Abstract

Described herein is dosage of foam including from about 5 cm³ to about 70 cm³ of the foam. The foam includes from about 0.5 g to about 4 g of a detersive surfactant; from about 0.001 g to about 4 g propellant; a foam density of from about 0.04 g/cm³ to about 0.23 g/cm³; and a bubble size distribution having an R₃₂ of from about 30 μm to about 60 μm.

Claims

1. A dosage of foam shampoo comprising a volume of from about 5 cm³ to about 150 cm³ of the foam, wherein the foam comprises:

a) a detersive surfactant system comprising;

i) from about 15 wt. % to about 30 wt. % anionic surfactant selected from the group consisting of sodium undecyl sulfate, sodium laureth sulfate, sodium lauroyl isethionate, sodium cocoyl isethionate, sodium laurethsulfosuccinate, sodium laurylsulfosuccinate, and mixtures thereof;

ii) from about 2 wt. % to about 12 wt. % zwitterionic surfactant selected from the group consisting of lauramidopropyl betaine, cocoamidopropyl betaine, lauryl hydroxysultaine, and mixtures thereof;

b) from about 0.0035 g to about 0.7 g of a particulate selected from the group consisting of zinc pyrithione, zinc carbonate, ethylene glycol distearate, mica, titanium dioxide, and combinations thereof; and

c) from about 45 wt. % to about 78 wt. % water;

wherein;

1) the foam has a foam density of from about 0.04 g/cm³ to about 0.23 g/cm³; and

2) the foam has a plurality of bubbles comprising a bubble size distribution having a Sauter mean radius R₃₂ of from about 10 μ

m to about 60 μ

m as measured according to the Kruss Lather Analyzer Method.

2. The dosage of foam of claim 1, wherein the plurality of bubbles comprises a bubble size distribution having a Sauter mean radius R₃₂ of from about 10 μ

m to about 50 μ

m.

3. The dosage of foam of claim 1, wherein the plurality of bubbles comprises a bubble size distribution having a Sauter mean radius R₃₂ of from about 30 μ

m to about 50 μ

m.

4. The dosage of foam of claim 1, comprising a yield point of from about 15 Pa to about 100 Pa.

5. The dosage of foam of claim 1, wherein the volume of the dosage of foam is from about 10 g/cm³ to about 50 g/cm³.

6. The dosage of foam of claim 1, wherein the foam density is from about 0.06 g/cm³ to about 0.23 g/cm³.

7. The dosage of foam of claim 1, wherein the foam density is from about 0.06 g/cm³ to about 0.15 g/cm³.

8. The dosage of foam of claim 1, wherein the particulate comprises zinc pyrithione.

9. The dosage of foam of claim 1, wherein the plurality of bubbles comprises a bubble size distribution having a Sauter mean radius R₃₂ of from about 30 μ

m to about 45 μ

m.
