Abstract

A method of treating the hair including providing a concentrated hair care composition in a mechanical foam dispenser. The concentrated hair care composition includes one or more silicones, from about 1% to about 5% perfume, and is substantially free of high melting point fatty compounds. The method also includes dispensing the concentrated hair care composition from the mechanical foam dispenser as a dosage of foam; applying the foam to the hair; and rinsing the foam from the hair. The foam has a density of from about 0.025 g/cm³ to about 0.3 g/cm³ when dispensed from the mechanical foam dispenser.

Claims

1. A method of treating the hair, the method comprising:

a. providing a concentrated hair conditioner composition in a mechanical foam dispenser, wherein the concentrated hair conditioner composition comprises;

i. from about 10% to about 14% of an aminopropylaminoethylpolysiloxane, by weight of the concentrated hair conditioner composition, wherein the aminopropylaminoethylpolysiloxane is in the form of a nanoemulsion;

ii. from about 1% to about 5% perfume, by weight of the concentrated hair conditioner composition;

iv. from about 60% to about 90% water, by weight of the concentrated hair conditioner composition;

v. optionally, from about 1% to about 3% cetyltrimethylammonium chloride, by weight of the concentrated hair conditioner composition;

wherein the concentrated hair conditioner composition is free of one or more high melting point fatty compounds;

b. dispensing the concentrated hair conditioner composition from the mechanical foam dispenser as a dosage of foam;

c. applying the foam to the hair; and

d. rinsing the foam from the hair;

wherein the foam has a density of from about 0.025 g/cm³ to about 0.3 g/cm³ when dispensed from the mechanical foam dispenser.

2. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 65% to about 87.5% water, by weight of the concentrated hair conditioner composition.

3. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 12% aminopropylaminoethylpolysiloxane by weight of the concentrated hair conditioner composition.

4. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 3% to about 20% of the nonionic emulsifier, by weight of the concentrated hair conditioner composition.

5. The method of claim 4 wherein the emulsifier is a condensation product of an aliphatic alcohol having from about 8 to about 18 carbons, in either straight chain or branched chain configuration, with from about 2 to about 35 moles of ethylene oxide.

6. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 1.5% to about 4.5% perfume, by weight of the concentrated hair conditioner composition.

7. The method of claim 1, wherein the foam has a dosage weight of from about 1 g to about 5 g to when dispensed from the mechanical foam dispenser.

8. The method of claim 1, wherein the density of the foam is from about 0.075 g/cm³ to about 0.175 g/cm³.

9. A method of treating the hair, the method comprising:

a. providing a concentrated hair conditioner composition in a mechanical foam dispenser, wherein the concentrated hair conditioner composition comprises;

i. about 12% of an aminopropylaminoethylpolysiloxane, by weight of the concentrated hair conditioner composition, wherein the aminopropylaminoethylpolysiloxane is in the form of a nanoemulsion;

ii. from about 1.5% to about 4.5% perfume, by weight of the concentrated hair conditioner composition;

iv. from about 60% to about 90% water, by weight of the concentrated hair conditioner composition;

v. optionally, from about 1% to about 3% cetyltrimethylammonium chloride, by weight of the concentrated hair conditioner composition;

wherein the concentrated hair conditioner composition is free of one or more fatty compounds;

b. dispensing the concentrated hair conditioner composition from the mechanical foam dispenser as a dosage of foam;

c. applying the foam to the hair; and

d. rinsing the foam from the hair;

wherein the foam has a density of from about 0.025 g/cm³ to about 0.3 g/cm³ when dispensed from the mechanical foam dispenser.
