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-4 Trideceth-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-4 Trideceth-6 is a synthetic surfactant and emulsifier derived from propylene glycol and tridecyl alcohol. It belongs to the alkyl ether sulfate family and is designed to be gentle on skin while effectively removing oils.
How it works
In a cosmetic product, PPG-4 Trideceth-6 reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps lift sebum, makeup, and other oily impurities from the skin so they can be rinsed away with water.
Pros
Gentle cleansing
Effectively removes oil and makeup without stripping the skin's natural moisture barrier.
Low irritation risk
Rated as low-irritation in standard patch tests, making it suitable for most skin types.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a concern for consumers preferring natural or organic products.
Potential sensitivity
A small percentage of people with very reactive skin may experience mild redness or stinging.
Best for
- People with normal to oily skin
- Those looking for a gentle cleanser that still removes makeup and sunscreen
Use caution if
- Individuals with known sensitivity to propylene glycol derivatives
- Those seeking 100% natural formulations
Usage tips
Safety summary
PPG-4 Trideceth-6 is considered safe for use in cosmetics at typical concentrations. It has low acute toxicity and is not a known skin sensitizer. However, as with any surfactant, individuals with very sensitive skin should patch test first.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found PPG alkyl ethers to be safe when formulated appropriately. Limited peer-reviewed studies specifically on PPG-4 Trideceth-6 exist, but its chemical class is well-characterized.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. Subject to concentration limits in leave-on products in some regions.
