The chemical agents used in permanently altering the structure of the hair and the subsequent damage incurred using these agents and by extensive rinsing and manipulation of the hair during the shampooing further damages the hair and reduces the effectiveness of the smoothing and shaping technique while the relaxer or straightener is on the hair.
The invention is a low pH formula that may contain one or more acids, such as citric acid, maleic acid, boric acid, lactic acid, phosphoric acid, and the like.
In the present invention, citric acid is the preferred acid and used in a range of 0. The product may be formulated as a liquid, gel, suspension, colloid, paste, cream or lotion.
In this invention, the preferred embodiment formula is a liquid thickened to prevent dripping while styling the hair in the desired pattern. The invention is thickened to a preferred range of 1, to 3, cps, Brookfield, with hydroxyethylcellulose at a range of 0. The product further comprises a wetting agent to facilitate penetration of the product into the hair shaft. Suitable wetting agents include polysorbates and other mild nonionic surfactants, with a range of 0.
The optimum range is 1. An opacifier also may be used for aesthetic purposes; that is, to please the eye, it having a primary purpose of enhancing the visual detection of the color indicator on an alkaline medium. Opacifiers of any kind may be used, with the caution that too waxy an opacifier, a feature common to glyceryl stearate and emulsifying wax, especially if employed at higher concentrations, will prevent penetration of the invention formula into the hair shaft.
In the present invention, the preferred opacifier used is styrene acrylate copolymer in a range up to 8. The invention further comprises phenolphthalein as the color indicator to observe the presence of alkali. The range of phenothalein is 0. Laureth 23 is incorporated in a range of 0. This invention further comprises a conditioner that aids in combability, particularly during the neutralizing process. The preferred conditioner used in this invention is polyquaternium 32, a highly cationic modified polyacrylamide dispersed in mineral oil.
It is provided in the range up to 9. The conditioner does not interfere with the penetration of the formula in the preferred range. Fragrance also may be incorporated at a range of 0.
H do ethyl- cellulose 0. Laureth 23 0. Methyl- up to 1. The citric acid is added using moderate speed agitation when the hydration is completed. After the batch is clear and uniform, the pre-solubilized phenothalein in laureth 23 is added and mixed well. The opacifier is added to the batch with moderate agitation. The conditioner then is added. No heat is necessary to make this formula.
Fragrance is optional. If the conditioner is not used 0. The preconditioner comprises from 0. The preferred conditioner applied as a pretreatment comprises from 0. The preconditioner also comprises a new product hydrolyzed wheat protein containing oligosaccharides in which the daltons are high, to help keep the hair from breaking.
The preconditioner also comprises emulsifiers and surfactants, fragrance and preservatives that are a necessary vehicle for the conditioners to be delivered. The emulsifier preferrably is supplied at a range of 0. Suitable emulsifiers include waxy ester or wax or a fatty alcohol. The surfactants and solubilizers may be polysorbates or other mild nonionic surfactants.
Fragrance and preservatives are recommended in a range of 0. Component Range wt. Salts 1. The use of the preconditioner is necessary when the 0 neutralizing rinse does not contain the cationic conditioner that aids in the combability need for hair shaping during the neutralizing stage.
For severely damaged hair ends, particularly in the case of bleached and colored hair, the pretreatment is important to protect 5 the hair from the incidental contact with the relaxer directly and during the rinsing procedure. It also is highly effective in protecting the hair ends from acidic contact during the neutralizing process. Acidic products tend to cause slight swelling in normal virgin hair, and P more exaggerated swelling in bleached hair in the pH range of 2 to 3.
This is cited in G. Ramachandra Bhat, Rogerio M. Parreira, Elvin Lukenbach, Donald L. Harper and Helio C. The preconditioner is made in a similar manner to the neutralizing rinse, and comprises generally the same components. The emulsifying agents must be melted and added to the batch.
The process for effective neutralization comprises the following steps: If using the neutralizing rinse without the conditioner incorporated, or if the hair that has been previously processed is very damaged, overly porous, bleached or colored, the preconditioner is applied to the hair, and dried in with a cool dryer.
The alkaline relaxer is applied in the conventional manner, and the hair is processed to the desired straightness. The neutralizing rinse is applied to the hair, saturating first the freshly relaxed hair, and subsequently pulling out to the ends and reapplying the neutralizing rinse, if necessary, to fully wet the hair and to areas showing pink color, indicating alkaline conditions.
The hair is combed gently into the desired wave pattern or hair configuration. The hair may be combed straight, directed forward, backward, side to side, down, or round, as in the style termed "The Wrap", or placed on perm rods. The neutralizing rinse is allowed to sit on the hair for about 3 minutes.
During this time the bonds are forming in the desired configuration. Many bonds form as soon as the neutralizing rinse contacts the hair as evidenced by the sulfury odor. Experiments show that enough bonds are still active during the combing such that the hair is permanently structured in the arrangement combed in at the time of neutralization. The amount of neutralizing rinse applied varies with the length of the hair also. The recommended amounts of neutralizing rinse to be applied are as follows: about 1 fluid oz.
In the salon testing program the entire relaxer system was used. Nine people experienced some level of scalp sensation, for example, itching, tingling, and in a case, burning, while having the relaxer applied during the smoothing process. The neutralizing rinse was applied directly to the sensation area on the scalp. The sensation stopped immediately. In the one case of burning, the sensation decreased in strength from a burning sensation to an itching to tingling sensation.
Scalp irritation from the relaxer is very common, particularly if the scalp has been rubbed or scratched close to the time of relaxing. The patrons in the salon must inform the hairdresser at the first sign of itching. If the neutralizer is applied directly to the itching spot, the sensation will end, and the alkali from the relaxer neutralized. The best way to apply the neutralizing rinse to insure precision is via a small orifice in a pointed cap on a low density plastic bottle, as in the hair color applicator bottles commonly used in the salons.
In the salon, eight people were successfully given a permanent wave pattern in the direction of the desired style. Shorter hair yielded a wave pattern that normally would have to have been mechanically produced with styling aids. One patron shampooed 3 times in 4 days and the desired wave pattern that was placed in at the time of neutralization was still present. The wave pattern in one model was so strong in direction that it had to be mechanically set to get another pattern.
The set was effective. The wave that was set in during the neutralization gave excellent appearance and body. One model was particularly happy with the feel of her scalp after the process. One model who experienced burning on the scalp during the relaxer process was subsequently treated with the neutralizing rinse using phenolphthalein solubilized in alcohol, which stopped the intensity of the sensation. However during the application of the neutralizing rinse, in the same area a stinging sensation occurred.
The alcohol in which the phenolphthalein was solubilized caused the unpleasant sensation. Therefore, laureth 23 was used in place of alcohol to solubilize the phenolphthalein to avoid this problem. The use of conditioner, namely that of polyquaternium 23, is a preferred option in the process.
When no preconditioner was used, and the neutralizer did not contain the conditioner, on a person with a hair tint in her hair, the hair ends became soft and sticky.
