emulsifying preservative surfactant/cleansing antimicrobial antifungal delivery enhancer

Science

Mechanism of Action

As a surfactant, Sodium Caprylate reduces surface tension, enhancing the cleansing ability of formulations for skin and hair. It functions as an emulsifier, critical for creating stable mixtures of oil and water in cosmetic products. Beyond its formulation roles, it acts as an antimicrobial agent and preservative, contributing to product longevity and potentially aiding in the transdermal delivery of other active ingredients.

Dusting Analysis

Not commonly dusted

Sodium Caprylate's primary roles are foundational to product formulation and stability (e.g., surfactant, emulsifier, preservative) rather than acting as a 'hero' active ingredient that might be used at concentrations insufficient for its claimed effects. Its functions are integral to a product's overall integrity and performance, making 'dusting' an unlikely concern.

A 1% solution typically maintains a pH between 7 and 9, while a more concentrated 2.5g in 25mL solution exhibits a pH range of 8.0 to 10.5, indicating stability within an alkaline environment.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded Sodium Caprylate is safe for use in cosmetics when formulated to be non-irritating and non-sensitizing. Its safety is further supported by FDA affirmation as an approved food additive in the US and EU. While the raw ingredient in high concentrations can be irritating, cosmetic formulations typically incorporate it at levels that exhibit low irritancy.
