Embodiment

[0111] The following examples further describe and demonstrate embodiments within the scope of the present invention. The examples given are for the purpose of illustration only and are not to be construed as limiting, as many variations thereof are possible without departing from the spirit and scope of the invention.

[0112] Table 1

[0113] With unsaturated C 18 Time Kill Efficacy of Variations in Soap (eg Oleic Acid) / Sodium Caprate Ratio.

[0114] In the mixture, sodium caprate was maintained at a fixed level to simulate a soap bar containing 16% by weight sodium caprate, and C 18 Sodium soaps vary from 0 to 22% by weight.

[0116]

[0117]

[0118] As demonstrated by the data in Table 1, when the unsaturated C 18 When the ratio of soap to caprate is less than 1.2, the unsaturated C 18 Sodium soaps of fatty acids begin to inhibit the biocidal efficacy of sodium caprate (which we define as the log 10 reduction of at least 1.0, preferably at ...

Abstract

The invention relates to bar composition comprising minimum floor levels of C10 soap while minimizing ratio of unsaturated C18 soap to caprate. Such bars provide enhanced rapid, antibacterial activity. Disclsoed is a soap bar composition comprising: a) 25 to 85%, preferably 35 to 75% by weight of C8 to C24 fatty acid soap comprising: (i) C10 soap at 8% or 15% or greater, more preferably 16 to 32% by weight of total bar composition; and, (ii) unsaturated C18 soap, wherein weight ratio of said unsaturated C18 soap to C10 (caprate) soap is 1.2 to 0.1. b) 1 to 45 % organic and inorganic adjuvant materials by weight of the composition; and, c) 5 to 30%, preferably 13 to 28% water by weight of the composition, wherein excess of C10 soap to unsaturated C18 soap is at least 6%.

Description

technical field [0001] The present invention relates to fatty acid-based soap bars, which are generally prepared by saponification (e.g., neutralization) of triglyceride oils comprising fatty acid esters of different chain lengths (attached to the glyceryl groups of the triglyceride oils). ). It also involves using a minimum amount of a particular chain length (e.g., C 10 ), while minimizing others (including minimizing the amount of chain length and / or the level of saturation or unsaturation of certain fatty acid esters) to enhance antibacterial activity. Background technique [0002] Commercially available soap bars typically contain one or more "soaps" which, for the purposes of describing this component of the bar of the present invention, have the meaning commonly understood in the art: monovalent salts of monocarboxylic fatty acids. As noted, they are generally formed by saponification of triglyceride oils. The counterions of the salts typically include sodium, pota...
