Optical brighteners, also known as fluorescent whitening agents (FWAs) or optical brightening agents (OBAs), are chemical compounds used in various industries, primarily in textiles, paper, and detergents. These substances absorb ultraviolet (UV) light and re-emit it as visible blue light, making colors and whites appear brighter and more vivid. Optical brighteners are often added to laundry detergents to give the illusion of cleaner and whiter clothing by enhancing their visual brightness. They are also used in the paper industry to improve the brightness and whiteness of paper products. Optical brighteners' ability to improve the appearance of materials under certain lighting conditions makes them valuable in enhancing the visual quality of a wide range of consumer and industrial products.
Description: Sodium erythorbate is a white or yellow white crystalline powder or granules, odorless, has little salt, the melting point is over 200, it is rather stable when being dry exposed to the air, but in the water solution, when there is air, metal, heat and light, the oxidation will occur. It easily dissolves in water; 16g/100ml at normal temperature, hardly dissolves in ethanol, the PH value of 2% water solution is 5.5-8.0.
Which complies with the specifications of GB8273-87, FCC for food additives
Net Weight: 25kgs/carton.
Uses: Sodium Erythorbate is mainly used in foodstuff industry, used as antioxidant, preservative and coloring agent, broadly used in meat food, fish food, beer, fruit juice, syrup crystal, fruit and vegetable tin, cake, dairy produce, confiture, sherry, pickles, and grease etc. the dosage to the meat foods is 0.5~1.0g/kg. To the frozen fish, the fish should be infused in the 0.1%-0.8% water solution before freezing. The dosage in the beverage such as syrup is 0.01%~0.03%, apple and bechamel tin: 0.15g/kg (dosage of single or together with the VC), luncheon meat, cooked meat powder, cooked front leg pork, cooked ham, the dosage is 0.5g/kg (dosage of single or together with the VC and other sodium salt, counted the VC ), for the peach, apple jam: 2g/kg,for the fruit tin, it is 0.75-1.5g/l, for the nature syrup, it is 0.08-0.11g/l, for the beer, it is 0.03g/l (FAO/WHO(1977).
Antioxidation property: the antioxidation property of the Sodium Erythorbate is great larger than the one of cenolate (Sodium VC), has no effects to identify the Vitamin C, but it will not persuade the body to absorb and use the Sodium Erythorbate. The body culls the Sodium Erythorbate and changes it into Vitamin C inside the body.
The physiological effects of the Sodium Erythorbate is only the 1/20 of the VC on anti-scurvy, but it is approximately same to the VC on drop blood pressure, diuresis, generating of hepatic glycogen, discharging of pigment, detoxifcation.

The white flake or waxy crystal of Mequinol is mainly used as polymerization inhibitor of vinyl plastic monomer, ultraviolet inhibitor, dye intermediate, and antioxidant BHA for synthesis of edible oil and cosmetics. Its biggest advantage is that the monomer added with MEHQ does not need to be removed when copolymerizing with other monomers. It can be directly copolymerized by ternary, and can also be used as antioxidant, antioxidant, etc.

Introduction
Homosalate CAS 118-56-9 is an organic compound used in some sunscreens. It is made by the Fischer-Speier esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, the latter being a hydrogenated derivative of isophorone. Contained in 45% of U.S. sunscreens, it is used as a chemical UV filter. The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295 nm to 315 nm, protecting the skin from sun damage.
Application
The primary application of Homosalate is in sun care products such as sunscreens, lotions, and moisturizers to provide protection against damaging UV rays.
