Description

Blue-light-resistant and infrared-resistant composition and application thereof

Technical Field

The invention relates to the field of cosmetics, and mainly relates to a blue light-resistant and infrared-resistant composition and application thereof.

Background

Blue light, one of the urban light pollutions, has become two major light pollutions which affect the skin most with ultraviolet light. Our daily use of computers produces blue light, with 8 hours of blue light exposure corresponding to 1 hour of sun exposure.

The blue light is a light existing all the time in the nature and also an important component of sunlight, and with the development of scientific technology, the blue light has increasingly serious harm to the skin and eyes of people in light sources such as mobile phones, computers, projectors, LED table lamps, automobile headlights and the like which are in daily contact with people. High energy short wave blue light can cause eye diseases of different degrees, such as asthenopia, visual deterioration, cataract, AMD, and even blindness. High-energy short-wave blue light at night can inhibit melatonin secretion, so that biological clock disorder is caused, and various diseases of the body are caused. The long-term exposure of the human body to blue light not only causes visual fatigue and premature eye failure, but also generates oxidative stress and increases skin photodamage. If permanently exposed to electronic devices such as cell phones, tablets and computers, fluorescent bulbs and LED light sources just before sleep, sleep disorders, melatonin malfunction and premature eye failure will result. Just as with uv protection, it is also necessary to protect the skin from the hazards of blue light, which can help alleviate premature aging of the skin. In addition, the damage of infrared rays to the skin is not paid enough attention, the penetrating power of heat radiation caused by the infrared rays to the skin is stronger than that of ultraviolet rays, the damage of the ultraviolet rays can be enhanced, and when the skin is irradiated by the ultraviolet rays and the infrared rays, erythema is more easily generated, and water in the skin is correspondingly lost.

In addition, as the climate becomes warm and the ozone layer is destroyed, the exposure opportunities of visible blue light (400-. In the technical specification for cosmetic safety (2015 edition), 27 standard sunscreens are specified, wherein 25 organic sunscreens and 2 inorganic sunscreens are provided, but the organic sunscreens and the inorganic sunscreens are artificially synthesized chemical sunscreen structures, and the ingredients can only protect ultraviolet rays in a UVB band and a UVA band generally and do not relate to protection of a near infrared band and a visible blue band. When a wider band of protection is required, especially near infrared and blue bands, only the 27 sunscreens prescribed by the state are not sufficient. CN105434188A provides a sunscreen cream and a preparation method thereof, wherein the sunscreen cream comprises the following components: physical sunscreen agents, based on the total weight of the sunscreen cream: 2 to 10 percent; preferably 5 to 10%; chemical sunscreen agents: 2 to 30 percent; preferably 15 to 25%; antioxidant: 0.01-1%; preferably 0.1-0.8%; grease: 5.5 to 20 percent; preferably 10-20%; emulsifier: 2 to 6 percent; preferably 4 to 6%; humectant: 3 to 15 percent; preferably 8 to 15%; carnosine: 0.1-2%; preferably 0.1 to 1.5%; water: 10 to 85 percent; preferably 22-53%. The sunscreen cream provided by the invention can protect the harm of infrared rays to human tissues. However, the above prior art can only protect infrared rays and cannot resist the damage of blue light to the skin.

In conclusion, the composition capable of resisting blue light and infrared rays is provided and applied to cosmetics, and has wide application prospect and great market value for repairing and protecting the skin damaged by light.
