Abstract

The present invention relates to hair grooming device comprising a head, a nebuliser, a power supply therefore and a reservoir containing a composition to be applied to the hair during use by the nebuliser, the composition comprising a solution comprising hydrocarbon having an average carbon chain length of 13 or less and a benefit agent, and wherein the composition has a viscosity of 4.5 cSt or less 25 DEG C.

Description

The device and the preparation that are used for hair

Technical field

The preparation that the present invention relates to a kind of Hair setting device (hair grooming device) and use with this device.

Summary of the invention

The present invention relates to by Hair setting device deposition benefit materials (benefit agent) (particularly polysiloxanes) problem.

Therefore, the invention provides a kind of Hair setting device, comprise head, nebulizer (nebuliser), its power supply and comprise in use the bank (reservoir) of the compositions of using to hair by nebulizer, said composition comprise comprise have 13 or the solution of the hydrocarbon of shorter average carbon chain length degree and benefit materials and wherein said composition under 25 ℃, have 5cSt or lower viscosity.

Preferably, head is to be with bristle (bristle) or tooth, and more preferably this device is comb or brush.Most preferably it is a brush.

Nebulizer is selected from nebulizer known in the art.Preferably, nebulizer comprises the silk screen that limited by stiffening ring, comprises the bank of compositions to be atomized and is connected to the circuit of power supply.This nebulizer can be from Aerogen

Be purchased.

Preferably, silk screen protrudes with respect to bank.This helps, and atomizing fluids moves on hair in the use.

Preferably, nebulizer is arranged in head, and head also comprises the hole that in use discharges atomizing fluids on hair.Preferably, this hole is hole or the groove in the head.In preferred embodiment, there are a plurality of holes.

If this device is a brush, then preferred hole is positioned at the center on brush.More preferably, hole is centered on by bristle.In the situation that has an above hole, preferred hole is arranged on the brush symmetrically, so that the even release of atomizing fluids to be provided.

If this device is a comb, the then preferred a plurality of holes that are positioned evenly on combing one's hair that exist.

Preferably, nebulizer is arranged in the chamber of device, and this chamber is by passage and external communications.

Preferably, this device comprises the shank that holds power supply.Perhaps, power supply can be independently, and this device can pass through network supply.

The compositions that is comprised in the bank comprises and has 13 or the hydrocarbon of shorter average carbon chain length degree.

Benefit materials can be selected from wetting agent (moisturiser), anti-wrinkle agent, hair nutrition thing etc., spice, silicone oil, wax, higher fatty acids, quintessence oil, lipid, skin freshener (skin coolant), vitamin, opacifier, glycerol, hair fixing copolymer, coloring agent, hair conditioner, hair growth promoting agent, vitamin, the hair straightening agent, hair growth promoter, the alopecia inhibitor, antimicrobial compound, antifungal compound, anti-inflammatory compound, pruritus, sebum inhibitor, sunscreen and composition thereof.

Benefit materials is polysiloxanes preferably.

Suitable polysiloxanes comprises polydiorganosiloxanepolyurea (polydiorganosiloxane), and particularly the CTFA name is called the polydimethylsiloxane of dimethicone (dimethicone).

Preferably polysiloxanes has the viscosity that is lower than 1000cSt in the time of 25 ℃, more preferably less than the viscosity of 700cSt, more preferably less than the viscosity of 500cSt.Have 350 or the polysiloxanes of following viscosity be particularly preferred.

Suitable polysiloxanes with required viscosity can obtain from Dow Corning, Wacker, GE and Clearco.The example of these polysiloxanes be from Dow DC200, Wacker AK 350 and from the pure Silicone Fluid 350cSt (food stage) of Clearco.

Preferably, the total content of the polysiloxanes in the compositions is lower than 2 weight %, more preferably 1 weight % or following.

Be used for hydrocarbon of the present invention and have 13 or shorter average hydrocarbon chain length, preferred hydrocarbon chain has the average chain length degree greater than 6, and more preferably hydrocarbon has 8 to 12 average chain length degree.Suitable primary solvent comprises Fancol ID and isoparaffin (isoparrafin) H (C9-12) (Isopar H).

Of the present invention aspect some in, solvent system can comprise at least two kinds of compositions.The suitable secondary solvent that is used for this solvent mixture comprises ring penta siloxanes, isopropyl palmitate and isopropyl myristate.The content of secondary solvent should not surpass 20 weight % of solvent mixture, and the content of preferred secondary solvent should not surpass 10 weight %.

The hydrocarbon that exists in this compositions is preferably so that wherein they can dissolve useful amount of substance and exist.The content of preferred hydrocarbons is the 80 weight % that are higher than total composition, when more preferably being higher than 90 weight %, most preferably is higher than 95 weight %.

The viscosity of final composition is 4.5cSt or lower down at 25 ℃, more preferably is 4cSt or lower down at 25 ℃.Preferred viscosities 25 ℃ down for 1.5cSt or more than, more preferably be higher than 2cSt.

Preferably, use the compositions of this system applies staying on the hair after the application, rather than wash (in 10 minutes of using) at once off.This series products is called as leave (leave in) compositions.

Brief Description Of Drawings

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

Fig. 1 is that 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
