Ingredient review
PPG-5 Laureth-5
INCI: PPG-5-LAURETH-5
A synthetic emulsifier that helps mix oil and water, but can be drying or irritating for sensitive skin.
In plain English
PPG-5 Laureth-5 is a man-made ingredient that helps oil and water stay blended in products like cleansers and shampoos. It's a type of surfactant, which means it helps lift dirt and oil from your skin or hair so they can be rinsed away. However, because it can strip natural oils, it may leave skin feeling tight or dry, especially if you have a sensitive or dry skin type.

Quick decision guide
Useful, but context matters
PPG-5 Laureth-5 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-5 Laureth-5.
- 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-5 Laureth-5 is a synthetic compound made by reacting propylene glycol with lauryl alcohol and ethylene oxide. It belongs to a class of ingredients called alkyl ether sulfates or ethoxylated alcohols, commonly used as mild surfactants and emulsifiers in personal care products.
How it works
In a cosmetic product, PPG-5 Laureth-5 reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. It also helps break down sebum and dirt on the skin or scalp, making them easier to wash away with water. Its mild foaming properties contribute to a pleasant cleansing experience.
Pros
Effective emulsifier
Helps oil and water blend smoothly, improving product texture and stability.
Good cleansing power
Removes excess oil and dirt effectively, making it useful for oily skin types.
Cons and cautions
Potential for irritation
Can strip natural oils, leading to dryness or irritation, especially for sensitive skin.
Ethoxylation concerns
The manufacturing process may leave trace amounts of 1,4-dioxane, a possible carcinogen, though levels are typically low.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who use rinse-off products like shampoos and body washes
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
- Anyone seeking a completely natural or non-ethoxylated ingredient
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. However, the ethoxylation process raises minor concerns about 1,4-dioxane contamination, and the ingredient can be drying for sensitive skin. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have reviewed similar ethoxylated surfactants and found them safe when formulated properly.
Research notes
Studies on ethoxylated surfactants indicate low acute toxicity and skin irritation at low concentrations, but higher concentrations or prolonged exposure may cause irritation. The potential for 1,4-dioxane contamination is well-documented, but levels in finished products are typically below safety thresholds set by regulators.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits for 1,4-dioxane typically below 10 ppm.
- Common uses
- Cleansers, Shampoos, Conditioners, Body washes
- Environmental note
- As a synthetic ethoxylated ingredient, it may have moderate biodegradability; some consumers prefer plant-based alternatives for environmental reasons.
Good to know
- PPG-5 Laureth-5 is often found in combination with other surfactants to balance cleansing strength.
- The 'PPG-5' part indicates the number of propylene glycol units, which affects its solubility and mildness.
