The present invention relates to a composition for treating keratin fibers, preferably hair, comprising: (a) at least one silicone oil in an amount of 20% by weight or more relative to the total weight of the composition; (b) water; and (c) at least one polyol in an amount of 10% by weight or more relative to the total weight of the composition, wherein the ratio of the amount of the (b) water/the amount of the (c) polyol is 3 or less. The composition according to the present invention can also provide keratin fibers such as hair with improved cosmetic effects such as smoothness (e.g., smooth combing even if the keratin fibers are wet, and smooth feeling to touch when the keratin fibers are dry), ease of running fingers through the keratin fibers even if the keratin fibers are wet, moist feeling even if the keratin fibers are dry, less stickiness (or less greasy) on hair when the keratin fibers are dry, and volume down control (therefore, it can be easy to style the shape of keratin fibers, due to anti-fizz properties of the composition according to the present invention).

The present invention relates to a composition, preferably cosmetic, comprising: at least one rosewood extract comprising polyphenols, and at least one solvent selected from:
polyols comprising at least three hydroxy functions,
mixtures of at least one polyol comprising at least three hydroxy functions and water, and
mixtures of at least one polyol comprising at least three hydroxy functions and at least one diol
comprising from 2 to 4 carbon atoms,
the weight ratio of rosewood extract to solvent being strictly less than 7:13.

A microemulsion composition containing: (A) a polyether-modified organopolysiloxane shown in the following general formula (1) having an HLB of 8.0 or more calculated by Griffin's method; (B) a polyether-modified organopolysiloxane shown in the following general formula (7) having an HLB of 5.0 or less calculated by Griffin's method; (C) a glycerol derivative shown in the following general formula (8); (D) a polyhydric alcohol other than the (C); (E) a silicone oil having a kinematic viscosity of 20 mm.sup.2/s or less at 25° C.; and (F) water, where a ratio (A)/(B) of a mass of the (A) to a mass of the (B) satisfies 1.0 to 15.0 and the microemulsion composition has a transparent to translucent appearance at 25° C. This provides a microemulsion composition having a transparent to translucent appearance.
