Ingredient review
PEG-30 Hydrogenated Castor Oil Laurate
INCI: PEG-30 HYDROGENATED CASTOR OIL LAURATE
A gentle emulsifier that helps mix oils and water, but may not suit those avoiding PEG compounds.
In plain English
This ingredient is a helper that allows oil and water to blend together in products like cleansers and lotions. It is made by attaching polyethylene glycol (PEG) chains to hydrogenated castor oil and lauric acid. In simple terms, it stops your face wash from separating into oily and watery layers, making it feel smooth and consistent.

Quick decision guide
Useful, but context matters
PEG-30 Hydrogenated Castor Oil 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-30 Hydrogenated Castor Oil 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic compound created by reacting hydrogenated castor oil with lauric acid and ethylene oxide (PEG). It acts as a surfactant and emulsifier.
How it works
Its molecular structure has both water-loving (hydrophilic) and oil-loving (lipophilic) parts, allowing it to reduce surface tension between oil and water. This helps create stable emulsions in creams and cleansers, and helps rinse away oils and dirt when you wash.
Pros
Effective emulsifier
Keeps oil and water mixed in products, so you get a consistent texture every time you use a cleanser or lotion.
Low irritation potential
Generally well-tolerated by most skin types, including sensitive skin, when used at typical concentrations.
Cons and cautions
PEG concerns
Some people choose to avoid PEG compounds because of potential impurities like 1,4-dioxane, though reputable brands purify their ingredients.
Not biodegradable
As a synthetic compound, it may not break down as easily in the environment compared to natural emulsifiers.
Best for
- People who use oil-based cleansers or makeup removers
- Those with normal to combination skin looking for gentle cleansing
Use caution if
- Individuals who prefer to avoid PEG compounds due to personal or environmental concerns
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. The main concern is potential trace contamination with 1,4-dioxane during manufacturing, but reputable suppliers control for this. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PEG compounds and found them safe as used.
Research notes
Limited direct studies on this specific compound, but the broader class of PEGylated castor oil derivatives is well-studied and considered safe. The CIR has evaluated related PEG compounds and concluded they are safe in cosmetics when formulated properly.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, subject to purity standards for PEG compounds.
- Common uses
- Cleansers, Makeup removers, Lotions, Creams
- Environmental note
- As a semi-synthetic ingredient, its biodegradability is lower than natural alternatives, but it is not considered a major environmental concern at typical usage levels.
Good to know
- PEG-30 Hydrogenated Castor Oil Laurate is often used in micellar waters and oil cleansers
- The number '30' refers to the average number of PEG units, which affects its water solubility
