  • the soap composition according to the invention contains from 2 to 50% by weight relative to the total weight of the isoprene glycol composition.

  • the soap composition according to the invention will contain from 5 to 30% of isoprene glycol and better still from 8 to 25% by weight.
  • composition of the present invention can also, optionally, contain anionic, amphoteric, nonionic or cationic surfactants in order to improve the foaming power of the soap.

  • amphoteric or zwitterionic surfactants are the derivatives of aliphatic secondary or tertiary amines, in which the aliphatic radical is a linear or branched chain containing 8 to 18 carbon atoms and which contains at least one anionic water-solubilizing group carboxylate, sulfonate , sulfate, phosphate or phosphonate; alkyl (C8-C20) betaines, sulfobetaines, alkyl (C8-C20) amidoalkyl (C1-C6) betaines or alkyl (C8-C20) amidoalkyl (C1-C6) sulfobetaines.
  • the cationic surfactants are chosen from quaternary ammonium salts such as alkyl halides (C8-C22) trimethyl ammonium, dialkyl (C8-C22) dimethyl ammonium halides, alkyl halides (C8- C22) dimethyl hydroxyethyl ammonium.
  • 1,2-Ccan-C18 alkanediols as described in application EP-A-0 336803 to improve the foaming properties of soap.

  • the compositions in accordance with the invention may also contain active ingredients for the treatment of the skin such as anti-acne agents, anti-bacterial agents; they can also contain dyes, perfumes and other adjuvants usually used in cosmetics.
  • Solid, transparent soaps are prepared according to the invention in a conventional manner, by heating the fatty acids and the fatty substances to 75-80 ° C. to melt them and obtain a homogeneous medium. We then add isoprene glycol and optionally the other ingredients such as transparency agents, 1,2-alkanediols, surfactants, and other adjuvants. Then added, with stirring, the soda dissolved in water; stirring is continued for approximately 30 minutes. The soaps are poured in the form of breads at a temperature of 80-85 ° C., then allowed to cool to obtain the solid, transparent soaps, in the form of breads according to the invention.

The needle is blocked in this position. Using a micrometric adjustment wheel, the head position is finely adjusted in height in order to bring the point of the needle just in contact with the surface of the soap.
