Ingredient review
PPG-2 Cocamide
INCI: PPG-2 Cocamide
PPG-2 Cocamide helps cleansers foam and mix oil with water, but it can be drying or irritating for sensitive skin types.
In plain English
PPG-2 Cocamide is a helper ingredient in cleansers and shampoos. It makes the product foam up nicely and helps oil and water blend together so dirt and makeup rinse away. It is made from coconut oil but processed with chemicals, so it is not a natural ingredient. While it works well for normal skin, it can strip moisture or cause irritation if your skin is dry or sensitive.

Quick decision guide
Useful, but context matters
PPG-2 Cocamide can be useful, but watch for some irritation potential.
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 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
PPG-2 Cocamide is a semi-synthetic surfactant created by reacting coconut oil fatty acids with propylene glycol. It belongs to a group of ingredients called alkanolamides, which are known for boosting foam and stabilizing formulas.
How it works
In a cosmetic product, PPG-2 Cocamide sits at the boundary between oil and water molecules, reducing surface tension. This allows the product to spread easily, lift dirt and oil from the skin or hair, and create a rich lather that rinses cleanly.
Pros
Boosts lather
Creates a rich, stable foam that makes cleansing feel satisfying and effective.
Stabilizes formulas
Helps keep oil and water mixed together, so the product stays smooth and doesn't separate.
Cons and cautions
Can be drying
May strip natural oils from the skin, leading to tightness or flakiness, especially for dry skin types.
Irritation potential
In high concentrations or with frequent use, it can cause redness or stinging on sensitive skin.
Best for
- People with normal to oily skin who enjoy a foamy cleanser
- Those using rinse-off products like shampoo or body wash
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
- Anyone looking for a completely natural or plant-based routine
Usage tips
Safety summary
PPG-2 Cocamide is generally safe for most people when used in rinse-off cleansers. However, it can be drying or irritating for sensitive or dry skin. Avoid prolonged contact with eyes and do not use on broken skin.
Research notes
Research on PPG-2 Cocamide specifically is limited, but studies on similar alkanolamides indicate low acute toxicity and skin irritation at typical use levels. The Cosmetic Ingredient Review has deemed related ingredients safe for rinse-off use.
Common label clues
- Typical concentration
- Typically 0.5% to 5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar alkanolamides and found them safe in rinse-off products at concentrations up to 10%.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- PPG-2 Cocamide is semi-synthetic and may not be fully biodegradable. It is derived from coconut oil, a renewable resource, but the chemical processing adds environmental impact.
Good to know
- PPG-2 Cocamide is often used alongside other mild surfactants to reduce irritation.
- It is considered safe in rinse-off products by major regulatory bodies at typical use levels.
