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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There 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

Use in oil-based or cream cleansers for a gentle, non-stripping wash.
Pair with other mild surfactants to create a balanced cleansing formula.

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.
