Science
Mechanism of Action
This ingredient operates as an amphoteric surfactant, meaning it possesses both hydrophilic (water-loving) and hydrophobic (oil-loving) properties. This unique amphiphilic structure allows it to form micelles, which are spherical structures that effectively trap and suspend impurities like dirt and excess sebum. These micelles can then be easily rinsed away, leaving the skin clean. Additionally, its surfactant properties contribute to foam generation and the stabilization of oil and water mixtures within a product.

Dusting Analysis
As a primary surfactant, this ingredient is typically used at functional concentrations rather than in trace amounts for 'dusting' purposes.
The Formula
Formulation
Stability
This ingredient is a biodegradable wetting agent and coupler that maintains stability across a wide pH range, performing effectively in both highly alkaline and acidic systems. It demonstrates high tolerance for inorganic salts and can be directly incorporated into aqueous alkaline systems, remaining soluble in up to 35% caustic soda.
Safety
Safety Profile
While generally considered safe for use in cosmetic products, the Cosmetic Ingredient Review (CIR) has not conducted a direct review of Sodium Capryloamphohydroxypropylsulfonate. However, related fatty amphocarboxylates and similar amphoteric surfactants have been evaluated by CIR and deemed safe. Data regarding its topical application during pregnancy are currently insufficient, advising consultation with a healthcare professional. Potential, though uncommon, side effects include mild skin irritation, allergic reactions, dryness, or redness; a patch test is recommended before widespread use.
