Ingredient review
PEG-12 Ditallate
INCI: PEG-12 Ditallate
PEG-12 Ditallate is a synthetic cleanser ingredient that effectively removes dirt and oil, but may be slightly drying for sensitive skin.
In plain English
PEG-12 Ditallate is a man-made ingredient that helps cleansers mix water with oil and dirt so they can be rinsed away. It's a type of surfactant, which is the foaming or cleansing agent in many soaps and shampoos. Because it's derived from tall oil (a byproduct of wood pulp processing), it's considered a synthetic ingredient with some natural origins.

Quick decision guide
Useful, but context matters
PEG-12 Ditallate 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-12 Ditallate.
- 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-12 Ditallate is a polyethylene glycol (PEG) derivative of tall oil fatty acids. It's a surfactant that lowers the surface tension between water and oil, allowing them to mix and be washed away.
How it works
In a cosmetic product, PEG-12 Ditallate works by surrounding oil and dirt particles with its water-loving and oil-loving ends, forming tiny droplets that can be rinsed off with water. This makes it effective at cleansing without needing harsh scrubbing.
Pros
Strong cleanser
Effectively removes excess oil, makeup, and dirt, making it great for oily skin types.
Good lather
Creates a satisfying foam that helps spread the product evenly over skin or hair.
Cons and cautions
Potential irritation
Can strip natural oils and cause dryness or irritation, especially for sensitive or dry skin.
PEG purity concerns
PEG compounds may contain trace impurities like ethylene oxide if not manufactured to high standards.
Best for
- People with oily or combination skin looking for a deep cleanse
- Those who use rinse-off products like shampoos and body washes
Use caution if
- Individuals with very dry or sensitive skin
- Those who prefer only plant-based or naturally derived ingredients
Usage tips
Safety summary
PEG-12 Ditallate is generally considered safe for use in rinse-off cosmetics at typical concentrations. However, individuals with sensitive skin may experience dryness or irritation. The main safety concern is potential contamination with ethylene oxide during manufacturing, which is regulated.
Research notes
Research on PEG-12 Ditallate specifically is limited, but studies on PEG surfactants indicate they are effective cleansers with moderate irritation potential. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG compounds and found them safe when formulated properly.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) at typical concentrations. Manufacturers must ensure low levels of impurities like ethylene oxide.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- PEG-12 Ditallate is not readily biodegradable in all environments, so it may persist in water systems. Some regions have restrictions on PEG compounds for this reason.
Good to know
- PEG-12 Ditallate is derived from tall oil, a byproduct of the paper industry, not animal tallow.
- The number '12' refers to the average number of ethylene glycol units in the molecule, which affects its water solubility.
