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 oil the solid takes up.
A solid at room temperature holds hair where it is put.
| Property | Level | Out of |
|---|---|---|
| Buildup risk | Needs a real cleanser | 5 of 5 |
| Rinse-out behaviour | Removed mechanically | 1 of 5 |
| Absorbency | None | 1 of 5 |
| Grip | None | 1 of 5 |
What it does for a formula
What Titanium Dioxide does
The general function first, then how the role changes by product type where we have researched it.
Purely how the product looks in the bottle.
A solid particle: it changes how a formula looks and feels, not what it cleans.
The colour of what is in the bottle — or, in a depositing product, of the hair.
It dissolves in neither water nor oil, so it is removed by washing or brushing.
Charge
Charge is not recorded for this ingredient.
Solubility
Does not dissolve in water or oil. It sits on the surface and is removed mechanically or by cleansing.

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 violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.
A deposited colorant is a surface layer. It is a very small amount of material, but on a routine already fighting for root lift it is one more thing sitting on the strand.
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.
- a creamy-looking product
- body and opacity
- a product whose colour you can see
- a visible surface effect
- an exact safety score — we do not publish one, for any ingredient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 secondary opacifier, listed below the main ingredients in our shampoos
- it was on the label of every product we counted — we read printed ingredient lists, not marketing copy
- a treatment effect — it changes how the formula looks and feels
- that it will change your hair colour
- 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.

The number beside a name is how many products in our library list both.
These ingredients tend to appear together to absorb oil and add texture, keep the formula stable, and improve feel after rinsing.

How this page was made
- Every number above is counted from the ingredient lists in our own product library — 68 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.
