PEG-25 Avocado Oil Glyceryl Esters
INCI: PEG-25 Avocado Oil Glyceryl Esters
A gentle emulsifier that helps blend oil and water in skincare formulas, with mild conditioning benefits from avocado oil.
In plain English
This ingredient is a helper that mixes oil and water so they don't separate in your lotion or cleanser. It's made by attaching a small chain of PEG (polyethylene glycol) to avocado oil glycerides, which makes the avocado oil more water-friendly. In a product, it helps create a smooth, stable texture and can leave skin feeling slightly softer without being greasy.

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 avocado oil glycerides with ethylene oxide (PEG). It acts as a non-ionic surfactant and emulsifier, meaning it helps oil and water blend together in cosmetic formulas.
How it works
The PEG chain makes the ingredient water-soluble, while the avocado oil portion remains oil-loving. When mixed into a formula, it positions itself at the boundary between oil and water droplets, stabilizing the emulsion so the product stays creamy and doesn't separate. It also reduces surface tension, which helps spread the product evenly on skin.
Pros
Gentle emulsifier
It effectively blends oil and water without being harsh, making it suitable for sensitive skin formulas.
Adds mild softness
The avocado oil component provides a light conditioning effect, leaving skin feeling smoother after use.
Cons and cautions
PEG purity concerns
Like all PEG compounds, manufacturing can leave trace impurities such as 1,4-dioxane if not properly refined, though reputable brands ensure purification.
Not natural
It is semi-synthetic, which may be a turn-off for consumers seeking fully natural or plant-based ingredients.
Best for
- Anyone using lotions, creams, or cleansers that need a stable texture
- People with normal to dry skin who want mild conditioning
Use caution if
- Those who strictly avoid PEG-derived ingredients due to personal preference
Usage tips
Safety summary
PEG-25 Avocado Oil Glyceryl Esters is considered safe for cosmetic use at typical concentrations. The main safety consideration is the potential for trace 1,4-dioxane contamination during manufacturing, but reputable suppliers purify the ingredient to meet safety standards. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have reviewed PEG compounds and found them safe for topical use.
Research notes
Research on this specific ingredient is limited, but the safety of PEG compounds and avocado oil derivatives is well-documented. The CIR has evaluated PEGs and concluded they are safe in cosmetics when formulated to minimize impurities. Avocado oil itself has been studied for its moisturizing and anti-inflammatory properties.
Common label clues
- Typical concentration
- 1–5% in rinse-off products; 0.5–3% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The PEG chain length (25) is considered safe for topical use when properly manufactured.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves ethylene oxide, which is derived from fossil fuels. Some environmental groups prefer plant-based alternatives.
Good to know
- PEG-25 indicates the average number of ethylene oxide units in the PEG chain.
- Avocado oil is rich in oleic acid and vitamin E, which contribute to its conditioning properties.
- This ingredient is often used in makeup removers because it helps dissolve makeup while being gentle.
