Abstract
Abstract An improved strong foaming toothpaste containing gelatin, a gelatinous eggwhite product or a mixture thereof and at least one surfactant. The gelatin or gelatinous eggwhite product makes it possible to reduce the surfactant content, thereby providing a toothpaste which avoids the adverse effects a high content of surfactant has on the mouth mucous membrane. About 1 to 2.5% by weight of surfactant and 1 to 10% by weight of gelatin, a gelatinous eggwhite product, or mixture thereof, can be used in the toothpaste.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
In a toothpaste with high foaming ability containing at least one surfactant, the improvement comprising including in the toothpaste about 1 to 10% by weight of a gelatin soluble in cold water, a gelatinous eggwhite product soluble in cold water, or a mixture thereof, about 1 to 2.5% by weight of surfactant, and a sufficient amount of a foam coloring agent for optical cleaning control so that at the beginning of brushing of the teeth a colored foam is produced which after at least 20 seconds of brushing shows foam decolorization by a brightness difference ΔL in the range of about 10 to 30 with the brightness L=0 for black and L=100 for white, and the foam is subsequently decolored to white or a faintly colored condition.
Claim 2
Dependent Claim
127 words
In a toothpaste with high foaming ability containing at least one surfactant, the improvement comprising including in the toothpaste about 1 to 10% by weight of a gelatin soluble in cold water, a gelatinous eggwhite product soluble in cold water, or a mixture thereof, about 1 to 2.5% by weight of surfactant, and a sufficient amount of a foam coloring agent for optical cleaning control so that at the beginning of brushing of the teeth a colored foam is produced which after at least 20 seconds of brushing shows foam decolorization by a brightness difference ΔL in the range of about 10 to 30 with the brightness L=0 for black and L=100 for white, and the foam is subsequently decolored to white or a faintly colored condition.
Claim 3
Dependent Claim
128 words
In a toothpaste with high foaming ability containing at least one surfactant, the improvement comprising including in the toothpaste about 1 to 10% by weight of a cold water soluble gelatin hydrolyzate alone or in admixture with a gelatinous eggwhite product soluble in cold water, about 1 to 2.5% by weight of surfactant, and a sufficient amount of a foam coloring agent for optical cleaning control so that at the beginning of brushing of the teeth a colored foam is produced which after at least 20 seconds of brushing shows foam decolorization by a brightness difference ΔL in the range of about 10 to 30 with the brightness L=0 for black and L=100 for white, and the foam is subsequently decolored to white or a faintly colored condition.
Claim 4
Dependent Claim
128 words
In a toothpaste with high foaming ability containing at least one surfactant, the improvement comprising including in the toothpaste about 1 to 10% by weight of a cold water soluble gelatin hydrolyzate alone or in admixture with a gelatinous eggwhite product soluble in cold water, about 1 to 2.5% by weight of surfactant, and a sufficient amount of a foam coloring agent for optical cleaning control so that at the beginning of brushing of the teeth a colored foam is produced which after at least 20 seconds of brushing shows foam decolorization by a brightness difference ΔL in the range of about 10 to 30 with the brightness L=0 for black and L=100 for white, and the foam is subsequently decolored to white or a faintly colored condition.
