PPG-3 Hydrogenated Castor Oil
INCI: PPG-3 Hydrogenated Castor Oil
A gentle, semi-synthetic emollient that helps soften skin and stabilize formulas without heavy greasiness.
In plain English
PPG-3 Hydrogenated Castor Oil is a modified version of castor oil that has been processed to make it more stable and less greasy. It helps moisturize the skin by forming a light, protective layer that reduces water loss, and it also helps mix oil and water ingredients together in products like lotions and creams.

Quick decision guide
Useful, but context matters
PPG-3 Hydrogenated Castor Oil 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 PPG-3 Hydrogenated Castor Oil.
- 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 ingredient derived from castor oil through hydrogenation and propoxylation, creating a stable, non-greasy emollient and emulsifier.
How it works
It sits on the skin's surface to soften and smooth by reducing water evaporation (occlusive effect), and its emulsifying properties help blend oil and water phases in formulations for a uniform texture.
Pros
Lightweight feel
Unlike pure castor oil, this modified version feels less heavy and greasy, making it comfortable for daily use on face and body.
Formula-friendly
Acts as both an emollient and emulsifier, helping products maintain a smooth, stable texture without separating.
Cons and cautions
Semi-synthetic origin
The chemical modification process may not align with preferences for entirely natural or organic skincare ingredients.
Potential for mild irritation
While generally well-tolerated, a small number of people with very reactive skin might experience mild redness or irritation, especially at higher concentrations.
Best for
- People with normal to dry skin seeking light moisture
- Those who prefer non-greasy emollients in lotions or creams
Use caution if
- Individuals with known castor oil allergy
- Those seeking 100% natural ingredients
