Embodiment 1

[0051] This embodiment provides a hair dye using nano-silver as a coloring component, which contains only one agent, including the following mass percentages:

[0052] 5-40% of nano-silver after silver ion reduction treatment;

[0053] 1-5% thickener;

[0054] 2-10% dispersant; and

[0055] For the rest of the water, the sum of the percentages of each component is equal to 100%;

[0056] The pH of the hair dye is 3-11.

[0057] Preferably, the particle size of the nano silver is 1-100 nm.

[0058] Preferably, the reducing agent used in the silver ion reduction treatment is a plant reducing agent or a chemical reducing agent.

[0059] Preferably, the plant reducing agent includes: one or two of gallnut, tea, coffee, chrysanthemum, coriander, eucalyptus, pepper, safflower, henna, geranium, persimmon, mahogany, sweet orange and banana The natural reducing agent based on polyphenols extracted from the leaves, flowers or seed parts of the above plants.

[0060] The chemical reducing agent inclu...

Embodiment 2

[0067] This embodiment provides a method for preparing a hair dye using nano silver as a coloring component, such as the hair dye using nano silver as a coloring component in Example 1. The method includes the following steps:

[0068] Use plant reducing agent or chemical reducing agent to perform silver ion reduction treatment on nano silver particles;

[0069] The nano-silver embedded polymer wall material after silver ion reduction treatment;

[0070] Mix 5-40% of the embedded polymer wall material with silver ion reduction treatment of nano silver, 1-5% of thickener, 2-10% of dispersant and the balance of water, and stir it evenly Get creamy or gel-like hair dye. For example, dissolve 5-40% of the nanosilver embedded in the polymer wall material after silver ion reduction treatment in 40-90% water; then disperse 1-2% of the thickener xanthan gum evenly in 2- 5% dispersant in propylene glycol; adjust the pH of the solution containing nano silver particles and slowly pour it into...

example 1

[0094] The hair dye components are:

[0095] Nano silver 5-40%, xanthan gum 1-5%, propylene glycol 2-10%, appropriate amount of pH regulator and preservative isothiazolinone.

[0096] The preparation steps of the hair dye are as follows: first crush the dried tea leaves into powder, mix the tea powder and distilled water at a solid-liquid ratio of 1:25, then heat and extract, then cool the extract and filter it through filter paper to dilute the filtrate to 5% spare. The silver nitrate particles are dissolved in distilled water and prepared as a solution with a concentration of 10 mmol / L for use. Mix 20g of diatomaceous earth with 1000mL of the above-mentioned diluted tea extract and stir for 1h. The disc-shaped diatomaceous earth has multiple pores inside and on the surface of the particles. This process is beneficial to the active substances in the tea extract such as tea polyphenols. Adsorbed on diatomaceous earth, the filter residue was stirred with 400 mL of 10mmol / L silver ...

Abstract

The invention, which relates to the technical field of cosmetic industry of fine chemical engineering, discloses a hair dyeing agent taking nano-silver as a coloring component and a preparation methodthereof. The hair dyeing agent comprises the following components, by mass: 5-40% of nano-silver subjected to silver ion reduction treatment, 1-5% of a thickening agent, 2-10% of a dispersant, and the balance being water. The sum of the content percentages of the components is equal to 100% and the pH value of the hair dyeing agent is 3-11. According to the invention, the hair is colored by utilizing the local surface plasma resonance characteristic of the nano-silver particles, the dyeing rate is high, the color uniformity is good, the dyeing stability and the color retention washable performance are excellent, and the hair dyeing operation steps are simple.

Description

Technical field [0001] The invention relates to the technical field of fine chemical cosmetics industry, in particular to a hair dye using nano silver as a coloring component and a preparation method. Background technique [0002] Hair dyes are currently the fastest growing category of cosmetics. Traditional hair dyes are mostly chemically synthesized dyes, such as azo dyes-aromatic amine dyes. These dyes are the fastest and have the best effect. However, long-term use of azo dyes may cause cancer. At the same time, long-term use of this chemically synthesized hair dye can also cause skin allergic reactions and chronic accumulation poisoning. Pregnant women may cause fetal malformations. [0003] Therefore, with the improvement of people’s safety awareness, most of the natural dye hair dyes are now used to replace the above-mentioned chemically synthesized hair dyes. Natural dye hair dyes are usually colored with plant dyes, but plant dyes have defects such as poor color fastness ...
