Ingredient review
PEG-2 Olive Glycerides
INCI: PEG-2 OLIVE GLYCERIDES
A gentle, olive-derived emulsifier that helps blend oil and water in skincare formulas without stripping the skin.
In plain English
PEG-2 Olive Glycerides is a semi-synthetic ingredient made by combining olive oil glycerides with a small amount of polyethylene glycol (PEG). It acts as a bridge between oil and water, allowing them to mix into a stable cream or lotion. Because it comes from olive oil, it is considered milder and more skin-friendly than many harsher detergents. It also helps condition the skin, leaving it feeling soft and smooth after use.

Quick decision guide
Useful, but context matters
PEG-2 Olive 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-2 Olive 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 emulsifier created by reacting olive oil glycerides with ethylene oxide (PEG-2). The olive oil part provides a natural, moisturizing base, while the PEG chain gives it water-loving properties.
How it works
In a cosmetic formula, PEG-2 Olive Glycerides sits at the boundary between oil and water droplets, reducing surface tension so they stay mixed. This creates a stable, uniform product. On the skin, it deposits a thin, non-greasy film that helps retain moisture and improves skin feel.
Pros
Gentle on skin
Unlike harsh sulfates, PEG-2 Olive Glycerides cleanses without stripping the skin's natural moisture barrier, making it suitable for daily use.
Improves product texture
It helps create smooth, creamy formulas that feel luxurious and spread easily, enhancing the user experience.
Cons and cautions
PEG-related purity concerns
The manufacturing process can introduce trace impurities like 1,4-dioxane, though reputable brands ensure levels are within safe limits set by regulators.
Not fully natural
Despite the olive oil origin, the PEG modification means it is semi-synthetic, which may not appeal to those seeking 100% natural products.
Best for
- People with normal to dry skin who want a gentle, non-stripping cleanser or moisturizer
- Those who prefer products with plant-derived ingredients and mild emulsifiers
Use caution if
- Individuals with known sensitivity to PEG compounds or olive-derived ingredients
Usage tips
Safety summary
PEG-2 Olive Glycerides is considered safe for cosmetic use at typical concentrations. The main concern is potential contamination with 1,4-dioxane, but this is tightly regulated. It has low irritation and comedogenic potential, making it suitable for most skin types.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG compounds are safe when formulated to meet purity standards. Studies on olive-derived glycerides show good skin compatibility and moisturizing properties.
Common label clues
- Typical concentration
- Typically 1–5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. Manufacturers are required to limit impurities like 1,4-dioxane to safe levels (typically below 10 ppm).
- Common uses
- Cleansers, Moisturizers, Lotions, Creams
- Environmental note
- Olive oil is a renewable resource, but the PEG process involves petrochemical-derived ethylene oxide. Overall, it has a moderate environmental footprint compared to fully synthetic emulsifiers.
Good to know
- PEG-2 Olive Glycerides is often used in 'gentle' or 'hydrating' cleansers and creams.
- The '2' in PEG-2 indicates a short PEG chain, which reduces the risk of irritation compared to longer-chain PEGs.
