Ingredient review
TEA-PEG-50 Hydrogenated Castor Oil Succinate
INCI: TEA-PEG-50 HYDROGENATED CASTOR OIL SUCCINATE
A mild, castor-oil-derived emulsifier that helps rinse away makeup and sunscreen without stripping the skin.
In plain English
This ingredient is a modified castor oil that has been chemically processed to help water and oil mix together. In a cleanser, it grabs onto makeup and sunscreen so they can be rinsed away easily. Because it's derived from castor oil and made to be gentle, it's less likely to cause irritation or dryness compared to harsher cleansing agents.

Quick decision guide
Useful, but context matters
TEA-PEG-50 Hydrogenated Castor Oil Succinate 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 TEA-PEG-50 Hydrogenated Castor Oil Succinate.
- 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 surfactant and emulsifier created by reacting hydrogenated castor oil with PEG-50 and succinic acid. It appears as a waxy solid or viscous liquid and is used to stabilize oil-in-water emulsions.
How it works
Its molecular structure has both water-loving (hydrophilic) and oil-loving (lipophilic) parts. When you apply a product containing it, the oil-loving tails surround dirt and oil, while the water-loving heads allow everything to be rinsed away with water. This makes it effective at removing waterproof makeup and excess sebum without harsh scrubbing.
Pros
Gentle on skin
Derived from castor oil and modified to be mild, it cleans without stripping the skin's natural moisture barrier, making it ideal for daily use.
Effective makeup remover
Its dual nature allows it to dissolve both water-resistant and oil-based impurities, so you can remove sunscreen and foundation in one step.
Cons and cautions
May leave a slight film
Some users with very oily skin might notice a light residue after rinsing, which could feel less clean than foaming cleansers.
Limited heavy-duty cleansing
For extremely long-wear or waterproof makeup, you may still need a dedicated oil cleanser or micellar water as a first step.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone who wears light to moderate makeup or sunscreen daily
Use caution if
- Those who prefer completely oil-free or minimal-ingredient routines
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic risk. Rare reports of mild sensitivity in very reactive skin.
Research notes
Limited direct studies on this specific compound, but its components (hydrogenated castor oil, PEG derivatives) have a long history of safe use in cosmetics. The Cosmetic Ingredient Review (CIR) panel has evaluated related PEG castor oil derivatives and found them safe as used.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions at typical use levels.
- Common uses
- Cleansers, Makeup removers, Facial washes, Shampoos
- Environmental note
- Derived from renewable castor oil, but the PEG (polyethylene glycol) component is synthetic and may not be fully biodegradable. Always check brand sustainability claims.
Good to know
- PEG-50 indicates a moderate degree of ethoxylation, which balances mildness with cleansing power.
- Hydrogenated castor oil is a common base for many gentle emulsifiers in natural-leaning formulations.
