A dentifrice composition is provided containing a quaternary ammonium organosiloxane having the formula ##STR1## wherein R.sup.1 is an alkoxy group having from 1 to 5 carbon atoms, R.sup.2 is an alkylene group having from 1 to 25 carbon atoms, and R.sup.3, R.sup.4 and R.sup.5 are, individually, alkyl groups of from 1 to 25 carbon atoms, and X is an anion, preferably selected from chlorine, bromine fluorine and iodine. A method of inhibiting plaque formation on teeth in an oral environment is also provided.

Compositions and methods for inhibiting plaque formation

Sunscreening compositions are disclosed which comprise a pharmaceutical extending medium having incorporated therein a substantive, dermally non-irritating, ultraviolet light absorbing compound which is a polyfunctional organic molecule containing two or more ultraviolet absorbing moieties connected by two or more polar linking groups to one or more aliphatic bridging groups. These sunscreening compositions are resistant to removal by water and mild abrasion but are readily removed by soap and water.

Sunscreening compositions

A microcapsule insecticide composition comprising microcapsules each having a polyurea shell wall including as an integral part of said shell a photostable ultraviolet light absorbent compound with a log molar extinction coefficient of from about 2 to about 5 with respect to radiation having wave lengths in the range of from about 270 to 350 nanometers and a liquid fill capable of slowly permeating the shell and comprising a pyrethroid and a biological synergist therefor.

Microcapsule insecticide composition

Dermal protective compositions are disclosed which comprise a pharmaceutical extending medium having incorporated therein a substantive, dermally non-irritating compound which is a polyfunctional organic molecule containing one or more fluorocarbon-containing groups joined by one or more polar linking groups to a polyvalent organic radical. When applied to skin, these compositions provide repellency against a wide variety of dermal irritants and are resistant to removal by mild abrasion and/or detergent solutions.
