Description
Canthaxanthin, also known as red diketocarotenoid or 4,4'-diketo-β-carotene, is a common xanthophyll found naturally in microorganisms, marine organisms, and certain animals. It acts as an antioxidant in living organisms, with its potential antioxidant activity attributed to the presence of conjugated double bonds in its structure. Canthaxanthin is a synthetic red colorant with the most intense red color, available in oil-soluble, oil-dispersible, and water-dispersible forms. It has fair pH, heat, light, and chemical stability with a low tinctorial strength and does not possess vitamin A activity.
Uses
Used in Food Industry:
Canthaxanthin is used as a coloring agent for various food products, such as carbonated soft drinks, salad dressing, and spaghetti sauce, due to its intense red color and stability.
Used in Pharmaceutical Industry:
Canthaxanthin is used as an oral suntanning agent to provide a healthy skin tone without exposure to sunlight.
Used in Cosmetics Industry:
Canthaxanthin is used as an antioxidant to promote skin health and protect against environmental damage.
Used in Animal Feed Industry:
Canthaxanthin is used as a color additive in the feed of salmon and poultry to enhance the natural color of their flesh, making it more appealing to consumers.
Used in Medicine:
Canthaxanthin is used in the medical field for its antioxidant properties, which can help protect cells from damage and support overall health.
Brand Names:
Apotrin and Phenoro are some of the brand names associated with Canthaxanthin.
World Health Organization (WHO)
Canthaxanthin, a naturally-occurring carotenoid with a deep redorange
colour, is widely used as a food colouring agent. Since the mid-1970s it has
been included in oral 'artificial suntan' preparations. It is also available in
preparations used in the treatment of certain photodermatoses. By the mid-1980s
its use in such preparations had been associated with the accumulation of
crystalline deposits in the retina. Reported functional changes relating to dark
adaptation have been of marginal clinical significance and largely reversible.
Nevertheless, this has led to the withdrawal of artificial suntan preparations
containing canthaxanthin by several regulatory authorities. Preparations for
treatment of photodermatoses remain available in some but not all of these
countries.
Hazard
Oral intake may cause loss of night vision.
Safety Profile
When heated to
decomposition it emits acrid smoke and
irritating fumes.
Purification Methods
Purify canthaxanthin by chromatography on a column of deactivated alumina or magnesium oxide, or on a thin layer plate of silica gel G (M
Check Digit Verification of cas no
The CAS Registry Mumber 514-78-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 514-78:
(5*5)+(4*1)+(3*4)+(2*7)+(1*8)=63
63 % 10 = 3
So 514-78-3 is a valid CAS Registry Number.

Paragraph 0043-0057; 0062-0063, (2021/03/30)
The invention belongs to the field of compound synthesis, and relates to a cantharidin preparation method, which comprises: carrying out an oxidation reaction on beta carotene in a solvent in the presence of an oxidizing agent, a catalyst and a strong acid salt of divalent manganese ions, performing standing for layering after the oxidation reaction is finished, washing and purifying the oil layer, and concentrating to remove the solvent, and then adding an isomerization solvent to carry out isomerization reaction, and filtering and drying after the isomerization reaction is finished to obtainthe all-trans cantharidin. The cantharidin prepared by adopting the method provided by the invention has the advantages of good oxidation effect, lower oxidant dosage and higher cantharidin yield (upto 86% or above), and the obtained cantharidin is a purple red acicular crystal with the content of more than 90%. Then, a water layer is treated by adopting the method provided by the invention andthen is recycled, so that the consumption of an oxidant can be reduced, the cost is reduced, and meanwhile, the discharge of halogen-free acid salt wastewater is realized.
