摘要: 将锌钛复合浆料应用到防晒霜配方中,考察了所得防晒霜的防晒性能、肤感及对配方理化性质(pH,耐热、耐寒及离心稳定性)的影响,并与市售TiO2、ZnO混合粉体、浆料进行对比。结果表明,在防晒性能方面,配方中活性物质量分数为8%时,含锌钛复合浆料配方的SPF值可达24,PA值为6,而含市售TiO2、ZnO混合粉体、浆料配方的SPF和PA值偏低,锌钛复合浆料同时具有协同增效屏蔽紫外线的能力(SPF值同比增长8%);在配方稳定性方面,经过冻融循环实验后,pH维持在7.2左右,解决了传统ZnO与水形成碱性络合物导致配方pH偏高的缺点;在感官评价方面,含锌钛复合浆料的配方,水润感较强,厚重感和油腻感较低,在涂抹时和涂抹后,起白不明显。

Abstract: Zinc titanium composite slurry was applied to sunscreen formula,the sunscreen properties,skin feel and impact on physical and chemical properties (pH,heat resistance,cold resistance and centrifugal stability) of the sunscreens obtained were investigated.The investigated sunscreens were compared with commercially available TiO2,ZnO mixed powder and slurry.Results showed that the SPF value of the zinc-titanium composite slurry was 24 and the PA value was 6 when the active ingredient mass fraction was 8%,however,the SPF and PA values of formulations containing commercially available single mixed powder and slurry are relatively low,and the zinc-titanium composite slurry also has the synergistic UV shielding capability (SPF value increased by 8% compared with the same period of last year).In the aspect of formulation stability,after the freeze-thaw cycle experiment,the pH value can be maintained at about 7.2,which solves the disadvantage that the traditional complex formation of ZnO with water leads to the high formula pH.In the sensory evaluation,the formula containing zinc-titanium composite slurry has strong sense of moisture,low heavy and greasy sense,and unobvious white phenomenon after used.

Key words: sunscreen cosmetics additives, zinc-titanium composite slurry, skin feel evaluation
