Method and composition for waving and straightening hair
View Patent ↗An improved process and composition for straightening or waving hair is achieved combining ammonium bisulfite and ethanolamine sulfite in a single mixture which is maintained at a pH of between about 6.5 and 8.0. By employing the present invention, long lasting, waved or straightened hair is attained. Furthermore, using the hair waving/straightening composition and method of the present invention, the desired waving and/or straightening of hair fiber is achieved in a single step, without the need for a separate application of an oxidizing or neutralizing agent.
1. A hair waving/straightening composition consisting of
A. from 0.05% to 3.0% by weight based upon the weight of the entire composition of hydroxyethylcellulose;
B. from 7% to 11% by weight based upon the weight of the entire composition of ammonium bisulfite;
C. from 1% to 5% by weight based upon the weight of the entire composition of ethanolamine sulfite;
D. from 1% to 3% by weight based on the weight of the entire composition of the urea;
E. from 1.5% to 4% by weight based upon the weight of the entire composition of a nonionic surfactant;
F. an alkali agent in sufficient quantities to obtain the desired pH
G. from 0.5% to 1% by weight based upon the weight of the entire composition of propylene glycol;
H. from 0.5% to 1% by weight based upon the weight of the entire composition of glycerol;
I. from 0.1% to 1% by weight based upon the weight of the entire composition of isopropanol;
J. from 0.1% to 0.5% by weight based upon the weight of the entire composition of ethoxydiglycol;
K. from 0.1% to 1% by weight based upon the weight of the entire composition of quaternium-75;
L. from 0.025% to 0.05% by weight based upon the weight of the entire composition of cinannamidopropyldimmonium chloride;
M. from 0.1% to 0.5% by weight based upon the weight of the entire composition of hydrolyzed keratin PG-propyl methylsilanediol; and
N. from 0.4% to 0.9% by weight based upon the weight of the entire composition of at least one perfume.
2. The hair waving/straightening composition defined in claim 1 , wherein said composition is formulated as comprising one selected from the group consisting of liquids and foams.
3. A system for waving or straightening hair comprising:
A. a composition; according to claim 1 and
B. a container constructed for retaining said composition therein, with said container incorporating a non-aerosol finger pump foam dispenser;
whereby said composition is dispensed from said container as a foam product.
4. The hair waving/straightening system defined in claim 3 , wherein said non-aerosol finger pump foam dispenser is further defined as comprising an F2 finger pump foamer incorporating an extended dispenser tip.
5. The hair waving/straightening system defined in claim 4 , wherein the foam output from said container for each stroke ranges between about 14.8 and 18.8 mm or 0.75 and 1.5 g.
6. A method for waving hair comprising the steps of
A. winding the hair fibers onto tools selected from the group consisting of rods, rollers, and curlers;
B. dampenning the prewrapped hair fibers;
C. applying a waving composition to the dampened, hair wound on the tools, said waving composition consisting of:
A. from 0.05% to 3.0% by weight based upon the weight of the entire composition of hydroxyethylcellulose;
B. from 7% to 11% by weight based upon the weight of the entire composition of ammonium bisulfite;
C. from 1% to 5% by weight based upon the weight of the entire composition of ethanolamine sulfite;
D. from 1% to 3% by weight based on the weight of the entire composition of the urea;
E. from 1.5% to 4% by weight based upon the weight of the entire composition of a nonionic surfactant;
F. an alkali agent in sufficient quantities to obtain the desired pH
G. from 0.5% to 1% by weight based upon the weight of the entire composition of propylene glycol;
H. from 0.5% to 1% by weight based upon the weight of the entire composition of glycerol;
I. from 0.1% to 1% by weight based upon the weight of the entire composition of isopropanol;
J. from 0.1% to 0.5% by weight based upon the weight of the entire composition of ethoxydiglycol;
K. from 0.1% to 1% by weight based upon the weight of the entire composition of quaternium-75;
L. from 0.025% to 0.05% by weight based upon the weight of the entire composition of cinannamidopropyldimmonium chloride;
M. from 0.1% to 0.5% by weight based upon the weight of the entire composition of hydrolyzed keratin PG-propyl methylsilanediol; and
N. between about 0.4% and 0.9% by weight based upon the weight of the entire composition of at least one perfume
D. allowing the waving composition to dissipate into the hair fibers within five minutes;
E. capping the hair and allowing the waving lotion to process for a period of time ranging between about 15 and 60 minutes;
F. removing the tools from the hair and rinsing the hair for about five minutes; and
G. styling the hair to achieve the desired appearance;
whereby waved hair is achieved without requiring the use of neutralization/oxidant compositions.
7. The method for waving hair defined in claim 6 , wherein the capped hair is allowed to process at room temperature.
8. The method for waving hair defined in claim 6 , wherein the capped hair is processed under a preheated hair dryer maintained at a temperature ranging between about 49° C. and 55° C.
9. The method defined in claim 6 , wherein said composition is further defined as being retained in a container having a non-aerosol finger pump foam dispenser and said composition is dispensed and applied to the hair as a foam.
