SHELLAC ALEURITIC POWDER

ORIGIN

"SSGJ 707" SHELLAC ALEURITIC POWDER is isolated by saponification from the Natural and Eco Friendly Resin Lac (Shellac) and is used very widely in the Perfume Industry.

PRODUCT PROFILE

Out of the thirty component acids present in lac molecule, one of the measure component acid popularly known as "aleuritic acid" (9,10,16 - trithydroxy palmitic acid) is believed to be present to the tune of 35-40% (quantitative estimated value) in lac resin but is not commercially recovered to the desired extent by conventional method of alkaline hydrolysis. This happens probably due to the complexity of lac molecule. On the other hand, there is a growing demand of aleuritic acids in the fields of perfumery and pharmaceuticals by virtue of being an excellent starting raw material for the synthesis of : Civetone, Exaltone, Ambrettolide, Isoambrettolide etc. having musk like odour for the perfume industry.

CIVETONE

"CIVETONE" obtained from Shellac Aleuritic Powder is the actual product used by the Perfume Manufacturers. This was originally obtained from the gland of the "Civet Cat" which was from Southern India and Ethopia. Now this animal is becoming extinct but the demand of "CIVETONE" is very much there with the growing of the Perfume Industry. The availability of the Natural Musk from other sources e.g. the MUSK DEER is also finishing as such the demand of Synthetic Musk "CIVETONE" is fast growing and is very much in demand with perfume manufacturing companies in Countries such as France, Italy, Germany, U.S.A etc.
