Patent Application
20080038206
In the following examples, the individual active ingredient compositions were filled, along with the individually indicated propellants, into a pressure-resistant aerosol can and equipped with a capillary spray system, as can be obtained, for example, under the trade name TRUSPRAY® from Boehringer Ingelheim microParts GmbH. Valve diameters and valve balls of different sizes can be used; however, the following sizes are preferred:
Active ingredient composition:
optional addition:
Viscosity: 1,000- 1,200 mPas (25° C.))
pH value: 8.6
Fill ratios in wt %:
The time-consuming application with the brush is no longer necessary. The product can also be of particular good use as a hair root cream for targeted shaping of the hair roots. The product is also particularly well suited for use in conjunction with an aqueous, non-viscous permanent wave lotion for optimum targeting of the structural differences between the hair roots and the hair tips during the permanent wave procedure.
Active ingredient composition:
Viscosity: 400- 1,000 mPas (shear speed 12.9 s-l, 25° C.)
pH value: 2.2- 2.8
Active ingredient composition:
Viscosity: 2,000- 3,000 mPas (25° C.)
pH value: 9.0
Fill ratios in wt %:
Active ingredient composition:
Viscosity: 4,000-6,000 mPas (shear speed 12.9 sol, 25° C.)
pH value:2.0- 2.6
Fill ratios in wt %:
The creamy composition of Examples 1 through 4 mean that they are very user-friendly in their application, i.e., they can be sprayed directly and precisely on the parts of the hair to be treated or on the hair roots without requiring any awkward use of the brush.
Active ingredient composition:
pH 8.6; viscosity: 2,700 mPas)(Haake visc. VT 550, SV DIN, shear speed 12.9 s−1, 25° C.)
Aerosol fill:
The active ingredient composition is filled with dimethylether in a weight ratio of active ingredient: propellant=50:50 and 60:40.
Treatment of the hair for a root perm touch up:
Spraying gel onto the rolled-up root hair using the product release system, rinsing after an action period (8-15 min), then fixing. Only the root perm is touched up.
Results: New wave and movement in the hair root area; gentle treatment of the middle hair sections and tips, because they are not re-permed. This results in the following: excellent hold and very good combing properties in the hair, convenience and safety for the user due to the drop stability of the wave agent gel, user-friendly application of the thickened permanent wave agent, and the labor-intensive application with the brush no longer needed.
Active ingredient composition phase 1:
pH 8.2
Active ingredient composition phase 2:
pH 8.6; viscosity: 2,700 mPas (Haake viscometer VT 550, SV DIN, shear speed 12.9s−1, 25° C.) Phase 1 is used as a low-viscosity lotion; phase 2 is filled together with propellant to be used in a product release system according to the invention.
Aerosol filling of phase 2:
The common propellants can be used; dimethylether is preferably used. The active ingredient composition is filled in a weight ratio of active ingredient: propellant=50:50 and 60:40.
The 2-phase use enables evening out of large structural differences in the hair from the hair roots up to the hair tips.
Hair treatment: Application of liquid phase 1 of the wave agent to the rolled-up hair, then spraying thickened phase 2 of the gel to the rolled-up hair roots using the product release system according to the invention, rinsing after an action period (6-15 min), then fixing.
Results: Even wave from the hair roots to the tips, gentle treatment of the hair tips, excellent hold and very good combing properties for the hair; user-friendly application of the thickened permanent wave, agent of phase 2, omission of the otherwise customary and labor-intensive application with the brush.
Active ingredient composition:
pH 3.5; viscosity: 750 mPa s (Haake viscometer VT 550, SV DIN, 25° C.)
Aerosol fill:
The common propellants can be used; dimethylether is preferably used. The active ingredient composition is filled in a weight ratio of active ingredient: propellant=50:50, 60:40, and 70: 30.
Hair treatment:
Spraying the fixing gel on the rolled-up hair roots with the product release system according to the invention after rinsing out the wave agent, rinsing out after an action period (5-12 min), reapplying the fixing agent to the hair (post-fixing) after unrolling, rinsing out after another action period of 2-5 min.
Advantages: User-friendly application of the thickened fixing agent. The labor-intensive application of the agent with the mixing bowl and brush is no longer necessary.
Active ingredient composition:
pH 9.0; viscosity: 5,100 mPas (Haake visc. VT 550, SV DIN, shear speed 12.9 s−1, 25° C.)
Aerosol fill:
The common propellants can be used; dimethylether is preferably used. The active ingredient composition is filled in a weight ratio of active ingredient: propellant=50:50 and 60 40.
Hair treatment:
Spraying the gel on dry hair with the product release system according to the invention and smoothing the hair with a comb (the comb can also be a part of the applicator), rinsing out after an action period (10 to 30 min), then fixing (action period of the fixing agent is 5 to 12 min); then, if necessary, use of a hot smoothing iron.
Results: Smooth hair with excellent hold and very good combing properties; the product release system according to the invention enables the application of very viscous gel that does not drip off or run onto the scalp; the convenience and safety for the user is therefore significantly improved; user-friendly application of the thickened permanent wave agent; time-consuming application with the brush no longer necessary.
Active ingredient composition:
pH 3.5; viscosity: 3,550 mPas (Haake viscometer VT 550, SV DIN, shear speed 12.9 s−1, 25° C.)
Aerosol fill:
The common propellants can be used; dimethylether is preferably used. The active ingredient composition is filled in a weight ratio of active ingredient: propellant=50:50, 60:40,and70 :30.
Hair treatment:
Spraying the fixing gel on the smoothed hair with the assistance of the product release system according to the invention after the reduction-agent-containing smoothing agent is rinsed out, rinsing out the fixing gel after an action period (5-12 min), and subsequently, if necessary, use of a hot smoothing iron.
Advantages: The product release system according to the invention enables the application of very viscous oxidizing-agent-containing gel that does not drip off or run off onto the scalp. The convenience and safety for the user is therefore significantly improved. An additional advantage is the user-friendly use of the thickened fixing agent. The time-consuming application with the brush is no longer necessary.
