As a calorie-free, high-intensity sweetener, Acesulfame K ( FDA 21 CFR§172.800 ) is an 80's developed non-nutritive additive with good sensory and physical properties. Features: Ace-K is about 200 times sweeter than sucrose in a five percent solution, and its taste is very much close to that of sucrose with a fast onset of sweetness and no unpleasant delay. Synergistic effects have also been found in mixtures of Ace-K and other sweeteners, e.g.aspartame or sorbitol, on either taste or sweetness. (e.g.Synergistic with aspartame 1:1, the sweetness is 300 times sweeter than that of sucrose.) Ace-K is quite stable under normal storage conditions, and no differences are found among samples newly produced or after up to five years' shelflife.

This is known as a powerful antioxidant similar in effect to the ever popular and patented Pycnogenol, but far less expensive. Grape seed extract is rich in polyphenols, a beneficial compound shown as being high in antioxidants that helps to improve circulation. People have been using grapes since ancient times not only for eating and drinking but for medicinal purposes as well. Different parts of the plant including the grapes themselves, the leaves, and the stems, have been used. It was not until the 1970’s when a French biochemist isolated from grape seed the substance called oligomeric proanthocyandin (OPC). This substance was said to improve blood circulation and to have some protective properties against heart disease. Experimental data does suggest that grape seed also has anti-inflammatory and anti-carcinogenic properties and prevents the formation of plaque in the arteries. All of this information is great for cardiovascular health, but there have been no findings to indicate that it can aid in weight loss or exercise.

Ursodeoxycholic Acid (UDCA) Ursodeoxycholic acid (UDCA), a hydrophilic bile acid, is known as a cytoprotective agent. UDCA prevents apoptosis induced by a variety of stress stimuli including cytotoxic bile acids such as deoxycholic acid (DCA). Here we examined the molecular mechanism by which UDCA can antagonize DCA-induced apoptosis in human colon cancer cells. UDCA pretreatment decreases the number of apoptotic cells caused by exposure to DCA and UDCA. Further studies of the signaling pathway showed that UDCA pretreatment suppressed DNA binding activity of activator protein-1 and this was accompanied by downregulation of both extracellular signal-regulated kinase (ERK) and Raf-1 kinase activities stimulated by exposure to DCA. DCA was also found to activate epidermal growth factor receptor (EGFR) activity and UDCA inhibited this. Collectively, these findings suggest that the inhibitory effect of UDCA in DCA-induced apoptosis is partly mediated by modulation of EGFR/Raf-1/ERK signaling.

Arbutin (Arbutin, Arbutosie, Ursin, Uresol) Arbutin Arbutin is the active substance originated from natural plant which can whiten and lighten skin. It can infiltrate into the skin quickly without affecting the concentration of cell multiplication and effectively prevent activity of tyrosinase in the skin and the forming of melanin. By combined arbutin with tyrosinase, decomposition and drainage of melanin are accelerated, splash and fleck can be got ride of and no side effects are caused. It is one of the safest and most efficient whitening materials that are popular at present. It is also the most competitive whitening activity in the 21st century. Arbutin synthesized by our company owns high purity and excellent quality. Almost no hydroquinone can be examined. It is the only arbutin product that can meet this high standard.

Reishi Mushroom Extracts Red Reishi (Ganoderma Lucidum), commonly known as Ling Zhi in Chinese, is a herbal mushroom known to have miraculous health benefits. It has been used in Japan and China for over 2,000 years and thus making it the oldest mushroom known to have been used as medicine. Since ancient times, the Reishi mushroom was reserved for emperors and royalties. It has been revered as nature’s rarest and most beneficial herb. In the Superior category of Shen Nung Ben Cao Jing, the oldest and most famous medical text on Oriental herbal medicine, red Reishi is ranked as the number one herb, ahead of ginseng, because of its following qualities: 1. It is non-toxic and can be taken daily without producing any side effects. 2. When it is taken regularly, it can restore the body to its natural state, enabling all organs to function normally. 3. Immune modulator - regulates and fine tunes the immune system. What are the benefits of Reishi? Red Reishi is primarily composed of complex carbohydrates called water-soluble polysaccharides, triterpeniods, proteins and amino acids. Researchers have identified that water-soluble polysaccharides are the most active element found in Red Reishi that have anti-tumour, immune modulating and blood pressure lowering effects. Another major active ingredient found in Red Reishi are triterpenes , called ganoderic acids. Preliminary studies indicated that ganoderic acids help alleviate common allergies by inhibiting histamine release, improve oxygen utilization and improve liver functions. Triterpenes are bitter in taste and the level of the triterpene content contained in a product can be determined by the bitterness. Regular consumption of red Reishi can enhance our body’s immune system and improve blood circulation, thus improving better health conditions. Generally, Reishi is recommended as an immune modulator and a general tonic. Red Reishi is also used to help treat anxiety, high blood pressure, hepatitis, bronchitis, insomnia, and asthma.

It is preferably used with low TDI free polyurethane prepolymers. It provides excellent mechanical properties with low heat build-up under regular high compression loads, superior hydrolytic resistance up to temperatures of 150°C (300°F), low wear and tear, and can be processed easily with ribbon-flow technology. M-CDEA has been approved in Europe for polyurethane coatings used in contact with food.
