Viscous composition
A viscous composition of the present invention comprises specific cellulose fibers (A), (A′) and (A″) which are selected according to uses of a cosmetic composition, a gel-like composition and a spray composition. By using the composition of the present invention, a cosmetic composition which is excellent in shape retention ability and dispersion stability and excellent in water tolerance to satisfy the properties and the performance which is necessary for cosmetics; a gel-like composition wherein gel-state can be kept without separation or water release; and a spray composition wherein various functional additives which is necessary for the use is mixed without any problem can be obtained.
1. A cosmetic composition containing components (A)-(C):
(A) cellulose fibers having a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 100 nm, wherein the cellulose has a cellulose I-type crystal structure; the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule is selectively oxidized and modified into an aldehyde group and a carboxyl group; and
the amount of the carboxyl group is from 0.6 to 2.2 mmol/g,
(B) water, and
(C) oily materials.
2. The cosmetic composition according to claim 1 , wherein the cellulose fibers of component (A) are oxidized with a co-oxidizing agent in the presence of an N-oxyl compound.
