PEG-5 Hydrogenated Corn Glycerides

INCI: PEG-5 Hydrogenated Corn Glycerides

A gentle, semi-synthetic emulsifier derived from corn glycerides that helps stabilize creams and lotions without common irritation.

beautyskincareemulsifier

In plain English

This ingredient is a helper molecule that allows water and oil to mix smoothly in your skincare products, creating a stable, creamy texture. It is made by attaching a small PEG chain to hydrogenated corn glycerides (a fat from corn oil). Because it is mild and non-irritating, it is often used in sensitive-skin formulas.

Quick decision guide

Useful, but context matters

PEG-5 Hydrogenated Corn Glycerides is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PEG-5 Hydrogenated Corn Glycerides.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

PEG-5 Hydrogenated Corn Glycerides is a semi-synthetic emulsifier created by reacting ethylene oxide (PEG) with hydrogenated corn glycerides. The '5' indicates the average number of PEG units, which gives it mild water-attracting properties while retaining the emollient feel of the corn-derived fat.

How it works

In a formula, this ingredient sits at the boundary between water and oil droplets, reducing surface tension so they blend into a stable emulsion. This prevents your lotion or cream from separating and gives it a smooth, even texture. It also leaves a light, non-greasy film on skin that helps lock in moisture.

Pros

Gentle on skin

PEG-5 Hydrogenated Corn Glycerides has a very low irritation risk, making it a safe choice for sensitive skin formulas that need a stable emulsion.

Improves product texture

It helps create a smooth, non-greasy feel in creams and lotions, so your moisturizer spreads easily and absorbs quickly without leaving a heavy residue.

Cons and cautions

Potential manufacturing impurities

Like all PEG compounds, if not properly purified, trace amounts of 1,4-dioxane (a possible carcinogen) can be present. Reputable brands test for purity, but it's a concern for some consumers.

Semi-synthetic nature

Because it is chemically modified, it may not appeal to those seeking entirely natural or unprocessed ingredients, even though the base comes from corn.

Best for

  • Anyone looking for a gentle, non-irritating moisturizer or cleanser
  • People with sensitive or reactive skin who tolerate mild emulsifiers well

Use caution if

  • Those who strictly avoid all PEG-derived ingredients due to personal preference or ethical sourcing concerns

Usage tips

Look for products that list this ingredient near the middle or end of the INCI list, as it is typically used at low concentrations (under 5%).
If you have very sensitive skin, patch test a new product containing this ingredient, though it is generally well-tolerated.

Safety summary

PEG-5 Hydrogenated Corn Glycerides is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for 1,4-dioxane contamination during manufacturing, but reputable suppliers and brands ensure thorough purification. It is non-irritating and non-comedogenic for most skin types.

Research notes

The Cosmetic Ingredient Review (CIR) has evaluated PEG compounds and found them safe for cosmetic use when formulated to minimize impurities. Specific studies on PEG-5 Hydrogenated Corn Glycerides are limited, but its chemical relatives are well-documented as mild emulsifiers. No significant adverse effects have been reported in clinical or consumer use.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed PEG compounds safe when properly formulated and free of harmful impurities.
Common uses
Moisturizers, Cleansers, Serums, Sunscreens
Environmental note
Derived from corn, a renewable resource. However, PEG production involves ethylene oxide, which is derived from fossil fuels. Overall environmental impact is moderate compared to fully synthetic alternatives.

Good to know

  • The 'PEG' part is a polyethylene glycol chain, which is water-soluble, while the hydrogenated corn glycerides are oil-soluble — this dual nature makes it an effective emulsifier.
  • Hydrogenation makes the corn glycerides more stable and less prone to oxidation, extending the shelf life of your skincare product.
