In plain English

PEG-150 Laurate is a man-made ingredient that helps cleansers feel thick and creamy. It also helps oil and water mix together so the product stays smooth. Despite being a surfactant (a cleansing agent), it is very mild and unlikely to dry out your skin or cause irritation.

How reviews are scored

Quick decision guide

Useful, but context matters

PEG-150 Laurate 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.

Step 1Start with the score, then check the irritation and clogging risk before judging PEG-150 Laurate.
Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
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-150 Laurate is a polyethylene glycol (PEG) compound combined with lauric acid, a fatty acid found in coconut oil. The '150' refers to the average number of ethylene glycol units, which makes it a large, water-soluble molecule that acts as a thickener and mild cleansing agent.

How it works

In a cosmetic formula, PEG-150 Laurate increases the viscosity (thickness) of water-based products, giving them a luxurious, gel-like feel. It also helps stabilize emulsions (mixtures of oil and water) and can boost foam in cleansers without being harsh on the skin barrier.

Pros

Gentle on skin

Unlike many surfactants, PEG-150 Laurate is very mild and unlikely to cause dryness, tightness, or irritation, making it suitable for sensitive skin.

Improves product texture

It gives cleansers a rich, creamy feel and stable foam, which enhances the sensory experience without adding heavy oils.

Cons and cautions

Synthetic origin

It is a petroleum-derived ingredient, which may not appeal to those seeking natural or plant-based skincare.

Potential manufacturing impurities

PEG compounds can contain trace levels of ethylene oxide or 1,4-dioxane if not properly purified, though reputable brands use high-quality grades.

Best for

People with normal to dry skin who want a gentle, non-stripping cleanser
Anyone looking for a creamy, foaming wash without harsh sulfates

Use caution if

Those who prefer 100% natural or plant-derived thickeners only
Individuals with known sensitivity to PEG compounds (rare)

Usage tips

Use in rinse-off products like cleansers and shampoos rather than leave-on products to minimize any potential irritation.

Pair with other mild surfactants (e.g., coco-glucoside) for an extra-gentle cleansing experience.

Safety summary

PEG-150 Laurate is considered safe for use in cosmetics at typical concentrations. The main concern is the potential for contamination with ethylene oxide or 1,4-dioxane during manufacturing, but reputable suppliers use purification processes to minimize these impurities. Overall, it has a low irritation and comedogenic risk.

Research notes

The Cosmetic Ingredient Review (CIR) has evaluated PEG compounds and concluded they are safe for use in cosmetics when formulated to be non-irritating. Studies show PEG-150 Laurate has low acute toxicity and is not a significant skin sensitizer. No recent peer-reviewed studies specifically on PEG-150 Laurate were found, but the broader PEG family is well-studied.

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 as used in cosmetics when properly manufactured.
Common uses: Cleansers, Shampoos, Body washes, Lotions
Environmental note: PEG-150 Laurate is not readily biodegradable in all conditions, which is a consideration for eco-conscious consumers. Some manufacturers are working on more sustainable alternatives.

Good to know

The '150' in the name refers to the polymer chain length, which affects how thick the ingredient makes a formula.
PEG-150 Laurate is often used in 'sulfate-free' cleansers to provide foam without harsh detergents.
