Ingredient review
PEG-8 Tucuma Oil Esters
INCI: ASTROCARYUM VULGARE OIL PEG-8 ESTERS
A gentle, water-friendly emollient that helps cleansers feel moisturizing without stripping the skin.
In plain English
This ingredient is a modified oil from the tucuma palm fruit. The original oil is rich in fatty acids, but it's been chemically combined with a small PEG (polyethylene glycol) chain to make it mix easily with water. This means it can be used in cleansers and body washes to add a soft, smooth feel without leaving a greasy residue. It's a mild surfactant that helps remove dirt and oil while keeping the skin's natural moisture barrier intact.

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 ester created by reacting tucuma (Astrocaryum vulgare) palm oil with PEG-8. The result is a water-soluble emollient that functions as a gentle cleansing agent and skin conditioner.
How it works
In a cosmetic product, this ingredient acts as a mild surfactant and emollient. Its PEG-modified structure allows it to dissolve in water while still carrying the fatty acids from the tucuma oil. When you wash, it helps lift dirt and excess oil from the skin, then rinses away cleanly, leaving behind a thin, non-greasy film that softens and smooths the skin.
Pros
Gentle on skin
This ingredient cleanses without disrupting the skin's natural moisture barrier, making it suitable for daily use even on sensitive skin.
Improves rinse-off feel
It helps cleansers rinse away cleanly while leaving a soft, smooth after-feel, reducing the need for heavy moisturizers post-wash.
Cons and cautions
Semi-synthetic origin
Because it contains PEG, it is not a fully natural ingredient, which may be a concern for those seeking plant-only formulations.
Potential for trace impurities
Manufacturing impurities in PEG compounds are possible, though high-quality cosmetic grades are purified to safe levels.
Best for
- People with normal to dry skin who want a non-stripping cleanser
- Anyone looking for a gentle, everyday body wash or facial cleanser
Use caution if
- Individuals with known sensitivity to PEG compounds (rare)
- Those seeking a completely natural or PEG-free skincare routine
Usage tips
Safety summary

The main safety consideration is the potential for trace impurities in PEG manufacturing, but reputable suppliers use purified grades that meet regulatory standards. Irritation and allergy risks are low.
Research notes
There is limited direct research on this specific ester, but studies on PEG-modified oils and tucuma oil individually support its safety and efficacy as a mild surfactant and emollient. The CIR panel has reviewed PEG compounds broadly and found them safe in cosmetics.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. The Cosmetic Ingredient Review (CIR) panel has deemed PEG compounds safe as used in cosmetics when manufactured to purity standards.
- Common uses
- Cleansers, Body washes, Shampoos, Facial cleansers
- Environmental note
- Tucuma palm is a sustainable crop in the Amazon region, but the PEG modification is a synthetic process. Biodegradability is moderate; check product-specific environmental claims.
Good to know
- Tucuma oil is traditionally used in South America for its moisturizing properties.
- PEG-8 is a short-chain PEG, which is generally considered safer and less likely to cause irritation than longer-chain PEGs.
