Triarachidin

What is Triarachidin?

Triarachidin consists of glycerol esterified with three molecules of arachidic acid, a long-chain saturated fatty acid sourced from plant oils like peanut and rapeseed. This waxy lipid serves primarily in lip products, ointments, and emulsion-based skincare such as creams and lotions. Its structure enables emollient action by depositing a thin film that reduces transepidermal water loss and enhances skin suppleness. In formulations, it modifies rheological properties to achieve optimal thickness, facilitating smooth dispensing and even application. Additionally, its amphiphilic nature supports emulsification, bridging oil and water phases to maintain product homogeneity over time. This multifunctional ingredient improves overall user experience through better texture and stability without introducing notable risks.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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.
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.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Softens and smooths skin surface for improved feel.

Adjusts product thickness for better spreadability and stability.

Aids in blending oils and water for consistent emulsions.
