Optically clear dentifrice - contg aluminosilicate particles in a gelled medium of the same refractive index

摘要

Prod. contains 5-50 wt.% polishing agent particles of water-insol material in a gelled med. of the same R.I where the agent, invisible in the med. is of synthetic complex amorphous alkali(ne earth) metal aluminosilicate (Si combined with Al) of R.I 1.44-1.47 and moisture content is not >20 wt.% and alkali(ne earth) metal oxide content is not >10 wt.%. The gelling agent is 0.5-5 wt.% of a complex silicious clay.
