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 fast it leaves after the product is applied.
What is still on the hair once it has evaporated.

What it does for a formula
What Diisopropyl Adipate does
The general function first, then how the role changes by product type where we have researched it.
What everything else is dissolved in before it reaches your hair.
A light, fast-spreading lipid used where an oil would feel heavy.
Smooths the feel of the strand without adding hold or cleaning.
It takes a surfactant to remove — worth knowing on a low-detergent routine.
Charge
Charge is not recorded for this ingredient.
Solubility
Needs a surfactant to remove. On a low-detergent routine it can build up over time.

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 light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
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.
- softness without weight
- a light, fast-drying formula
- a softer feel
- something that lasts through the day
- an exact safety score — we do not publish one, for any ingredient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 primary solvent near the top of the ingredient list in our heat protectants
- it was on the label of every product we counted — we read printed ingredient lists, not marketing copy
- 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We do not publish safety scores or hazard grades.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.

How this page was made
- Every number above is counted from the ingredient lists in our own product library — 9 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.
- Entry last updated 2026-08-28. Product-page methodology: the product library.
