No-ethanol essence aquose dispersion system

Abstract

The invention relates to an ethanol-free essence waterborne dispersion system, particularly to perfume, body spraying agent, deodorant, waterborne cosmetic composition, domestic detergent and air freshener. The essence waterborne dispersion system comprises the following component of (wt%): aroma materials 0.1-0.6%, phase dispersant 1-60%, and water 10-95%, wherein the aroma materials, phase dispersant and water form a low molecular weight dispersion system or a colloidal dispersion system. The dispersion system uses water as basic medium, the properly added phase dispersant (with high boiling point and slow evaporation) takes both cosolvent and stabilizer effects, so that the products can keep scent for a longer time. In addition, the products are normally not greasy and sticky, and the phase dispersant may not influence the quality of aroma materials and is not sensitive to air oxidation, so as to keep the natural color of perfume.

Description

technical field [0001] The invention relates to a perfume aqueous dispersion system, in particular to perfumes, body sprays, deodorants, aqueous cosmetic compositions, household cleaners and air fresheners. Background technique [0002] The traditional method of making perfume is to mix various essential oils with ethanol as a solvent to form a uniform and stable solution, that is, perfume. Because in the early days of perfume production, chemical technology was not as developed as it is today, so perfumers chose ethanol, a relatively easy-to-obtain chemical solvent. Ethanol has a low boiling point and strong volatility (the current trend is to reduce the use of volatile organic chemicals (VOC)), and can dissolve most organic essential oils, and can also play a certain role in freshness. It is indeed a good solvent However, ethanol itself has a pungent taste. Even after undergoing a high-cost redistillation process, its own taste can still be mixed with the fragrance of ess...

Problems solved by technology

But they have the following disadvantages: or the appearance is emulsion, which affects the traditional visual effect of perfume; or requires high concentration of surfactant, due to the viscous nature of surfactant, the viscosity of the product increases, and it is not particularly harmful to human health. beneficial; or due to the irritating nature of the solubilizer and the aggressive nature of the surfactant, the product is irritating to a certain extent and affects the olfactory characteristics; or other alcoholic compounds are used instead of ethanol as a solvent or solubilizer to avoid The names of ethanol perfumes confuse the original intention of alcohol-free perfumes
