Sodium saccharin or saccharin as an artificial sweetener is usually in the form of salts in the form of calcium, potassium, and sodium saccharin with the chemical formula (C14H8CaN2O6S2.3H2O), (C7H4KNO3S.2H2O), and (C7H4NaNO3S.2H2O). In general, saccharin salts are white crystals, odorless or have a weak aromatic odor, and dissolve easily in water, and taste sweet. Saccharin has a relative sweetness of 200 times the sweetness of sucrose with no caloric value. The combination of its use with other low-calorie artificial sweeteners is synergistic.

Brass salt is used in the electroplating industry to produce golden yellow deposits. Can be used either warm or cold, it is recommended to operate in warm conditions as it can produce brass better than cold. The deposits obtained are usually golden yellow in color but any color from pale yellow to reddish gold may be obtained from the same dyeing process by varying the temperature and current density.

Copper cyanide or Copper (I) cyanide is an inorganic compound with the formula CuCN. This white solid occurs in two polymorphs. Impure samples may turn green due to the presence of Cu (II) impurities. This compound is useful as a catalyst, in copper electroplating, and as a reagent in the preparation of nitriles.

Silvery cyanide is commercially available and supplied as a low temperature polymorph. It can be prepared by reducing copper (II) sulfate with sodium bisulfite at 60 ° C, followed by addition of sodium cyanide to precipitate pure LT-CuCN as a pale yellow powder.

PT Merck Tbk is a multinational company engaged in the pharmaceutical and chemical sector in Indonesia. In the pharmaceutical sector, they manufacture and sell well-known pharmaceutical brands such as Neurobion®, Sangobion® and Glucophage® with cGMP certified facilities. In the chemical sector, Merck markets a wide variety of chemicals, dyes and a wide range of other chemical specialties.

Boric acid (boric acid) is a chemical compound that dissolves easily in water. Boric acid has been used since the 1600s, when chemists produced this compound by reacting boric with sulfuric acid.

Various industries use Boric acid which is considered to have relatively low toxicity. Various products containing Boric Acid can also be found on the market, ranging from insecticides to cosmetics.

Boric acid can be used for various industrial processes such as processing wood, making various refractory materials, making cement, and creating controlled reactions in nuclear power plants. Boric Acid is also a good preservative and dryer (moisture absorber).

Boric acid has a number of medicinal benefits as well. This compound works as a mild antiseptic and is effective in treating several skin conditions such as acne and minor rashes. Boric acid is commonly used to treat fungal infections and in diluted form it is used as an eye wash.

Paraformaldehyde is the smallest polyoxymethylene, formalin polymerization product with a typical polymerization rate of 8-100 units. Paraformaldehyde generally has a slight formaldehyde odor due to decomposition.

Thiourea is an organic compound similar to urea, except that 1 oxygen atom is replaced with a sulfur atom. There are 2 types of thiourea, namely thiourea oxide and thiourea sulfide. The type of thiourea that functions to dissolve gold is thiourea sulfide, or often referred to as thiocarbamide.

Thiourea is a gold solvent solution to replace cyanide, because of the non-toxic nature of this chemical compound. In several countries that have banned the use of cyanide, the use of thiourea has begun to be massive. Gold with thiourea forms complex solutions, where gold thiourea is a complex cation, but is different from other gold complex compounds (cyanide gold, thiosulfate gold, and tertachloroaurate which form anions).

Salicylic acid is a chemical made from complex carbohydrates in the willow tree. The origin of the name of this substance itself is taken from the Latin name of the willow tree, namely Salix. Usually, this substance is often found in aspirin as a pain reliever. However, this content is also often used in facial soaps for acne prone skin because it can help improve cell regeneration in the skin.
