Abstract

The invention discloses a coix seed whitening sunscreen and a preparation method thereof, which is composed of the following raw materials in parts by weight: 20-35 parts of barley extract, 0.2-0.6 part of North American witch hazel extract, 5-20 parts of arbutin, 0.05‑0.15 parts butanediol, 1‑10 parts cactus extract, 0.1‑0.4 parts citric acid, 60‑80 parts deionized water, 3‑6 parts dipotassium glycyrrhizinate, 0.1‑0.3 parts sodium hyaluronate, 0.5 parts ‑1.5 parts of ultraviolet absorber, the ultraviolet absorber is one or more of ultrafine titanium dioxide powder and ultrafine zinc oxide. The coix seed whitening sunscreen of the invention has mild performance, no irritation to the skin, and can play comprehensive protective functions of whitening, ultraviolet resistance and anti-inflammation under the premise of safety and harmlessness.

Description

technical field [0001] The invention belongs to the technical field of sunscreen products, in particular to a coix seed whitening sunscreen and a preparation method thereof. Background technique [0002] The harm of ultraviolet rays to the human body is far greater than the beneficial effect. According to different wavelengths, ultraviolet rays can be divided into three segments, namely UVA, UVB and UVC. UVC can be absorbed almost completely and cannot reach the ground; Melanosis; a large part of UVB is absorbed by the epidermis of the skin, which can cause strong photodamage to the skin. The dermal blood vessels in the irradiated area expand, and the skin may appear redness, swelling, blisters and other symptoms. Long-term exposure to the skin will cause erythema, inflammation, and skin aging. Severe cases can cause skin cancer. Coupled with the influence of environmental pollution, staying up all night, computer radiation, etc., people's skin condition is getting worse a...
