In the production of shower gels, starting materials of varying consistencies/features are combined to give a stable, effective starting substance in the course of production. The basis of most shower gels is an oil-water mixture which is distributed stably by means of emulsifiers, such as lecithin, fatty alcohols, lactic acid esters or glyceryl laurate. In the case of high water content, thickening agents, gelling agents and additional auxiliary substances, such as xanthan, cellulose, alginate and polyglycerol ester, are also added in order to produce a pleasantly viscose basis. Tensides are added to the shower gels and give them their cleaning effect. An important factor here is regulation of the pH-value in the range around 5.5.
The production of shower gels requires a highly efficient, multi-stage process. The homogenising mixers/process plants employed should be extensively equipped and possess a wide range of equipment options for optimum processes in the production of shower gels. By suction of water and powder under fluid level in the area of the dispersion tool, the powder is incorporated quickly and without clumping.
Vacuum-proof machine design prevents the undesirable incorporation of air. A scraper system that is independent of the rotation direction, in combination with vertical and horizontal mixing agitators, achieves optimum mixing in the case of highly viscous substances. In some cases it may be useful if there is the option of installing a pH-value monitoring device in the homogenisation chamber.
Aseptic GMP design of the plants, an integrated CIP-System under the lid and the homogenising mixer also ensure efficient product processes and compliance with all hygiene regulations during the production of shower gels.
