Ingredient review
PPG-20 Laureth-12
INCI: PPG-20 Laureth-12
A synthetic emulsifier that helps mix oil and water, but may cause mild irritation for sensitive skin.
In plain English
PPG-20 Laureth-12 is a man-made ingredient that helps oil and water stay mixed together in products like cleansers and lotions. It also helps create foam and remove dirt. While effective, it can be slightly drying or irritating for people with very sensitive or reactive skin.

Quick decision guide
Useful, but context matters
PPG-20 Laureth-12 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 PPG-20 Laureth-12.
- 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
PPG-20 Laureth-12 is a synthetic polymer made from propylene glycol and lauryl alcohol, modified with ethylene oxide. It belongs to the ethoxylated surfactant family and is used primarily as an emulsifier and cleansing agent.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable emulsion. In cleansers, it helps lift dirt and oil from the skin so they can be rinsed away. Its mild foaming properties make it useful in rinse-off products.
Pros
Effective emulsifier
Stabilizes oil-and-water blends, giving lotions and cleansers a smooth, uniform texture.
Good cleansing power
Helps remove excess oil and impurities without being overly harsh for most skin types.
Cons and cautions
Potential irritation
May cause stinging, redness, or dryness for those with sensitive or reactive skin, especially in leave-on products.
Ethoxylation concerns
As an ethoxylated ingredient, it may contain trace amounts of 1,4-dioxane, a potential contaminant, though levels are typically low in well-manufactured products.
Best for
- People with normal to oily skin looking for effective cleansers
- Those using rinse-off products like shampoos and body washes
Use caution if
- Individuals with very sensitive, eczema-prone, or compromised skin barriers
Usage tips
Safety summary
Generally safe for most people in rinse-off products at low concentrations. The main concern is potential mild irritation for sensitive skin and trace impurities from the manufacturing process. Regulatory bodies consider it safe when used as intended.
Research notes
Studies on PPG-20 Laureth-12 specifically are limited, but the broader class of ethoxylated surfactants is well-studied. Research indicates low acute toxicity and skin irritation potential at typical use levels, with occasional sensitization in sensitive individuals.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) at typical concentrations. Manufacturers are encouraged to minimize 1,4-dioxane impurities through purification.
- Common uses
- Cleansers, Shampoos, Body washes, Lotions
- Environmental note
- As a synthetic ethoxylated compound, it may have moderate biodegradability. Some consumers prefer plant-based alternatives for environmental reasons.
Good to know
- PPG-20 Laureth-12 is often found in sulfate-free cleanser blends to boost mild foaming.
- The 'PPG-20' and 'Laureth-12' numbers refer to the length of the polymer chain, which affects its solubility and mildness.
