INCI: PEG-26 Jojoba Acid

A gentle, water-soluble cleanser derived from jojoba oil that helps remove dirt and makeup without stripping the skin.

In plain English

PEG-26 Jojoba Acid is a modified version of jojoba oil that has been made water-friendly. It acts as a mild soap-like ingredient that helps lift away oil, dirt, and makeup from your skin while rinsing off easily. Because it's derived from jojoba (a plant oil similar to skin's natural sebum), it tends to be less harsh than traditional sulfates.

Quick decision guide

Useful, but context matters

PEG-26 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PEG-26 Jojoba Acid.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic surfactant made by attaching polyethylene glycol (PEG) chains to jojoba acid, a fatty acid from jojoba oil. This process makes the oil-soluble jojoba acid water-soluble, allowing it to function as a gentle cleanser.

How it works

In a product, PEG-26 Jojoba Acid reduces the surface tension between water and oil, helping to break down sebum and makeup. Its mild amphiphilic structure allows it to surround and lift away impurities, which are then rinsed off with water.

Pros

Mild on skin

Unlike harsh sulfates, PEG-26 Jojoba Acid cleanses without stripping the skin's moisture barrier, making it suitable for daily use on sensitive or dry skin.

Plant-based origin

Derived from jojoba oil, a renewable plant source that closely mimics the skin's natural sebum, offering a more biocompatible cleansing experience.

Cons and cautions

Potential processing impurities

As a PEG derivative, there is a small risk of contamination with ethylene oxide or 1,4-dioxane during manufacturing, though reputable brands use purified grades to minimize this.

Limited heavy-duty cleansing

It may not fully remove long-wear or waterproof makeup in a single cleanse, often requiring a double-cleansing routine for complete removal.

Best for

  • People with dry or sensitive skin looking for a gentle cleanser
  • Those who prefer plant-derived cleansing ingredients over sulfates

Use caution if

  • Individuals with known allergies to jojoba or PEG derivatives (rare)

Usage tips

Use as part of a double-cleansing routine: follow with a water-based cleanser containing PEG-26 Jojoba Acid after an oil cleanser for thorough yet gentle makeup removal.

Safety summary

PEG-26 Jojoba Acid is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace impurities (ethylene oxide, 1,4-dioxane) in poorly manufactured PEG ingredients, but reputable suppliers and brands use purification steps to ensure safety. It is non-irritating and non-comedogenic for most skin types.

Research notes

While specific studies on PEG-26 Jojoba Acid are limited, the broader class of PEG-modified fatty acids and jojoba derivatives has been reviewed by the CIR panel and found safe. Jojoba oil itself is well-studied for its moisturizing and anti-inflammatory properties. The ingredient's mildness is supported by its chemical structure and anecdotal evidence from formulators.

Common label clues

Typical concentration
1–10% in rinse-off products; lower in leave-on formulas
Regulatory status
Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated PEG derivatives and found them safe when formulated according to guidelines.
Common uses
Cleansers, Facial washes, Makeup removers, Shampoos
Environmental note
Jojoba is a drought-resistant crop, making it a relatively sustainable plant source. However, the PEG modification process is synthetic and may have a moderate environmental footprint depending on manufacturing practices.

Good to know

  • PEG-26 Jojoba Acid is often used in sulfate-free cleansers to provide a creamy, non-stripping lather.
  • The '26' refers to the average number of ethylene glycol units attached, which influences its water solubility and mildness.
