Science
Mechanism of Action
As a surfactant, LAURETH-16 reduces the surface tension of cosmetic formulations, which facilitates uniform product spreading and enhances cleansing efficacy. Concurrently, its emulsifying properties promote the formation of stable mixtures between immiscible liquids, such as oil and water, contributing to product homogeneity. It also acts as an effective foam booster in cleansing products.

Stability
LAURETH-16 exhibits robust stability across a broad spectrum of environmental conditions, maintaining its activity regardless of the presence of oxidizing or reducing agents, hard water, cold temperatures, or a wide pH range spanning from acidic to diluted alkaline solutions.
Safety
Safety Profile
The CIR Expert Panel has concluded that Laureth ingredients, including LAURETH-16, are safe for use in cosmetic products when specifically formulated to be non-irritating. Studies on developmental, reproductive toxicity, and mutagenicity have yielded negative results for these compounds. However, these compounds possess the potential to irritate the skin, necessitating careful formulation. Trace amounts of 1,4-dioxane, a byproduct of the ethoxylation process, may be present but are controlled through rigorous purification steps.
