Color stable preservative composition

Abstract

Provided herein is a disclosure that blending a dicarboxylic acid with a ketonic acid, used as a preservative in a end-use formulation, such as a personal care product, can mitigate the discoloration of the end-use formulation which is caused by an elevated pH in the end-use formulation or in end-use formulations which have been exposed to elevated temperature.

Description

[0001] field of invention [0002] The present disclosure relates to preservative compositions that resist discoloration when placed in an article to be preserved. [0003] Background of the invention [0004] Preservative compositions for protecting and preserving end-use articles against bacterial or fungal attack are known in the art. These preservative compositions have wide applications in fields such as personal care products, household and industrial products, health and hygiene products, and pharmaceuticals. Conventional preservative blends use conventional active ingredients that provide the desired good bactericidal and fungicidal properties. [0005] Ideally, preservatives have a broad spectrum of activity against all types of microorganisms at various pH levels. The preservative should also have high potency so that a minimum amount of preservative can be used to save costs and avoid or reduce any possible adverse effects caused by the preservative. Furthermore, ...
