Ingredient review
PPG-4 Laureth-7
INCI: PPG-4 LAURETH-7
A synthetic emulsifier that helps mix oil and water in cleansers, but may be drying or irritating for sensitive skin.
In plain English
PPG-4 Laureth-7 is a man-made ingredient that helps oil and water stay blended in products like face washes and shampoos. It is a type of surfactant, which means it helps lift dirt and oil from your skin so they can be rinsed away. However, because it can be strong, it may strip natural oils and cause dryness or irritation, especially if you have sensitive or dry skin.

Quick decision guide
Useful, but context matters
PPG-4 Laureth-7 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-4 Laureth-7.
- 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-4 Laureth-7 is a synthetic polymer surfactant made from propylene glycol and lauryl alcohol. It belongs to the 'Laureth' family of emulsifiers, which are commonly used in rinse-off products to create stable mixtures of oil and water.
How it works
In a cosmetic product, PPG-4 Laureth-7 reduces the surface tension between oil and water, allowing them to mix into a smooth lotion or cream. It also helps break down sebum and dirt on the skin's surface, making it easier to wash away with water.
Pros
Effective emulsifier
Helps oil and water blend smoothly, creating stable lotions and cleansers that feel consistent and perform well.
Good cleansing power
Lifts excess oil and impurities from the skin, making it useful for oily or combination skin types.
Cons and cautions
Potential for dryness
Can strip the skin of natural oils, leading to tightness or flakiness, especially in dry or sensitive skin.
Irritation risk
At higher concentrations or with frequent use, it may cause redness or stinging, particularly for those with eczema or rosacea.
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 dry, sensitive, or compromised skin barriers
Usage tips
Safety summary
PPG-4 Laureth-7 is considered safe for use in rinse-off cosmetics at typical concentrations. However, it can be drying or irritating for sensitive skin, so patch testing is recommended for those with reactive skin.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found Laureth-type surfactants to be safe in rinse-off products when formulated correctly. Limited peer-reviewed studies focus specifically on PPG-4 Laureth-7, but its chemical class is well-understood.
Common label clues
- Typical concentration
- 0.5–5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific restrictions at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Emulsions
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable. Some manufacturers are moving toward more eco-friendly alternatives.
Good to know
- Often found in combination with other mild surfactants to reduce irritation.
- The 'PPG-4' part indicates a polymer chain that makes the ingredient less harsh than some simpler surfactants.
