A process for producing a hydroxyfatty acid polyhydric alcohol ester, which comprises; adding at least one polyhydric alcohol represented by the formula (III) or (IV), ##STR1## wherein R.sub.5 represents a hydrogen atom or a methyl group, R.sub.6 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and m and n represent integers from 1 to 6, to hydrated Sophorolipid which is a fermentation product of Torulopsis bombicola; distilling off water under reduced pressure; and subjecting the resulting mixture to an alcoholysis reaction by adding an acid catalyst to the mother liquor.

Process for producing a hydroxyfatty acid ester

Compounds having the formula: ##STR1## wherein R.sub.1 is alkyl or alkenyl containing 1 to 20 carbon atoms, X is S, SO or SO.sub.2, and R.sub.2 and R.sub.3, which can be the same or different, are hydrogen, alkyl containing 1 to 20 carbon atoms, oxyalkylene containing 1 to 20 units of ethylene oxide or propylene oxide, 2-sulfoethyl or a salt thereof, or 2-carboxyethyl or a salt thereof, are incorporated, as a preservative or anti-microbial agent in compositions that are subject to deterioration by the action of micro-organisms, excluding foods and medicines.

Compositions containing beta substituted acrylic acid amides as

Compounds having the formula ##STR1## wherein R.sup.1 is alkyl having 1 to 20 carbon atoms, preferably 6 to 20 carbon atoms, and R.sup.3 and R.sup.4 are hydrogen, alkyl having 1 to 20 carbon atoms, preferably 1 to 6 carbon atoms, or substituted alkyl having 2 to 6 carbon atoms and substituted by hydroxyl or sulfo salt. The compounds are prepared by reacting R'SH with acetylene monocarboxylic acid and then reacting the thus-formed intermediate with an amine. The compounds possess surface active and antibiotic properties.

Germicidal herbicide for agriculture and horticulture

A germicidal herbicide for agricultural and horticultural purposes, which comprises at least one compound as an active ingredient, of the formula (I): ##STR1## wherein R.sub.1 represents an alkyl or alkenyl group having 1 to 20 carbon atoms, X represents S, SO or SO.sub.2, and R.sub.2 and R.sub.3 which may be the same or different representing hydrogen, an alkyl group having 1 to 20 carbon atoms, an oxyalkylene group having 1 to 20 units of ethylene oxide or propylene oxide, 2-sulfoethyl or a salt thereof, or 2-carboxyethyl group.

A herbicide which comprises at least one compound as an active ingredient of the formula (I); ##STR1## wherein X represents a halogen atom or an alkyl sulfinyl or alkyl sulfonyl group having 1 to 3 carbon atoms, n represents an integer of 0- 3, Y represents SO or SO.sub.2, and R represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms.
