Ingredient review
PPG-5 C12-14 Sec-Pareth-9
INCI: PPG-5 C12-14 Sec-Pareth-9
A synthetic cleansing agent that effectively removes oil and dirt but may be drying or irritating for sensitive skin.
In plain English
This ingredient is a man-made surfactant, which means it helps water mix with oil and dirt so they can be rinsed away. It's often used in cleansers and shampoos to create a foamy lather and leave skin feeling clean. Because it can be strong, it might strip natural oils if used too often, especially on dry or sensitive skin.

Quick decision guide
Useful, but context matters
PPG-5 C12-14 Sec-Pareth-9 can be useful, but watch for some irritation potential.
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-5 C12-14 Sec-Pareth-9.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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 ethoxylated surfactant derived from petroleum. The 'PPG-5' part indicates a propylene glycol chain that helps control how the ingredient interacts with water and oil, while 'C12-14 Sec-Pareth-9' refers to a secondary alcohol ethoxylate with a specific chain length and degree of ethoxylation.
How it works
It reduces the surface tension between water and oil, allowing oily impurities on the skin to be lifted and suspended in water so they can be rinsed away. This makes it effective at removing makeup, sunscreen, and excess sebum.
Pros
Strong cleanser
Effectively breaks down and removes oil-based impurities, makeup, and sunscreen, leaving skin feeling thoroughly clean.
Good lather
Produces a rich foam that many people associate with a satisfying cleansing experience, making it popular in shampoos and body washes.
Cons and cautions
Potential for dryness
Can strip the skin of its natural oils, leading to tightness, flakiness, or irritation, especially with frequent use on dry or sensitive skin.
Ethoxylation concerns
As an ethoxylated ingredient, it may contain trace amounts of 1,4-dioxane, a potential carcinogen, though levels are typically low in well-manufactured products.
Best for
- People with oily or combination skin looking for a deep cleanse
- Those who wear heavy makeup or sunscreen and need thorough removal
Use caution if
- Individuals with very dry, sensitive, or compromised skin barriers
- Those who prefer entirely plant-derived or non-ethoxylated surfactants
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. The main concerns are potential skin dryness and irritation, especially for sensitive skin types, and trace contamination with 1,4-dioxane. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have reviewed similar ethoxylated surfactants and found them safe when formulated properly.
Research notes
Studies on similar ethoxylated surfactants indicate they are effective cleansers but can disrupt the skin barrier with frequent use. Research on 1,4-dioxane contamination shows that levels in cosmetics are generally low but can be reduced through purification. More specific studies on PPG-5 C12-14 Sec-Pareth-9 are limited, but its safety profile is consistent with related compounds.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits typically set by industry guidelines. Manufacturers are encouraged to minimize 1,4-dioxane contamination.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- Synthetic and petroleum-derived; not readily biodegradable in all conditions. Some ethoxylated surfactants can be persistent in aquatic environments.
Good to know
- This ingredient is often found in combination with other milder surfactants to balance cleansing power with gentleness.
- The 'Sec-Pareth' designation indicates it is a secondary alcohol ethoxylate, which can be slightly less irritating than primary alcohol ethoxylates.
