Ingredient review
PPG-8 Sorbitol Castor Oil
INCI: PPG-8 SORBITOL CASTOR OIL
A gentle, semi-synthetic ingredient that helps products feel smooth and spread easily without clogging pores.
In plain English
PPG-8 Sorbitol Castor Oil is a modified version of castor oil combined with sorbitol (a sugar alcohol) and propylene glycol chains. This makes it more water-friendly and less greasy than plain castor oil. In skincare, it acts as an emollient to soften skin and as an emulsifier to help oil and water mix in creams and lotions. It's often used in makeup removers because it can dissolve stubborn makeup without leaving a heavy residue.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.

- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 compound created by reacting castor oil with sorbitol and propylene oxide (PPG-8). The result is a clear, viscous liquid that is more hydrophilic (water-loving) than natural castor oil, making it easier to formulate into water-based products.
How it works
It reduces surface tension between oil and water, allowing them to blend into a stable emulsion. As an emollient, it fills the spaces between skin cells, smoothing the skin's surface and improving texture. Its mild cleansing properties help lift dirt and makeup without stripping the skin's natural oils.
Pros
Lightweight feel
Unlike pure castor oil, this modified version feels light and non-greasy, making it ideal for daytime moisturizers and serums.
Gentle cleanser
It effectively dissolves makeup and sunscreen without harsh surfactants, reducing the risk of irritation for sensitive skin.
Cons and cautions
Semi-synthetic process
The chemical modification (PPG-8) means it's not a natural ingredient, which may be a drawback for those seeking fully natural formulations.
Limited independent research
Most safety data comes from manufacturer studies; long-term independent research on this specific compound is sparse.
Best for
- People with normal to oily skin looking for a lightweight emollient
- Anyone who uses makeup removers or cleansing balms
Use caution if
- Those with known allergies to castor oil derivatives (rare)
- Strict 'natural only' skincare users
