Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.

Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.

Production[edit]

This TiO2 manufacturer mainly produces R5566, R5567, R5568, R5569 and other series products, which are used in coatings, plastics, papermaking, ink and other fields.

One of the key responsibilities of titanium dioxide manufacturers is to produce high-quality products that meet the stringent requirements of their customers. This involves carefully sourcing raw materials, employing efficient production processes, and conducting rigorous quality control measures to ensure that the final product meets the necessary specifications.
