Ingredient review
PEG-15 Jojoba Acid
INCI: PEG-15 Jojoba Acid
A gentle, semi-synthetic surfactant derived from jojoba oil that helps cleanse without stripping the skin.
In plain English
PEG-15 Jojoba Acid is a mild cleansing ingredient made by attaching a small chain of polyethylene glycol (PEG) to jojoba acid, which comes from jojoba oil. It helps water and oil mix together so that dirt and makeup can be rinsed away easily. Because it's derived from jojoba, it's considered gentler than many harsher detergents, making it a good choice for sensitive or dry skin types.

Quick decision guide
Useful, but context matters
PEG-15 Jojoba Acid 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 PEG-15 Jojoba Acid.
- 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
PEG-15 Jojoba Acid is a semi-synthetic compound created by reacting jojoba acid (a fatty acid from jojoba oil) with ethylene oxide to form a PEG (polyethylene glycol) derivative. It functions as a non-ionic surfactant and emulsifier, meaning it helps blend oil and water and reduces surface tension to lift away impurities.
How it works
In a cosmetic product, PEG-15 Jojoba Acid works by surrounding oil-based dirt and makeup with its water-loving (hydrophilic) head and oil-loving (lipophilic) tail. This allows the impurities to be suspended in water and rinsed away without stripping the skin's natural moisture barrier. Its mildness comes from the jojoba backbone, which is similar to the skin's own sebum.
Pros
Mild on skin
Because it's derived from jojoba oil, it cleanses without stripping the skin's natural oils, making it suitable for daily use on sensitive or dry skin.
Good emulsifier
It effectively blends oil and water, helping to remove makeup and sunscreen without leaving a greasy residue.
Cons and cautions
Manufacturing concerns
PEG compounds can be contaminated with 1,4-dioxane (a potential carcinogen) during production, though reputable manufacturers purify them to safe levels.
Not fully natural
Despite its jojoba origin, the PEG modification makes it semi-synthetic, which may not appeal to those seeking 100% natural or organic skincare.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who prefer sulfate-free cleansing options
Use caution if
- Individuals who strictly avoid any PEG-derived ingredients or prefer 100% natural products
Usage tips
Safety summary
PEG-15 Jojoba Acid is considered safe for use in cosmetics at typical concentrations. The main safety concern is potential contamination with 1,4-dioxane during manufacturing, but reputable brands ensure purification. It is generally non-irritating and non-comedogenic.
Research notes
Research on PEG-15 Jojoba Acid specifically is limited, but studies on PEG derivatives and jojoba-based ingredients support their safety and mildness. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe when used as intended.
Common label clues
- Typical concentration
- Typically 1–10% of the formula
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. Manufacturers are expected to follow good manufacturing practices to minimize impurities like 1,4-dioxane.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- Jojoba is a sustainable crop that requires little water, but the PEG process involves petrochemical-derived ethylene oxide, which has a higher environmental footprint than fully natural alternatives.
Good to know
- PEG-15 Jojoba Acid is often found in sulfate-free cleansers marketed for sensitive skin.
- The number '15' refers to the average length of the PEG chain, which affects its solubility and mildness.
