Study On Preparation And Properties Of Polysaccharide From Mussel Shells Seaweed Mask

Mussel shells contain a variety of amino acids and trace elements of human needs, and wakame so-called "natural spirulina" because of high nutritional value. Use the abandoned a mountain of mussel shells resources, add crony seaweed polysaccharides and auxiliary materials, can be made into the physical and chemical properties, practical performance manner mask, waste. This study use of zhoushan abandoned mussel shells shattered into shell powder, seaweed polysaccharides extract wakame active substances, in both the basis of the composition, as the mask again with other auxiliary materials distribution, processing and preparation of seaweed polysaccharides in mussel shells mask. This study optimized the crony seaweed polysaccharides extraction technology and determination of the amino acids and trace elements content of mussel shells powder, mussel shells powder was studied by the experimental method of composition, particle size and thermal decomposition rules, it is concluded that mussel shells are optimized by the test of face of seaweed polysaccharides formula, and the determination of the sensory index of the mask formula, physical and chemical indicators, the skin irritation test, acute oral toxicity test and moisturizing effect. The main research conclusion as follows:1. Similar pearl mussel shells powder powder contains many amino acids beneficial to human body. Among them, serine, valine can regulate endocrine, enhance immunity and anti-aging, leucine and valine, isoleucine have repair organization, promote growth, regulate blood sugar to lose weight and whiten skin, and so on.2. Mussel shells powder like pearl powder contain a variety of human body needs, and metallic elements such as copper, iron, zinc, strontium. Among them, the copper element has the function of radiation resistance, cancer prevention, strontium element has the function of prevent hardening of the arteries and prevent the formation of blood clots, zinc have skin repair function. Sample test results showed that mussel shells of lead, mercury element content is lower than the national standard.3. The optimal extraction process conditions of seaweed polysaccharides crony, rising ratio of material liquid(g/ml), the temperature is 80 ?, time of 1.5 h, for pH = 8.0. Under the condition of the extraction of crony, seaweed polysaccharides extraction yield.4. Seaweed polysaccharides mussel shells mask optimization formula of mussel shells seaweed polysaccharides powder 0.7 g, 0.7 g, 1.0 g, polyvinyl alcohol, sodium carboxymethyl cellulose(CMC) 1.6 g, glycerin E1 ml 6 ml, vitamin, sodium benzoate, 1 g, deionized water, 100 ml, the essence of a small amount.5. According to this study to optimize formula preparation of mussel shells of face of seaweed polysaccharides mild stimulation, without any side effects, and is suitable for various kinds of human body skin(including allergic skin), moisturizing effect is significantly better than that of aloe vera gel and cucumber face film. Can obviously increase the facial skin moisture, make skin become smooth and exquisite, water embellish whiten, improve facial skin. Stop using a week after a significant rebound, is healthy and beauty skin care products.
