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 TEA-Diricinoleate.
- 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
TEA-Diricinoleate is a semi-synthetic compound formed by reacting triethanolamine with diricinoleic acid, a fatty acid derived from castor oil. It acts as an emulsifier and surfactant.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps create smooth, uniform creams and lotions that don't separate.
Pros
Gentle emulsifier
TEA-Diricinoleate is mild and unlikely to cause irritation, making it suitable for sensitive skin formulations.
Stable formulas
It helps create stable emulsions that keep products consistent and effective over time.
Cons and cautions
Potential dryness
In high concentrations, it may strip natural oils, leading to dryness for those with already dry skin.
Limited data
There is less published research on this specific ingredient compared to more common emulsifiers.
Best for
- People with normal to oily skin
- Those looking for gentle emulsifiers in cleansers
Use caution if
- Individuals with extremely dry or compromised skin barriers
