Ingredient review
PEG-3 Rapeseed Aminopropylamine
INCI: PEG-3 RAPESEED AMINOPROPYLAMINE
A conditioning ingredient that can improve softness and manageability, but may be irritating or clog pores for some.
In plain English
PEG-3 Rapeseed Aminopropylamine is a semi-synthetic ingredient made by combining rapeseed (canola) oil with a small PEG chain and an amine group. In hair products, it helps detangle and soften hair by coating the strands. In skincare, it can improve the feel of a product but may cause irritation or breakouts in sensitive or acne-prone individuals.

Quick decision guide
Useful, but context matters
PEG-3 Rapeseed Aminopropylamine can be useful, but watch for some irritation potential and possible clogging concerns.
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-3 Rapeseed Aminopropylamine.
- 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
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A conditioning surfactant and emulsifier derived from rapeseed oil, modified with a PEG (polyethylene glycol) chain and an amine group to improve its water solubility and conditioning properties.
How it works
The molecule has a fatty part that binds to hair or skin, and a water-loving part that helps it rinse off easily. This leaves a thin, conditioning film that reduces friction, making hair easier to comb and skin feel smoother.
Pros
Effective detangler
Reduces combing friction and leaves hair feeling smoother and more manageable, especially for dry or damaged hair.
Lightweight feel
Compared to heavier oils, it can provide conditioning without weighing hair down, making it suitable for finer hair types.
Cons and cautions
Potential irritant
The amine group can be irritating to sensitive skin or scalp, especially at higher concentrations or with frequent use.
Comedogenic risk
May clog pores for some individuals, leading to breakouts on the face, back, or chest if used in leave-on products.
Best for
- Those with dry or damaged hair seeking extra conditioning
- People with normal to oily hair who want lightweight detangling
Use caution if
- Individuals with very sensitive or eczema-prone skin
- Those with acne-prone skin who notice breakouts from conditioning ingredients
Usage tips
Safety summary
Generally considered safe in rinse-off products at typical concentrations. However, the amine group can cause irritation in sensitive individuals, and PEG impurities (like 1,4-dioxane) are a concern if not properly purified. Regulatory bodies set limits to minimize these risks.
Research notes
Limited peer-reviewed studies specifically on PEG-3 Rapeseed Aminopropylamine. Safety assessments rely on analog data from similar quaternary ammonium compounds and PEG derivatives, which show low acute toxicity but potential for skin irritation at high doses.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, subject to concentration limits and purity requirements for PEG compounds.
- Common uses
- Conditioners, Shampoos, Hair masks, Leave-in treatments
- Environmental note
- Rapeseed is a widely cultivated crop, but PEG compounds are derived from petroleum, making this a semi-synthetic ingredient with moderate environmental footprint.
Good to know
- Rapeseed oil is also known as canola oil, a common food oil.
- The 'PEG-3' part means it has a short polyethylene glycol chain, which helps the ingredient mix with water.
