PEG/PPG-10/2 Diricinoleate
INCI: PEG/PPG-10/2 Diricinoleate
A reliable synthetic emulsifier that helps mix oil and water in formulas, generally well-tolerated but not a standout active ingredient.
In plain English
PEG/PPG-10/2 Diricinoleate is a man-made ingredient that helps oil and water stay blended together in products like lotions and cleansers. It's part of a family of PEG compounds, which are processed to be gentle and stable. While it's not a star active ingredient, it plays a supporting role in making textures smooth and consistent.

Quick decision guide
Useful, but context matters
PEG/PPG-10/2 Diricinoleate 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/PPG-10/2 Diricinoleate.
- 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 synthetic polymer made from ethylene oxide and propylene oxide reacted with diricinoleic acid (a derivative of castor oil). It belongs to the PEG/PPG family of emulsifiers.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This prevents products from separating and gives a smooth, uniform texture.
Pros
Effective emulsifier
Helps oil and water mix seamlessly, preventing separation and ensuring a consistent product texture.
Low irritation risk
Generally well-tolerated on skin, with a low likelihood of causing redness or stinging, even for sensitive skin types.
Cons and cautions
Not a functional active
It doesn't provide direct skin benefits like hydration or anti-aging; its role is purely structural in the formula.
Potential trace impurities
If not highly refined, it may contain trace levels of ethylene oxide or 1,4-dioxane, though reputable brands ensure purity.
Best for
- Anyone using lotions, creams, or cleansers that need a stable texture
- People with normal to oily skin looking for lightweight emulsions
Use caution if
- Those with known sensitivity to PEG compounds (rare)
- Individuals seeking purely natural or plant-based formulations
Usage tips
Safety summary
PEG/PPG-10/2 Diricinoleate is considered safe for cosmetic use at typical concentrations. The main concern is potential trace impurities from manufacturing, which are controlled by good manufacturing practices. It has low irritation and comedogenic risk.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and concluded they are safe for use in cosmetics. Individual studies on this specific ingredient are limited, but its safety profile is supported by the broader PEG family data.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU Cosmetics Regulation. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe as used.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Sunscreens
- Environmental note
- PEG/PPG compounds are synthetic and may not be biodegradable in all environments. However, they are used in low concentrations and are not known to bioaccumulate.
Good to know
- PEG/PPG compounds are common in cosmetics and are considered safe by major regulatory bodies when properly manufactured.
- The '10/2' refers to the average number of ethylene oxide and propylene oxide units, which affects its water- and oil-loving balance.
