Bisamino PEG/PPG-41/3 Aminoethyl PG-Propyl Dimethicone
INCI: BISAMINO PEG/PPG-41/3 AMINOETHYL PG-PROPYL DIMETHICONE
A gentle silicone that smooths hair and skin without heavy buildup, but may not suit those avoiding silicones.
In plain English
This is a type of silicone that has been modified with amino groups to make it more compatible with hair and skin. It forms a thin, flexible film that reduces frizz, adds shine, and makes the skin feel silky. Unlike some older silicones, it is designed to be less likely to cause buildup and is easier to wash out.

Quick decision guide
Useful, but context matters
Bisamino PEG/PPG-41/3 Aminoethyl PG-Propyl Dimethicone 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 Bisamino PEG/PPG-41/3 Aminoethyl PG-Propyl Dimethicone.
- 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 synthetic silicone polymer with amino (amine) groups attached, which helps it bind to negatively charged hair and skin surfaces for better conditioning.
How it works
The amino groups in the molecule are positively charged, so they stick to the negatively charged surface of damaged hair or skin. This creates an even, thin film that smooths the cuticle, reduces friction, and locks in moisture. The PEG/PPG chains make it water-dispersible, so it rinses out more easily than some other silicones.
Pros
Excellent detangling
Helps hair slide through combs easily, reducing breakage during styling.
Lightweight feel
Leaves hair and skin feeling soft and smooth without a heavy or greasy residue.
Cons and cautions
Synthetic ingredient
Not biodegradable and derived from petrochemicals, which may be a concern for eco-conscious users.
Potential buildup over time
Even though it's more water-dispersible, frequent use without proper cleansing can still lead to some accumulation on hair.
Best for
- People with dry, damaged, or frizzy hair looking for smoothing and shine
- Those who want a lightweight conditioner that doesn't weigh hair down
Use caution if
- Individuals strictly avoiding all silicones (e.g., for certain hair care routines like the Curly Girl Method)
Usage tips
Safety summary
Generally recognized as safe for topical use at typical cosmetic concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic use.
Research notes
Amino-functional silicones are well-studied for hair conditioning. They improve wet combing, reduce frizz, and add shine. Safety data supports low irritation and sensitization potential.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. No specific restrictions at typical use levels.
- Common uses
- Hair conditioners, Leave-in treatments, Shampoos, Skin lotions, Makeup primers
- Environmental note
- As a silicone, it is not readily biodegradable. However, its water-dispersible nature may reduce persistence compared to some other silicones.
Good to know
- This ingredient is often listed near the middle or end of an ingredient list, indicating moderate concentration.
- It is considered safer and more modern than some older silicones like dimethicone because it is more water-dispersible.
