Benefits of technology

The patent describes a way to make hair curling products that use active agents to interact with keratin and nucleophiles in the hair to create long-lasting, smooth hair with increased strength and ease of combing. These products also prevent damage to the hair during the curling process caused by traditional methods that use lye or alkali-based agents. The use of these active agents allows for control over the level of curl and prevents damage to the hair. Traditional methods of curling hair can result in reduced strength and potential loss of hair through breakage, but this patent provides a new and improved way to curl and style hair with active agents.

Problems solved by technology

While lye and other alkali-based relaxers are highly effective at relaxing and straightening hair, they can result in reduction of hair strength and potential loss of hair through breakage.
These thiol or sulfur-containing reducing agents are foul smelling and, if not properly rinsed between the steps, can damage and / or brake hair.

Curling of Asian Hair

[0257]Composition of Formulations 1 and 2:

[0258]Formulation 1 contained 2 wt % NaOH and 2 wt % Bis-Aminopropyl Diglycol Dimaleate with the remainder of the formulation being made up of water.

[0259]Formulation 2 contained 4 wt % Bis-Aminopropyl Diglycol Dimaleate with the remainder of the formulation being made up of water.

[0260]Curling Procedure:

[0261]Formulation 1 was prepared immediately prior to use, applied to a swatch of Asian hair in a perm roller, and allowed to sit on the hair for 20 minutes. The hair sample was then thoroughly rinsed with room temperature water for 3 minutes and then blotted with a paper towel. Formulation 2 was added to the hair sample and allowed to sit for 20 minutes. The hair sample was then rinsed, removed from the roller, shampooed and conditioned, and allowed to air dry.

[0262]Curling Results: The hair retained a curl and exhibited a better condition, as compared to the hair prior to treatment, such as increased smoothness and shi...

Curling of Asian Hair

[0264]Composition of Formulations 1 and 2:

[0265]Formulation I contained 2 wt % NaOH with the remainder of the formulation being made up of water.

[0266]Formulation 2 contained 4 wt % Bis-Aminopropyl Diglycol Dimaleate with the remainder of the formulation being made up of water.

[0267]Curling Procedure:

[0268]Two swatches of Asian hair were rolled into perm rollers and each swatch was treated with Formulation 1 for 20 minutes. Both hair swatches were then rinsed for 3 minutes and blotted with a paper towel. One of the swatches was then treated with Formulation 2 for 20 minutes and the other swatch was treated with a 5 wt % acetic acid aqueous solution for 20 minutes. Both swatches were then rinsed, removed from the perm rollers, shampooed and conditioned, and allowed to air dry.

[0269]Curling Results:

[0270]The hair swatch neutralized with Formulation 2 demonstrated curl retention but was in worse condition than prior to the treatment and in significantly inferior co...

Curling of Caucasian Hair

[0272]Composition of Formulations 1 and 2:

[0273]Formulation 1 contained 2 wt % NaOH and 4 wt % Bis-Aminopropyl Diglycol Dimaleate with the remainder of the formulation being made up of water.

[0274]Formulation 2 contained 4 wt % Bis-Aminopropyl Diglycol Dimaleate with the remainder of the formulation being made up of water.

[0275]Curling Procedure:

[0276]Formulation 1 prepared immediately prior to use, applied to

[0277]Caucasian hair in a perm roller, and allowed to sit on the hair for 20 minutes. The hair sample was then thoroughly rinsed in room temperature water for 3 minutes and blotted with a paper towel. Formulation 2 was added to the hair sample and allowed to sit for 20 minutes. The hair sample was then rinsed, removed from the perm roller, shampooed and conditioned, and allowed to air dry.

[0278]Curling Results:

[0279]The treated hair retained curl and exhibited a better condition, as compared to the hair prior to treatment, such as increased smoothness a...

Abstract

Methods, formulations, and kits for curling and / or preventing damage in the curling of hair are disclosed herein. Treatment with one or more hydroxide-containing agents in combination with one or more active agents can reshape hair, without the need for sulfur-containing reducing agents. To impart curl to hair, the active agent(s) and the hydroxide-containing agent(s) are applied either as a combined formulation or as separate formulations which are applied simultaneously. Use of the active agent along with a hydroxide-containing agent allows the level of curl imparted to hair to be controlled, as compared to the natural amount of curl, if any, in the untreated hair.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. application Ser. No. 15 / 282,795, filed Sep. 30, 2016, which claims priority to U.S. Provisional Application Ser. No. 62 / 380,020, filed Aug. 26, 2016, and to U.S. Provisional Application Ser. No. 62 / 361,366, filed Jul. 12, 2016, the disclosures of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention generally relates to formulations and methods for curling hair, particularly for imparting and controlling a level of curl to the hair.BACKGROUND OF THE INVENTION[0003]Hair consists of many long, parallel chains of amino acids. These chains, or polymers, of amino acids are bound to each other via 1) hydrogen bonding, 2) salt bridges between acid and base groups, and 3) disulfide bonds.[0004]At alkaline pH, the disulfide bonds in hair can be broken (Dombrink et al., Chem Matters, 1983, page 8). For example, lye-based relaxers contain hydroxide ions...
