Phosphate esters and sulfonate silicone surfactants are the most common. ANTHONY and others use toluene as the solvent. Alkenyl polyether compounds react with hydrogen-containing silicone oil under th......
2020-02-10When the hydrophilic group contains structural units such as sulfonate, carboxylate, phosphate, and sulfate, it is an anionic silicone surfactant. Generally, polyether-type silicone oil is used for ca......
2020-02-10Other scientists have found that the larger the proportion of hydrophobic polysiloxane in the polysiloxane quaternary ammonium salt molecules, the longer the molecular chain, the better the wet combab......
2020-02-10Chinese scientists synthesized cationic polyether-modified silicone quaternary ammonium shampoo conditioners through addition, ring-opening, and quaternization reactions. The mass fraction of unreacte......
2020-02-10When the hydrophilic group contains quaternary ammonium salt, imidazole salt, pyrrole salt, pyridine salt and other structural units, it is a cationic silicone surfactant, especially the quaternized p......
2020-02-10According to the connection mode between the polyether segment and the siloxane segment, it is further divided into: Si-O-C type and Si-C type. Si-O-C type polyether modified polysiloxane is mostly ob......
2020-02-09Non-ionic surfactants are mainly silicone-polyether copolymers composed of a polysiloxane backbone as a hydrophobic group and a polyether as a hydrophilic group. By changing the type, quantity and pos......
2020-02-09Silicone surfactants are a new generation of surfactants that have been researched along with the rise of new silicone materials in recent years. The surface activity of the hydrophobic siloxane chain......
2020-02-09Another innocent victim in the large industrial field said that it was not natural but did not blame him. There is indeed no such thing as "semi-organic matter" in the natural world. Early application......
2020-02-09As a kind of petroleum derivative, it is often "unnatural". Isn't petroleum a natural product? Not to mention the rumors of "boggling acne" that has been circulating for many years, so far there is no......
2020-02-09Resveratrol is a special case. Many people believe that the "French Paradox" arises from it. French people love to eat greasy foods, but they have less cardiovascular disease than Americans. One theor......
2020-02-08It may not be as big as medicine, but the ingredients from food and health food can also bring a clear stream to the industry. Excessive reactive oxygen species and free radicals are healthy ......
2020-02-08The birth of a good product does not rely on simple stacking of active ingredients. Formulation technology is the key. Stability of the active ingredients, compatibility with each other, and full cond......
2020-02-08There are countless examples of inadvertent insertions in the medical world. The most famous one is sildenafil, which is designed for cardiovascular treatment, and finally became a famous Viagra. A si......
2020-02-08It is also a great god who introduced these two substances into cosmetics: Dr. Sheldon R. Pinnell (RIP), co-founder of Xiuli Ke, and the first chief scientist, Duke University ’s chemistry major turne......
