PEG-20 Hydrogenated Lanolin

What is PEG-20 Hydrogenated Lanolin?

PEG-20 Hydrogenated Lanolin derives from lanolin, a wax secreted by sheep wool glands. Hydrogenation saturates its lipid chains for better stability, while ethoxylation adds 20 polyethylene glycol units, enhancing water solubility. This nonionic compound appears in shampoos, conditioners, lotions, and creams. It functions by reducing interfacial tension as a surfactant, enabling oil-water mixing for uniform emulsions. As an emollient, it deposits a lubricious film on skin and hair cuticles, minimizing friction and improving tactile qualities. Its amphiphilic structure supports solubilization of lipophilic actives, contributing to formula clarity and efficacy without heavy residue.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Hair conditioning

Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.

Surfactant

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

Emulsifying agent

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

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

Softens skin and hair by forming a smoothing barrier that reduces friction.

Stabilizes emulsions for consistent lotion and cream textures.

Enhances hair conditioning, boosting shine and ease of combing.

Who It's For
