PPG-2-Deceth-15
INCI: PPG-2-Deceth-15
A gentle synthetic emulsifier that helps cleansers and lotions mix oil and water without stripping the skin.
In plain English
PPG-2-Deceth-15 is a man-made ingredient that helps oil and water stay blended in products like cleansers and makeup removers. It's considered mild and is often used in formulas that need to remove makeup or sunscreen without leaving a greasy residue. Think of it as a helper that keeps your product smooth and effective.

Quick decision guide
Useful, but context matters
PPG-2-Deceth-15 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-15.
- 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
A synthetic surfactant and emulsifier derived from decyl alcohol and ethylene oxide/propylene oxide. It belongs to the alkyl ether sulfate family and is designed to be gentle on skin while still effectively mixing oil and water phases.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. In a cleanser, it helps lift dirt, oil, and makeup from the skin so they can be rinsed away. Its mildness comes from its large molecular structure, which makes it less likely to penetrate the skin barrier.
Pros
Gentle on skin
Its large molecular structure means it stays on the surface and doesn't strip the skin's natural oils, making it suitable for daily use.
Effective emulsifier
It helps oil and water mix well, so your cleanser or lotion stays smooth and works consistently from first use to last.
Cons and cautions
Synthetic origin
It is made through chemical processing, which may not align with preferences for naturally derived ingredients.
Potential for irritation at high levels
While generally mild, very high concentrations (above 5%) could cause slight stinging or redness in sensitive individuals.
Best for
- People with normal to combination skin
- Those looking for a gentle makeup remover or daily cleanser
Use caution if
- Individuals with known sensitivities to ethoxylated ingredients (rare)
- Those strictly avoiding all synthetic ingredients
Usage tips
Safety summary
PPG-2-Deceth-15 is considered safe for use in cosmetics at typical concentrations. It is low in irritation and comedogenicity, making it suitable for most skin types. As with any surfactant, avoid contact with eyes and discontinue use if irritation occurs.
Research notes
Research on alkyl ether sulfates like PPG-2-Deceth-15 indicates they are mild surfactants with low skin penetration. The Cosmetic Ingredient Review has assessed similar ingredients and found them safe for cosmetic use. No specific long-term human studies are available for this exact compound, but its chemical class is well-studied.
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 most major markets. The Cosmetic Ingredient Review (CIR) panel has reviewed similar alkyl ether sulfates and found them safe at typical use levels.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- Synthetic but biodegradable; production involves ethylene oxide, which has environmental considerations in manufacturing.
Good to know
- PPG-2-Deceth-15 is considered biodegradable under standard conditions.
- It is often used in 'micellar water' style cleansers for its gentle cleansing power.
