Abstract
Abstract There is provided a composition for the frosting of hair comprised of an intimate mixture of particulate persulfate salts and alkaline silicates dispersed in an anhydrous organic carrier, the anhydrous organic carrier being sufficiently hydrophobic to retard absorption of atmospheric moisture and provided in a quantity sufficient to coat the particles to prevent persulfate decomposition in the presence of moist air. The carrier is sufficiently hydrophilic so as to be emulsifiable in an aqueous hydrogen peroxide solution to form with a thickener a viscous hair frosting emulsion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
84 words
A bleach composition for frosting of hair comprising an intimate mixture of at least one particulate persulfate salt and at least one particulate alkali silicate in an anhydrous organic carrier base provided in an amount sufficient to coat the particles present and form a mixture of paste to cream in consistency, the organic carrier base being sufficiently hydrophobic to substantially prevent absorption of atmospheric moisture by the mixture, and sufficiently hydrophilic to enable dispersion of the mixture in an aqueous solution of hydrogen peroxide.
Claim 2
Dependent Claim
84 words
A bleach composition for frosting of hair comprising an intimate mixture of at least one particulate persulfate salt and at least one particulate alkali silicate in an anhydrous organic carrier base provided in an amount sufficient to coat the particles present and form a mixture of paste to cream in consistency, the organic carrier base being sufficiently hydrophobic to substantially prevent absorption of atmospheric moisture by the mixture, and sufficiently hydrophilic to enable dispersion of the mixture in an aqueous solution of hydrogen peroxide.
Claim 3
Dependent Claim
23 words
A bleach composition for frosting of hair as claimed in claim 1 in which a thickener is present as part of the mixture.
Claim 4
Dependent Claim
37 words
A bleach composition as claimed in claim 1 in which the anhydrous organic carrier base is present in an amount of from about 30 to about 70% by weight based on the total weight of the mixture.
Claim 5
Dependent Claim
37 words
A bleach composition as claimed in claim 2 in which the anhydrous organic carrier base is present in an amount of from about 30 to about 70% by weight based on the total weight of the mixture.
Claim 6
Dependent Claim
37 words
A bleach composition as claimed in claim 1 in which the anhydrous organic carrier base is present in an amount of from about 40 to about 60% by weight based on the total weight of the mixture.
Claim 7
Dependent Claim
37 words
A bleach composition as claimed in claim 3 in which the anhydrous organic carrier base is present in an amount of from about 40 to about 60% by weight based on the total weight of the mixture.
Claim 8
Dependent Claim
106 words
A bleach composition for frosting of hair which comprises an intimate mixture of at least one particulate persulfate salt and at least one alkali silicate in an anhydrous organic carrier base which includes at least one substantially hydrophobic organic compound and at least one substantially hydrophilic organic compound, said organic base being present in an amount sufficient to coat the particles present and form a mixture of paste to cream in consistency, and sufficiently hydrophobic to substantially prevent absorption of atmospheric moisture by the mixture and sufficiently hydrophilic to enable dispersion of the mixture in an aqueous solution of hydrogen peroxide, said mixture including a thickener.
Claim 9
Dependent Claim
106 words
A bleach composition for frosting of hair which comprises an intimate mixture of at least one particulate persulfate salt and at least one alkali silicate in an anhydrous organic carrier base which includes at least one substantially hydrophobic organic compound and at least one substantially hydrophilic organic compound, said organic base being present in an amount sufficient to coat the particles present and form a mixture of paste to cream in consistency, and sufficiently hydrophobic to substantially prevent absorption of atmospheric moisture by the mixture and sufficiently hydrophilic to enable dispersion of the mixture in an aqueous solution of hydrogen peroxide, said mixture including a thickener.
Claim 10
Dependent Claim
37 words
A bleach composition as claimed in claim 7 in which the anhydrous organic carrier base is present in an amount of from about 30 to about 70% by weight based on the total weight of the mixture.
Claim 11
Dependent Claim
37 words
A bleach composition as claimed in claim 7 in which the anhydrous organic carrier base is present in an amount of from about 40 to about 60% by weight based on the total weight of the mixture.
