Description

Nourishing and repairing bath foam and preparation method thereof Technical Field The application relates to the technical field of cosmetics, in particular to nourishing and repairing bath foam and a preparation method thereof. Background In the field of personal cleaning and nursing, amino acid body wash has become a mainstream choice for dry muscle and sensitive muscle groups due to the mild and non-irritating properties. However, the prior amino acid bath cream has the common core technical pain point that firstly, the cleaning and nourishing effects are unbalanced, most products only focus on the mild cleaning property of amino acid surfactants, the barrier repair and long-acting moisture preservation which are needed for the dry muscle are not enough, the problems of skin tightness, dryness and even desquamation are easy to occur after cleaning, and the deep nourishing requirement of daily nursing of the dry muscle is difficult to meet. Part of the products are optimized in texture or prolonged in shelf life, and the added emulsifying agent and preservative have high concentration, or the pH value of the formula deviates from the physiological range of skin, so that skin barrier is easily stimulated, and the risks of sensitive myoredness and dry itching are increased. Therefore, research and development of the moisturizing bath foam with mild, clean and high-efficiency repairing functions, stable formula and high safety becomes a technical problem to be solved in the current industry. Disclosure of Invention Aiming at the defects of the prior art, the application provides a nourishing and repairing bath lotion and a preparation method thereof, wherein a double-layer compound microcapsule containing a ceramide NP/phytosterol outer layer, a sea buckthorn fruit oil/vitamin E inner layer and a beta-cyclodextrin wall material is prepared by a step-by-step embedding method, and is prepared by a specific process by matching serine, glycine and alanine compound amino acid with a cocoyl sodium malate/polyglycerol-4 laurate mild surfactant system, so that barrier repairing, moisturizing and moisturizing are realized, and the stability and mildness are excellent. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, the application provides a nourishing and repairing shower gel, comprising the following components: The sea buckthorn fruit oil microcapsule comprises, by mass, 5% -7% of compound amino acid, 8% -10% of sodium cocoyl malate, 4% -6% of sea buckthorn fruit oil compound microcapsule, 4% -6% of sorbitol, 0.2% -0.4% of sodium hyaluronate, 0.7% -0.9% of polyglycerol-4 laurate, 0.6% -0.8% of preservative, 0.08% -0.12% of carbomer, 0.08% -0.12% of triethanolamine and the balance deionized water, wherein the sea buckthorn fruit oil compound microcapsule is a double-layer microcapsule obtained by adopting a step embedding method, the double-layer microcapsule comprises an outer layer core material, an inner layer core material and a wall material, the outer layer core material comprises ceramide NP and phytosterol, the inner layer core material comprises sea buckthorn fruit oil and vitamin E, and the wall material is beta-cyclodextrin. In the application, beta-cyclodextrin forms stable coating on sea buckthorn fruit oil and vitamin E by virtue of a hydrophobic cavity through Van der Waals force and hydrogen bond action, and ceramide NP and phytosterol are subjected to interfacial self-assembly on the surface layer on the surface of an inclusion core through mediation of ethanol to form a lipid composite coating adsorbed on the surface of the beta-cyclodextrin. In the use process, the hydrophobic effect among molecules in the lipid composite layer is destroyed through weak mechanical friction during bath, so that the outer layer lipid is promoted to be released preferentially, the surface temperature of a human body and the neutral pH environment regulated by triethanolamine act together, the slow dissociation of the beta-cyclodextrin inclusion system is promoted, and the problem of synchronous release of core materials is avoided. The ceramide NP and the phytosterol which are released preferentially are embedded into the lipid bilayer of the skin stratum corneum, which is arranged irregularly due to lipid loss caused by cleaning, through intermolecular force, so that intercellular lipid is supplemented, the damaged skin barrier structure is repaired, and the instant barrier repairing effect is realized. The sea buckthorn fruit oil and vitamin E in the inner core are continuously released in the subsequent inclusion, the vitamin E is used as a primary antioxidant, lipid peroxidation free radicals in the skin cuticle are captured through phenolic hydroxyl hydrogen transfer, the lipid peroxidation chain reaction is stopped, flavonoid and polyphenol active ingredients in the sea buckthorn fruit oil synchronously clear oxygen free radicals, the oxidation c
