Definitions

  • the invention encompasses cosmetic or dermatological preparations comprising a combination of polyacrylate and polyacrylamide thickener. Despite a high proportion of skin moisturizing agent, the preparations have advantageous stability and product sensor technology.
  • Skin moisture is a term from the cosmetics industry. Healthy skin has a natural moisture. Only when the human skin shows anomalies with regard to dryness, does the lack of skin moisture come into play. Apart from pathological causes, the age of the human skin and the pigmentation also play a role. An important role in the hydration of the skin is played by moisturizing factors, e.g. Urea. These can be supplied to the skin by skin care products.
  • moisturizing factors e.g. Urea.
  • humidifiers can be used to support a healthy skin moisture.
  • Moisturizers also referred to as moisturizers, are substances or mixtures of substances which impart the property to cosmetic or dermatological preparations after application or spreading on the surface of the skin

  • a disadvantage has hitherto been that a high proportion of humectants in emulsions meant that the care emulsions had an unacceptable consistency and a non-desired by the user stickiness. It is desirable to provide preparations which can be provided at high skin moisturizer content, in particular a high polyol / glycol content, in particular glycerol content, without any loss of product sensor technology.
  • Thickeners are auxiliaries for establishing a suitable product consistency and a suitable flow behavior of cosmetic or dermatological preparations. They are preferably used in emulsions and surfactant-containing cleaning products.
