About appearance and conformation Bosain is a chiral compound with four
different conformations: (β,S conformation, β,R conformation, a,S
conformation, a,R conformation). At present, the commercially available
boswellin is mainly a mixture of β,S and β,R conformations, and the product
has two different appearances: paste-like liquid and powder. The difference
between the two is as follows

Paste liquid bosine: The ratio of S-configuration to R-configuration is between
50% : 50% and 70% : 30%.

Powdered boswellin: the ratio of S to R configuration is 90% : 10%.

According to the research data on L’Oreal’s patent application “New C-
glycoside derivatives and their cosmetic use”, the higher the S-configuration
content, the better the activity and efficacy. We use chiral splitting
technology to obtain boswellin with S: R = 90% : 10% or more, and the product
is a white to off-white powder, which has better activity and efficacy!
