Definitions

  • cosmetics In addition to cleaning and caring for the skin, cosmetics also have an aesthetic task.
  • Cosmetics thus fulfill a psychological-social function, since they increase the (visual) attractiveness of the users.
  • Cosmetic preparations are usually differentiated according to their field of application (e.g. hair shampoo, face cream) and / or their structure (e.g. aqueous preparation, emulsion etc.).
  • the facial skin is particularly sensitive on the one hand and on the other hand to a particularly high degree
  • Day care products are usually characterized by the fact that they contain one or more UV filters to protect against UV radiation.
  • Night care products do not require UV filters. They are usually characterized by a significantly higher content of cosmetic active ingredients and a higher lipid content. For day care products, protection from environmental influences is more important, while night care products are intended to support skin regeneration and repair processes.
  • Hydrodispersions in the field of cosmetics are, within the scope of this disclosure, finely dispersed oil-in-water systems which, in contrast to the O / W emulsions, are not stabilized by surface-active emulsifiers, but by a polymer structure in the water phase , which prevents the "droplets" from flowing together.

  • alcohols e.g. fatty alcohols
  • emulsifiers are not considered emulsifiers.
  • Hydrodispersions are particularly suitable for sensitive skin types, for example with intolerance to emulsifiers.
