Skin care lotion with moisturizing and anti-aging functions and preparation method thereof

Abstract

The invention discloses a skin care lotion with moisturizing and anti-aging functions and a preparation method thereof. The preparation method comprises the following steps: firstly preparing porous microspheres by polylactic acid, polyepoxyhexane and other components; separately coating an anti-aging component and a moisturizing component into nano composite microspheres A and nano composite microspheres B, and loading the nano composite microspheres A and nano composite microspheres B on the porous microspheres to obtain modified microspheres; preparing a base liquid by mixing chitosan and beta-sodium glycerophosphate; and adding the modified microspheres into the base liquid to obtain the skin care lotion. Through the synergistic effect of the porous microspheres, the nano composite microspheres A, the nano composite microspheres B and the base liquid, the prepared skin care lotion has certain light stability, slow release properties and antibacterial properties, is simple in principle, is convenient to prepare, is not added with preservatives and flavors, is also relatively friendly to the sensitive skin, and has very good application prospects.

Description

technical field [0001] The invention relates to the field of beauty cosmetics, in particular to a skin care liquid with moisturizing and anti-aging functions and a preparation method thereof. Background technique [0002] The age of 18-25 is the peak of the state of various tissues and functions of the human body, and the skin will also be in a ruddy, plump, and shiny state, but as time goes by, human beings will gradually age, especially after the age of 25, the skin begins to enter In the state of natural aging, the causes of aging mainly include ultraviolet rays, air pollution, heavy metal residues, and the decline of the epidermal barrier function, which reduce the skin's moisture retention ability, cause epidermal atrophy and wrinkles, and face dullness and other problems. [0003] In order to delay the skin problems caused by aging, people began to flock to cosmetics with anti-aging and moisturizing effects, which led to a research boom in anti-aging cosmetics in China...

AI Technical Summary

Problems solved by technology

[0003] In order to delay the skin problems caused by aging, people began to flock to cosmetics with anti-aging and moisturizing effects, which led to a research boom in anti-aging cosmetics in China in recent years; the preparation process of moisturizing and anti-aging skin care solutions on the market is mainly divided into There are two types: one is the traditional skin care lotion obtained by directly emulsifying the oily components under high temperature conditions, and then mixing them into the water phase; the other is directly mixing the water phase, oil phase, surfactants, and co-surfactants. The microemulsion skin care lotion that spontaneously forms a translucent or transparent system; whether it is a traditional skin care lotion or a microemulsion lotion, the synthetic method of "steaming in one pot" is adopted, but a considerable part of the moisturizing and anti-aging components are harmful to the skin. Sensitive to pH, sensitive to light, and sensitive to temperature, if not stored properly, it will easily lead to deterioration of the skin care lotion, and at the same time, undetectable adverse reactions may occur between functional components, causing allergies

[0004] Furthermore, traditional skin care lotions are directly applied to the face when used, and a large amount of nutrients are covered on the skin in a short period of time, and the skin has no time to absorb them, and these nutrients become a breeding ground for bacteria, leading to the occurrence of acne and acne
