Abstract

Disclosed herein is a hair care product is provided, which comprises an oil-in-water emulsion A and an oil-in-water emulsion C, wherein emulsion A has a pH-value from greater than 7.0 to 12.0 and contains: a1) at least one cationic surfactant A, and a2) at least one amino-functionalized silicone A; and emulsion C has a pH-value from 2.0 to lower than 7.0, and contains: c1) at least one cationic surfactant C, wherein surfactant A and surfactant C may be identical with or different from each other, and c2) at least one silicone C, wherein silicone C and the amino-functionalized silicone A may be identical with or different from each other, wherein emulsion A and emulsion C are separated from each other before use. Also disclosed herein is a process for hair caring by using the hair care product as contemplated herein.

Claims (40)

1. A hair care product comprising:

an oil-in-water emulsion A, wherein emulsion A has a pH-value from greater than about 7.0 to about 12.0 and comprises:

a1) steartrimonium bromide, and

a2) amodimethicone;

an oil-in-water emulsion I, wherein emulsion I has a pH-value from about 4.0 to about 9.0 and comprises:

i1) at least one surfactant I, and

i2) at least one silicone I, and

an oil-in-water emulsion C, wherein emulsion C has a pH-value from about 2.0 to lower than about 7.0 and comprises:

c1) bentrimonium chloride, wherein the at least one surfactant I may be identical with or different from a1) and c1), and

c2) a mixture of dimethicone and cyclopentasiloxane,

wherein the at least one-silicone I may be identical with or different from a2) and c2),

wherein emulsion A, emulsion I, and emulsion C are non-leave-on emulsions, and

wherein emulsion A, emulsion I, and emulsion C are provided in separate containers.

2. The hair care product according to claim 1 , wherein emulsion A comprises:

about 0.1 to about 10.0 wt._% of a1) steartrimonium bromide, and

about 0.1 to about 20 wt._% of a2) amodimethicone, based on the total amount of 100 wt % emulsion A.

3. The hair care product according to claim 1 , wherein emulsion C comprises:

about 0.1 to about 10 wt._% of c1) bentrimonium chloride, and

about 0.1 to about 25 wt._% of c2) the mixture of dimethicone and cyclopentasiloxane,

based on the total amount of 100 wt_% emulsion C.

4. The hair care product according to claim 1 , wherein emulsion A, emulsion C, or both emulsion A or emulsion C, further comprise pentaerythrityl tetraethylhexanoate and optionally cetearyl alcohol or.

5. The hair care product according to claim 1 , wherein:

emulsion A comprises:

about 0.1 to about 10.0 wt._% of a1) steartrimonium bromide, and

about 0.1 to about 20 wt._% of a2) amodimethicone, based on the total amount of 100 wt._% emulsion A; and

emulsion C comprises:

about 0.1 to about 10 wt._% of c1) bentrimonium chloride, and

about 0.1 to about 25 wt._% of c2) a mixture of dimethicone and cyclopentasiloxane,

based on the total amount of 100 wt % emulsion C.

6. A process for hair caring comprising the following steps in sequence:

step a) applying an oil-in-water emulsion A to hair, where emulsion A has a pH value from greater than about 7.0 to about 12.0 and comprises:

a1) steartrimonium bromide, and

a2) amodimethicone;

step i) applying an oil-in-water emulsion I to the hair, where emulsion I has a pH-value from greater than about 4.0 to about 9.0 and comprises:

i1) at least one surfactant I, and

i2) at least one silicone I;

step b) washing the hair;

step c) applying an oil-in-water emulsion C to the hair, wherein emulsion C has a pH value from about 2.0 to lower than about 7.0 and comprises:

c1) behentrimonium chloride, and
