Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of the skin. While this categorization is easy and logical it turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum).

2: Clarification mechanism of coagulant
Chemical coagulation is a process in which chemical agents (coagulants) are added to water treatment to make colloidal dispersion system destabilize and agglomerate. In the coagulation process, small suspended particles and colloidal impurities are aggregated into larger solid particles to separate particulate impurities from water, which is called coagulation clarification.
After adding coagulant into water, colloidal particles and other small particles can be polymerized into larger flocs through the comprehensive action of mixing, coagulation and flocculation. The whole process of coagulation and flocculation is called coagulation.
(1) Destabilization and condensation of colloids
Adding electrolyte to water can compress the electric double layer and destabilize the colloid. The main mechanism is that the electric double layer of colloidal particles in water is compressed or neutralized by adding aluminum salt or iron salt coagulant. The coagulant and raw water are mixed rapidly and evenly, and a series of chemical reactions are produced to destabilize. This process takes a short time, generally about 1 min. Some cationic polymers can also play a role in the destabilization and condensation of colloids in water. These polymers have a long chain structure and positive charge in water. Their destabilization and condensation of colloids in water is due to the interaction of van der Waals force adsorption and electrostatic attraction.
(2) Flocculation and formation of floc (alum)
The particle size of the initial flocculate formed by colloid destabilization and coagulation in water is generally more than 1 m. at this time, Brownian motion can no longer push them to collide and form larger particles. In order to make the initial flocs collide with each other to form large flocs, it is necessary to input additional energy into the water to produce a velocity gradient. Sometimes it is necessary to add organic polymer flocculant into water, and the adsorption bridging effect of long chain molecules of flocculant is used to improve the probability of collision and adhesion. Flocculation efficiency usually increases with the increase of flocculate concentration and flocculation time.
Compared with polyaluminum chloride, polyaluminum chloride has the advantages of high density, fast settling speed and wide pH adaptability; the coagulation effect is less affected by temperature than that of polyaluminum sulfate; however, when adding ferric salt, it should be noted that when the equipment is not in normal operation, the iron ions will make the effluent color, and may pollute the subsequent desalination equipment. - In addition to these benefits, titanium dioxide also enhances the paint's scrub resistance, stain resistance, and washability. These attributes are particularly important in high-traffic areas or environments prone to dirt and moisture, ensuring that walls retain their original appearance for longer periods.

Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), zinc sulfide, and white lead.[1]

When we purchase lithopone, we must pay attention to its ratio. This can be seen to some extent from the appearance. Basically, we can see that good products are very delicate. , and the color is also very uniform, a kind of shiny white, while inferior lithopone has uneven particles and wrong luster.
- A paint pigment factory is a bustling hub of precision and innovation, where the journey from mineral or chemical compound to finished product is a testament to human ingenuity. The primary function of these factories is to extract, refine, and blend pigments, which are the substances responsible for giving paint its color. These pigments can be natural, derived from sources like clay, earth, or plants, or synthetic, created through chemical processes.

1. Purity The purity of barium sulphate is essential, especially in applications such as pharmaceuticals. Suppliers should provide certifications stating the purity levels and any presence of impurities or contaminants.
When choosing lithopone, you must choose a good brand and pay attention to its production date. Some people just don’t pay attention to this aspect and often pursue cheap prices. As a result, they buy products that are close to their expiration date and have not been stored for long. It is no longer usable. This is very important.

titanium oxide tio2 manufacturers. It is essential to choose a manufacturer that has the ability to produce the required amount of titanium oxide within a specified timeframe. This ensures that there are no delays in the production process and that the product is readily available when needed.
After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body, Maged Younes, chair of the European Food Safety Authority's expert Panel on Food Additives and Flavourings, said in a May 2021 statement.


Lithopone is rather nontoxic, due to the insolubility of its components. It has been used in medicine as a radiocontrast agent. Lithopone is allowed to be in contact with foodstuffs in the US and Europe.
What Is Titanium Dioxide?

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.
