Embodiment 1

[0040] A polymer particle containing octyl methoxycinnamate (solvent violet 13 (CI60725) pigment), the raw materials used in the preparation process are calculated in parts by weight, and the composition and content of the raw materials are as follows:

[0041]

[0042] The concrete steps of its preparation process are as follows:

[0043] (1), at first, sodium lauryl sulfate and polyvinyl alcohol are dissolved in deionized water under room temperature, make it fully dissolve through stirring, obtain water phase;

[0044] (2) Mix solvent violet 13 (CI60725) pigment, octyl methoxycinnamate, methyl methacrylate, ethylene glycol dimethacrylate, cetyl alcohol, and azobisisobutylcyanide to obtain an oil phase ;

[0045] (3), in the homogenizer, control the rotational speed to be 13000-25000rpm, mix and homogenize the oil phase obtained in step (2) with the water phase obtained in step (1) for 15 minutes to obtain a homogeneous liquid;

[0046] (4), the homogeneous solution obt...

Abstract

The invention provides particulates containing methoxy cinnamate octyl. The particulate is prepared from that, by weight, 4-10 parts of methoxy cinnamate octyl, 0-0.3 part of CI60725 pigment, 4-10 parts of methyl methacrylate, 0.4-3 parts of two ethylene glycol methacrylate, 0.1-3 parts of two azo isobutyl cyanide, 0.1-0.5 part of polyving akohol, 0.1-0.5 part of hexadecyl alcohol and 0.1-0.5 partof lauryl sodium sulfate are added to 100 parts of deionized water. On the basis, the invention further provides a sunscreen composition of particulates containing methoxy cinnamate octyl and avobenzone, wherein the mass ratio of the particulates containing methoxy cinnamate octyl and the avobenzone is 1-10:1. The sunscreen composition solves the problem that the methoxy cinnamate octyl and the avobenzone cannot be combined, the photostability of the composition is obviously improved, at the same time, the stability of the avobenzone is also improved.

Description

technical field [0001] The invention belongs to the field of daily chemicals and relates to a sunscreen composition, in particular to a sunscreen composition containing octyl methoxycinnamate particles and avobenzone and its application. Background technique [0002] Consumers in today's society will become more and more mature in the colorful fashion, not only pursuing beauty, but also paying attention to health. When applying makeup, many women not only value the effect of makeup, but also hope that the use of makeup products will not affect their skin health, and even optimize their skin status. Among them, SPF protection is the most sought after in make-up. Sunscreens can effectively resist the harmful ultraviolet rays in the sun, prevent the skin from being tanned, and even cause sunburn or skin cancer. The market prospect of cosmetics with SPF protective function must be more and more broad, because the efficacy of cosmetics is not only a single beautification functi...
