It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
INCI names often differ greatly from systematic chemical nomenclature or from more common trivial names and is a mixture of conventional scientific names, Latin and English words. INCI nomenclature conventions "are continually reviewed and modified when necessary to reflect changes in the industry, technology, and new ingredient developments". [2]
Stains-all is metachromatic and changes its color dependent on its contact to other molecules. [3] The detection limit for phosphoproteins is below 1 ng after one hour of staining, [4] for anionic polysaccharides between 10 and 500 ng. [5] [6] Highly anionic proteins are stained blue, proteoglycans purple and anionic proteins pink. [7]
Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.
Sodium cocoate is a mixture of fatty acid salts of coconut oil that is used in some soaps. [1] Sodium cocoate is produced by hydrolysis of the ester linkages in coconut oil with sodium hydroxide, a strong base. The CAS number for sodium cocoate is 61789-31-9.

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Bismarck brown Y also called C.I. 21000 [1] and C.I. Basic Brown 1, [1] is a diazo dye with the idealized formula [(H 2 N) 2 C 6 H 3 N 2] 2 C 6 H 4. The dye is a mixture of closely related compounds. It was one of the earliest azo dyes, being described in 1863 by German chemist Carl Alexander von Martius. It is used in histology for staining ...
