Ingredient review
PEG-10 Tallate
INCI: PEG-10 TALLATE
PEG-10 Tallate is a cleansing and emulsifying ingredient derived from tall oil, but its PEG component and potential impurities raise mild safety considerations for sensitive skin.
In plain English
PEG-10 Tallate is a semi-synthetic ingredient made by combining polyethylene glycol (PEG) with fatty acids from tall oil, a byproduct of pine tree wood processing. In skincare and haircare, it helps blend oil and water so products can effectively remove dirt and makeup. It also helps create a foamy lather in cleansers. While generally considered safe, the PEG part can sometimes be contaminated with ethylene oxide or 1,4-dioxane during manufacturing, which is why many brands choose PEG-free alternatives.

Quick decision guide
Useful, but context matters
PEG-10 Tallate can be useful, but watch for some irritation potential.
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-10 Tallate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
PEG-10 Tallate is a polyethylene glycol ether of tall oil fatty acids. It functions as a non-ionic surfactant and emulsifier, meaning it helps mix oil and water and reduces surface tension to lift away grime.
How it works
In a cosmetic formula, PEG-10 Tallate sits at the interface between oil and water droplets, stabilizing the mixture so the product doesn't separate. Its surfactant properties also help break down sebum and makeup on the skin, allowing them to be rinsed away with water.
Pros
Effective cleanser
PEG-10 Tallate efficiently removes excess oil, sunscreen, and makeup without stripping the skin completely, making it a good choice for daily cleansing.
Stabilizes formulas
It helps keep oil and water mixed in a product, preventing separation and ensuring a consistent texture from first use to last.
Cons and cautions
Potential impurities
As a PEG derivative, it may contain trace levels of 1,4-dioxane, a possible carcinogen, unless the manufacturer uses purification steps. This is a concern for some consumers.
Mild irritation risk
Surfactants like PEG-10 Tallate can disrupt the skin barrier if used in high concentrations or on already irritated skin, leading to dryness or stinging.
Best for
- People with normal to oily skin looking for effective cleansers
- Those who use rinse-off products like shampoos and body washes
Use caution if
- Individuals with very sensitive, reactive, or eczema-prone skin who prefer PEG-free formulations
Usage tips
Safety summary
PEG-10 Tallate is considered safe for use in rinse-off cosmetics at typical concentrations, but the potential for 1,4-dioxane contamination means consumers may prefer PEG-free alternatives for daily use on sensitive skin.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found PEG derivatives generally safe when impurities are controlled. No specific studies on PEG-10 Tallate alone were identified, but its class is well-documented.
Common label clues
- Typical concentration
- Usually 1–10% of the formula
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits for impurities like 1,4-dioxane (typically ≤10 ppm in finished products).
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- Tall oil is a renewable resource derived from pine wood processing, but the PEG portion is petroleum-derived. The ingredient is not readily biodegradable in all environments.
Good to know
- PEG-10 Tallate is not the same as PEG-10 dimethicone or other PEGs—each has a different function.
- Tall oil is a renewable byproduct of the paper industry, making this ingredient more sustainable than some petroleum-based alternatives.
- The number '10' refers to the average length of the PEG chain, which affects its water solubility.
