Jojoba Wax PEG-120 Esters
INCI: JOJOBA WAX PEG-120 ESTERS
A gentle, non-stripping emulsifier derived from jojoba wax that helps cleanse without drying out the skin.
In plain English
Jojoba Wax PEG-120 Esters is a modified version of jojoba oil that has been processed to work as an emulsifier—a helper ingredient that blends oil and water together in a product. In cleansers, it gently lifts dirt and makeup while leaving a light, non-greasy film that helps skin feel soft and hydrated, not tight or stripped.

Quick decision guide
Useful, but context matters
Jojoba Wax PEG-120 Esters 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 Jojoba Wax PEG-120 Esters.
- 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
A semi-synthetic ingredient made by reacting jojoba wax with polyethylene glycol (PEG). The result is a water-soluble wax that acts as a mild surfactant and emulsifier, commonly used in sulfate-free cleansers.
How it works
It reduces the surface tension between oil and water, allowing them to mix and rinse away impurities. Unlike harsher detergents, it forms a gentle micelle structure that cleans without disrupting the skin's natural moisture barrier.
Pros
Non-stripping cleanser
It removes dirt and makeup without leaving skin feeling tight or dry, making it ideal for dry or sensitive skin.
Conditioning feel
It leaves a light, moisturizing film on the skin after rinsing, which helps maintain comfort and softness.
Cons and cautions
Mild lather
It produces a low, creamy foam rather than big bubbles, which may not satisfy those who prefer a rich lather.
PEG processing concerns
As a PEG derivative, there is a theoretical risk of trace impurities like ethylene oxide, though reputable manufacturers use purified grades.
Best for
- People with dry or sensitive skin who find traditional cleansers too harsh
- Anyone looking for a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a very foamy, deep-cleansing lather may find it too mild
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. The PEG component is well-studied, and purified grades minimize any risk of impurities. Skin irritation and allergy are rare.
Research notes
Limited direct clinical studies on this specific ester, but it is widely used in cosmetic formulations as a mild alternative to harsher surfactants. Safety assessments of PEG derivatives support its low irritation profile.
Common label clues
- Typical concentration
- 1–5% in rinse-off products; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics globally; PEG compounds are regulated for purity by bodies like the FDA and EU CosIng.
- Common uses
- Cleansers, Facial washes, Body washes, Lotions, Creams
- Environmental note
- Jojoba is a sustainable crop grown in arid regions, but the PEG modification is a synthetic process. Biodegradability is moderate compared to pure plant-based surfactants.
Good to know
- Jojoba wax is actually a liquid ester, not a true oil, making it very similar to human sebum.
- This ingredient is often found in 'cream cleansers' and 'milk cleansers' for its gentle, non-foaming texture.
