Science
Mechanism of Action
This anionic surfactant operates by lowering the surface tension between components in a formulation, such as oil and water. Its molecular design includes both hydrophilic and hydrophobic ends, enabling it to attract and encapsulate dirt, excess sebum, and other impurities, allowing for their easy removal with water. It also functions as an emulsifying agent, promoting product stability by preventing phase separation and ensuring uniform ingredient distribution, in addition to acting as a foaming agent.

Stability
Sodium Laureth-13 Carboxylate exhibits excellent thermal and chemical stability. Its foam stability remains largely independent of the formulation's pH, offering significant flexibility for products with varying pH levels. It is compatible with both alkaline and acidic ingredients, as well as electrolytes.
Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated Sodium Laureth-13 Carboxylate, it has assessed related ingredients like Sodium Laureth Sulfate as safe in cosmetics when formulated to be non-irritating. EWG Skin Deep indicates low concerns for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity. However, it highlights high concerns regarding potential contamination from toxic impurities, likely associated with the ethoxylation manufacturing process.
