- Step 1Start with the score, then check the irritation and clogging risk before judging PPG-12 Capryleth-18.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 (surface-active agent) derived from caprylic alcohol and ethylene oxide, modified with propylene glycol. It is part of the capryleth family, known for mild cleansing and emulsifying properties.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable emulsion. In a cleanser, it surrounds dirt and oil particles so they can be rinsed away with water. It also helps other ingredients spread evenly across the skin or hair.
Pros
Mild cleansing action
It cleans effectively without stripping the skin's natural moisture barrier as harshly as some sulfates.
Improves product texture
It helps creams and lotions feel smooth and spread easily, enhancing the user experience.
Cons and cautions
Potential for dryness
In high concentrations or with frequent use, it may leave very dry or sensitive skin feeling tight or irritated.
Synthetic origin
It is not naturally derived, which may be a drawback for consumers seeking plant-based or minimal-ingredient formulas.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Anyone using rinse-off products like shampoos or body washes
Use caution if
- Those with extremely dry or compromised skin barriers who prefer non-surfactant cleansers
