Definitions

  • New surfactant mixture novel composition comprising and use in cosmetics
  • the present invention relates to a novel process for improving the foaming properties of topical formulations, novel compositions for topical use, their use for cleaning skin, hair, scalp, mucous membranes, and a method of cleaning the skin human and animal, hair, scalp and mucous membranes.
  • the present invention finds application in the cosmetic and dermocosmetic, dermopharmaceutical and pharmaceutical human and veterinary field.
  • Cleaning formulations include cleansing and foaming surfactants, whether of cationic, anionic, amphoteric or nonionic nature. These surfactants are said to be amphiphilic because they consist of a hydrophilic part (or polar head), soluble in water, and a lipophilic part (hydrophobic tail) which has an affinity with oils and greases. This amphiphilic structure makes it possible both to dissolve greasy soils and to eliminate them by a washing operation.
  • Anionic surfactants have historically been surfactants which have been used to prepare foaming cleansing formulations for topical use.
  • Sulphated anionic surfactants are a class of surfactants frequently used because of their good foaming properties. These surfactants are known for their good cleaning power, and they also produce an aerated foam whose feel is not considered unpleasant by the consumer.
  • these surfactants have the disadvantage of being sensitive to the degree of hardness of the water and the presence of greasy soils, which consequently leads to a decrease in the volume of foam initially generated by these formulations but especially a decrease in the stability over time of this volume of foam.
  • fatty acids as foam stabilizing agents, whose aliphatic fatty chain comprises from 8 to 30 carbon atoms, in mass proportions greater than or equal to 10% by weight for 100% of the mass of said cleaning formulation for topical use.

  • the French patent application published under the number 2,850,017 discloses a means for stabilizing cosmetic compositions in the form of foams by using fatty acids in small amounts, provided that this foam is obtained from a emulsion in the form of oil-in-water and to associate said fatty acids with sugar derivatives, and more particularly alkyl glycosides, said combination being described as "emulsifying".
  • the fatty acids used in the French patent application published under number 2,850,017 are carboxylic fatty acids with a linear or branched aliphatic chain containing from 6 to 22 carbon atoms.

TM 82 (INCI name: cetearyl alcohol and coco-glucoside), MONTANOV TM L (INCI name: C14-22 alcohol and C12-20 alkyl glucoside).
  • Foams generated by aqueous solutions comprising such N-acyl derivatives of glutamic acid, or a salt thereof, and / or aspartic acid, or a salt thereof, have both advantage of forming with an average expansion time and to show mechanical properties making them suitable for use in a step of removing cuttings during a drilling operation of underground cavities.
