NS Natural Soluble Yeast Beta-Glucan

Since the 21st century, scientists have found that the role of polysaccharide in organisms is becoming increasingly important, and that in some respects even exceeds the role of protein, especially in the field of biomedicine. β-glucan takes an extremely essential position, for it is a polysaccharide widely found in bacteria, fungi and higher plants with a stable structure and strong biological activity. In view of sources, it can be divided into yeast glucan, oat glucan, hulless barley glucan, ganoderma champignon glucan, etc. The biological activity of yeast glucan is far superior to the glucan activity of lentinan, Flammulina velutipes Polysaccharide (FVP), krestin (the immune defense system against yeast has been established during human evolution, and CR3 receptors bound to yeast glucan exist on congenital immune cells). The functions of β-glucan in regulating human immunity, anti-tumor, anti-radiation, anti-inflammation, promoting injury recovery, lowering blood fat and blood glucose, anti-aging, etc., have been gradually discovered, catching a widespread concern in the world. In recent years, β-glucan has been widely used in the fields of medicine, food, and personal care products.

Yeast is relatively early applied by people, and is the most widely- used microbe. People often produce a variety of fermented food and wine by the use of its fermentation. Meanwhile, yeast is also a multi-biological therapeutic drug, which is included in the monograph(the German statutory herbal pharmacopoeia) written by the German Commission E as an antibacterial and anti-inflammatory herb that treats acnes. The β-glucan in the yeast wall is a key substance for yeast to exert its antibacterial and anti-inflammatory effects.

Yeast glucan is a 1-3, 1-6 linked glucose polysaccharide, which is only present in the yeast cell wall, while the β-(1,3)-(1,6) bond is distributed in a certain proportion. This structure makes it extremely difficult to dissolve in water. The introduction of special chemical radical groups through chemical modification has been a common means to increase water-insoluble macromolecule polymer. The chemical modification process is cumbersome and requires a large amount of organic solvent, and the product is relatively low in safety and environmental friendliness. Moreover, during the improvement of the water solubility of products, the carboxy methylation of yeast β-1,3-D-glucan also has an effect on the three-dimensional structure and biological function of molecules. If the carboxy methylation degree exceeds 75%, molecules will begin losing biological functions, and the complete replacement for the yeast β-1,3-D-glucan molecule will result in a complete loss of its biological efficacy.

The water-soluble natural glucan developed by molecular chaperones technology solves the disadvantage of chemically modified yeast glucan. Not only does this settle the problem of glucan solubility, but  also it fully retains the three-dimensional structure and biological activity. In this way, it can be easily used as carboxymethyl glucan and oat glucan, yet with higher biological activity.

Mechanism of Yeast β-Glucan

Combination of Yeast Glucan with a CR3 Receptor on the Surface of a Natural Immune Cell

Diagram of the biological activity of yeast glucan

Skin is a very important defense system for humans. It is a natural barrier between human bodies and the outside world, which also has metabolic and immune response functions. In the epidermis, the immune system of skin includes plasma cells, Langerhans cells, and keratinocytes. In recent years, Langerhans cells have been confirmed to have a very special relationship with macrophages in the skin, and play an extremely important role in skin immunity. There are many immune networks composed of Langerhans cells under the stratum corneum of the skin. Langerhans cells are dendritic cells, and their antennae can reach the stratum corneum cells, where the receptor CR3 of yeast β-glucan lives. The binding of glucan to the receptor causes a series of stereo chemical changes that activate macrophages and produce various cytokines (e.g., IL-1, IL-6, GM-CSF), epidermal growth factor (EGF), tumor necrosis factor(TNF-α) and angiogenic factor (AF),etc.. On aging or wrinkled skin, an increase in epidermal growth factor can promote the production of collagen and elastin, thus improving the exterior of skin and eliminating small wrinkles.

