MIXTURE OF ISOALKANES, PREPARATION OF SAID MIXTURE AND USE Russian patent published in 2011 - IPC C07C9/16 C07C9/22 C07C5/03 A61K8/31 A61Q5/00 A61Q17/04 A61K47/06 A61Q19/10 A61Q15/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a mixture of isoalkanes as oil bodies for cosmetic or pharmaceutical agencies, whose ¹H-NMR-spectrum in the region of a chemical shift δ of from 0.6 to 1.0 ppm relative tetramethylsilane, has a surface integral of from 25 to 70% of the total integral surface. The mixture, which has density from 0.7 to 0.82 g/cm³, contains not less than 70 wt % alkanes with 8-20 carbon atoms, and the fraction of side chains with alkyl groups which have 2 or more carbon atoms is less than 20% of the total number of branching sites and is free from squalane. The invention also relates to a method of preparing said mixture, as well as a cosmetic or pharmaceutical agent based on said mixture and a hair cosmetic agent also based on said mixture.

EFFECT: improved method.
