Application of vitamins in cosmetics

Vitamins, also known as vitamins, are organic substances necessary for humans to maintain life. Vitamin content is very low in the human body, but it is indispensable. Vitamins play an important role in human body growth, development, maturity, metabolism and other stages. It can be said that vitamins are biologically active substances that maintain and regulate human body function metabolism.

In the cosmetics industry, because of its safety and efficacy, it is widely used. In the skin care, hair care and beauty products, all kinds of vitamins can be seen on the ingredient list.

The vitamins commonly used in cosmetics are A, B, c, E, H, K. In order to let everyone have a general understanding of the vitamins used in cosmetics, summarize several common vitamins and the problems facing them.

Common vitamins

Vitamin A and its derivatives

Retinol

Vitamin A is also known as retinol. Studies have shown that after using cosmetics containing vitamin A for 12 weeks, the skin's wrinkles are reduced, the pigmentation is reduced, and the skin's softness and smoothness are improved. Vitamin A can promote blood circulation and accelerate metabolism, so it can reduce pigmentation, and can repair damaged dermis, synthesize new collagen, increase skin elasticity, and slow down skin aging.

Retinol palmitate

Retinol palmitate is a derivative of vitamin A, an ester formed from retinol (vitamin A) and palmitic acid (a saturated fatty acid, the main component of palm oil). It is easily absorbed by the skin and then converted into retinol.

The role of retinol and retinyl palmitate has been reported in many reports, but irritation is still a challenge for cosmetic engineers.

Vitamin B and its derivatives

Vitamin B3 is also known as nicotinamide. Niacinamide accelerates metabolism, promotes the shedding of melanin-containing keratinocytes, acts on melanin that has been produced, reduces its transfer to surface cells, promotes the synthesis of epidermal proteins, and improves skin texture.

Vitamin B5, also known as pantothenic acid, is widely used in skin care and hair care products. Pantothenic acid is a vitamin necessary for hair growth and metabolism, so it is often added to hair care agents and hair conditioners. Experiments have shown that after continuous use of hair care products containing pantothenic acid, the hair will become smooth, strong and shiny.

Vitamin C and its derivatives

Ascorbic Acid (vitamin C)

Vitamin C, also known as ascorbic acid, can effectively reduce the activity of tyrosinase, thereby preventing the production of melanocytes, so vitamin C has a whitening effect. Vitamin C has high activity, but it is extremely unstable, and is easily damaged by light, heat, and oxygen to reduce its activity, and it is easy to dehydrate and change the structure in acidic solutions.

In order to improve the stability of vitamin C, modification of vitamin C, vitamin C derivatives such as 3-o-ethyl ascorbic acid, magnesium ascorbyl phosphate, ascorbic acid glucoside, ascorbyl palmitate, ascorbyl tetraisopalmitate, etc. It came into being. Vitamin C derivatives have outstanding effects in promoting skin regeneration, accelerating metabolism, whitening and anti-aging.

Vitamin E and its derivatives

Vitamin E

Vitamin E, also known as tocopherol, is a good antioxidant and free radical scavenger. Studies have confirmed that vitamin E has the following advantages: increase skin moisture content, improve moisturizing performance; improve skin smoothness; have a protective effect on uV irradiation.

In order to improve the stability of vitamin E, modification of vitamin E, tocopherol acetate, tocopherol phosphate sodium, tocopherol palmitate and other vitamin E came into being. In addition to the moisturizing effect of vitamin E derivatives, There are also potential anti-aging or help collagen and ELASTIN to rebuild properties, because it has cell signaling ability.

Problems needing attention in the use of vitamins and their derivatives in cosmetics

Vitamins are unstable;

Vitamin cosmetics should pay attention to antiseptic;

The production of vitamin cosmetics requires stable process conditions.

In short, vitamin raw materials are widely used in cosmetics. Cosmetic raw material manufacturers continuously improve the stability of raw materials through liposome and raw material modification. Cosmetic engineers need to constantly verify the stability of vitamin raw materials in different processes and raw material combinations during the research and development process. Sex and effectiveness.
