摘要 |
<p>A low-viscosity concentrated aqueous solution is described, which comprises from 25% to 60% by weight of one or more amphoteric surfactants, preferably alky! amido propyl betaines, and from 0,01% to 5% by weight of urea and/or sodium phosphate. The concentrated aqueous solution of the invention is characterized by a low viscosity, preferably lower than or equal to 3000 cps, as measured with a model LV Brookfield viscosimeter at 20°C, 20 r.p.m., and spindle 3. Methods of preparing the concentrated aqueous solution of the invention are also described.</p> |
