Ingredient review
PEG/PPG-32/3 Ricinoleate
INCI: PEG/PPG-32/3 Ricinoleate
A reliable emulsifier that helps mix oil and water in cleansers and creams, but may not suit those avoiding PEG compounds.
In plain English
This ingredient is a helper molecule that allows oil and water to blend together in a product, so you don't get a separated, watery mess. It's made by attaching polyethylene glycol (PEG) and polypropylene glycol (PPG) chains to ricinoleic acid, a fatty acid from castor oil. In practice, it makes cleansers feel smooth and helps creams stay creamy. Because it's semi-synthetic, it's generally well-tolerated, but some people prefer to avoid PEGs due to potential contamination concerns during manufacturing.

Quick decision guide
Useful, but context matters
PEG/PPG-32/3 Ricinoleate 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-32/3 Ricinoleate.
- 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 castor oil-derived ricinoleic acid with PEG and PPG chains. It belongs to a class of ingredients that reduce surface tension between oil and water, allowing them to form a stable mixture.
How it works
In a cosmetic product, PEG/PPG-32/3 Ricinoleate positions itself at the boundary between oil and water droplets. Its water-loving (PEG/PPG) end dissolves in water, while its oil-loving (ricinoleate) end dissolves in oil. This stabilizes the emulsion, preventing separation and giving the product a uniform texture.
Pros
Effective Emulsion Stabilizer
Prevents oil and water from separating, ensuring your lotion or cream stays smooth and consistent from first use to last.
Gentle on Skin
Has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Cons and cautions
PEG-Related Concerns
As a PEG derivative, it may contain trace impurities like ethylene oxide or 1,4-dioxane, which some consumers prefer to avoid.
Not Natural
It is semi-synthetic, so it won't appeal to those seeking 100% natural or organic skincare ingredients.
Best for
- People using oil-based cleansers or makeup removers who want a stable, effective formula
- Those with normal to oily skin looking for a gentle emulsifier
Use caution if
- Individuals who specifically avoid PEG compounds due to personal preference or sensitivity
Usage tips
Safety summary
Generally recognized as safe for cosmetic use at typical concentrations. The main concern is potential trace impurities from PEG manufacturing, but reputable brands purify their raw materials to minimize risk.
