椰子油脂质体保湿霜的制备和性能测试

Preparation and properties test of moisturizing cream based on coconut oil liposome

制备了椰子油脂质体并对其粒径分布及形态进行测定。将其应用于保湿霜的制备,对保湿霜进行了感官指标、理化指标、保湿性和抗氧化性测定。结果表明,椰子油脂质体粒径主要分布在10μm,形态为圆形或椭圆形结构;在相对湿度43%±1%条件下,椰子油脂质体保湿霜保湿率可达65.84%±0.2%,且对DPPH自由基、羟自由基、超氧自由基清除率分别为5.98%±0.3%,63.64%±0.2%和14.10%±0.2%,均高于椰子油保湿霜,说明椰子油脂质体保湿霜能提高保湿霜的保湿性和抗氧化性。

Coconut oil liposome was prepared and its particle size distribution and morphology were measured.The coconut oil liposome was applied to the preparation of the moisturizing cream,of which the sensory index,physical and chemical indicators,moisture retention and anti-oxidation were tested. It is found that the size of coconut oil liposome is mostly 10 μm and the morphology structure is spherical or elliptical. Under the condition of relative humidity of 43% ± 1%,the moisture efficiency of the moisturizing cream based on coconut oil liposome can reach 65. 84% ± 0. 2%,and the scavenging rates of DPPH,hydroxyl and O^2- radicals are5. 98% ± 0. 3%,63. 64% ± 0. 2%,and 14. 10% ± 0. 2%,respectively,which are all higher than that of coconut oil moisturizing cream. This indicates that the moisturizing cream based on coconut oil liposome can enhance the properties of moisture retention and anti-oxidation.
