The total content of the saccharide derivative type surfactant and the amino acid type surfactant is 0.01% by weight to 10% by weight based on the total weight of the dyeing composition; the content of the dye is 0.01% by weight to 10% by weight; The content is from 80% by weight to 99.98% by weight. The amino acid type surfactant of the present invention is formed by reacting an amino acid compound with a C ₂ -C ₂₂ fatty acid compound to have an amphoteric structure, which can improve the dispersion and phase between polarity and non-polarity. Capacitance. The amino acid type surfactant of the invention has good low toxicity, dispersibility and biocompatibility, and can be widely applied to foods, cosmetics and the like. In addition, the amino acid type surfactant of the present invention has good biodegradability, does not cause pollution and damage to the environment, and can be widely used in industrial applications, for example, dyeing and finishing auxiliaries, detergents, etc. The saccharide derivative type surfactant according to the present invention is a biodegradable surfactant having a saccharide structure prepared from a polyol glycoside and an alkyl epoxidized propyl ether; the polyol saccharide The system is prepared from a sugar and a polyol to form a polyol glycoside; the alkyl epoxypropyl ether is formed by reacting a C ₄ -C ₃₀ fatty alcohol with epichlorohydrin, and then the polyol is glycoside The body is reacted with an alkyl glycidyl ether to form a biodegradable surfactant having a saccharide structure. The composition of the saccharide derivative type surfactant and the amino acid type surfactant having a specific structure of the present invention is particularly suitable as a coloring fixing agent for a wool fiber material.

Conventional surfactants in the prior art mostly use petroleum as a raw material, and their decomposability is poor, and some may even contain toxicity, which is easy to pose a threat to the environment. In the dyeing of wool fiber materials, most of the surfactants derived from petrochemical products and chemically synthesized dyes have better coloring and fixing ability, but the surfactants from chemical products and chemically synthesized dyes are on the human body. Health and environmental damage is considerable. And because of the petroleum-based products, many are not easily decomposed naturally. A large amount of waste causes serious environmental pollution on the earth. In order to reduce this phenomenon, the treatment technology of pollutants, the engineering technology to reduce pollutants and the development of decomposable raw materials are highly valued.

It was born from the development of natural plant extracting dyes and green environmentally friendly surfactants, but it is taken from the plant extracting dyes, usually the dyeing color is not bright enough and the dyeing fastness is insufficient, the color is not rich enough, therefore, It is not completely possible to replace chemical synthetic dyes, so there are many restrictions on the application, so it is necessary to find a solution, and the application of environmentally friendly green surfactant as a fixing agent is an important key.

Amino acids are mostly used in organic synthesis, petrochemical, medical and other fields in research. Because its structure is the basic substance composed of the human body, it is a necessity for human growth, development and nutrition. The main application in biology is to help the pituitary gland to function normally, stimulate growth hormone and remove toxins from the body, and maintain DNA integrity. Amino acids are far superior to traditional chemicals in their mildness to the human body and their low environmental pollution. Therefore, based on the premise that human beings pay attention to green environmental protection, further research on amino acids and their derivatives is of great significance.

Amino acids are the basic units that make up a protein, which imparts a specific molecular structure to the protein, making the molecule biochemically active. Protein is an important active molecule in the body, including enzymes that catalyze metabolism. An organic compound having an amine group (-NH ₂ ) and a carboxyl group (-COOH) in an amino acid molecular structure, and both an amine group and a carboxyl group are directly bonded to a -CH- structure. The formula is H ₂ NCHRCOOH. The amino acid (C...CCCC-COOH) of α, β, γ, δ, ... can be classified according to the position at which an amine group is bonded to a carbon atom in a carboxylic acid. After hydrolysis of the protein, more than 20 alpha-amino acids are formed. Depending on the binding group, it may be classified into an aliphatic amino acid, an aromatic amino acid, a heterocyclic amino acid, a sulfur-containing amino acid, an iodine-containing acid or the like.

The basis of the amino acid as a surfactant can be traced back to 1909, and the hydrophobic group was first applied by glycine and alanine. Since then, amino acid type surfactants have had many research topics, and have great potential for application in the human market, such as medicine, cosmetics, food, and the like. The surfactant of the amino acid type is classified into an acidic amino acid, a basic amino acid or a neutral amino acid. Amino acid-based surfactants are synthesized as a starting material for the hydrolysis of proline, glycine, alanine, arginine, aspartic acid, leucine, serine, proline and protein. It is used in commercial and experimental research.

At present, amino acid surfactants are used in various environments under the rise of the green environment. area. In the achievements of cosmetics, it has been confirmed that the amino acid esters and sulfhydryl groups have excellent emulsifying properties and strong antibacterial properties, and are biodegradable surfactants which exhibit low toxicity and exhibit antibacterial activity. It is an important property of amino acids and their derivatives. Amino acid surfactants can be described as relatively high-temperature anionic surfactants. However, the use of traditional anionic surfactants in the world is gradually burdened by environmental burdens and high allergic irritations. Substituted by a nonionic surfactant. However, the amino acid-based anionic surfactants have a growth rate of 21% in 2003 due to their low environmental burden and low allergic irritancy, coupled with the better decontamination effect of anionic surfactants. Traditional anionic surfactants have been unable to stand. From this, it can be seen that the market for surfactants will be an amino acid type surfactant having environmentally friendly, low irritation, hypoallergenic irritant and potent decontamination effects.

