Abstract
A composition embraces an oil, for instance, a mineral oil, animal oil, or plant or vegetable oil, in combination with an acetal that can release aldehyde functionality on aqueous contact. It may be used in a method for kill or control of bacterium or virus for a suitable part of a human being or animal subject. For example, a 5% mineral oil and 2,2'-trimethylenebis(1,3-dioxolane) mixture can be used as a microbiocidal lubricant for drill bits in dentistry, or a suitably formulated composition may be used topically.
Claims20
A composition of matter comprising a substantially non-aqueous oil in combination with an acetal that can release aldehyde functionality on aqueous contact, wherein the acetal is saturated and non-hydroxylated, and wherein the acetal is selected from among compounds of the group consisting of compounds of the following general formulae:
- ##STR2## Each "n" is 2 or 3, and Each "R" is independently at each occurrence lower alkyl or hydro in the formula I and independently at each occurrence lower alkyl in the formula II.
A composition of matter comprising mineral oil and 2,2'-trimethylenebis(1,3-dioxolane), in homogeneous mixture.
A method for kill or control of bacterium or virus comprising providing a composition of matter embracing a substantially non-aqueous oil in combination with an acetal that can release aldehyde functionality on aqueous contact, said acetal being selected from among compounds of the group consisting of compounds of the following general formulae:
- ##STR3## each "n" is 3, and each "R" is hydro in the formula I and independently at each occurrence lower alkyl in the formula II;
- and said acetal in said oil of said composition being provided in an amount effective to kill or control bacterium or virus, for a suitable part of a human being or animal subject, epidermally and/or integumentally, but extraneous said human being or animal subject, under conditions such that, when said composition contacts water proximate to said bacterium or virus or contacts said bacterium or virus itself, said kill or control is thus and there provided.
