Description

Direct hair dyeing product containing cationic cassia seed gum and application thereof

Technical Field

The invention belongs to the field of daily chemicals, and particularly relates to a direct hair dyeing product containing cationic cassia seed gum and application thereof.

Background

Hair dye products are a cosmetic for dyeing hair, and hair dyeing is a fashion option for people.

Hair dye products are generally classified into two main categories, oxidative and non-oxidative. Oxidative hair dye products whose ingredients are mainly amines or phenolic compounds, such as p-phenylenediamine, p-aminophenol, hydroquinone, toluene 2,5 diamine, m-aminophenol, o-phenylenediamine, resorcinol and p-methylaminophenol, which are carcinogenic and therefore not contacted by the body frequently; at the same time, amine or phenol compounds can cause certain stimulation to hair follicles and inflammation, so that hair thinning and hair follicle atrophy are caused, and once the hair follicles are necrotized, permanent alopecia is caused. In addition, the oxidative hair dye has a pungent smell, and the hair dyeing process is unpleasant. The dyeing process is relatively long, which can be prohibitive for consumers. The oxidation type hair dyeing product is generally used in a salon, cannot be operated by itself, has complicated steps, is limited in use scene for consumers, and cannot be used for dyeing hair by itself. The non-oxidative hair dyeing products are also called direct hair dyeing products, the components of the non-oxidative hair dyeing products are mainly pigments and heavy metal salts, and the hair dyeing products are characterized in that although the use is convenient, the scene is flexible, and the self-operation is realized, a series of problems of poor coloring effect, poor color durability and the like of the common hair dyeing products cannot be met, and the basic requirements of bright color and slow fading of consumers, especially young-generation consumers, can not be met.

Hair consists of Mao Biaoceng (scaly layer), cortical and medulla layers. The dyeing mechanism of the oxidative hair dyeing product is that the scale layer of the hair is opened through ammonia or phenols, so that the hair is decolorized, namely commonly known as bleaching, and then the pigment in the hair dye is permeated, thereby achieving the effect of dyeing the hair. The hair dye has the greatest advantages of good coloring effect, obvious defects and hair injury, and the damage to the medulla layer can be caused once the scale layer is opened because the scale layer needs to be opened.

Polysaccharide is a macromolecular polysaccharide composed of a plurality of glucose molecules, and is widely found in nature. Polysaccharides have a variety of biological activities and pharmacological effects, and have been widely used in the medical, nutritional, health care fields, etc., and in addition, as thickeners, conditioning polymers, auxiliary deposition agents, and film formers for personal care products. Cationic derivatives of guar gum and galactomannan have been successfully used in conditioning shampoos to enhance deposition of silicone oil onto hair in combination with silicone products to improve dry combing, wet combing performance, hair feel, shine and manageability, but have not been reported for coloring hair.

Therefore, research and development of a non-oxidative hair dyeing product which does not contain ammonia or phenol compounds, has good coloring effect and slow fading, has flexible use scene and simple operation is imperative.

4.2 experiments on dyeing the hair

The experimental method comprises the following steps: placing the material body to be dyed on the tail of the hair bundle at a distance of about 3-4cm from the top end of the hair bundle, uniformly placing 3g of material body on each hair bundle, brushing 15 times until the hair bundle spreads uniformly, standing for 30 minutes, then washing the hair bundle cleanly with clear water, and drying the hair bundle at normal temperature. The results of the dyeing experiment are shown in FIG. 4. Wherein, from left to right, the number 1 is the hair dye product of the embodiment, and the number 2 is the commercial direct hair dye.

As can be seen from FIG. 4, the coloring effect of the dyeing product of this example is dark red, while the commercially available direct hair dye is light, and the coloring effect of the hair dye product of the present invention is better.

4.3 decolorizing experiments

With commercially available direct hair dyes and the direct hair dyes protected by the patent, the dyed hair tresses are photographed, and then the fading experiment is started.

Fading experiment: soaking hair bundles in 10% sodium laurylsulfate solution for 5min, kneading hair bundles 20 by hand from beginning to end, washing with water, and blow drying with a blower. Repeating the above operation for 7 times, and drying to obtain the fading effect. Fading test results fig. 5. Wherein, from left to right, the number 1 is the hair dye product of the embodiment, and the number 2 is the commercial direct hair dye.

As can be seen from fig. 5, the dyeing product (right side) of this example, after washing with sodium lauryl sulfate, has a darker dyeing color than the commercial direct hair dye, and almost corresponds to the dyeing color of step 4.2, indicating that the coloring effect of the composition or hair dye product of the present invention is better.

4.3 aging test

Accelerated aging test: the hair dye product obtained in this example was subjected to aging test at-10, 25 and 45 ℃ for 3 months, and the pH and viscosity of the product were measured on a fixed date for each month to observe the change in appearance. The statistical results are shown in Table 9.

Appearance: cream (characteristic color), uniform and particle-free
