Polysaccharide raw materials lead biological skin care

The rapid development and wide application of modern science and technology have brought brand new development opportunities to the cosmetics industry. The research and development of cosmetics has experienced chemical beauty, plant beauty, and is moving towards the goal of biological beauty and genetic beauty.

Polysaccharides are important bioactive macromolecules and important components of the dermal layer of human skin. Many polysaccharides have prominent regulatory effects in the skin metabolism process. The application of bioactive polysaccharides as functional cosmetic additives in cosmetics can produce moisturizing, Promote the proliferation of epithelial fibroblasts and other functions, and inject new vitality into the development of cosmetics.


What is polysaccharide

Sugar is the most widespread type of organic matter in nature. From the structural point of view, sugars are polyhydroxy aldehydes or polyhydroxy ketones, and a class of organic compounds that can generate polyhydroxy aldehydes or polyhydroxy ketones after hydrolysis.

Polysaccharides are a relatively complex type of natural active ingredients. Some of them have obvious functions to improve human immune function, some have obvious effects on anti-aging skin, and some have very strong anti-inflammatory and antibacterial properties, but they all It has very significant moisturizing properties and certain nutritional properties. It is not surprising that natural active substances such as polysaccharides and their derivatives are used as beauty cosmetics. Because it is a natural product, it comes from natural products that are familiar or commonly used by consumers. Food and Chinese herbal medicine, its safety is easily accepted by consumers, it is a very promising natural active substance in cosmetics. With the application of high-tech methods, more and more natural active substances of sugars will be used in beauty cosmetics in the future.

Polysaccharides are formed by the condensation and loss of water from multiple monosaccharide molecules. They are a type of sugar substance with complex and huge molecular structures. The general formula is (C6H12O6)x. Polysaccharide (polysaccharide) All carbohydrates and their derivatives that conform to the concept of polymer compounds are called polysaccharides. There are glucose, mannan, galactan, etc. which are composed of one type of monosaccharide (usually the word an is added to the English monosaccharide stem), and heteropolysaccharides composed of two or more monosaccharides ( Hetero polysaccharide), glucosamine dextran containing amino sugars, etc., are actually diverse in chemical structure.

In terms of molecular weight, there are polysaccharides ranging from 5,000 molecules to more than 106 polysaccharides. A polysaccharide is a polysaccharide composed of at least more than 10 monosaccharides of sugar chains combined with glycosidic bonds.


Classification of polysaccharides

According to the raw material source of polysaccharides, it can be divided into five categories: plant polysaccharides, animal polysaccharides, edible fungus polysaccharides, microbial polysaccharides and marine biological polysaccharides.


The role of polysaccharides in cosmetics

Common polysaccharide raw materials in cosmetics


Hyaluronic acid

Hyaluronic acid (HA, commonly known as sodium hyaluronate or hyaluronic acid) is a biomedical material that is naturally degradable and absorbable. It is widely distributed in animal and human tissues and extracellular matrix, and has a high content in eye vitreous, aqueous humor, synovial fluid, skin and umbilical cord. Commercial hyaluronic acid is generally its sodium salt, namely Sodium Hyaluronate, which is still called hyaluronic acid in custom. Hyaluronic acid has a wide range of uses. After further processing, its stability can be improved, and it can be used in the fields of beauty, skin care and medicine. The medical field is mainly used in ophthalmology, orthopedics and medical plastic surgery. Hyaluronic acid used for medical plastic surgery is an implanted device, which has a higher risk and belongs to the third category of medical devices.

Hyaluronic acid is actually the condensation of two glucose derivatives, and then repeating this structure, it becomes hyaluronic acid, which is also very close to the structure of most polysaccharides. It is because of this structure that most polysaccharides are Some functions-moisturizing.


Chitin and its derivatives

Chitin polysaccharide derivative is a highly safe and non-irritating skin conditioner. It is highly moisturizing, can form a film on the skin surface to breathe, complex heavy metals, effectively remove toxins entering the skin, and clean the skin. Smooth and delicate effect.


Cellulose Sulfate

Cellulose sulfate has some excellent physical and chemical properties: ①good biocompatibility, ②suspension stability and unique emulsification effect, can act as a stabilizer in cosmetics; ③have the function of moisture absorption and water retention, in cosmetics Can play an emollient effect.


heparin

Heparin has a repairing effect on scars and can effectively promote the proliferation of local vascular endothelial cells in the wound. It can improve microcirculation, restore or increase local blood circulation, open and regulate skin color, and has anti-inflammatory and moisturizing effects.
