Definitions

• the present invention relates generally to aqueous cosmetic compositions, in particular for the treatment of hair, comprising organic silicon compounds soluble in water, little or not at all polymerized.
• organic compounds such as polymers to produce cosmetic compositions for the treatment of hair.
• polymers used to dry solid materials are used to fix the hairstyle in a form. Such materials are also used to give shape retention effects.
• Polymeric compounds, such as polysiloxanes are also used to give care effects to hair, particularly damaged or difficult to disentangle hair.
• the cosmetic compositions containing these polymers are deposited on the hair which is left to dry or which is rinsed before going on to drying.
• the use of polymeric compounds has several drawbacks.
• the first drawback lies in the fact that, when the polymers are used in compositions above a certain concentration, the compositions obtained are difficult to apply due to the increase in the viscosity of the composition. This difficulty in applying the compositions leads to overloads in certain places of the hair and therefore to cosmetic defects and also implies that certain parts of the hair receive fewer compositions, which, in the end, induces a lesser effect on these parts.
• the second drawback lies in the fact that these compositions are sometimes difficult to implement. Indeed, the polymeric compounds with low solubility in water, require the use of organic solvent or mixture of organic solvents. The use of organic solvent causes several problems, such as environmental problems and effects on the cosmeticity of the hair.
