KR-102964868-B1 - ANTIMICROBIAL NATURALLY-DERIVED ESSENTIAL OIL-BASED DEODORIZER AND MANUFACTURING METHOD THEREOF

Abstract

The present invention relates to a method for manufacturing a gel-type deodorizer utilizing the synergistic antibacterial effect of pine needle scent and pine oil, and more specifically, to a method for manufacturing an eco-friendly deodorizer having excellent antibacterial power and persistence through stepwise processing and optimal blending of naturally derived antibacterial components. The deodorizer of the present invention comprises 8 to 12 parts by weight of ethanol, 0.3 to 0.5 parts by weight of IPBC, 0.3 to 0.5 parts by weight of 2-phenoxyethanol, 0.6 to 1.0 parts by weight of gellan gum, 0.005 to 0.009 parts by weight of tannin, 0.01 to 0.04 parts by weight of zinc sulfate, 6 to 9 parts by weight of castor oil, hydrogenated, ethoxylated, 1.5 to 2.5 parts by weight of fragrance (pine oil), and 3 to 4 parts by weight of pine needle scent, with the remainder being purified water, for a total of 100 parts by weight. The core technical features of the present invention are the formation of a gel matrix based on gellan gum, the sequential formation of solvent phases of ethanol and 2-phenoxyethanol, the realization of a synergistic effect through the simultaneous addition of multiple antimicrobial components, the securing of emulsion stability through an O/W type emulsion, and the establishment of an optimal fragrance profile through the stepwise addition of pine oil and pine needle scent. In particular, the combination of a sustained-release zinc sulfate system via microencapsulation technology and enhanced bioavailability of IPBC via nano-dispersion technology exhibits significantly improved antimicrobial persistence compared to existing products. The deodorizer produced by the manufacturing method according to the present invention exhibits an antibacterial rate of 99% or more within 24 hours against Escherichia coli and Staphylococcus aureus, maintains stability for more than 24 months at room temperature, and is an excellent product that ensures safety for the human body and the environment by using only naturally derived ingredients.

Description

Antimicrobial Naturally Derived Essential Oil-Based Deodorizer Providing Antimicrobial Properties and Method for Manufacturing the Same The following examples relate to a natural essential oil-based deodorant that provides antibacterial properties and a method for manufacturing the same. Generally, deodorizers are products used to remove or reduce odors and are widely used in various fields, including household, commercial, and industrial sectors. Conventional deodorizers typically removed odors primarily through chemical neutralization, adsorption, or masking methods. Chemical neutralization deodorizers work by chemically reacting with odor components to convert them into odorless compounds; however, they are effective only against specific odor components and have limited efficacy against a wide range of odors. Adsorption deodorizers physically adsorb odor molecules using porous materials such as activated carbon or zeolite, but they have the disadvantage that their effectiveness decreases rapidly once the adsorption capacity is saturated and regeneration is difficult. Masking deodorizers use strong fragrances to mask odors, but this method only provides a temporary masking effect rather than fundamental odor removal, leading to the problem that the odor would reappear over time. Additionally, there was the issue that the fragrances themselves could cause other odor pollution. Recently, there has been increasing interest in deodorizers that also possess antibacterial effects, as a significant portion of odors are caused by the proliferation of bacteria. Conventional antibacterial deodorizers were primarily manufactured using alcohols, quaternary ammonium salts, or synthetic antibacterial agents, but these chemically synthesized antibacterial agents could cause safety concerns regarding the human body and environmental pollution problems. Although research on naturally derived antimicrobial ingredients has been actively conducted, most natural antimicrobial ingredients have problems such as relatively weak antimicrobial activity, poor stability, and a decrease in activity during the formulation process. In particular, essential oils have technical limitations, including high volatility making it difficult to expect sustained antimicrobial effects and ensuring stability in water-soluble formulations. Furthermore, conventional deodorizer manufacturing methods were limited to simply mixing ingredients, resulting in a problem where the synergistic effects between them could not be fully utilized. In particular, there was a lack of systematic manufacturing processes that simultaneously considered the synergistic effects of antimicrobial ingredients and formulation stability.
