Abstract
Abstract This invention is concerned with the pretreatment of hair on the human head, preceding shampooing the hair with anionic type hair shampoos, and with compositions for effecting such pretreatment, to obtain highly improved manageability of the hair after shampooing and with improved fullness, compability and other desired properties of the hair. The pretreatment compositions utilize readily water-soluble quaternary ammonium compounds, particularly in combination with certain agents, notably polyethylenimines and N-ethanolacetamide, and desirably together with various supplemental ingredients.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
59 words
A method of treating hair to improve the manageability thereof, which comprises initially contacting the hair with a dilute aqueous composition containing a water-soluble quaternary ammonium compound containing at least one long chain aliphatic hydrocarbon radical directly or indirectly linked to a quaternary nitrogen atom in said quaternary ammonium compound, and then shampooing the hair with an anionic shampoo.
Claim 2
Independent Claim
59 words
A method of treating hair to improve the manageability thereof, which comprises initially contacting the hair with a dilute aqueous composition containing a water-soluble quaternary ammonium compound containing at least one long chain aliphatic hydrocarbon radical directly or indirectly linked to a quaternary nitrogen atom in said quaternary ammonium compound, and then shampooing the hair with an anionic shampoo.
Claim 3
Dependent Claim
58 words
The method of claim 1, in which the quaternary ammonium compound has the formula ##STR6## wherein R 1 is C 8 -C 18 alkyl; R 2 is C 1 -C 3 alkyl; R 3 is C 1 -C 3 alkyl or benzyl; R 4 is C 1 -C 3 alkyl or benzyl; and A is an innocuous anion.
Claim 4
Dependent Claim
27 words
The method of claim 1, in which the quaternary ammonium compound is a N-(acylcolaminoformylmethyl)-pyridinium chloride, where acyl is a C 8 -C 18 aliphatic hydrocarbon acyl radical.
Claim 5
Dependent Claim
13 words
The method of claim 3, in which the acyl radical is predominately lauroyl.
Claim 6
Dependent Claim
16 words
The method of claim 1, in which the quaternary ammonium compound is a diquaternary ammonium compound.
Claim 7
Dependent Claim
41 words
The method of claim 1, in which the dilute aqueous composition containing the quaternary ammonium compound also contains a member selected from the group consisting of N-ethanolacetamide and a fatty acid ethanolamide in which the fatty acid comprises predominately lauric acid.
Claim 8
Dependent Claim
29 words
The method of claim 1, in which the dilute aqueous composition containing the quaternary ammonium compound also contains polyethylenimine having a molecular weight between about 10,000 and about 70,000.
Claim 9
Dependent Claim
24 words
The method of claim 6, in which the dilute aqueous composition also contains polyethylenimine having a molecular weight between about 10,000 and about 70,000.

The method of claim 1, in which the dilute aqueous composition also includes N-ethanolacetamide and polyethylenimine having a molecular weight in the range of about 10,000 to about 70,000, and in which said solution contains the stated ingredients in approximately the following proportions by weight of said composition: Water: 70 to 90% Quaternary ammonium compound: 0.5 to 4% N-ethanolacetamide: 3 to 18% Polyethylenimine: 0.5 to 5%.
Claim 11
Dependent Claim
72 words
A composition for pretreatment of hair prior to shampooing said pretreated hair with an anionic shampoo, said composition comprising a major proportion of water, and minor proportions of a readily water-soluble quaternary ammonium compound containing at least one long chain aliphatic hydrocarbon radical directly or indirectly linked to a quaternary nitrogen atom in said quaternary ammonium compound, and polyethylenimine having a molecular weight in the range of about 10,000 to about 70,000.
Claim 12
Dependent Claim
72 words
A composition for pretreatment of hair prior to shampooing said pretreated hair with an anionic shampoo, said composition comprising a major proportion of water, and minor proportions of a readily water-soluble quaternary ammonium compound containing at least one long chain aliphatic hydrocarbon radical directly or indirectly linked to a quaternary nitrogen atom in said quaternary ammonium compound, and polyethylenimine having a molecular weight in the range of about 10,000 to about 70,000.
Claim 13
Dependent Claim
36 words
The composition according to claim 10, which also includes a minor proportion of a member selected from the group consisting of N-ethanolacetamide and a fatty acid ethanolamide in which the fatty acid comprises predominately lauric acid.
Claim 14
Dependent Claim
