What is Arachidyl Alcohol?

Arachidyl alcohol is a saturated fatty alcohol containing 20 carbon atoms, typically sourced from vegetable oils like peanut or rapeseed, or produced synthetically for purity. In cosmetics, it belongs to the emollient and surfactant category, commonly found in creams, lotions, and conditioners. It functions by forming a structured interfacial film around oil droplets in emulsions, preventing separation and enhancing product stability. As a thickener, it increases viscosity to improve texture and spreadability, making formulations easier to apply. Its emollient properties help mimic the skin's natural lipids, promoting a smoother surface feel and aiding in moisture retention when combined with other ingredients. This multifunctional role supports diverse product types, from moisturizers to hair care, without introducing harshness.

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.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Benefits

- Helps maintain emulsion stability for longer-lasting product performance.

- Adjusts formula thickness for better texture and application.

- Softens skin feel by improving slip and reducing surface roughness.
