Hydrolyzed Sodium Hyaluronate is the sodium salt of hyaluronic acid, which is naturally present in the extracellular matrix of mammalian connective, epithelial and neural tissues and the corneal endothelium. In terms of chemical structure, sodium hyaluronate is also a long-chain polymer of glycosaminoglycan and Na-glucuronic acid-N-acetylglucosamine disaccharide units.
Sodium hyaluronate has significant moisturizing, lubricating, anti-aging and repair functions, and is widely used in all aspects of life, especially in beauty, skin care and health care. The molecular structure of sodium hyaluronate is formed by alternating arrangement of glucuronic acid and N-acetylglucosamine. It has strong water absorption capacity. Each molecule can absorb hundreds of times its own weight of water, which can significantly improve the skin's ability to lock in moisture and improve skin elasticity.
The benefits of sodium hyaluronate in cosmetics
In the field of beauty, skin care and cosmetics, due to its strong moisturizing ability, it is often added to creams, eye creams, essences, masks, etc. to help relieve dryness, tightness and fine lines, and keep the skin smooth and hydrated. Sodium hyaluronate is also widely used in the field of wound repair to help accelerate wound healing.
Moisturizing effect
Sodium hyaluronate has a higher moisture absorption at low relative humidity and a lower moisture absorption at high relative humidity. This unique property is adapted to the skin's requirements for cosmetic moisturizing in different seasons and different environmental humidity, such as dry winter and humid summer. The moisturizing property of sodium hyaluronate is related to its quality. The higher the quality, the better the moisturizing performance. Sodium hyaluronate is rarely used alone as a moisturizer and is often used in combination with other moisturizers.
Nutritional effect
Sodium hyaluronate is a biological substance inherent in the skin. Exogenous sodium hyaluronate is a supplement to endogenous sodium hyaluronate in the skin. Sodium hyaluronate with a smaller mass can penetrate into the epidermis of the skin, promote the supply of nutrients to the skin and the excretion of waste, thereby preventing skin aging and playing a role in beauty and skin care. Skin care is more important than other makeup and has become a modern people's awareness of beauty care.
Repair and prevention
Light burns or sunburns caused by sun exposure, such as redness, blackening, and peeling of the skin, are mainly caused by ultraviolet rays in the sun. Sodium hyaluronate can promote the regeneration of the skin in the injured area by promoting the proliferation and differentiation of epidermal cells and scavenging oxygen free radicals. It also has a certain preventive effect if used in advance. Its mechanism of action is different from that of the UV absorbers commonly used in sunscreens. Therefore, when mixed with UV absorbers in sunscreen skin care products, it has a synergistic effect, which can simultaneously reduce the penetration of ultraviolet rays and repair the skin damage caused by the small amount of ultraviolet rays that penetrate, playing a dual protective role.
The combination of sodium hyaluronate, EGF and heparin can accelerate the regeneration of epidermal cells, making the skin delicate, smooth and elastic. When the skin suffers from mild burns, applying aqueous cosmetics containing Hydrolyzed Sodium Hyaluronate on the surface can relieve pain and accelerate the healing of the skin in the injured area.
