FIELD: chemistry. ^ SUBSTANCE: claimed invention relates to multi-phase bars for personal washing, which appear to be skillfully hand-made. Soap bar contains 25-90% of surface-active substance base, suitable for skin cleaning, water-soluble and dispersible in water solid matrix, which contains, at least, 1 wt % of surface-active substance. Dispersion phase has the largest size within 3-70 mm. Hardness of solid phase measured at temperature 33-50°C, constitutes 1.9-2.5 bars, and ratio lambda, determined as solid phase hardness at temperature 25°C, divided by hardness at temperature 33°C, is more that 2.0. Dispersion phase constitutes 1-35 wt % of bar. In second variant, bar contains 25-90% of surface-active substance base, composed of fatty acids soaps, synthetic detergents and their mixtures, 0.1-15% of plastifying agent, 1 wt % of surface-active substance, 5-95 wt % of water-soluble or dispersible in water solid matrix, 0.25-15 wt % of hardening agent. Dispersion phase has largest size within 3-45 mm. Hardness of solid phase, measured at temperature 33-50°C, constitutes 1.9-2.5 bars, and ratio lambda, determined as solid phase hardness at temperature 25°C, divided by hardness at temperature 33°C, is more than 2.0. Dispersion phase constitutes 1-35 wt % of bar. Method includes formation of mixture, by adding two solid phases, mixture extrusion, cutting and moulding extruded mass in form of bar. Method of skin cleaning and moisturising, as well as method of deep cleaning, includes skin washing with soap bar and washing with water. ^ EFFECT: obtaining multi-phase soap bar, which appears to be skillfully hand-made and which can be manufactured by high-rate extrusion method. ^ 31 cl, 8 tbl, 4 ex |
