Definitions

  • oils and waxes require the addition of solubilizers or solubilizers in order to be processed homogeneously and stably. Products without solubilizers are biphasic and must be shaken before use, which is not always popular.
  • the incorporated oils can adversely affect the foaming of the surfactants in quality or significantly reduce the amount of foam formed when using the detergent. Since the consumer usually equates the amount of foam formed with the cleaning performance of the agent, at least a good foaming power for cosmetic products with oil shares is still desired.
  • WO 2008/155075 describes cosmetic preparations which, in addition to non-alkoxylated surfactants, contain a microemulsion comprising alkylpolyglycoside, glycerol monoester, an oil body and water. These cosmetic preparations are useful as hair shampoos with conditioning effects because they enhance the deposition of silicone oils and introduce relatively high levels of softness and moisture having oils into hair shampoos.
