Ingredient review
PPG-2-Isodeceth-10
INCI: PPG-2-ISODECETH-10
A mild synthetic emulsifier that helps mix oil and water in cleansers and shampoos, generally well-tolerated by most skin types.
In plain English
PPG-2-Isodeceth-10 is a man-made ingredient that helps oil and water blend together in a product. You'll find it in cleansers, shampoos, and body washes to create a smooth, even texture. It's considered very mild and unlikely to cause irritation or clog pores, making it a safe choice for most people.

Quick decision guide
Useful, but context matters
PPG-2-Isodeceth-10 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-Isodeceth-10.
- 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-Isodeceth-10 is a synthetic surfactant and emulsifier derived from propylene glycol and isodecyl alcohol, processed with ethylene oxide. It belongs to a class of ingredients called alkoxylated alcohols, which are widely used in cosmetics for their ability to reduce surface tension and stabilize mixtures.
How it works
In a cosmetic product, PPG-2-Isodeceth-10 works by lowering the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps the product spread evenly, rinse off cleanly, and deliver other ingredients effectively. It also helps create a rich lather in cleansers and shampoos.
Pros
Gentle on skin
Rated low on irritation and comedogenic scales, so it's unlikely to cause breakouts or stinging, even for sensitive skin.
Improves product feel
Helps cleansers and shampoos rinse off cleanly without leaving a greasy or sticky residue.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for those seeking plant-based or 'clean' beauty products.
Ethoxylation concerns
The manufacturing process can create trace amounts of 1,4-dioxane, a potential contaminant, though reputable brands keep levels well below safety limits.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Anyone using rinse-off products like shampoo or body wash
Use caution if
- Those who strictly avoid all synthetic or ethoxylated ingredients
Usage tips
Safety summary
PPG-2-Isodeceth-10 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. The main concern is trace 1,4-dioxane from ethoxylation, but regulatory limits and purification steps keep levels safe.
Research notes
There is limited direct research on PPG-2-Isodeceth-10 specifically, but it is structurally similar to other alkoxylated alcohols that have been reviewed by the Cosmetic Ingredient Review panel and found safe. No significant adverse effects have been reported in cosmetic use.
Common label clues
- Typical concentration
- Usually under 5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar ethoxylated alcohols and found them safe at typical use levels.
- Common uses
- Cleansers, Shampoos, Conditioners, Body washes
- Environmental note
- As a synthetic surfactant, it may not be readily biodegradable. However, it is used in low concentrations and is typically rinsed off, limiting environmental exposure.
Good to know
- PPG-2-Isodeceth-10 is often used alongside other surfactants to reduce overall irritation.
- It is not a fragrance or preservative, so it won't affect the scent or shelf life of a product.
