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 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. ^ 24 cl, 2 tbl, 809 ex |
