Brief Description Of Drawings

With reference to following nonrestrictive accompanying drawing the present invention is described, wherein:

Fig. 1 is the schematic cross-sectional of brush of the present invention, and Fig. 2 a, b and c are the plane graphs of brush of the present invention.

The specific embodiment

Fig. 1 has shown the brush 1 that is connected with the shank 2 that holds power supply 3 in detail.Brush 1 holds nebulizer 10, and described nebulizer 10 is made up of support 5 that is used for silk screen 7 and the bank 6 that comprises hair care composition.Brush 1 also has the hole 9 of the hair care composition that is used to discharge atomizing the bristle 8 that hangs down from brush and the brush 1.

Fig. 2 shows 3 kinds of embodiments of hole of the present invention.Fig. 2 a shows to have the hole 9 that extends and centered on by bristle 8 in all sides under the brush mediad.In Fig. 2 b, there are 3 evenly at interval and perpendicular to the hole of vertical main shaft (general longitudinal axis) (not shown) of brush.In Fig. 2 c, there are 6 holes, it is arranged in two row, three rhombohedral holes of every row.

Below be unrestriced embodiment of the present invention.

Each water-based emulsion of about 1 gram is sprayed in the sealed container of known weight.Water evaporates from container, and the amount of the polysiloxanes of atomizing is measured by the container of weighing again.

Calculate the standard error of this experiment, it is equivalent to the error of deposition value 0.0014 gram.

This result of experiment shows at last, the loss of using emulsion of the present invention not have polysiloxanes to carry.

Use nebulizer to use DC5-7051 (in water, 2wt%) and the DC200 350cSt in the Fancol ID to exsiccant hair (the TA tufts of setting level (switch) of 2.5 grams).Gather the x-ray fluorescence sample from the center of tuft, and measure the content of polysiloxanes.

Material	DC5-7051?2％	DC200?350cSt?0.5％
			(ppm) of expection	700	1500
(ppm) that produces	752±272	550±156
			Account for the percentage ratio of expection	107％±36	37％±28

Above-mentioned data show that the solution of DC200 in Fancol ID that the DC5-7051 emulsion demonstrated at 2% o'clock than 0.5% better deposits (with respect to desired value).
