aerated soap bar, process of preparing aerated soap bars and use. the present invention relates to aerated bars of soap. in general, it is difficult to obtain aerated soap bars with the correct level of aeration, since the high viscosity of the molten soap mass sometimes makes it difficult to aerate to the desired point. the size and movement of air bubbles also play important roles. bars with large air bubbles have a lower mechanical resistance. it was determined that the use of acrylates or cellulose ethers in aerated soap bars leads to bars with an acceptable rate of wear, porridge (mush) and lower density. soaps also have a higher and more uniform air incorporation and better air retention. the present invention also relates to aerated soap bars having a density from 0.2 to 0.99 g / cm3, which comprise: (i) 20 to 80% by weight of soap; (ii) from 2 to 40% by weight of polyol; (iii) from 5 to 50% water, and, (iv) from 0.5 to 5% by weight of electrolyte; wherein the bars comprise 0.1 to 5% by weight of polymer selected from acrylates or cellulose ethers. |
