benefits, smoothing and softening the skin's surface. It also functions as a skin conditioning agent, supporting overall skin health, and offers a degree of skin protection against environmental factors. Additionally, its constituent salts contribute to the emulsifying process and can modulate product viscosity.

The CIR Expert Panel considers the fatty acid components of this blend (including Oleic, Lauric, Palmitic acids) safe for cosmetic use, provided the final formulation is non-irritating and non-sensitizing. Certain components, like Sodium Oleate and Sodium Palmitate, are also recognized as generally safe (GRAS) by the US FDA for food use. However, its 'medium' irritancy rating suggests careful formulation is required to mitigate potential skin reactions, particularly at higher concentrations.
