Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
93 words
A deodorant distillate produced by a process which comprises dry-distillation of the leaves of Thea sinensis, said distillate having a boiling point of 180°-200° C. (at 20 mm/Hg) and exhibiting the following properties in a 20 w/w% propylene glycol solution: ______________________________________
Refractive index
n.sub.D.sup.20 = 1.418 ± 0.02
Angle of optical rotation
α.sub.D.sup.20 = 0.007° ± 0.002°
Specific gravity
d.sub.20.sup.20 = 1.025 ± 0.02
Ultraviolet absorption
276 ± 2 mμ (20 w/w % propylene
maximum peak glycol solution diluted
by water in the amount of
1.000 times the weight of
said solution).
