C30-50 Alcohols

What is C30-50 Alcohols?

C30-50 Alcohols consist of a mixture of saturated fatty alcohols with carbon chain lengths ranging from 30 to 50, often sourced from plant-derived fats like coconut or palm kernel oil through hydrogenation processes. These high-molecular-weight compounds appear as waxy solids at room temperature and find common use in oil-in-water emulsions such as creams, lotions, and conditioners. In formulations, they function by aligning at oil-water interfaces to form a protective film that prevents droplet merging, while their crystalline structure creates a three-dimensional network throughout the product, enhancing thickness and preventing separation. This dual action ensures smooth texture, even application, and long-term stability without greasiness.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Stabilising
Improves physical and/or chemical stability (e.g., preventing separation, precipitation, or degradation) to keep performance consistent over shelf life.

Benefits

Provides a smooth, non-greasy feel to creams and lotions.

Helps maintain product consistency over time.

Supports skin's surface softness and flexibility.

Who It's For
