## Abstract

Oxyethylene functional organosilane compounds are used as foam boosters in hair shampoo compositions. The oxyethylene functional organosilane compounds having the formula RSiR'.sub.3 in which R is the radical --O(CH.sub.2 CH.sub.2 O).sub.x R"; R' is an R group or an alkyl group having one to six carbon atoms; R" is an endblocking radical such as hydrogen, an alkyl group having one to six carbon atoms, or an aryl group; and x is an integer having a value of six to thirty.

## Claims

### Claim 1

In a method of boosting foam in an aqueous media containing an emulsifying agent selected from the group consisting of an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, and mixtures thereof, by adding to the aqueous media a foam boosting effective amount of a foam boosting compound, the improvement comprising the foam boosting compound being an oxyethylene functional organosilane compound having the formula RSiR'.sub.3 in which R is the radical --O(CH.sub.2 CH.sub.2 O).sub.x R"; R' is an R group or an alkyl group having one to six carbon atoms; R" is a radical selected from the group consisting of hydrogen, an alkyl group having one to six carbon atoms, and an aryl group; and x is an integer having a value of six to thirty.

### Claim 2 (depends on 1)

A method according to claim 1 in which the aqueous media includes 10 to 80 percent by weight of water, 10 to 50 percent by weight of a mixture of surfactants; and 0.1 to 10 percent by weight of a cationic conditioning agent.

### Claim 3 (depends on 2)

A method according to claim 2 in which the aqueous media includes 0.1 to 10 percent by weight of the oxyethylene functional organosilane compound.

### Claim 4 (depends on 1)

A method according to claim 1 in which the aqueous media includes 30 to 50 percent by weight of water, 15 to 30 percent by weight of a mixture of surfactants; and 3 to 5 percent by weight of a cationic conditioning agent.

### Claim 5 (depends on 4)

A method according to claim 4 in which the aqueous media includes 3 to 5 percent by weight of the oxyethylene functional organosilane compound.

### Claim 6 (depends on 1)

A method according to claim 1 in which the value of the integer x is from twelve to twenty.

### Claim 7 (depends on 6)

A method according to claim 6 in which the oxyethylene functional organosilane compound has the formula (CH.sub.3).sub.2 Si›O(CH.sub.2 CH.sub.2 O).sub.16 H!.sub.2.
