However, both physical sunscreens and chemical sunscreens have their own disadvantages. For example, physical sunscreens have a dry skin feel and are prone to stagnation when applied
However, chemical sunscreens generally have a sticky skin feel, and are restricted substances in cosmetics, with strict restrictions on the amount of use. How to develop a product that maintains a high sun protection value while maintaining a good skin feel has become a challenge in the industry. big problem

Abstract
The invention provides a sunscreen composition and a preparation method thereof, and belongs to the field of cosmetics. In the sunscreen composition provided by the invention, a sunscreen agent A containing acicular titanium dioxide and a sunscreen agent B containing spherical titanium dioxide are used in combination, so that synergistic ultraviolet radiation B (UVB) and infrared radiation A (IR-A) resistance effects can be achieved; zinc oxide is added, so that the sunscreen composition has the effect of resisting ultraviolet radiation A (UVA) damage; and argania spinosa kernel oil, tocopherol acetate and dragosantol synergistically take an effect to resist oxidation and resist inflammation as well as increase sunscreen values, thereby reducing influence caused by excessively much addition of sunscreen agents on skin sense and stability. The sunscreen composition provided by the invention realizes resistance effects to whole-band radiation which is harmful to the skin in the daily sunlight; and moreover, the sunscreen agents contained in the sunscreen composition are high in transparency, so that the sunscreen composition is conducive to compound use with other cosmetic raw materials.
Description
technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen composition and a preparation method thereof. Background technique [0002] Protecting the skin from the damaging effects of UVA and UVB rays with broad-spectrum sunscreens is now a generally accepted approach to protecting the skin from the harmful effects of the sun, such as skin cancer and premature aging. However, more than half of the solar energy received by the skin is visible light and infrared radiation, and the damage they cause to the skin cannot be ignored. For example, the damage of visible light to the skin is mainly the generation of free radicals and pigmentation; the penetration of near-infrared IR-A on the skin Exceeding ultraviolet rays, the skin can generate free radicals, reduce the skin's ability to resist oxidative stress, and at the same time cause biological damage to the skin, such as destroying collagen fibers. The process of ...
