Ingredient review
Apricot Kernel Oil PEG-40 Esters
INCI: APRICOT KERNEL OIL PEG-40 ESTERS
A gentle emulsifier that helps mix oil and water, making cleansers and lotions feel smooth without heavy residue.
In plain English
This ingredient is a modified version of apricot kernel oil that has been combined with PEG (polyethylene glycol) to make it water-friendly. In simple terms, it acts as a bridge between oil and water, allowing them to blend into a stable, creamy product. It is commonly used in cleansers and moisturizers to create a smooth texture that rinses off easily without leaving a greasy feel.
Quick decision guide

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 apricot kernel oil with PEG-40, a polyethylene glycol chain. This process makes the oil dispersible in water, turning it into a mild cleansing and emulsifying agent.
How it works
The PEG chain attaches to water molecules while the apricot oil portion attracts oils and dirt. When you rinse, the ingredient helps lift away impurities and allows the product to wash off cleanly, leaving skin feeling soft rather than stripped.
Pros
Gentle emulsifier
It blends oil and water into a stable cream without harsh surfactants, making cleansers feel mild and non-stripping.
Improves rinse-off
Products with this ingredient wash away cleanly, leaving skin soft and hydrated rather than greasy or tight.
Cons and cautions
Semi-synthetic origin
Because it is chemically modified with PEG, it may not appeal to those seeking exclusively natural ingredients.
Potential processing impurities
If not manufactured to high standards, PEG compounds can contain trace levels of ethylene oxide or 1,4-dioxane, though reputable brands ensure purification.
Best for
- People who use creamy cleansers or lotions
- Those with normal to dry skin looking for gentle cleansing
Use caution if
- Individuals with known sensitivity to PEG compounds (rare)
- Strict adherents to 100% natural ingredient routines
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. The main concern is potential impurities from PEG manufacturing, but reputable suppliers and brands ensure proper purification. Irritation and allergy are rare.
Research notes
Limited direct studies on this specific ester, but PEG-based emulsifiers are well-documented as safe and effective in cosmetics. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PEG compounds and found them safe for use.
Common label clues
- Typical concentration
- 1% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. PEG compounds are regulated and must meet purity standards to minimize impurities.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Lotions
- Environmental note
- Apricot kernel oil is a byproduct of the fruit industry, making it a relatively sustainable source. PEG compounds are biodegradable but derived from petrochemicals.
Good to know
- PEG-40 refers to the length of the polyethylene glycol chain, which determines how water-friendly the ingredient becomes.
- Apricot kernel oil is naturally rich in oleic and linoleic acids, which can help support skin barrier function.
