General Detergent formula design principles are as follows:
Improve product applicability by optimizing recipes: For example, our country is accustomed to low temperature or room temperature washing, the proportion of chemical fiber in textiles is larger, the region is broad, the hardness of water quality difference; Due to the differences in living habits, clothing, the different types of dirt and other reasons, so the formula designer must carefully study the product by series fine Division
Iii. giving new features
Products in the improvement of applicability at the same time, but also to give products new functions, so as to meet the requirements of different levels of consumers.
Iv. Choice of Lotion
Reasonable selection of various help lotion, can effectively improve the product decontamination force, and significantly reduce the amount of surfactant.
V. Use of enzyme preparations
Adding enzymes can improve the ability of liquid detergent to remove the dirt of fat and protein.
Common detergent composition is divided into surfactants, additives and so on.
Liquid detergent is mainly nonionic surfactant, supplemented by anionic surfactants. Nonionic surfactants mainly use fatty alcohol polyoxyethylene ether and alkyl phenol polyoxyethylene ether, and the commonly used varieties are AEO-9 and TX-10.
A. Alkaline auxiliaries: Alkaline auxiliaries used in detergent are mainly carbonate, phosphate and silicate, most of which are sodium salts or potassium salt and triethanolamine. Adding solvent is added to increase the solubility of the material in water.
B. Solvent: common solvents are sodium toluene sulfonate, sodium P-toluenesulfonate and Isopropyl benzene sulfonate, low molecular weight phosphate ester, sulfonic acid salt and uric acid, etc.
Anionic and nonionic surfactants can form mixed micelles in solution, and can also provide solubilization of third substances.
C. Solvents: Commonly used solvents are ethanol, ethylene glycol, propylene glycol, ethyl ether, diethylene glycol ethyl ether, ethylene glycol butyltin ether, propylene glycol methyl ether and propylene glycol methyl ether, etc.: the latter ether class with hydroxyl and ether, the existence of two groups, so that they have a strong ability to dissolve oil, but also a good coupling.
D. Viscosity regulator: carboxymethyl cellulose sodium in the washing powder has the effect of anti-fouling and thickening of the product. In order to prepare transparent liquid products, polyethylene pyrrolidone (PVP) can be added.
Ethanol, isopropyl alcohol and other solvents have reduced the role of product viscosity, potassium chloride and sodium chloride used to adjust the viscosity of the product, especially the product contains fatty alcohol polyoxyethylene ether sulfate, the addition of sodium chloride has a significant thickening effect, but the amount of excess, but also to reduce the viscosity of the role.
E. chelating agents: Often organic chelating agents, such as EDA, sub-amino acid sodium and sodium citrate. such as phosphate, potassium triphosphate or potassium pyrophosphate, etc. Using ethyl two amine acetic acid triethanolamine ester and ethyl two amine acetic acid triethanolamine disodium salt to replace the sodium tripolyphosphate can not only guarantee the transparency of products, but also improve the ability of integrating calcium and magnesium ions.
F. Enzyme preparation: Protease and amylase are two kinds of enzymes applied to liquid detergent.
