超细珍珠粉制备Pickering乳液的影响因素研究 Study on the influence factors of Pickering emulsions stabilized by ultrafine pearl powder 张倩洁,沈兴亮,张婉萍 2021 (1):  1-9.  doi: 10.3969/j.issn.1001-1803.2021.01.001 摘要 ( 443 )   HTML ( 149 )   PDF(2372KB) ( 494 )   以天然来源的超细珍珠粉为原料,成功制备了稳定性较强的Pickering乳液,系统考察了珍珠粉用量、油水质量比、水相无机盐浓度对Pickering乳液形成及稳定性的影响。结果表明：随着超细珍珠粉用量的增加,乳液稳定性逐渐增强,较佳加入量为2.5%;超细珍珠粉具有制备高内相Pickering乳液的潜力,最大油水质量比可达8∶2,随着油水质量比的增加,乳液稳定性先增强后减弱,当油水质量比为4∶6时,乳液离心稳定性最高;水相氯化钠浓度较低时,对乳液稳定性无明显影响;当氯化钠浓度为20 mmol/L时,乳液离心稳定性增强,氯化钠浓度高于此值时,乳液离心稳定性显著降低。 In this paper, Pickering emulsions with excellent stability was prepared by ultrafine pearl powder. The effects of pearl powder dosage, oil-water mass ratio and aqueous inorganic salt concentration on the formation and stability of Pickering emulsions were systematically investigated. The results show that the stability of the emulsion increases with the increase of the mass fraction of ultrafine pearl powder, and the preferred addition amount is 2.5%. Ultrafine pearl powder has the potential to prepare high internal phase Pickering emulsions with a maximum oil-water mass ratio of 8∶2. With the increase of the oil-water mass ratio, the stability of the emulsion is firstly enhanced and then weakened, which reaches the highest centrifugal stability when the oil-water ratio is 4∶6. The stability of the emulsion is not affected obviously when the concentration of sodium chloride in aqueous phase is low. The centrifugal stability of the emulsion increases when the concentration of sodium chloride is 20 mmol/L and decreases as sodium chloride concentration continues to increase. 数据和表 | 参考文献 | 相关文章 | 计量指标

The use of sunscreen cosmetics can be very useful in reducing such injury. However, organic sunscreen agents tend to be allergenic, while inorganic sunscreen agents make people feel bad and have inhalation hazard. Therefore, plant extracts with sunscreening effect are being widely explored. The main mechanism of UV damage to the skin are sunburn and photoaging. The plant extracts that can be used in sunscreen cosmetics have been introduced. The effective components in plant extracts include flavonoids, phenylpropanoids, polyphenols and carotenoids which contain the benzene ring or conjugated structure. The article elaborates on them in detail, hoping to contribute to the development of natural sunscreen cosmetics. 数据和表 | 参考文献 | 相关文章 | 计量指标

First, amphiphilic TiO2 nanoparticles were prepared and then an O/W Pickering emulsion stabilized by these nanoparticles was successfully used to prepare the microspheres. The results of UV transmittance, light stability, in vitro transdermal and sensory tests showed that, the microspheres could improve the ability of UV protection and the light stability of avobenzone, and reduce the transdermal absorption of AVB. Moreover, the microsphere powder was delicate and easy to be washed away, and it could improve the whitening effect of TiO2. This structure made TiO2 nanoparticles evenly distributed and avoided direct contact between TiO2 and AVB; the nano-TiO2 on the surface of microspheres could filter a part of UV, so the service life of AVB in the microsphere could be prolonged. 数据和表 | 参考文献 | 相关文章 | 计量指标

The content of mercaptoacetic acid in these products and the pH values thereof were determined according to “Safety and Technical Standards for Cosmetics” （2015 edition）. The testing results of content of mercaptoacetic acid were compared with the claims on the approved formulas and labels of products. The purpose of the survey was to gather information about the production and quality of the perm cosmetics on domestic market, and to uncover the safety risk and provide supervision suggestions. The results showed that 97 batches of unqualified samples were found, indicative of a disqualification rate of 18.73%. The measured values of mercaptoacetic acid were all within the limits. However, 66 batches of unqualified samples were ascribed to the inconsistency between the testing results and those claimed on the approved formulas and labels. The pH value of 1 batch failed to meet the standard, and 31 batches of unqualified samples were simply ascribed to problematic labeling or approved formulas. According to the results, a multi-dimensional comparison and in-depth analysis of the measured values of key indicators were carried out. In view of so many problems existing in the market of perm cosmetics, special sampling inspections should be strengthened in such cosmetic concentrated field, in which checking of non-standard labeling or approval documents should be strengthened, so as to achieve market standardization as soon as possible. 数据和表 | 参考文献 | 相关文章 | 计量指标