Nowadays, amino acid surfactants are mostly obtained by reacting an amino acid with a long-chain fatty acid, and are usually formed by reacting with a fatty acid having 8 to 22 carbon atoms to have a structure having a hydrophilic-hydrophobic group. The present inventors have carefully studied that amino acid can also form an amino acid surfactant by reacting with a short-chain fatty acid, and unexpectedly found that these surfactants have an interface obtained by reacting an amino acid with a long-chain fatty acid in the prior art. The active agent has more excellent surfactant properties.

Polysaccharides are a very common chemical commonly used in large quantities. They are used in large quantities for the use of pharmaceutical foods. A small number of polysaccharides have been modified to be used as surfactants for emulsifier use in pharmaceutical foods. Most of the products sold in the market are composed of only a single hydrophobic and hydrophilic raw material, and the structure is simple, and the properties exhibited by them are limited, and the application range is not wide. Polysaccharide surfactant has good interfacial activity, biodegradability, low toxicity to humans and excellent Emulsifying properties. The use of polysaccharide surfactants can reduce the market utilization of petroleum-based surfactants. In general, industrial products require the emulsification or dispersion process of raw materials in the manufacturing process. Emulsifying dispersibility is an important interfacial activity of surfactants. The emulsifying and dispersing agent used must, in addition to the basic properties of emulsification and dispersion, be consistent with (1) non-toxic or low toxicity (2) biodegradability. Durand et al. reported that hydrophobically modified polysaccharide dextran is used as a polymer stabilizer for O/W emulsions to adjust the surface properties of porous or massive particles, making it suitable for microemulsification polymerization of polysaccharide nanoparticles. Morales et al. synthesized alkylated gallic acid glucose as an antioxidant function, the composition having superior interfacial activity and lower critical cell concentration values than the nonionic surfactants Brij-30 and Tween-20. Wu et al. investigated the microcyst properties of polysaccharide dextran/PLA copolymers. As the concentration of polymer increased, the fluorescence intensity increased, and the ratio of fluorescence intensity decreased with increasing concentration, indicating the formation of micelles. The water-based copolymer forms stable micelles in solution, so the copolymer has a lower critical cell concentration.

Under the trend of stable development in the world, surfactants provide an excellent environment for the development of related industries, and the structure, items, performance and technical requirements of products are also getting higher and higher. Therefore, the development of safe, mild, natural, biodegradable and special surfactants provides a good foundation for the development and application of new products. Future market trends will be toward the development of glycoside surfactants, a variety of polyols and alcohol surfactants, soy lecithin surfactants, sucrose fatty acid surfactants, and amino acid surfactants. Formulated technology to develop the range of applications for existing products.

Currently, glucose derivative surfactants and amino acid surfactants are in green The environment is used in various fields. In the achievements of cosmetics, it has been confirmed that glycosyl, amino acid esters and sulfhydryl groups have excellent emulsifying properties and strong antibacterial properties, and are biodegradable surfactants, which exhibit low toxicity and exhibit antibacterial properties. Activity, which is an important property of amino acids and their derivatives. The market for surfactants will be a glucose derivative surfactant and an amino acid type surfactant having environmentally friendly, low irritation, hypoallergenic irritant and potent decontamination effects.

Wool fiber has the existence of hydrophobic outer skin layer and dense scale layer, as well as the difference of wool itself. It is easy to cause uneven dyeing of wool and chromatic aberration of hairy root. To avoid uneven dyeing, we add our interface activity here. The agent increases its excellent dyeing effect.

Plant pigments are environmentally friendly and less harmful to the human body. However, plant pigment dyeing hair, fiber color and color fastness are often insufficient, and surfactants play an important role.

Agent. The N-mercapto-amino acid type surfactant is a green chemical product, but if the preparation time is too long in the production process, the product will be gradually eliminated by the society if the industrial "three wastes" are excessive. In recent years, with the concept of “green chemistry”, it is increasingly required that chemical products be produced from the source with a green concept.

△L*=L* sample-L* standard (lightness difference, + shallow) △a*=a* sample-a* standard (+ reddish, - greenish) △b*=b*sample-b* standard (+ yellowish, - bluish) One of the important indicators for dye dyeing performance evaluation is the depth of dyeing. The Kubelka-Munk staining depth equation establishes a certain functional relationship between the absorption coefficient K and the scattering coefficient S of the measured object and the concentration C of the colored substance in the solid sample. The larger the K/S value obtained by calculation, the deeper the surface color of the solid sample, that is, the higher the concentration of the colored substance, the better the dyeing performance of the dye. The color change (before and after the weathering test) is the ΔE (DE) value. DE is calculated according to the L, a and b values (reflected values) of the CIE system using the following equation: [(ΔL) ² + (Δa) ² + (Δb) ² ] ^1/2 = ΔE (DE). The following sample K/S values were calculated from the instrument, where K = absorption, S = scattering, R = reflection in the case of minimal reflection: K / S = (1-R) ² /2R in the sample instrument, The K/S value is measured at the minimum reflection wavelength. The instrument conditions are: CIE lab, D65 source, 10 degree observation angle, including spectral composition (SCI), small area observation (SAV), scanning wavelength = 400-700 nm. The higher the K/S value, the deeper the chromaticity.
