Ingredient review
PPG-2 Hydroxyethyl Cocamide
INCI: PPG-2 HYDROXYETHYL COCAMIDE
A gentle, coconut-derived surfactant that helps create a rich lather and improve the feel of cleansers without stripping the skin.
In plain English
PPG-2 Hydroxyethyl Cocamide is a mild cleansing ingredient made from coconut oil. It helps shampoos and body washes foam up nicely and feel less harsh on your skin. Think of it as a helper that makes the main cleansers (like sulfates) gentler and more pleasant to use.

Quick decision guide
Useful, but context matters
PPG-2 Hydroxyethyl Cocamide 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 PPG-2 Hydroxyethyl Cocamide.
- 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 surfactant derived from coconut oil (cocamide) modified with propylene glycol (PPG) and hydroxyethyl groups. It is often used as a foam booster and viscosity builder in rinse-off personal care products.
How it works
It lowers the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. It also stabilizes foam and thickens the product formula, giving a richer, creamier lather that feels less drying than harsher surfactants.
Pros
Gentle on skin
PPG-2 Hydroxyethyl Cocamide is known for being milder than many traditional surfactants, making it a good choice for daily cleansers that won't strip the skin's natural moisture barrier.
Enhances product feel
It boosts foam and thickens the formula, giving shampoos and body washes a luxurious, creamy texture that many users find more satisfying and less runny.
Cons and cautions
Not fully natural
Although derived from coconut oil, it undergoes chemical modification, so it may not appeal to those seeking entirely natural or minimal-ingredient products.
Potential for mild irritation
While generally very gentle, a small percentage of people with extremely reactive skin may experience slight stinging or dryness, especially in high-concentration formulas.
Best for
- People with normal to dry skin looking for a gentle cleanser
- Anyone who enjoys a foamy, creamy lather without excessive dryness
Use caution if
- Those with known coconut oil allergies should check with a dermatologist before use
Usage tips
Safety summary
PPG-2 Hydroxyethyl Cocamide is considered safe for use in rinse-off cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with coconut allergies should exercise caution.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) and other bodies support the use of cocamide derivatives as mild surfactants. Direct studies on PPG-2 Hydroxyethyl Cocamide are limited, but its chemical class is well-established as low-risk.
Common label clues
- Typical concentration
- 1–5% in rinse-off formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated related cocamide ingredients and found them safe at typical use concentrations.
- Common uses
- Shampoos, Body washes, Facial cleansers, Foaming bath products
- Environmental note
- Derived from renewable coconut oil, but the chemical processing involves propylene glycol, which is petroleum-derived. It is generally considered biodegradable.
Good to know
- PPG-2 Hydroxyethyl Cocamide is often used as a replacement for DEA-based foam boosters, which have raised safety concerns.
- It is considered biodegradable and is commonly found in 'gentle' or 'daily care' product lines.
