Decyl Glucoside

Cleansing

What is Decyl Glucoside?

Decyl glucoside is a non-ionic surfactant from the alkyl polyglucoside group, created by combining glucose—sourced from corn starch or wheat—and decyl alcohol from coconut or palm kernel oils. This plant-based compound excels in mild personal care formulations like shampoos, body washes, facial cleansers, and baby products. It functions by decreasing water's surface tension, which allows micelles to form and trap oils, dirt, and residues for easy rinsing. It also generates soft, abundant foam and reinforces emulsion structures by fortifying the interface between water and oil phases, preventing separation in creams and lotions. Its compatibility with skin arises from a structure similar to natural glycosides, supporting barrier integrity during cleansing.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Surfactant

Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.

Cleansing agent

Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.

Emulsion stabilizer

Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.

Benefits

Offers thorough cleansing by lifting impurities without harshness

Builds creamy, stable lather for pleasant application

Supports emulsion integrity in lotions and cleansers
