Commodity: Dicalcium phosphate Feed Grade Use DCP is the feed preparation of raw materials, Animal right to supplement calcium needs. Coarse its products more applicable to the preparation hens, ducks feed, concentrate feed and premix. Product Nature Molecular Formula:CaHPO4·2H2O,Molecular weight:172.09,After drying with loose white powdery crystals or granules. Neutral products, the melting acid, water-soluble, hygroscopicity small, heated to 90 around gradually lose water of crystallization. Product Features The purity of the product, calcium and phosphorus ratio appropriate to ensure a higher degree of its biological effects. Phosphorus content greater than 18% of the products, due to a small amount of MCP, and its biological effects better. This unique high-tech companies use technology to make our products crystallization, high purity and its harmful impurities significantly below standards:HG26362000 Drying process advanced products, products with low free water under the premise that the product does not lose crystallization of water, avoid the product in the drying process for the loss of water caused by crystallization of biological effects of the reduction. Coarse particle DCP in the animals stay in the stomach longer and more conducive to the absorption of calcium phosphate, the product of Micro-particle DCP granulation from mechanical, without any chemical binder.

Product Name: Oligopeptide-10 INCI Name: OLIGOPEPTIDE-10 Molecular Formula: C78H140N20O15 Molecular Weight: 1598.07 Appearance: White powder Purity: 99% CAS Number: 466691-40-7 Standard: Enterprise Standard Supplier: ZhenYiBio Oligopeptide-10 (oligopeptide-10)-is an antibacterial peptide used to treat acne symptoms. Research data showed that the peptide showed excellent activity against P-acne bacteria alone, but it was found to be more effective in combination with low levels of salicylic acid. Salicylic acid can open the pores to allow oxygen to enter, while allowing oligopeptide-10 to enter the pores for maximum performance without irritation. The 0.5% combination of oligopeptide 10 and 0.5% salicylic acid showed a 40% reduction in acne, irritation, pustules and papules after 28 days.
