I need to mercury and chemical materials

one of my pharmaceuticals manufacturer need L-tartaric acid B.P, USP Grade, for pharma use if you are manufacturer please send us its 500gm sample, and also its COA, MSDS with it, we further need to how much minimum quantity do you ship to us

Therefore, please state your specifications and terms

I need tartaric acid L grade technical

Characters: Ivory or straw yellow powder or granular solid which is easily soluble in hot water. It is a non-ionic emulsifier with HLB value of 8-10. Applications: It can produce strong effects such as emulsification, dispersing and aging resistance, so it can be used as good emulsifier and dispersant. (1) It can increase the springiness, toughness and gas-holding capability of dough effectively, reduce its softening degree, increase volume of bread and steam bread, and improve their organization and structure. (2) It can react with amylose to delay and prevent the food aging. (3) It can be used in cream to make it smoother and finer. (4) It can be used in butter and concentrated butter to prevent oil separating and enhance its stability. (5) It can also be sued in sugar, syrup and spices. (6) It can be used in non-dairy creamer to make the emulsion homogeneous , stable and supple in mouth. Usage: (1) Put this product in warm water at about 60℃ to get paste shaped substance, and then use it in appropriate proportion.

Recommended Addition Amount: Addition maximum is 1.0% for raw dried flour products and raw wet products, while 5.0% for non-dairy creamers. The addition amount can be changed based on production need for cream and fermented milk.
