Abstract

The hair is protected from damage by chemical agents, e.g. in bleaching, by either pretreatment with, or concurrent use of a protective agent and the damaging chemical. The protective agents disclosed are organic compounds containing two or more polar groups, e.g. carboxyl groups, which are separated by at least 15 atoms the majority of which are carbon atoms and preferably containing a cyclic moiety of at least 5 atoms, e.g. the dimer of linoleic acid.

Claims

1. In a process for treating hair comprising subjecting hair to an aqueous hair damaging composition, the improvement comprising reducing the degree of hair damage by applying to the hair prior to or concurrently with subjecting the hair to said hair damaging composition, an aqueous composition containing protective agent in an amount effective to reduce the degree of hair damage, said protective agent being compatible and dispersible in the aqueous composition by which it is applied to the hair;

said protective agent being an organic compound containing at least two polar groups separated by a chain of at least 15 atoms, a majority of which are carbon atoms, and which contains a cyclic moiety;

said polar groups selected from the class consisting of carboxyl;

carboxyl salt in which the salt forming group is a metal, ammonia or an amine;

hydroxyl;

amino;

substituted amino wherein the substituents are aliphatic or aromatic hydrocarbon radicals of 1 to 12 carbon atoms, or said substituents taken together form a 3 to 6 membered carbocyclic or heterocyclic ring with the amino nitrogen;

amido, substituted amido wherein the substituents are aliphatic or aromatic hydrocarbon radicals of 1 to 12 carbon atoms, or said substituents taken together form a 3 to 6 membered carbocyclic or heterocyclic ring with the amido nitrogen, quaternary ammonium wherein the nitrogen substituents are alkyl of 1 to 6 carbon atoms;

lower alkyl ester;

sulfate;

sulfonate;

phosphate;

phosphonate; and

polar groups containing further substituents in said alkyl, aliphatic or aromatic hydrocarbon radicals selected from the class defined above.

2. Process of claim 1 in which said protective agent is selected from the group consisting of esters and polyesters of cycloaliphatic or aromatic polycarboxylic acids containing at least one 5 to 7 carbon ring and a hydroxy compound comprising a polyoxyalkylene ether containing 2 to 30 oxyalkylene units in which the alkylene radical contains 2 to 4 carbon atoms.

3. The process of claim 1 in which said hair damaging composition is a hair bleaching composition.

4. The process of claim 1 in which said carboxyl salt polar group is a sodium, potassium, ammonium, or triethanolamine salt.

5. The process of claim 1 in which hair is treated with a hair damaging bleaching composition subsequent to the step of subjecting the hair to said aqueous composition containing protective agent.

6. An improved aqueous hair bleaching composition consisting essentially of a hair damaging hair bleaching composition and protective agent compatible and dispersible therein, in an amount effective to reduce the amount of damage to the hair;

said improved hair bleach composition causing reduced hair damage when used for bleaching hair compared to the composition without the protective agent;

said protective agent being an organic compound containing at least two polar groups separated by a chain of at least 15 atoms, a majority of which are carbon atoms, and which contains a cyclic moiety;

said polar groups selected from the class consisting of carboxyl;

carboxyl salt;

hydroxyl;

amino;

substituted amino wherein the substituents are aliphatic or aromatic hydrocarbon radicals of 1 to 12 carbon atoms, or said substituents taken together from a 3 to 6 membered carbocyclic or heterocyclic ring with the amino nitrogen;

amido;

substituted amido wherein the substituents are aliphatic or aromatic hydrocarbon radicals of 1 to 12 carbon atoms, or said substituents taken together form a 3 to 6 membered carbocyclic or heterocyclic ring with the amido nitrogen;

quaternary ammonium wherein the nitrogen substituents are alkyl of 1 to 6 carbon atoms;

lower alkyl ester;

sulfate;

sulfonate;

phosphate;

phosphonate; and

polar groups containing further substituents in said alkyl, aliphatic or aromatic hydrocarbon radicals selected from the class of polar groups defined above.

7. The composition of claim 6 in which the carboxyl salt polar group is a salt of sodium, potassium, ammonium or triethanolamine.

8. Composition of claim 6 in which said protective agent is selected from the group consisting of esters and polyesters of cycloaliphatic or aromatic polycarboxylic acids containing at least one 5 to 7 carbon ring and a hydroxy compound comprising a polyoxyalkylene ether containing 2 to 30 oxyalkylene units in which the alkylene radical contains 2 to 4 carbon atoms.
