Preservative composition containing oriental blueberry extract, and preparation method and application thereof

Abstract

The invention discloses a preservative composition containing an oriental blueberry extract as well as a preparation method and application thereof. The preservative composition containing the oriental blueberry extract is composed of an oriental blueberry extract, a synergistic agent and a solvent; the synergistic agent comprises at least one selected from polyhydric alcohols or aromatic alcohols; the solvent comprises at least one selected from alcohols or water; content of the oriental blueberry extract is 2-28% in percentage by weight; content of the synergistic agent is 3-55% in percentage by weight; and the solvent accounts for the balance. The preservative composition containing the oriental blueberry extract is good in stability. The oriental blueberry extract contained in the preservative composition is a food-grade natural plant preservative which has little damage to the human body; the synergistic agent is an alcohol substance; and the solvent is also an alcohol substance. Moreover, the alcohol substances themselves have bacteriostatic effects, so that, the synergistic agent and the solvent are capable of improving dissolution of polyphenols and flavonoids in the oriental blueberry extract as well as enhancing bacteriostatic effects of the oriental blueberry extract on bacteria and fungi.

Description

technical field [0001] The invention relates to the technical field of antisepsis, in particular to a preservative composition containing an extract of the black rice tree and its preparation method and application. Background technique [0002] Preservatives are one of the indispensable components of cosmetics, which can ensure that cosmetics will not deteriorate due to microbial contamination during production, storage and use. The "Safety and Technical Specifications for Cosmetics" (2015 Edition) reduced the number of preservatives allowed to be used in cosmetics in my country from 56 to 51, and made strict restrictions on their dosage and scope. Among them, there are only more than 20 kinds of preservatives commonly used in cosmetics, and the most frequently used preservatives are parabens, phenoxyethanol, benzoic acids, methylisothiazolinone and sorbic acid. The preservatives used in the prior art are mainly artificially synthesized chemicals, but these preservatives a...

AI Technical Summary

Problems solved by technology

[0005] However, there are also some other problems in the preservative composition, such as the residue of the extract solvent or the use of a large amount of addition, and the antiseptic effect requires supplementary or synergistic ingredients to achieve the effect of chemical preservatives

Since the leaf extract of black rice tree is added to cosmetics, it needs to be added in a large amount to achieve the same antiseptic effect. However, in actual use, it is difficult to really replace artificial synthetic chemical preservatives. Therefore, it is necessary to add some Synergistic ingredients to overcome overuse of preservatives
