Abstract

The invention provides a vegetable-fat nano-emulsion prepared by a D-phase emulsifying method. The vegetable-fat nano-emulsion comprises, by weight percentage, 5-20% of polyol, 1-10% of emulsifier, 5-30% of vegetable fat and the balance water. The invention further provides a preparation method of the vegetable-fat nano-emulsion. The preparation method includes: mixing glycerin, butanediol or propylene glycol with the emulsifier, and heating to obtain a mixed component; heating the vegetable fat to obtain an oil-phase component, adding the oil-phase component into the mixed component, and stirring to obtain a gel-phase component; heating a water phase, then adding into the gel-phase component, mixing and stirring, and cooling to room temperature to obtain the O/W type vegetable-fat nano-emulsion, wherein the particle size of the dispersion-phase particles of the O/W type vegetable-fat nano-emulsion is 200-700 nanometers. The vegetable-fat nano-emulsion and the preparation method thereof have the advantages that the particle size of the vegetable-fat nano-emulsion is lowered, so that the vegetable-fat nano-emulsion can be favorably absorbed by the skin; the adding amount of the emulsifier in the vegetable-fat nano-emulsion is lowered, so that the irritation of the vegetable-fat nano-emulsion to the skin is lowered; in addition, the vegetable-fat nano-emulsion is good in stability.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a cosmetic and a preparation method thereof, in particular to a vegetable oil nanoemulsion prepared by a D-phase emulsification method and a preparation method thereof. Background technique [0002] Vegetable fats are usually liquid at room temperature. It has the effect of natural moisturizing and nourishing the skin. When applied to the skin, products containing vegetable oils can form a film on the skin surface to lock in moisture and moisturize. Most vegetable oils contain a large amount of unsaturated fatty acids and unsaturated fatty alcohols, which have good affinity with the skin and can penetrate into the stratum corneum of the skin through the intercellular space. While providing a smooth skin feel, they also moisturize and care for the skin. effect. In addition, vegetable oils are mostly extracted from natural plant organs, which has greater advantages i...
