Ingredient review
PEG-200 Glyceryl Tallowate
INCI: PEG-200 Glyceryl Tallowate
A gentle cleansing agent derived from tallow that helps remove dirt and oil without stripping the skin.
In plain English
PEG-200 Glyceryl Tallowate is a cleansing ingredient made from animal fat (tallow) that has been modified with PEG (polyethylene glycol) to make it water-soluble. It works by helping oil and water mix, so when you rinse, dirt and excess oil wash away easily. It's often used in gentle cleansers because it's less harsh than some other surfactants.

Quick decision guide
Useful, but context matters
PEG-200 Glyceryl Tallowate 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-200 Glyceryl Tallowate.
- 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 created by reacting tallow (rendered animal fat) with glycerin and then adding PEG chains to improve water solubility and mildness.
How it works
It lowers the surface tension between oil and water, allowing oils and dirt on the skin to be lifted away and rinsed off. Its large PEG chain makes it less penetrating and generally milder than shorter-chain PEG surfactants.
Pros
Gentle cleansing
Removes dirt and oil effectively without over-stripping the skin's natural moisture barrier, making it suitable for daily use.
Good lather
Creates a rich, creamy foam that feels pleasant during cleansing and rinses cleanly.
Cons and cautions
Animal-derived
Sourced from tallow, which may conflict with vegan or vegetarian lifestyles and some ethical preferences.
PEG concerns
The PEG component can be associated with potential impurities like ethylene oxide, though reputable manufacturers use purified grades.
Best for
- People with normal to dry skin looking for a gentle cleanser
- Those who prefer mild, non-stripping cleansing formulas
Use caution if
- Vegans and vegetarians who avoid animal-derived ingredients
- Individuals with known sensitivity to PEG compounds (rare)
Usage tips
Safety summary
Generally recognized as safe for use in rinse-off cosmetics at typical concentrations. Mild and well-tolerated by most skin types. As with all PEG compounds, quality control is important to minimize potential impurities.
Research notes
Limited direct studies on this specific ingredient, but it is structurally similar to other PEG glyceryl esters that have been evaluated for safety by the Cosmetic Ingredient Review (CIR) panel and found safe for use in cosmetics.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Subject to purity standards for PEG compounds.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- Tallow is a byproduct of the meat industry, so its use can be seen as utilizing waste. However, animal farming has a higher environmental footprint than plant-based alternatives.
Good to know
- PEG-200 Glyceryl Tallowate is considered biodegradable and is often used in 'gentle' or 'mild' cleanser formulations.
- The '200' refers to the average number of ethylene oxide units in the PEG chain, which influences its water solubility and mildness.
