  • the invention relates to the field of cosmetics, in particular to a plant compound extract and application thereof in preparing sunscreen lotion.
  • Sunscreen the main functional ingredient for sunscreen function is sunscreen. It is mainly used to prevent skin sensitive people from producing sun dermatitis under direct sunlight, sunburn and absorb B-zone ultraviolet rays (280-320 nm). They usually have the following two problems: First, their UV absorption effect is not ideal, and second, there are problems in safety, prone to pore clogging and allergies. In the past 20 years, with the destruction of the ozone layer, the global ozone crisis has led to an increase in the incidence of skin cancer. Scientific research has found that the ultraviolet energy (320-400nm) in zone A reaches 98% of the total energy of ultraviolet light, and the penetration of clothing, water and human skin is stronger than that of zone B.
  • Zone A and Zone B The UV superposition in Zone A and Zone B is far more harmful to the human body than the UV damage in Zone B. It can lead to accelerated deposition of melanin in the skin, long-term effects, which can cause irreparable skin damage, and can also lead to skin cancer or death. At present, consumers are increasingly demanding sunscreen health care, and there is an urgent need for a sunscreen that is both efficient and safe, and can simultaneously cover the ultraviolet rays in Zone A and Zone B.

植物复配提取物、制备方法及其应用
相关申请的交叉引用
本申请要求于2017年07月13日提交中国专利局的申请号为CN201710570350.5、名称为“植物复配提取物、制备方法及其应用”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及化妆品领域,特别是涉及一种植物复配提取物及其在制备防晒乳中的应用。
背景技术
防晒霜,其发挥防晒功能的主要功效成分为防晒剂。主要是用于防止皮肤敏感者在日光直接照射下产生日光皮炎,晒斑及吸收B区紫外线(280-320nm)。它们通常存在下面两个问题,一是其紫外线吸收效果并不理想,二是在安全方面存在着问题,易发生毛孔堵塞和过敏。近20年来,随着臭氧层破坏,全球性臭氧危机导致皮癌发生率增长。科学研究发现:A区紫外线(320-400nm)到达人体的能量占紫外线总能量的98%,对衣物、水、人体皮肤的穿透力也比B区更强。A、B区紫外线叠加对人体伤害远大于B区紫外线伤害。会导致皮肤黑色素加速沉积,长期作用,会造成不可治愈的皮肤损害,严重的还可导致皮癌或致死。目前消费者对于防晒保健的要求越来越高,迫切需要有一种既高效又安全,能同时覆盖A区及B区紫外线的防晒剂。
目前防晒产品添加的防晒剂分为化学防晒剂和物理防晒剂。化学防晒剂主要是甲氧基肉桂酸辛酯、丁基甲氧基二苯甲酰基甲烷等,其主要为吸收B区紫外线,物理防晒剂如二氧化钛、氧化锌主要为阻隔和反射可见光,但二氧化钛、氧化锌会造成毛孔堵塞和过敏。
