Cetearyl alcohol is a non-drying, high-molecular-weight alcohol derived from natural wax sources. It acts as an emollient and thickening agent in lotions and creams, helping to create stable emulsions and improve texture. It forms a protective barrier on skin, reducing transepidermal water loss without leaving a greasy feel.
Benefits
- Strengthens skin barrier and reduces moisture evaporation
- Creates smooth, creamy texture in formulations
- Non-irritating and generally well-tolerated
- Aids emulsion stability and product consistency
- Leaves skin soft without occlusive heaviness
Who it suits
- All skin types, especially dry and sensitive
- Barrier-compromised skin
- Those seeking lightweight hydration
