Problems solved by technology

At present, there are many types of moisturizing lotions on the market, with different moisturizing effects. Common moisturizing ingredients such as glycerin, butylene glycol and other polyols, as well as trehalose, dextran, sodium hyaluronate, etc., combined with moisturizing oils such as vaseline, Caprylic acid / capric triglyceride, isononyl isononanoate, etc. are emulsified. When used on the skin, the affinity with the lipid bilayer structure of the stratum corneum is not high, which is not conducive to the penetration and conduction of active substances, so that the skin cannot last for a long time. maintain a high moisture content

Abstract

The invention discloses emulsion with a long-lasting moisturizing effect and a preparation method thereof. The emulsion is prepared from, by weight, 10-20% of long-lasting moisturizing compounds, 55-75% of solvents, 1-5% of emulsifiers, 5-25% of emollient oil, 0.1-1.5% of stabilizers, 0.01-1% of pH adjuster, 1-10% of skin conditioners, 0.1-1% of preservative and 0.03-0.5% of aromatic. The emulsionis characterized in that moisturizing combined components include extracts of purple coneflower, extracts of sugar maple, filtrates of yeast/rice fermentation products, sodium lauroyl lactylate, ceramide 3, ceramide 6II, ceramide 1, phytosphingosine and phytosterols; by optimizing the compounding and increasing the proportion of the long-lasting moisturizing compound, a moisturizing effect lasting for 4-8 hours is achieved.
