- Colloidal silicon dioxide, commonly known as silica, is a versatile and widely used material in various industries. It is a finely divided form of silica that is suspended in a liquid medium. The term colloidal refers to the particles being small enough to remain suspended rather than settling at the bottom of a solution.
Although cosmetics are not meant for consumption, there are concerns that titanium dioxide in lipstick and toothpaste may be swallowed or absorbed through the skin.

- Lithopone 28-30%, also known as B301 and B311, is a white pigment that has been widely used in various industries due to its excellent properties such as high brightness, good weather resistance, and chemical stability. This pigment is primarily composed of zinc sulfide (ZnS) and barium sulfate (BaSO4), which are combined in a specific ratio to achieve the desired color and performance.

PRINCIPALES UTILISATIONS
Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).
You may be taking a second look at your favorite candy after hearing this week's news about titanium dioxide. Recently, a lawsuit was filed against Mars, Inc. based on claims that the manufacturer's popular Skittles candy is unfit for human consumption. The class-action lawsuit, filed in U.S. District Court for the Northern District of California in mid-July, alleged that the candy contained heightened levels of a known toxin called titanium dioxide — a food additive that the company previously pledged to phase out from their products in 2016, according to the Center for Food Safety.
We even use titanium dioxide when brushing our teeth as it’s found in many toothpastes.
Titanium dioxide safety is evaluated by regulatory agencies all over the world based on scientific studies.
Titanium dioxide is used a food colour (E171) and, as with all food colours, its technological function is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is also present in cosmetics, paints, and medicines.

It is suitable as an alternative to titanium dioxide when higher acid resistance is required, such as in adhesive joints and sealants.
