Abstract

The invention discloses a high-content vitamin C and vitamin E stable system compound preparation. The high-content vitamin C and vitamin E stable system compound preparation comprises the following components in percentage by weight: 10.0-15.0 percent of vitamin C, 1.0-1.5 percent of vitamin E, 6.00-9.0 percent of butyrolactone, 10.0-24.0 percent of ethoxy diethylene glycol, 7.0-26.0 percent of butanediol, 2.5-3.75 percent of PEG-40 hydrogenated castor oil, 6.0-10.0 percent of propylene glycol, 2.5-3.75 percent of polyethylene glycol-8, 6.0-10.0 percent of glycerinum and 16.0-24.0 percent of N-methyl pyrrolidone. The invention also provides a preparation method of the compound preparation. Through an anhydrous system, the contact between vitamin C and vitamin E and oxygen and heavy metals is greatly reduced, vitamin E is protected by virtue of vitamin C, and in reverse, vitamin E can coordinately protect vitamin C; therefore, the compound preparation is good in skin touch and easy to absorb, can be widely applied to the fields of medicines, medical care products, and personal care products which have functions of whitening, skin brightening, antioxidation, line reduction, anti-aging and the like.

Description

technical field [0001] The invention belongs to the fields of medicine, chemical industry and personal care products, and relates to a high-content vitamin CE stable system compound preparation and a preparation method thereof. Background technique [0002] Vitamin C and vitamin E are the most well-known natural antioxidants. One is water-soluble and the other is oil-soluble. They are widely derived from foods such as fruits, vegetables and meat. Since its discovery, countless studies at home and abroad have confirmed that it not only plays an important role as a powerful antioxidant for external and internal use in the fields of medicine and food, but also can be widely used as a powerful antioxidant in the fields of functional skin care products and cosmetics. But its stability has been the focus of domestic and foreign researchers. [0003] As we all know, vitamin C is difficult to maintain stability. Chemically speaking, vitamin C is a monovalent hydrophilic hydroxyl co...
