  • Cleaning products are designed to clean the skin and hair. After the cleaning process, the user ideally has a feeling of cleanliness, freshness and well-being. Humans have always had the need to cleanse themselves. H. Remove dirt from the skin or hair. Over time, the cleaning processes have changed, as have the products that are used for cleaning.
  • the skin is cleaned, for example, by washing, shower baths or bath tubs, while the hair is often also cleaned during the shower bath or bath tub or also washed separately.
  • Body cleansing products primarily serve to remove dirt from the skin surface.
  • the dirt film consists of solid or liquid components that have reached the skin from the outside. Excess skin lipids and dead body cells also belong to the dirt film. The components of the dirt film get into the wash liquor through surface-active ingredients in the cleaning compositions and are removed from the skin by the rinsing process.
  • the products should be easy to distribute in the hair, the foam should form quickly, the hair should be cleaned and cared for gently and gently. In addition, it should be easy to wash out and wet hair should have a pleasant feel and be easy to comb. Dry hair should also be easy to comb, the appearance of the hair should be natural and it should shine. The products are said to make the hair supple and not to weigh it down. In addition, rapid relubrication should be prevented. So there is a long catalog of requirements in the area of hair cleaning, which at least to a large extent has to be fulfilled in order to be able to sell a product that is accepted by the consumer.
  • a cleaning preparation also plays an important role in the acceptance of a product by the consumer. Cleaning preparations in a white color are very attractive for the customer. The white color associates purity and cleanliness. If a white cleaning preparation also has a creamy consistency, the customer also associates good care with this product.
  • Opaque or "white” cleaning compositions are known per se. To give cleaning compositions this appearance, opacifiers or pearlescent agents are generally used. Pearlescent agents can be heavy metal salts of higher fatty acids, fatty acid esters or fatty acid diesters of polyols or fatty acid alkanolamide derivatives. These substances exist as crystal platelets or rods and reflect the light. Opacifiers have no pearlescent effect per se.
