Problems solved by technology

However, the problem with whitening raw materials is that they need to be stored away from light. Even if the packaging material of the product has been well protected from light, when we apply it on the skin, it will be exposed to visible light and radiation from electronic products. Affect its efficacy, and the final effect will be greatly reduced
In response to this problem, the products currently on the market will choose to add certain photoprotectants. However, these photoprotectants only have a protective effect on light within a certain wavelength range, and have no protective effect on the radiation of electronic products.

Abstract

The invention discloses whitening cream with the self-protection function and a preparation method thereof. The whitening cream comprises the following components in percentage by weight of 0.5-1% of bismuth subcarbonate, 0.5-1% of bismuth oxide, 1.5-2% of alpha-arbutin, 1-1.5% of nicotinamide, 2-2.8% of tranexamic acid, 1-5% of N-acetylglucose, 1.6-2.5% of beewax, 1.3-1.8% of a thickening agent, 7-15% of polyhydric alcohol, 0.2-0.5% of an antibacterial agent, 0.1-0.15% of essence, 0.2-0.5% of tocopheryl acetate, 2-2.7% of an emulsifier, grease, 2-3% of polydimethylsiloxane, 4-6% of cyclopentasiloxane, 0.03-0.08% of sodium hyaluronate, 0.7-1% of magnesium sulfate, 0.8-1.3% of wool fat, 0.3-0.7% of disteardimonium hectorite, 0.5-1% of ethanol, 3-4% of isononyl isononanoate, and the balance of deionized water. The bismuth subcarbonate and the bismuth oxide used in the invention can resist visible light with different wavelengths, have a good protection effect on the whitening raw material, and can effectively form a film on the skin surface to effectively resist blue light radiation caused by electronic products and the like to the skin.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, in particular to a whitening cream with self-protection function and a preparation method thereof. Background technique [0002] Consumers have higher and higher requirements for whitening products, hoping to achieve the ideal whitening effect in a short period of time. However, the problem with whitening raw materials is that they need to be stored away from light. Even if the packaging material of the product has been well protected from light, when we apply it on the skin, it will be exposed to visible light and radiation from electronic products. Affect its efficacy, and the final effect will be greatly reduced. How to make the whitening ingredients we add play its role to the maximum without being damaged by light is a problem that researchers have been working hard to solve. In response to this problem, the products currently on the market will choose to add certain photoprotectants. Ho...
