Abstract
The invention provides a long-acting moisturizing type moisturizing cream and a preparation method thereof, wherein the cream comprises the following components in parts by weight: oil phase: 45-50 parts of chinaroot greenbrier seed oil; 15-20 parts of light liquid paraffin; 3-5 parts of polydimethylsiloxane; 1-2 parts of cetearyl alcohol; 15-20 parts of modified microcapsule particles; water phase: 55-60 parts of deionized water; 15-20 parts of glycerol; 6-8 parts of sodium hyaluronate; 6-8 parts of chitosan; the modified microcapsule is prepared by taking maltodextrin as a wall material and monoglyceride and algal polysaccharide as core materials through spray drying. The prepared microcapsule material with the slow release structure can effectively coat and stay on the surface layer of skin, thereby prolonging the moisturizing performance and the moisturizing duration.
Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a long-acting moisturizing type moisturizing cream and a preparation method thereof.
Background
The human skin is like the human barrier, is tough, soft and elastic, protects tissues and organs in the body from external mechanical, physical, chemical or biological invasion or stimulation, has natural moisture retention performance, and plays an irreplaceable role in keeping human moisture. The skin is divided into three parts, namely epidermis, dermis and subcutaneous tissue, and each layer has different physiological effects on the moisturizing performance of the skin. The moisturizing is to prevent the loss of moisture in the skin and to absorb moisture in the external environment, thereby achieving the purpose of keeping the skin to contain a certain amount of moisture. The main source of skin stratum corneum moisture is sweat secreted by sweat glands. The oily film on the skin surface can prevent the evaporation of water, thereby maintaining the water contained in the stratum corneum of the skin.
Conventional skin moisturizing regimens typically utilize the exogenously supplied source of moisturizing agents to replenish the water lost to the stratum corneum. The moisturizer mainly comprises glycerin, sodium pyrrolidone carboxylate, hydrated gel, hyaluronic acid and derivatives thereof and the like, and can rapidly improve the water replenishing and locking functions of the stratum corneum of the outermost layer of the skin, so that the moisturizer achieves the effect of rapid moisture preservation. However, such materials do achieve long-lasting moisturization. It has a moisturizing effect for a short time only after application, so it is necessary to improve it effectively.
