Ingredient review
PEG-60 Evening Primrose Glycerides
INCI: PEG-60 Evening Primrose Glycerides
A gentle, water-soluble emollient that adds softness without greasiness, ideal for sensitive and dry skin types.
In plain English
PEG-60 Evening Primrose Glycerides is a modified version of evening primrose oil, made water-friendly by attaching PEG (polyethylene glycol) chains. This allows it to mix easily into water-based products like serums and cleansers while still delivering the skin-softening benefits of the original oil. It helps reduce water loss from the skin and leaves a smooth, non-greasy feel.

Quick decision guide
Useful, but context matters
PEG-60 Evening Primrose 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging PEG-60 Evening Primrose Glycerides.
- 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 ingredient created by reacting evening primrose oil with PEG (polyethylene glycol) to form glycerides that are water-soluble. It retains the fatty acid profile of evening primrose oil, including gamma-linolenic acid (GLA), but can be incorporated into clear or lightweight formulas.
How it works
It sits on the skin's surface to form a thin, protective film that slows water evaporation (transepidermal water loss, or TEWL). Its PEG component allows it to rinse off easily with water, making it useful in cleansers that condition without leaving a heavy residue.
Pros
Lightweight hydration
Delivers the emollient benefits of evening primrose oil without a heavy, greasy feel, making it comfortable for daily use on most skin types.
Gentle on skin
Low irritation and comedogenic risk, so it's unlikely to clog pores or cause breakouts, even for sensitive or acne-prone skin.
Cons and cautions
PEG-related concerns
Some consumers prefer to avoid PEG ingredients due to potential manufacturing impurities, though cosmetic-grade versions are purified and considered safe by regulators.
Not a standalone moisturizer
Works best as part of a formula with other humectants and occlusives; on its own, it provides only modest hydration.
Best for
- People with dry or dehydrated skin looking for a lightweight emollient
- Those with sensitive skin who want a gentle, non-irritating moisturizer
Use caution if
- Individuals with a known allergy to evening primrose oil or PEG compounds
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. Low irritation and comedogenic risk. Individuals with very sensitive skin or PEG allergies should patch test first.
Research notes
Evening primrose oil has been studied for its anti-inflammatory and barrier-supporting properties. PEG modification is a well-established technique to improve water solubility without significantly altering safety profile.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Cosmetic-grade PEGs are purified to minimize impurities like 1,4-dioxane.
- Common uses
- Cleansers, Moisturizers, Toners, Serums
- Environmental note
- PEG compounds are generally biodegradable, but their production involves petrochemicals. Evening primrose oil is typically sourced from cultivated plants.
Good to know
- Evening primrose oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid known for its skin-soothing properties.
- PEG-60 indicates the average number of ethylene oxide units, which affects water solubility and mildness.
