Hair conditioners are applied after hair washing and are characterised, in contrast to shampoos, by a low pH-value (pH-value is in the “acidic” range). The composition of the ingredients can vary widely from product to product. However, most hair conditioners contain proteins, acidity regulators, moisturisers and preservatives, oils, tensides, perfume, static inhibitors and lubricants. The hair rinses achieve a closure of the dandruff layer, which is opened after washing, and are intended to smooth the hair surface and make it easier to comb.
In order to achieve the best possible integration of the ingredients, the production of hair conditioners makes complex demands on the production plants and processes. High-performance process plants can seamlessly carry out complicated production steps. They take over the suction and mixing of water and fat phases both in the hot process and at room temperature in the context of a cold production.
In addition, complex plants enable the dissolving, melting and mixing or emulsification of all raw materials immediately prior to their addition to the basic substance. The homogenization mixers should also be able to process highly viscous components without any problem. The possibility of pH-value control in a process can further reduce the batch time. A Cleaning-In-Place (CIP) system under the lid should guarantee compliance with the strict hygiene regulations throughout the entire production process.
