The hydrated aluminum compounds according to the present invention are represented by the general formula n S, m M Al2 O3, x H2 O in which S is a surfactant or a group of surfactants, n being the number of moles of S, M is an alkaline cation, preferably M is chosen from the group formed by Na +, K +, NH4 +, m being the number of moles of M and x is the number of moles of water. The hydrated compounds are obtained from inorganic sources of aluminum which are in the form of cation-monomers and / or cation-oligomers. The surfactants used are anionic and / or nonionic surfactants. In the case where the group of surfactants comprises at least one anionic surfactant, it is optionally possible to add at least one cationic surfactant. |
