Abstract: Novel high absorption body powder compositions comprising rice hulls ground to a particle fineness such that the material passes through a 200 mesh sieve, and preferably passes through a 325 mesh sieve, as the basic and main powder constituent.

Abstract: An oral composition effective to promote oral hygiene containing as an anticalculus agent a water soluble oligomer of the formula ##STR1## wherein M is a water soluble orally acceptable cation;R.sub.1, r.sub.2, r.sub.3 and R.sub.4 are independently H, methyl or ethyl;Y is at least one hydrophilic member of the group consisting of --COOM.sub.1, --CONH.sub.2, and --CH.sub.2 OH:X is at least one hydrophobic member of the group consisting of --CN, --COOR, --COOR.sub.5 OR, --CONHR, --COONHR.sub.5 COR, and --OOCR;M.sub.1 is H or M;R is C.sub.1-8 alkyl;R.sub.5 is C.sub.1-4 alkylene;A is 0-7; andA+b is about 4-15.

Abstract: An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent and an additive which reduces staining of dental surfaces without substantially diminishing the antibacterial and antiplaque activity of the agent. Bis-biguanido hexanes, such as chlorhexidine and alexidine, and quaternary ammonium salts, such as benzethonium chloride and cetyl pyridinium chloride are typical examples of antibacterial agents. The antistain additive is a water soluble oligomer of the formula ##STR1## wherein M is a water soluble orally acceptable cation;R.sub.1, r.sub.2, r.sub.3 and R.sub.4 are independently H, methyl or ethyl;Y is at least one hydrophilic member of the group consisting of --COOM.sub.1, --CONH.sub.2, and --CH.sub.2 OH;X is at least one hydrophobic member of the group consisting of --CN, --COOR, --COOR.sub.5 OR, --CONHR, --COONHR.sub.5 COR, and --OOCR;M.sub.1 is H or M;R is C.sub.1-8 alkyl;R.sub.5 is C.sub.1-4 alkylene;a is 0-7; anda+b is about 4-15.
