9005-38-3 - Nature

White or light yellow powder, almost odorless, tasteless. Soluble in water to form a viscous liquid, insoluble in ethanol, ether, chloroform and acid (pH <3). It is hygroscopic, and the pH value of 1% of the water is 6 to 8. The viscosity of aqueous solution is stable at pH 6 ~ 9, and gelling can be formed in the presence of high-priced ions such as Ca2+. It is compatible with hydroxycellulose, protein, sugar, starch and most water-soluble gums.

9005 - 38 - 3 - Inspection

Clarity and Color of Solution

• Take 0.10 g of this product, add an appropriate amount of water and stir continuously until dissolved, dilute with water to 30 ml, shake well, and let stand for 1 hour. Accurately measure 1.0 ml, place it in a 10 - ml volumetric flask, dilute with water to the mark, shake well, and inspect according to the law (General Rule 0901 and General Rule 0902). The solution should be clear and colorless. If it is turbid, when compared with Turbidity Standard Solution No. 2 (Method 1 of General Rule 0902), it should not be more turbid. If it shows color, when compared with Yellow Color Standard Solution No. 2 (Method 1 of General Rule 0901), it should not be darker.
