Ingredient review
PEG/PPG-32/3 Diricinoleate
INCI: PEG/PPG-32/3 Diricinoleate
A reliable synthetic emulsifier that helps mix oil and water in creams and lotions, but may not suit those avoiding PEG compounds.
In plain English
This ingredient is a synthetic helper that allows oil and water to blend together smoothly in products like moisturizers and cleansers. It's part of a family of compounds called PEGs, which are widely used in cosmetics for their gentle cleansing and emulsifying properties. While generally considered safe, some people prefer to avoid PEGs due to concerns about potential contamination during manufacturing.

Quick decision guide
Useful, but context matters
PEG/PPG-32/3 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-32/3 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
PEG/PPG-32/3 Diricinoleate is a synthetic polymer made by reacting ethylene oxide and propylene oxide with diricinoleic acid (a derivative of castor oil). It belongs to the PEG (polyethylene glycol) family and is designed to act as an emulsifier and surfactant in cosmetic formulations.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. This helps create smooth, creamy textures in lotions and creams, and also helps cleanse the skin by trapping dirt and oil so they can be rinsed away.
Pros
Effective emulsifier
Creates stable, smooth mixtures of oil and water, preventing products from separating and ensuring a consistent texture.
Gentle cleanser
Helps remove dirt, oil, and makeup without stripping the skin's natural moisture barrier when used in appropriate concentrations.
Cons and cautions
Potential trace impurities
Manufacturing can produce trace amounts of 1,4-dioxane, a possible carcinogen, though cosmetic-grade PEGs are purified to meet safety limits.
Environmental persistence
PEG compounds are not readily biodegradable and can accumulate in waterways, raising ecological concerns.
Best for
- People who use conventional moisturizers, cleansers, or sunscreens
- Those looking for stable, non-separating cream textures
Use caution if
- Individuals who prefer to avoid PEG-based ingredients due to personal or environmental concerns
Usage tips
Safety summary
PEG/PPG-32/3 Diricinoleate is considered safe for use in cosmetics at typical concentrations, with low irritation and comedogenic potential. The main concern is potential contamination with 1,4-dioxane during manufacturing, but regulatory limits ensure consumer safety.
Research notes
Studies on PEG compounds indicate low acute toxicity and skin irritation. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEGs and found them safe as used. Research on environmental persistence is ongoing.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with concentration limits for impurities like 1,4-dioxane (typically ≤10 ppm).
- Common uses
- Moisturizers, Cleansers, Makeup removers, Sunscreens
- Environmental note
- PEG compounds are not readily biodegradable and may persist in the environment; however, wastewater treatment can reduce their impact.
Good to know
- PEG/PPG-32/3 Diricinoleate is often used in combination with other emulsifiers to achieve the desired texture and stability.
- The '32/3' refers to the average number of ethylene oxide and propylene oxide units, which affects its solubility and performance.
