INCI: PEG-75 MEADOWFOAM OIL
A gentle, water-soluble emollient that adds softness without greasiness, ideal for rinse-off products.

Quick decision guide
Useful, but context matters

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-75 Meadowfoam Oil.
- 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 created by attaching polyethylene glycol (PEG) chains to meadowfoam seed oil, making the oil water-dispersible while retaining its emollient properties.
How it works
In a product, it reduces surface tension so water and oil mix better, allowing the formula to spread smoothly. It also deposits a thin, non-greasy film on skin or hair that locks in moisture and reduces friction.
Pros
Water-soluble softness
Delivers the conditioning benefits of meadowfoam oil in a form that rinses cleanly, leaving no heavy residue.
Gentle cleanser
Acts as a mild surfactant that cleans without stripping the skin's natural moisture barrier, making it suitable for daily use.
Cons and cautions
PEG-related impurities
During manufacturing, trace amounts of ethylene oxide or 1,4-dioxane can form, though reputable brands purify to safe levels.
Not for water-free products
Because it is water-soluble, it won't work in oil-only or anhydrous formulations where water is absent.
Best for
- People with normal to dry skin looking for gentle cleansing
- Those who want a soft, conditioned feel from rinse-off products
Use caution if
- Individuals with known sensitivity to PEG compounds
- Those seeking completely natural or PEG-free formulations
Usage tips
Safety summary
PEG-75 Meadowfoam Oil is considered safe for cosmetic use at typical concentrations. The main concern is potential trace impurities from PEG manufacturing, but these are tightly regulated and minimized by quality suppliers.
Research notes
Studies on PEG compounds show low irritation and sensitization potential. Meadowfoam oil itself has been researched for its high oxidative stability and emollient properties. Combined, the ingredient is well-tolerated in rinse-off formulations.
Common label clues
- Typical concentration
- 1-10%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. PEG compounds are generally recognized as safe when used as directed.
- Common uses
- Cleansers, Shampoos, Conditioners, Body washes, Lotions
- Environmental note
- Meadowfoam is a sustainable crop grown primarily in the Pacific Northwest. The PEG modification process is synthetic, but the base oil is renewable.
Good to know
- Meadowfoam oil is naturally very stable and resistant to oxidation, so PEG-75 Meadowfoam Oil has a long shelf life.
- It is often used as a replacement for silicone-based conditioners in 'silicone-free' formulas.
