Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl and many other ingredients betaine in water. The goal of using shampoo is to remove the unwanted build-up in the hair without stripping out so much sebum as to make hair unmanageable. Basic shampoos simply clean the hair, there are products designed for specific hair types; products which offer properties such as treatment of dandruff; UV protection and “medicated” products etc. Thus, formulations vary widely; however, the range of ingredients used can be summarized as water, surfactants, conditioners, viscosity modifiers, ph adjusters, preservative, coloring and fragrance. Usually a typical manufacturing process would be as follows. Firstly, heat water in the vessel to 55-60˚C. Secondly, add ingredients such as surfactant, conditioners and other additives, particularly those which affect viscosity, can make dilution of the surfactant more difficult. Last, adjust PH and add sodium chloride or other viscosity modifiers, along with color and fragrance.
Generally speaking, using a conventional agitator can mix all the ingredients needed in the shampoo manufacturing, but it takes a long time to mix. Furthermore, many problems can be encountered. Following are several main problems. Some ingredients such as silicones are immiscible with water and chemically incompatible with some surfactants which make it very difficult to emulsify or suspend; many ingredients have a much higher viscosity than water. When blending these with an agitator, the higher viscosity material can form globules which are simply washed around without being dispersed; aeration can be easily formed. In a word, using a conventional agitator can be very hard to obtain a stable emulsion.
Under this circumstance, manufactures that make shampoos can use a KOS high shear mixer to overcome problems encountered by using an agitator. Because the powerful suction created by a KOS high shear mixer draws the materials through the pipeline into the stator or rotor work head. And centrifugal force drives the materials to the periphery of the work head where they are subjected to intense high shear in the gap between the rotor and stator. After thousands of times circulation of above actions, a KOS high shear emulsifier can easily help to obtain stable and better emulsion. What’s more, a high shear homogenizer can rapidly blend liquids of widely differing viscosities, which can reduce mixing process time. The most important thing is that consistent product quality and repeatability can be achieved. High shear homogenizer is just one of the emulsifying machines in Kos. We also have bottom homogenizer machine, emulsify tank, emulsifying pump and many other industrial emulsifying machines. Come to visit our website: http://www.emulsifyingmixer.com
