INCI Name for Titanium Dioxide Dispersion

Asked by: juron66 On: January 07, 2023 Product Type: Cosmetics

Question

What is the correct INCI name for "Titanium Dioxide Transparent (15nm, Water-Dispersion)"? I saw information listing it as 10-Hydroxydecanoic Acid, which seems incorrect as that's the INCI for Royal Jelly.

Answer

Based on the product description for "Titanium Dioxide Transparent (15nm, Water-Dispersion)", the INCI name is indeed different from 10-Hydroxydecanoic Acid.

The correct INCI name listed for "Titanium Dioxide Transparent (15nm, Water-Dispersion)" is:
Titanium Dioxide, Ammonium Polyacrylate, Water, Butylene Glycol, Hydrated Silica

This INCI name reflects the composition of the product, which is a dispersion containing Titanium Dioxide along with other ingredients that help it disperse in water.

It appears there might have been an error in the information you saw previously regarding the INCI name being 10-Hydroxydecanoic Acid for this specific product.

If I use this sunscreen at 10% in my formulation, do I need to break down the percentages of the individual sub-components (the ingredients that come with it) when filing for FDA (อย.) registration?

Answer:

When registering a cosmetic product with the FDA (อย.) using Titanium Dioxide Transparent (15nm, Water-Dispersion), you must separate and calculate the percentage of each individual component in your final formula.

The FDA registration system requires the full INCI list of the final product, with each ingredient's actual concentration in the total formulation. You cannot list the raw material as a single item.

Calculation Example

If you use Titanium Dioxide Transparent (15nm, Water-Dispersion) at 10% in your formula, you need to break it down based on its composition (which contains 28% Titanium Dioxide):

Titanium Dioxide: 10% (usage) × 28% (concentration in raw material) = 2.8% in the final formula.
Other Ingredients: The remaining 72% of the raw material consists of Ammonium Polyacrylate, Water, Butylene Glycol, and Hydrated Silica. You must calculate their respective weights based on the technical data sheet (COA/MSDS) or list them as part of the remaining 7.2% of your formula.

Summary for FDA Submission:

In the FDA System: You must enter each INCI name separately with its specific percentage in the final product.
On the Product Label: You list the ingredients in descending order of their concentration (from most to least).

For this specific product, the INCI breakdown is: Titanium Dioxide, Ammonium Polyacrylate, Water, Butylene Glycol, Hydrated Silica. You will need to input each of these into the registration system.
