Ingredient review
PEG-30 Glyceryl Laurate
INCI: PEG-30 Glyceryl Laurate
A gentle emulsifier that helps mix oils and water, but may not suit those avoiding PEG compounds.
In plain English
PEG-30 Glyceryl Laurate is a helper ingredient that allows oil and water to blend together in products like cleansers and lotions. It is made by attaching polyethylene glycol (PEG) to a fatty acid from coconut or palm oil. This makes it a mild surfactant that can gently lift dirt and oil without stripping the skin.

Quick decision guide
Useful, but context matters
PEG-30 Glyceryl 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 Glyceryl 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 emulsifier created by reacting lauric acid (from coconut or palm oil) with ethylene oxide to form a PEG chain of about 30 units. It belongs to the glyceryl ester family and is commonly used in rinse-off products.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. In cleansers, it helps disperse oils and dirt so they can be rinsed away easily. Its mild surfactant properties make it less likely to irritate than harsher cleansing agents.
Pros
Gentle cleanser
It effectively removes dirt and oil without stripping the skin's natural moisture barrier, making it suitable for daily use.
Stable emulsions
It helps create smooth, creamy textures in lotions and cleansers that don't separate over time.
Cons and cautions
Ethoxylation concerns
As a PEG compound, it may contain trace amounts of 1,4-dioxane, a potential contaminant. Reputable manufacturers purify to low levels, but some consumers prefer to avoid it.
Not eco-friendly
PEG compounds can be slow to biodegrade and may have environmental persistence concerns.
Best for
- People with normal to dry skin looking for gentle cleansers
- Those who prefer mild, non-stripping surfactants
Use caution if
- Individuals who avoid PEGs or ethoxylated ingredients due to personal preference or sensitivity
Usage tips
Safety summary
PEG-30 Glyceryl Laurate is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with 1,4-dioxane during manufacturing, but reputable brands use purification steps to keep levels well below safety limits.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed PEG glyceryl esters and concluded they are safe as used in cosmetics. No significant skin irritation or sensitization was observed in clinical studies at typical use levels.
Common label clues
- Typical concentration
- 1–5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The CIR panel has deemed it safe at concentrations up to 10% in rinse-off products.
- Common uses
- Cleansers, Shampoos, Body washes, Lotions
- Environmental note
- PEG compounds are not readily biodegradable and may accumulate in aquatic environments. Some manufacturers are moving toward biodegradable alternatives.
Good to know
- PEG-30 Glyceryl Laurate is often used in combination with other emulsifiers to improve texture.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
