Chemical property
Shellac red is a mixture of 5 components, from purple red to bright red powder. Soluble in lye, slightly soluble in water, ethanol and propylene glycol, and the higher the purity, the smaller the solubility in water. The solubility at 20ºC is 0.0335%(water), 0.916%(95% ethanol). Under acidic conditions, it is stable to light and heat, but the color of the Chemicalbook changes with the difference of pH value. When the pH value is less than 4.5, it is orange yellow, when the pH value is 4.5 ~ 5.5, it is purple red when the pH value is greater than 5.5, and it is faded when the pH value is greater than 12. Metal ions such as copper and iron will precipitate. Maximum absorption wavelength 488nm. Rat transoral LD501.8g/kg.

Chemical property
Purple brown acicular crystal, melting point 147ºC, rotation αD20=+135°(benzene). Soluble in pheneether, acetone, chloroform, methanol, ethanol, glycerin, animal and vegetable oil and alkaline aqueous solution, insoluble in water. Color Chemicalbook varies with Ph, Ph 4 to 6 is red, Ph 8 is purple, and Ph 10 to 12 is blue. Light resistance, heat resistance, oxidation resistance is good, the reduction dose is unstable, in case of iron ions is deep purple. It has certain antibacterial effect.

  Lac red pigment is one of the most widely used natural pigments, it is an extract from animals. The use of lac red pigment is earlier than the use of lac resin, lac red pigment is traditionally used in food, medicine, cosmetics, printing and dyeing and textile industries, its color itself is red or peach, but other shades can be obtained through mordant preparation.
