Abstract

The invention belongs to the technical field of chemical and daily chemical products, and discloses a water-soluble sunscreen emulsion. The water-soluble sunscreen emulsion comprises a procyanidin extract, a sunscreen agent, an emulsifier, a preservative, a stabilizer and an auxiliary agent. The procyanidin extract is mainly prepared from blueberries, grape seeds and Chinese wolfberry fruits as the raw materials, and procyanidin has a strong absorption effect on ultraviolet (UV) at 280 nm and can inhibit the process that the ultraviolet rays directly irradiate the skin, so that the procyanidin improves the sunscreen effect of the sunscreen emulsion, and the SPF value of the sunscreen emulsion is as high as 45-60; in addition, the invention also discloses a preparation method of the sunscreen emulsion; and the surface of the procyanidin contains a large number of hydroxyl groups which can form hydrogen bonds with polar components in the emulsion and are stably combined in the sunscreen emulsion, and the hydroxyl groups have hydrophilicity and excellent water absorption and moisturizing performance, so that the sunscreen emulsion added with the procyanidin has relatively high water solubility and obvious moisturizing effect.

Description

technical field [0001] The invention belongs to the technical field of chemistry and daily chemical products, and relates to a water-soluble sunscreen emulsion and a preparation method thereof, in particular to a sunscreen emulsion containing proanthocyanidin extract and a preparation method thereof. Background technique [0002] Skin diseases caused by ultraviolet rays will continue to expand as people age. The short-term effects caused by ultraviolet radiation are mainly sunburn and tanning. After 2 to 24 hours of absorbing ultraviolet radiation, photoactive substances in the skin will produce erythema, accompanied by edema, blisters, peeling, and even systemic symptoms in severe cases. Exposure to the sun may cause various pigmentation spots, which can lead to skin cancer and other diseases in severe cases. Due to factors such as sun exposure and age, it can also cause skin aging phenomena such as dry skin, sagging, sagging and wrinkles. [0003] CN202010455788 disclose...
