Storage method

Food-grade plastic bag coated with kraft paper bag sealed packaging. Store in a cool, dry warehouse. Resistant to moisture, moisture and mildew.

Synthesis method

1. It can be extracted from the by-products of lactose production. After lactose is separated from the milk, the mother liquor first passes through a cation exchange resin column, and the eluate then passes through an anion exchange resin column. The eluate is collected and concentrated, left to stand to precipitate crystals, and filtered to obtain crude orotic acid.

Purpose

1. This product is a vitamin drug, suitable for hyperuricemia, hypercholesterolemia, chronic hepatitis and cirrhosis. It can also be used as an anti-anemia and nutritional fortifier. It has no side effects on the skin, is easily absorbed by the skin in W/O or O/W emulsion, and can promote the absorption of other active ingredients. Used in conjunction with vitamin A and vitamin B12, it can prevent skin pigmentation and has sun protection and anti-aging effects.

2.Orotic acid has no side effects on the skin and is easily absorbed by the skin in W/O or O/W emulsions. Sodium acid acid is absorbed more quickly and promotes the absorption of other active ingredients. It has the ability to significantly retain moisture and is particularly effective for dry skin. The amount added in moisturizers is 0.1% to 0.5%. Used in conjunction with vitamin A and vitamin B12, it can prevent skin pigmentation, sun protection and anti-aging. Use in nail polish to treat poor nail growth and prevent onychomycosis. Add conditioner to prevent hair loss.
