In the cosmetic industry, it can be a challenge for manufacturers to produce the correct formulations of high volumes of powders. The challenge is compounding the powders that include the processing of such ingredients as Carbopol, HPMC, polymers, and xantham gum (highly viscous thickeners, highly hydrophilic), that are difficult to disperse without 'fisheyes.' The production technology and the energy provided in the mixing impacts the final results regarding stability, consistency, and colour. The most efficient powder dispersers will effectively create a homogenous mixture in a single pass.
Conventional in-tank dispersion and emulsifying methods do not produce the desired results all of the time. Powders and immiscible liquids introduced into a vessel of liquid must find their way to the mixing impeller to be effectively sheared and dispersed. Only a portion of the material introduced will reach the tooling for processing. The result is random rates of shear leading to over processing. The inadequate dispersion leads to waste and results in the production of "fish eye" lumps. As well, the introduction of unwanted air into the batch mix affects the results making consistency unachievable. Trying to resolve the problem by using higher horsepower mixers will only damage shear and heat sensitive products.
When it comes to formulations and processing in the cosmetic industry, single-pass mixers, dispersers, and emulsifiers resolves the problems associated with conventional in-tank dispersions and emulsifying methods. The unique single pass technology creates high-quality dispersions and emulsions and maximizes yields by applying the required shear to all the material in a very fast single pass. In addition, it comes with a broad range of tooling that can be specifically tailored to a specific application.
Whether you produce make-up powders, cosmetic liquid foundations, lipsticks, creams and lotions, shampoos, and more, a single-pass process can achieve the size reduction/dispersion requirement. A single-pass process delivers high product quality that is not only repeatable, predictable, and scalable, it can greatly reduce batch times and energy consumption by as much as 75%. In addition, wasted powder, air entrainment, and batch-to-batch cross contamination are eliminated. A single device can even process multiple applications feeding several batch tanks.
The single pass technology has proven to be effective for the dilution of high active surfacants and the high speed dispersion of Bentonite Clay. When the Bentonite Clay has been introduced and blended, a single pass of the solution through the high shear, fine radial tolerance Z Emulsifier will achieve the maximum viscosity building properties of the Bentonite Clay. The single pass technology can even produce lump free dispersion of carbomers and polymers. Carbomers and Polymers have been used as rheology modifiers or structure building agents in a broad range of applications including Pharmaceutical, Personal Care, Industrial products, and Home Care, because of their excellent stabilizing, thickening, and suspending properties.
