Application of Alkyl Glycoside APG in Daily Chemical Products2020-10-13 13:19
Alkyl polyglycoside refers to the alkyl furoside (Alkyl Polyglycoside. referred to as APG) synthesized with glucose and fatty alcohol. It refers to the glycosides with sugar units greater than or equal to 2 in the complex glycoside compound, collectively referred to as alkyl polyglycoside (or alkyl polyglycoside) ). In general, the polymerization degree n of the alkyl polyglycoside is in the range of 1.1 to 3, and R is a C8 to C16 alkyl group. APG is a white solid powder or light yellow oily liquid at room temperature. It has high solubility in water and is difficult to dissolve in common organic solvents. The following describes the application of the alkyl glycoside APG in daily chemical products.
a. Industrial cleaning agent
Alkyl glycoside APG still has good solubility and compatibility in concentrated strong acids, strong bases and electrolytes, and can be used to prepare industrial cleaning agents. It is used to clean the soil and oil on the surface of automobiles, machinery, drilling, etc., and has the function of delaying metal oxidation and corrosion. Compared with alcohol ethers, alkyl glycosides have good compatibility with plastic products; cleaning plastics such as acrylic glass, ABD and polycarbonate with alcohol ether-containing cleaning agents will quickly cause stress cracking or even fracture. The alkyl glycosides will not cause plastic cracking, and the cleaning effect is very good. Therefore, alkyl glycosides are ideal raw materials for hard surface cleaners. After compounding alkyl glycosides and alcohol ethers, the addition of alkyl glycosides not only improves the compatibility of alcohol ethers with plastics, but also has excellent cleaning performance. When the total active matter is the same, the cleaning performance of products containing alkyl glycosides is significantly higher than that of cleaning agents without alkyl glycosides. Adding alkyl glycosides can reduce the total active matter of the cleaning agent while maintaining the cleaning power. And cost is conducive to market competition.
b. Dishware cleaner
With the continuous improvement of people's living standards, dishwashing detergent has become an important product of household cleaning products. The requirements for dishwashing detergents have also changed from the original simple high foam, good foam stability in the presence of greasy dirt, excellent emulsification ability and number of dishes to the consideration of the above requirements. The skin irritation and toxicity of dishwashing detergents are also considered. The low toxicity and irritation of alkyl glycosides make it an ideal raw material for the preparation of dishwashing detergents. Due to the non-rinsing and spot-free characteristics of alkyl glycosides, when used in dishwashing detergents, bottle washing agents, etc., it has strong degreasing ability and has a refreshing and comfortable feeling of use.
c. Laundry detergent
In the series of alkyl glycosides APG, alkyl glycosides are particularly effective in removing oily dirt as a nonionic surfactant. Alkyl glycosides have the following advantages when used in laundry detergents: ① It can produce rich and delicate foam. Due to the existence of these fine foams, the friction of clothes, especially fine clothes, such as wool and silk products, in the washing machine is reduced, which is beneficial to fabric protection. ②Suitable for cold water washing. ③Reduce the irritation of laundry detergent. Laundry detergents equipped with alkyl glycosides can effectively remove soil and greasy dirt, and have softness, antistatic properties and shrinkage resistance, and can be used normally in hard water.
The use of alkyl glycosides can be made into a non-toxic nutrient shampoo, no harm to human body and hair, no irritation, can nourish the hair, nourish the hair, and make it long-lasting moisturizing, prevent the hair from drying and splitting; the hair is smooth and smooth , Easy to comb, antistatic. Alkyl glycosides have rich foam, suitable viscosity, good detergency, moderate pH, and meet national standards.
e. Toilet cleaner
The toilet cleaner composed of alkyl glycoside APG can effectively protect the rubber and plastic parts of the toilet. Moreover, because alkyl glycosides have broad-spectrum antibacterial activity, C8-12APG has antibacterial activity against gram-negative bacteria, gram-positive bacteria and fungi, so it is more advantageous as a sanitary cleaning agent. The toilet cleaner mainly removes feces, scale and dust deposits and urine scale. The original formula is made of strong acids such as hydrochloric acid and phosphoric acid with surfactants, but these strong acids can cause skin injuries when they are used accidentally. The current trend is to replace strong inorganic acids with biodegradable organic acids. It is combined with an acidic acid-stable alkyl glycoside to form a toilet cleaner, because the addition of alkyl glycoside is beneficial to the removal of scale and organic dirt.
f. Skin cleansing agent
As mentioned earlier. Alkyl glycosides are almost non-irritating to human skin. Therefore, alkyl glycosides are completely suitable for skin cleansing baths and facial cleansers. At the same time, the phase behavior of alkyl glycosides also makes it easy to compound with other surfactants to form products.
As a new type of nonionic surfactant, alkyl glycoside APG has many unique advantages. Such as: obvious synergistic effect with anionic surfactants; rich foam; low skin irritation; non-toxic and good biodegradability, etc., which make alkyl glycosides have a certain degree in the formulation and application of daily chemical products Superiority, so as to obtain a wide range of applications.
