For manufacturers of cooking oils, an authoritative, scientific, fair and accurate testing report on their oil products can help their organization win better reputation for delivering quality and value. For individual clients, a testing report is helpful to reassure them about the safety of the oils. Usually, a comprehensive cooking oil testing project should cover the following parameters: Nutrient content testing , which covers: flavor quality, product quality grade, fat...

Emerged as a supplier of quaternary ammonium compounds (QACs), Alfa Chemistry has previously released halide quaternary ammonium salt and acid radical quaternary ammonium salts, and aimed to further enrich its portfolio, the company recently introduces a new polyquaternium product line for customers who are engaged in the cosmetics and personal care products industry. Polyquaternium is a neologism used to emphasize the presence of quaternary ammonium centers in the polymer. Being positively charged, polyquaterniums are capable to neutralize the negative charges of most shampoos and hair proteins and help hair lie flat. As a result, polyquaterniums have found particular application in a wide range of hair products such as conditioners, shampoo, hair mousse, hair spray, and hair dye as well as other personal care products such as personal lubricant and contact lens solutions. International Nomenclature for Cosmetic Ingredients (INCI) has approved at least 40 different polymers under...

The boom of semiconductor device fabrication industry spurs an increasing demand for semiconducting materials. To make such raw materials more easily obtainable, the US-based chemical supplier Alfa Chemistry recently announces to release varieties of materials that could be used for lithography , a very important step in the manufacturing of IC manufacturing. The manufacture of semiconductor devices involves a sequence of many photolithographic and chemical processing steps, for instance, surface passivation, thermal oxidation, planar diffusion and junction isolation. During this process, electronic circuits are gradually created on a wafer made of pure semiconducting material. Different semiconductor materials are used for different application purposes. “In general, a typical photolithography process would cover steps like substrate preparation, photoresist spin coating, pre-baking, exposure, post-exposure baking, development and post-baking,” says the Marketing Chief of Alfa Che...

Polymer stabilizers are essential substances in industrial production and human life. Reputed as a reliable supplier of varieties of materials and chemicals, Alfa Chemistry decided to add a brand-new product line of polymer stabilizers. To this end, a sub-website is built to be solely devoted to the offering of all kinds of high-quality polymer stabilizers and related custom synthesis services. As its name suggests, polymer stabilizers are added to prevent the degradation of polymers during processing or use, thus prolonging their life. “Leveraging years of experience and strong expertise, we are committed to the manufacturing and development of innovative polymer stabilizers for the most demanding applications,” says the Marketing Chief of Alfa Chemistry. At present, a comprehensive range of stabilizers are available at Alfa Chemistry, ready to serve as additives for plastics, which are listed below: Antioxidant Antioxidants can inhibit autoxidation that occurs when polymers ...

Ever since the launch of a wide range of glycerides in the first quarter of last year, there are increasing in-coming demands for glycerides from clients across the globe. To improve user experience, Alfa Chemistry announces to upgrade and optimize this product line by further diversifying the supply of different types of glycerides , including monoglycerides, diglycerides, triglycerides. All these high quality glycerides are fast-delivered and can be used to support many research projects in multiple fields. Customers can choose saturated and unsaturated types based on their research requirements. Monoglycerides Composed of a molecule of glycerol linked to a fatty acid via an ester bond, monoglycerides are found naturally in almost all foods in very small amounts. Diglycerides Consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages, diglycerides can act as surfactants and are commonly used as emulsifiers in processed foods, and the...

Carbon fiber materials, being extremely stiff, strong, and light, are increasingly used in many processes to create excellent composite building materials. To ensure the quality and integrity of such materials, Alfa Chemistry’s testing branch - T,C&A Lab, has recently announced to provide carbon fiber testing service for customers worldwide. Experts from Alfa Chemistry will offer insights on a series of tests carried out to characterize carbon fiber performance. Carbon fibers are very popular in many industries such as aerospace, automotive, military, and recreational applications. Serving as structural components in machines, vehicles, airplanes, or building components, carbon fibers must be tested to ensure safety. T,C&A Lab can test various types of carbon fibers and provide test results to help manufacturers and developers make decisions on the selection and design of composite materials as well as manufacturing processes. “The testing scope ranges from carbon fiber c...

Microfluidics is a very helpful tool in the biological sciences to conduct precise and controlled experiments at a faster pace and with lower cost. Alfa Chemistry recently announces to offer a wide range of microfluidic devices , including glass chips, microfluidic polymer chips, and many other functional chips.

Surfactants have become a flexible and diverse class of fine chemical products due to their physical and chemical effects such as wetting or anti-sticking, emulsification or demulsification, foaming or defoaming, solubilization, dispersion, washing, anti-corrosion, etc . Currently, surfactants are most widely used as detergents in daily life, but they have been found potentially useful in many other fields. Characteristics of Surfactant Solubilization Surfactants can increase the solubility of poorly soluble drugs in the dispersion medium, because surfactants can form micelles, and surfactants are amphiphilic, if the polarity of the drug is small and the polarity of the dispersion medium is large, the solubility of the drug in the dispersion medium will become smaller according to the principle of similar compatibility. At this time, if we add a surfactant, the surfactant can form an association, and the side with the larger polarity is in contact with the dispersion medium. The...
