PEG-45 Palm Kernel Glycerides

PEG / Ethoxylated

What is PEG-45 Palm Kernel Glycerides?

PEG-45 Palm Kernel Glycerides is a synthetic ingredient produced by ethoxylating glycerides derived from palm kernel oil, sourced from the seeds of the oil palm tree (Elaeis guineensis). This process attaches 45 units of polyethylene glycol to the fatty acid esters of glycerol, creating a water-soluble compound. Commonly found in hair conditioners, shampoos, lotions, and cleansing products, it functions by reducing surface tension for better spreading and mixing. The hydrophilic PEG chain allows it to solubilize oils into water-based formulas, form stable emulsions between immiscible phases, and provide a smooth, lubricious feel on skin and hair. Its amphiphilic nature bridges oil and water, contributing to creamy consistencies and rinse-off efficacy in wash-off items.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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.
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.

Benefits

Supports smoother application by softening skin surfaces and improving slip.

Aids in creating stable blends of oils and water for even product textures.

Facilitates gentle cleansing through surface tension reduction.

Who It's For

Who May Benefit Who Should Avoid
People with dry skin seeking added softness from emollient effects.
Those preferring to limit PEG ingredients due to potential impurities.
Individuals using emulsified lotions or creams for consistent formulas.
People with sensitivity to ethoxylated compounds.
Users of shampoos or body washes needing effective yet mild surfactants.
Individuals concerned about palm-derived materials.
