Ingredient review
PPG-25 Laureth-25
INCI: PPG-25-Laureth-25
A synthetic emulsifier that helps mix oil and water in cleansers, but may be drying or irritating for sensitive skin.
In plain English
PPG-25 Laureth-25 is a man-made ingredient that helps oil and water blend together in products like cleansers and shampoos. It works as a surfactant, meaning it helps lift dirt and oil from your skin or hair so they can be rinsed away. While effective, it can be a bit harsh for very dry or sensitive skin because it can strip away natural oils.

Quick decision guide
Useful, but context matters
PPG-25 Laureth-25 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-25 Laureth-25.
- 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-25 Laureth-25 is a synthetic polymer surfactant, part of the Laureth family. It is created by reacting lauryl alcohol with ethylene oxide and propylene oxide, resulting in a molecule that can dissolve both oil and water.
How it works
In a cosmetic product, PPG-25 Laureth-25 sits at the boundary between oil and water droplets, reducing surface tension so they mix into a stable emulsion. During cleansing, it surrounds dirt and oil particles, allowing them to be lifted away and rinsed off with water.
Pros
Effective emulsifier
Stabilizes oil-and-water blends, giving cleansers a smooth, consistent texture that rinses cleanly.
Good makeup remover
Helps dissolve stubborn makeup and sunscreen without requiring harsh scrubbing.
Cons and cautions
Potential drying effect
As a surfactant, it can strip the skin's natural moisture barrier, leading to tightness or dryness after washing.
Moderate irritation risk
May cause stinging or redness for those with sensitive or compromised skin, especially in high concentrations.
Best for
- People with normal to oily skin looking for effective cleansers
- Those who wear heavy makeup or sunscreen and need thorough removal
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
- Anyone who prefers entirely natural or plant-based ingredients
Usage tips
Safety summary
PPG-25 Laureth-25 is considered safe for use in rinse-off cosmetics at typical concentrations. It can be drying or irritating for sensitive skin, but is well-tolerated by most people with normal skin.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found Laureth-type surfactants to be safe in rinse-off products. Studies indicate low skin penetration and no significant toxicity, though irritation potential varies by individual.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with no specific concentration restrictions for rinse-off products.
- Common uses
- Cleansers, Shampoos, Conditioners, Body washes, Makeup removers
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable. Look for products with eco-friendly surfactant blends if this is a concern.
Good to know
- PPG-25 Laureth-25 is often found in rinse-off products, not leave-on formulas, to minimize skin contact.
- It is considered safe in cosmetics by major regulatory bodies when used as directed.
