It can effectively and safely control the signs and symptoms of facial seborrheic dermatitis and can quickly relieve the itching symptoms of patients with dermatitis and eczema as well as reduce the lesion area, clear atopic dermatitis (eczema) sign. Therefore, it is an effective treatment method for the treatment of atopic dermatitis (eczema) for both early remission purpose and long-term control purpose.
Polyacrylamide
Polyacrylamide is called PAM for short. It is usually a high polymer with the head tail bond structure of acrylamide monomer, which is a hard glassy solid at room temperature. Due to different manufacturing methods, the products are white powder, translucent beads and flakes. density 1.302g/cm3 (23 ℃), vitrification temperature 153 ℃, softening temperature 210 ℃. It has good thermal stability. It is clear and transparent when dissolved in water, and its viscosity changes with the increase of polymer molecular weight, and the change of polymer concentration is logarithmic. Except for a few solvents such as acetic acid, acrylic acid, chloroacetic acid, glycol, glycerin and formamide, they are generally insoluble in organic solvents.

Polymyxin B Sulphate
Polymyxin B Sulphate is an antibiotic primarily used for resistant Gram-negative infections. It is derived from the bacterium Bacillus polymyxa. Polymyxin B is composed of a number of related compounds (see "Mixture composition"). It has a bactericidal action against almost all Gram-negative bacilli except the Proteus and Neisseria genera. Polymyxins bind to the cell membrane and alter its structure, making it more permeable. The resulting water uptake leads to cell death. Polymyxins are cationic, basic peptides that act like detergents (surfactants). Side effects include neurotoxicity and acute renal tubular necrosis. Polymyxins are used in the topical first-aid preparation Neosporin.
Polyvinyl Chloride
Poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced polymer, after polyethylene andpolypropylene. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used inconstruction for pipe, and in profile applications such as doors and windows. It can be made softer and more flexible by the addition ofplasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, signage, inflatable products and many applications where it replaces rubber.
Ponatinib
Panatinib is an anticancer drug. In December 2012, it was approved by FDA to be used in the treatment of adult chronic myeloid leukemia (CML) and Philadelphia chromosome positive (Ph + acute lymphoblastic leukemia (all). It is mainly used to treat patients who have no effect on dasatinib or nilotinib treatment, or who cannot tolerate dasatinib or nilotinib, and patients who are not suitable for follow-up treatment of imatinib. It can also be used to treat patients with gene mutation ("T315I mutation"), which makes patients resistant to imatinib, dasatinib or nilotinib. It is also used to treat CML and Ph + all in adults who have not used other TKIs. At present, it is the only available drug for BCR ABL kinase T315I mutation.

Potassium Chromate
Potassium chromate is a kind of inorganic compound, which is yellow orthorhombic or hexagonal crystal at room temperature. Relative density is 2.732, melting point is 968 ℃, toxic. It is easy to dissolve in water. After dissolution, the hydrolysis solution of chromate ion is alkaline and insoluble in alcohol and ether. Add acid to the Yellow potassium chromate solution and the solution turns orange, which is the color of dichromate.
Potassium Ethyl Xanthate
Potassium ethyl xanthate is predominantly used in the mining industry as flotation agent for extraction of the ores of copper, nickel, and silver. The method exploits the affinity of these “soft” metals for the organosulfur ligand. Potassium xanthate is a useful reagent for preparing xanthate esters from alkyl and aryl halides.
Potassium Fluoride
Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry. It is an alkali halide and occurs naturally as the rare mineral carobbiite. Aqueous solutions of KF will etch glass due to the formation of soluble fluorosilicates, although HF is more effective.
Potassium Hydroxide
Potassium hydroxide is an inorganic compound with the formula KOH, commonly called caustic potash. Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base. It has many industrial and niche applications; most applications exploit its reactivity toward acids and its corrosive nature. KOH and NaOH can be used interchangeably for a number of applications, although in industry, NaOH is preferred because of its lower cost.
Potassium Iodide
Colorless or white cubic crystals. Odorless, with a strong bitter and salty taste. Soluble in water, soluble in ethanol, methanol, acetone, glycerol and liquid ammonia, slightly soluble in ether. Its aqueous solution is neutral or slightly alkaline. Potassium iodide is a permitted food iodine fortifier. my country stipulates that it can be used in infant food at a dosage of 0.3-0.6 mg/kg. It can also be used for table salt, and the usage amount is 30-70mL/kg. As a component of thyroxine, iodine participates in the metabolism of all substances in livestock and poultry and maintains heat balance in the body. It is an indispensable hormone for the growth and reproduction of livestock and poultry for lactation. It can improve the growth performance of livestock and poultry and promote the health of the body. If the body of livestock and poultry is deficient in iodine, it will lead to metabolic disorder, body disorder, goiter, affect nerve function, fur color and feed digestion and absorption, and eventually lead to slow growth and development.

Gonadotropins (or glycoprotein hormones) are protein hormones secreted by gonadotrope cells of the anterior pituitary of vertebrates. This is a family of proteins, which include the mammalian hormones follicle-stimulating hormone (FSH), luteinizing hormone (LH), placental chorionic gonadotropins hCG and eCG and chorionic gonadotropin (CG), as well as at least two forms of fish gonadotropins. These hormones are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function.The hormones LH and FSH are secreted by the anterior pituitary gland, while hCG and eCG are secreted by the placenta.
