PPG-8-Deceth-6
INCI: PPG-8-Deceth-6
A mild synthetic surfactant that helps products foam and rinse cleanly, generally well-tolerated but not a star active ingredient.
In plain English
PPG-8-Deceth-6 is a man-made ingredient that helps water and oil mix together in a product. It is often used in cleansers and shampoos to create a nice lather and to help rinse away dirt and makeup without leaving a greasy film. Think of it as a helper that makes the formula feel smooth and spread easily on your skin or hair.

Quick decision guide
Useful, but context matters
PPG-8-Deceth-6 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-8-Deceth-6.
- 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-8-Deceth-6 is a synthetic surfactant (a type of detergent) made from propylene glycol and decyl alcohol, with a specific chain length that makes it effective at lowering surface tension between oil and water. It is a clear, liquid ingredient commonly used in rinse-off products.
How it works
In a cosmetic product, PPG-8-Deceth-6 works by surrounding oil droplets and allowing them to be suspended in water, so they can be rinsed away. It also helps create foam and improves the spreadability of the formula on skin or hair, making cleansing feel more efficient and pleasant.
Pros
Gentle cleansing
PPG-8-Deceth-6 is considered a mild surfactant, making it suitable for daily use in cleansers and shampoos without stripping the skin's natural moisture barrier.
Good rinsability
It helps products rinse off cleanly, reducing the chance of leaving a sticky or greasy residue on skin or hair.
Cons and cautions
Not a functional active
This ingredient is purely a formulation helper; it does not provide hydration, anti-aging, or other skin benefits on its own.
Potential for dryness at high levels
In very high concentrations, it may contribute to slight dryness, especially for those with already dry or sensitive skin.
Best for
- People who use foaming cleansers or shampoos
- Those looking for a gentle, non-irritating surfactant in rinse-off products
Use caution if
- Individuals with extremely dry or compromised skin who prefer non-foaming cleansers
Usage tips
Safety summary
PPG-8-Deceth-6 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it a reliable choice for mild cleansing formulas. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on PPG-8-Deceth-6 specifically is limited, but the broader class of PPG and deceth surfactants has been evaluated by the Cosmetic Ingredient Review panel and found safe. Studies show these ingredients are mild to the skin and eyes when used in rinse-off products.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PPG and deceth compounds and found them safe as used.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- As a synthetic surfactant, it is not biodegradable as quickly as some natural alternatives, but it is generally considered low in aquatic toxicity at typical use levels.
Good to know
- PPG-8-Deceth-6 is often found in combination with other surfactants to balance foam and mildness.
- It is not a common standalone ingredient; you'll usually see it listed near the middle of an ingredient list.