Studies have also shown that UV radiation has an inhibitory effect on Langerhans cells in the skin. If the skin is exposed to the sun for a long time, the number and activity of Langerhans cells will be greatly reduced, and the defense immunity of skin will be weakened. In addition to its own sunscreen effect and the ability to relieve pain and inflammation, β-glucan can also promote the proliferation of Langerhans cells and enhance skin immunity. Clinical studies have also shown that yeast glucan plays a role in anti-inflammation, anti-allergy, eliminating the activity of radicals, moisturizing and accelerating the renewal of the stratum corneum, helping the skin resist external exogenous various mechanical and chemical stimuli and promoting the recovery of injuries. Experiments have proved that yeast glucan can significantly reduce the skin allergic inflammation caused by stimulating active ingredients such as fruit acids.

Application of yeast β-glucan in cosmetics

The water-soluble natural β-glucan is derived from natural raw materials and is non-toxic and non-irritating. Adding β-Glucan solution to cosmetics can relieve reduce irritation, renew and repair stressed skin, effectively reduce skin wrinkles, improve skin moisture retention and smoothness, promote the recovery and regeneration of scars, brighten the skin, and treat specific dermatitis. It is widely used in anti-wrinkle and anti-aging products, sunscreen and after-sun care products, soothing products for sensitive skin and other high-end cosmetics.

NanoActive Repair

Nanoactive Repair is a novel ceramide nanoliposome preparation (NanoLiposomal Repair).
Product Name: Nano Liposomal Ceramide; Nanoactive Ceramide; BioaActive Ceramide; Soluble Ceramide; Nanoactive Repair; Bioa Active Repair; SymRepair 100 CAS: 100403-19-8

Description: The results of skin research indicate thatceramide is the main component of the skin’s stratum corneum lipids, accounting for about 50% of the epidermal keratinous lipid content. It plays a key role in the physiological function of the stratum corneum and takes on the role of skin protection, moisturizing and nourishing. The application of a skincare product containing ceramide for external use can achieve the purpose of preventing allergic skin diseases and the effect of suppressing melanin brown spots. The ceramide-3 with the same structure as natural ceramide is used as the raw material. The nano-ceramides, developed with the nano-transmission system (NDS), has a particle size of less than 30nm, which solves the problems of solubility and irritation, so that it is stably encapsulated in nano-carriers to synergize with natural stratum corneum components of skin, such as phospholipids, cholesterol and stearic acid to repair the barrier.

Ceramide-3 structure


The main role of ceramide in the stratum corneum of the epidermis:

  • Barrier: As long as the ceramide is removed from the epidermis, the barrier function of the skin disappears.
  • Adhesion: Ceramide can significantly enhance the adhesion between keratinocytes, improve skin dryness and reduce skin desquamation.
  • Moisturizing: Ceramide has a strong ability to associate water molecules, maintaining the moisture of the skin by forming a network in the stratum corneum.
  • Anti-aging: Ceramide can improve skin dryness, desquamation, roughness and tarnishing, increase skin thickness, improve skin moisturizing ability, reduce wrinkles, increase skin elasticity and delay skin aging.
  • Anti-allergy: Ceramide can help the stratum corneum thicken significantly, improve the skin’s tolerance, inhibit the invasion of harmful substances from the outside, avoid the sensitivity of skin caused by the invasion, and have the effect of restoring couperose skin.
  • However, many skin conditions can cause a decrease in ceramide levels leading to impaired skin barrier (more than 50% reduction in total ceramide or single ceramide):

  • Aging
  • Allergic dermatitis
  • Dry skin / dry skin in winter
  • Dandruff
  • Psychological stress
  • Gender (older women versus older men)
  • Race/skin type
  • Ceramide is the most important component of the lipid barrier of the skin, and ceramide can repair the skin barrier function. However, it is difficult to extract natural ceramides, to synthesize natural ceramides, to formulate natural or natural ceramides with high melting point (over 90 C), and to crystallize low concentration, ineffective and high concentration products, which limit the use of ceramides. A new type of synthetic ceramide developed similar to the natural ceramide structure is used as the raw material, and the nano-ceramides with a particle size of less than 30 nm developed by the nano-transport system (NDS) have solved the problem of solubility and applicability. It is stably encapsulated in a nanocarrier to synergize with skin natural stratum corneum components such as phospholipids, cholesterol and stearic acid to repair the barrier.
