At a glance
Four named levels, read from this ingredient’s chemical class, its charge, its solubility, or where it sits on the labels we have. More dots means more of the property named — never “better”.
How much of it is left on hair between washes.
What it takes to get it off the hair again.
How much easier it makes a comb pass.
How much the class is felt on fine hair.
| Property | Level | Out of |
|---|---|---|
| Buildup risk | Low | 2 of 5 |
| Rinse-out behaviour | Stays where hair is damaged | 2 of 5 |
| Slip | High | 5 of 5 |
| Weight | Noticeable | 4 of 5 |
What it does for a formula
What Bis-Aminopropyl Dimethicone does
The general function first, then how the role changes by product type where we have researched it.
Fills the gaps between lifted cuticle scales so light reflects evenly.
Lowers the drag a comb feels, which is most of what "detangling" means.
Included for feel and detangling rather than for cleaning or structure.
The film is what holds a shape once the water has gone.
Charge
Positively charged, so it is drawn to the negatively charged, damaged areas of hair and stays behind after rinsing. That is why conditioning happens where the wear is.
Solubility
Spreads through water without truly dissolving, and normal shampooing removes it.

How to read this
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order.
So position tells you about relative amount only above that line, and we never convert a position into a percentage.
Who should pay attention
Conditional formulation guidance, scoped to a hair condition and to the positions where it is meaningful. It is not a conclusion about any finished product, and not a conclusion about you.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Its charge concentrates it on the damaged sections of a strand, which is where combing friction and breakage are highest.
It deposits selectively rather than layer on layer, but it is still a silicone film, and ordinary shampooing may not remove all of it.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
Near the top of a list, a conditioning film adds weight that fine hair loses volume to.
Read where it is listed in the first three ingredients or positions 4–8.Read from this ingredient’s chemical class. Where we have researched the ingredient itself, that reading replaces the class one.
Why it matters to shoppers
What this ingredient is evidence of, what it is not evidence of, and what our own method can and cannot tell you.
- slip and surface smoothing
- easier combing
- a style that holds
- a product ordinary shampooing removes
- an exact safety score — we do not publish one, for any ingredient
- how a finished product performs by itself — that is the whole formula, not one line of it
- the exact percentage in a bottle — label position never converts into a number
- a supporting silicone alongside the main ingredients in our conditioners
- it was on the label of every product we counted — we read printed ingredient lists, not marketing copy
- it is meant to stay on the hair rather than rinse away
- buildup — the water-soluble ones rinse out with ordinary shampoo
- that a product is right or wrong for you
We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.
Why some people avoid it
A conditioning agent that lays a smooth film on the cuticle, which is what delivers slip, shine and frizz control.
The water-insoluble ones need a detergent wash to remove, so on a routine that avoids detergent they accumulate and can leave hair feeling coated. That is the curly-method objection, and it is about buildup rather than harm. Water-soluble silicones rinse out and do not raise it.
Where regulators stand: Permitted. Some cyclic silicones are restricted in the EU on environmental grounds — persistence in waterways — rather than for anything to do with skin.

These ingredients tend to appear together to carry the formula and let it dry, soften the strand, and keep the formula stable.

How this page was made
- Every number above is counted from the ingredient lists in our own product library — 47 of 3889 researched products list this ingredient. Nothing on this page is written per ingredient.
- The dots are named levels read from an ingredient’s chemical class, charge, solubility, or where it sits on the labels we have — never a score.
- US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Position tells you about relative amount only above that line, and we never convert a position into a percentage.
- The prominence bands (leading, supporting, secondary) are the same ones the product pages use to read a single label, applied here to the median position across a category.
- We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.
- Identifiers and references appear only when a published source is attached to this entry; where none is, the row is simply absent rather than filled in.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
