Ingredient review
PEG-11 Avocado Glycerides
INCI: PEG-11 Avocado Glycerides
A gentle emulsifier that helps blend oil and water while adding a touch of avocado-derived nourishment.
In plain English
PEG-11 Avocado Glycerides is a semi-synthetic ingredient made by combining avocado oil with a small amount of polyethylene glycol (PEG). It acts as a bridge between oil and water in formulas, so creams and lotions stay smooth and don't separate. It also leaves skin feeling soft and conditioned, without a greasy residue.

Quick decision guide
Useful, but context matters
PEG-11 Avocado 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-11 Avocado 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 modified avocado oil derivative where 11 units of ethylene glycol (PEG) are attached to avocado glycerides. This process creates a water-soluble emulsifier that retains some of avocado oil's skin-friendly fatty acids.
How it works
In a formula, the PEG chain attracts water while the avocado glyceride part attracts oil. This dual nature allows it to stabilize emulsions (mixtures of oil and water), preventing them from splitting. It also deposits a thin, non-greasy film on the skin that helps lock in moisture.
Pros
Gentle emulsifier
PEG-11 Avocado Glycerides is known for its low irritation potential, making it a good choice for sensitive skin formulations.
Light conditioning
It provides a soft, smooth feel on the skin without the heavy, greasy residue that some oils leave behind.
Cons and cautions
PEG concerns
As a PEG derivative, there is a theoretical risk of contamination with ethylene oxide or 1,4-dioxane during manufacturing, though reputable suppliers use purified grades.
Not fully natural
Despite being derived from avocado oil, the addition of PEG makes it semi-synthetic, which may not align with 'natural-only' skincare preferences.
Best for
- Anyone looking for a gentle, non-irritating emulsifier in their moisturizer or cleanser
- People with dry or normal skin who want light conditioning without heavy oils
Use caution if
- Those who strictly avoid PEG-derived ingredients due to personal preference or ethical sourcing concerns
Usage tips
Safety summary
PEG-11 Avocado Glycerides is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace impurities in PEG, but cosmetic-grade ingredients are purified to meet safety standards. Overall, it has a low risk of irritation or comedogenicity.
Research notes
There is limited direct research on PEG-11 Avocado Glycerides itself, but its components—avocado oil and PEG—are well-studied. Avocado oil is known for its moisturizing and anti-inflammatory properties, while PEGs are widely used as safe emulsifiers. The Cosmetic Ingredient Review (CIR) panel has reviewed PEGs and found them safe for cosmetic use when properly formulated.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products; up to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Avocado oil is a renewable plant resource, but large-scale avocado farming can have environmental impacts such as water use and deforestation. PEG is derived from petroleum, adding a non-renewable component.
Good to know
- PEG-11 Avocado Glycerides is often used in 'oil-in-water' emulsions, which are the most common type of moisturizer.
- The number '11' refers to the average number of ethylene glycol units, which determines its water solubility and mildness.
