Abstract

The invention belongs to the technical field of cosmetics and discloses an anti-blue light composition as well as its preparation method and application. The composition comprises the following components in mass percentage: 0.1%-10% of surfactant, 0.1%-20% of polyhydric alcohol, and 0.1%-5% of oil. The composition has strong blue light absorption ability: the transmittance in the blue light band of 400nm to 500nm is significantly lower than the transmittance in the 500nm to 800nm ​​band, can block the damage of blue light to the skin, has a good blue light protection effect, and has an excellent anti-blue light effect; At the same time, the composition has no abnormality after being stored for one month in different environments (heat-resistant at 45°C, cold-resistant at -15°C, refrigerated at 5°C, room temperature), and has good stability.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to an anti-blue light composition and its preparation method and application. Background technique [0002] Visible light is the part of the electromagnetic spectrum that can be perceived by the human eye. For example, white light becomes red, orange, yellow, green, blue, indigo, and purple ribbons after being dispersed by a prism or grating, which is a visible continuous spectrum. Among them, the blue light band of 400-500nm The highest energy is called high-energy visible light. Blue light not only exists in sunlight and lighting, but also exists in a large amount in the background light source of digital products. With the deepening of research, people found that blue light can not only cause damage to the retina, but also cause certain damage to the skin, including oxidative stress, pigmentation, etc. Therefore, the impact of blue light on the human body has attra...
