Science
Mechanism of Action
As an anionic surfactant, SODIUM C13-17 ALKANE SULFONATE functions by significantly decreasing the surface tension at the interface of immiscible liquids. This action facilitates the formation of stable emulsions and allows for effective mixing. It forms micelles, which are molecular aggregates that encapsulate lipophilic (oil-soluble) impurities, enabling their suspension and removal in aqueous solutions, thereby acting as a potent cleansing agent.

Dusting Analysis
This ingredient is hygroscopic, meaning it readily absorbs moisture from the air. In high concentrations within powder formulations, this property can lead to deliquescence and subsequent clumping, rather than dusting issues commonly associated with fine powders.
The Formula

Stability
The ingredient demonstrates excellent stability across a broad pH range, including highly acidic, alkaline, and neutral environments. It also maintains its performance effectively in hard water conditions.

Safety
Safety Profile
While not specifically reviewed by CIR, a related ingredient, Sodium α-Olefin Sulfonates, was deemed safe for rinse-off products and up to 2% in leave-on products with controlled impurity levels. However, SODIUM C13-17 ALKANE SULFONATE is classified as a Category 2 skin irritant, indicating it 'Causes skin irritation,' and a Category 1 serious eye damage agent, meaning it 'Causes serious eye damage.' No specific SCCS or FDA cosmetic status is available.

Verdict
Despite its efficacy as a versatile cleansing and foaming agent, the classification of SODIUM C13-17 ALKANE SULFONATE as a Category 2 skin irritant and Category 1 serious eye damage agent warrants significant caution for its inclusion in precision skincare formulations.
