  • the substitution of part of the water with glycerol provides some benefits on the conditioning of the hair, in terms of antistatic action and reduction of the frizz effect; however, a great deterioration in the amount and volume of the foam and in the spreadability of the product (Fig. 1A and IB), an important parameter for the end user, was observed. Furthermore, a worsening of the consistency of the product was observed: the substitution of part of the water with glycerol causes a reduction in the viscosity, which makes the product excessively fluid, therefore not usable by the operator and difficult to spread.
  • the formulas according to the invention in which water is completely eliminated in favour of glycerol as moistening agent, show a conditioning capacity equal to or even better than the formulas comprising water (F1-F3), an improvement of the post-drying parameters and even more surprisingly an improved cleansing capacity (see Figures 1C, ID and IE) .
  • the formulas according to the invention F4-F6 further provide equal amounts and volume of foam with respect to conventional formulas with water or even greater ( Figures 1A and IB) . Even more surprisingly, it can be observed that the substitution of water with glycerol allows to greatly reduce the concentration of primary surfactant agent while maintaining the cleansing capacity intact (see Fig. 1C) .
  • the reduction of primary surfactant is advantageous both in terms of costs and in that it favours an excellent tolerability of the finished product, also by persons with delicate, sensitive skin or with problems, such as skin allergies, dry and brittle hair, dandruff and dermatitis (Fig. IE) .
  • a water-soluble vesicle containing the composition of the invention after being exposed to water by the user, for example while washing hands or showering, may release the cleansing content thereof.
