Ingredient review
PPG-2-Deceth-7
INCI: PPG-2-Deceth-7
A mild synthetic emulsifier that helps mix oil and water, generally well-tolerated but best for rinse-off products.
In plain English
PPG-2-Deceth-7 is a man-made ingredient that helps oil and water blend together in products like cleansers and shampoos. It is a type of surfactant, which means it can also help lift dirt and oil from the skin or hair so they rinse away easily. Because it is designed to be gentle, it is less likely to cause irritation than some stronger cleansing agents.

Quick decision guide
Useful, but context matters
PPG-2-Deceth-7 is generally a lower-concern ingredient when the full formula suits your skin.
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-2-Deceth-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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
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-2-Deceth-7 is a synthetic, non-ionic surfactant and emulsifier derived from decyl alcohol and ethylene oxide/propylene oxide. It belongs to the alkyl ethoxylate family and is used to stabilize mixtures of oil and water in cosmetic formulations.
How it works
In a cosmetic product, PPG-2-Deceth-7 positions itself at the boundary between oil and water droplets, reducing surface tension so the two phases stay mixed. This creates a stable, uniform lotion or cream. In cleansers, it also helps break down sebum and dirt so they can be rinsed away without stripping the skin's natural moisture barrier excessively.
Pros
Gentle cleanser
PPG-2-Deceth-7 is a mild surfactant that cleans without stripping the skin's natural oils, making it suitable for daily use on normal to sensitive skin.
Stable emulsions
It helps keep oil and water mixed in creams and lotions, preventing separation and ensuring a consistent texture every time you use the product.
Cons and cautions
Synthetic origin
This ingredient is man-made and may not appeal to consumers who prefer naturally derived or organic skincare ingredients.
Potential for irritation at high levels
While generally mild, very high concentrations in leave-on products could cause slight irritation for extremely sensitive individuals.
Best for
- People with normal to combination skin looking for a gentle cleanser
- Those who use rinse-off products like shampoos and body washes
Use caution if
- Individuals seeking 100% natural or organic formulations
- Those with known sensitivity to ethoxylated ingredients (rare)
Usage tips
Safety summary
PPG-2-Deceth-7 is considered safe for use in cosmetics at typical concentrations. It is a mild surfactant with low irritation and comedogenic potential. As with any ingredient, individuals with known sensitivities should patch test.
Research notes
Research on PPG-2-Deceth-7 specifically is limited, but it belongs to a well-studied class of ethoxylated surfactants. The Cosmetic Ingredient Review has reviewed similar compounds and found them safe for cosmetic use when formulated properly.
Common label clues
- Typical concentration
- Typically 0.5–5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar ethoxylated surfactants and found them safe as used.
- Common uses
- Cleansers, Shampoos, Body washes, Emulsions
- Environmental note
- PPG-2-Deceth-7 is biodegradable and not expected to persist in the environment, though its production involves ethylene oxide, which requires careful industrial handling.
Good to know
- PPG-2-Deceth-7 is often used alongside other surfactants to reduce overall irritation potential.
- It is considered biodegradable and safe for aquatic environments at typical use levels.
