Embodiment approach

[0054]As used herein, unless the context clearly dictates otherwise, the term "or" is an inclusive operator and is equivalent to the term "and / or". Unless the context clearly dictates otherwise, the term "based on" is not exclusive and allows for being based on additional factors not described. In the specification, the recitation "at least one of A, B, and C" includes embodiments comprising: A, B, or C; multiple instances of A, B, or C; or A / B, A / C, B Combinations of / C, A / B / B / B / B / C, A / B / C. Additionally, throughout the specification, the meanings of "a" and "the" include multiple references. The meaning of "in" includes "in" and "on".

[0055] It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first object, component or step could be termed a second object, component or ...

[0122] Aspects of the disclosure can be further understood by reference to the following examples. These examples are illustrative and not intended to be limiting embodiments thereof.

example 1

[0124] Table 1 illustrates the CPC-ZnCl 2 Evaluation of the antibacterial efficacy of the complexes in the presence of anionic surfactants. Specifically, for CPC-ZnCl in the presence of SLS as follows 2 Antibacterial efficacy of the complex and ZnCl 2 Individually compared with CPC: Human saliva was collected and diluted three times with deionized water, centrifuged and decanted to yield a translucent solution of oral bacteria. 10mg (+ / -0.7mg) antibacterial component (CPC-ZnCl 2 Complexes, CPC and ZnCl 2 ) was combined with 20 mg (+ / −0.9 mg) of 30% by weight SLS in water and 5 ml of the prepared oral bacteria solution. A negative control was also prepared by adding 20 mg (+ / - 0.9 mg) of 30% by weight SLS in water and 5 ml of the prepared oral bacteria solution to deionized water instead of the antibacterial component. The samples were then placed in a 37°C oven and shaken at 100 RPM for 30 minutes. 200 μL of Alamar Blue dye was then added to each sample and placed back i...

Abstract

Described herein are complexes comprising a cationic antibacterial agent and a metal salt, personal care compositions comprising same; along with methods of making and using these complexes and compositions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Provisional Application No. 62 / 607355, filed December 19, 2017, the entire contents of which are hereby incorporated by reference. Background technique [0003] Antimicrobial agents are commonly incorporated into a variety of personal care compositions, such as bar soaps, body washes, shampoos and underarm products, to destroy or retard the growth of bacteria on the skin or hair and to combat malodor. [0004] Many antimicrobials are cationic in order to interact with negatively charged microbial cell membranes. However, since most bar soaps are inherently strongly alkaline, antimicrobial agents containing acidic or cationic functional groups may be inactivated when incorporated into bar soap compositions. Similarly, personal care formulations often include anionic soaps or surfactants, which are also capable of inactivating cationic antimicrobials. [0005] Accordingly, it...
