PPG-13 Decyltetradeceth-24
INCI: PPG-13 DECYLTETRADECETH-24
A reliable synthetic emulsifier that helps create smooth, stable lotions and creams with a pleasant feel.
In plain English
This ingredient is a man-made molecule that helps oil and water mix together in your skincare products. Without emulsifiers like this one, your lotion would separate into watery and oily layers. It also helps other ingredients spread evenly on your skin and can make the product feel silky or lightweight.

Quick decision guide
Useful, but context matters
PPG-13 Decyltetradeceth-24 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-13 Decyltetradeceth-24.
- 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-13 Decyltetradeceth-24 is a synthetic polymer surfactant, meaning it has both water-loving and oil-loving parts. It is created by reacting propylene glycol (PPG) and ethylene oxide (the 'eth' part) with a fatty alcohol chain. This structure allows it to stabilize mixtures of oil and water.
How it works
In a cosmetic formula, this molecule positions itself at the boundary between oil and water droplets, reducing surface tension so they blend into a stable emulsion. It also helps lower the surface tension of water, making it easier for the product to spread and for other ingredients to penetrate the skin's surface.
Pros
Stable emulsions
Helps keep oil and water mixed so your product stays smooth and effective from first use to last.
Improved texture
Contributes to a silky, non-greasy feel that makes moisturizers and sunscreens more pleasant to apply.
Cons and cautions
Synthetic origin
Made from petrochemicals, which may be a concern if you prefer plant-based or naturally derived ingredients.
Potential mild irritation
In rare cases, high concentrations can cause slight stinging or redness on very sensitive or compromised skin.
Best for
- Anyone using lotions, creams, or sunscreens that need a stable, non-separating texture
- People who prefer lightweight, fast-absorbing formulas
Use caution if
- Those with known sensitivity to PEG or PPG compounds (rare)
Usage tips
Safety summary
PPG-13 Decyltetradeceth-24 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with extreme sensitivity to synthetic surfactants may want to patch test.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel and other bodies have found PPG alkyl ethers like this one to be safe in rinse-off and leave-on products at concentrations up to 10%. No significant toxicity or sensitization has been reported.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Cleansers, Sunscreens, Serums
- Environmental note
- As a synthetic polymer, it is not biodegradable and may persist in the environment. However, it is used in very small amounts per product.
Good to know
- PPG-13 Decyltetradeceth-24 is considered safe for use in cosmetics by major regulatory bodies when used as directed.
- It is often combined with other emulsifiers to create a more robust formula.
