Hair coloring compositions and methods thereof

Abstract

A hair coloring composition that includes about 5 to 25 wt. % of a first monosaccharide having 2 to 4 carbon atoms, up to about 10 wt. % of a second monosaccharide having 2 to 4 carbon atoms, about 0.1 to 5 wt. % of a surfactant, and about 0.1 to 5 wt. % of a delivery agent, each based on a total weight of the hair coloring composition. A method for coloring hair, that involves applying the hair coloring composition onto the hair, and optionally applying heat to the hair at a dyeing temperature of 30 to 205° C.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to hair coloring compositions and methods of coloring hair using the hair coloring compositions.Discussion of the Background[0002]The “background” description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description which may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present invention.[0003]The appearance of gray hair typically begins around the age of 30 and is a top hair care concern for both men and women. Graying hair may lead to an emotional reaction including feelings of loss of strength, loss of youthfulness, and loss of vitality, particularly so for women with graying hair. Therefore many consumers choose to cover up gray hair by full coverag...

AI Technical Summary

Benefits of technology

[0010]These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that the following hair coloring compositions can be easily applied at home with short application times to provide a deep, rich, long lasting, multi-tonal color, while minimizing staining of the scalp and without the use of harsh oxidizing agents.

Problems solved by technology

Graying hair may lead to an emotional reaction including feelings of loss of strength, loss of youthfulness, and loss of vitality, particularly so for women with graying hair.

However, technology limitations often make the resulting dyed hair appear flat or without preferred multi-tones, resulting in an unnatural look.

Moreover, such box colors or spray systems can be difficult to apply and may result in unwanted staining of the scalp.

The use of salon services, while generally providing a more natural looking, multi-tonal coloration, can be cost and time prohibitive for many consumers and is perceived to cause hair damage due to repeated and prolonged exposure to chemical treatments.

Further, many consumers are generally skeptical of hair dyes due to the perceived effects of harsh chemicals, such as oxidizing agents, on hair structure and general follicle health.
