Description

Acrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130°F. Boiling point 286°F. Freezing point 53°F. Corrosive to metals and tissue. Prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize.;Acrylic acid, [waste] appears as a colorless liquid with a distinctive acrid odor. Combustible. Flash point 130°F.

Case Study

Preparation of Carbomer 940-Based Hydrogel for Wound Healing

Huang, Yingbei, et al. International journal of biological macromolecules, 2019, 132, 729-737.

Carbomer 940 (CBM940) has been widely used in the pharmaceutical and cosmetic industries due to its gel stability, bioadhesion, rheology and high patient acceptance. A hydrogel with wound healing ability (Bsp/CMC/CBM 940) can be simply prepared by physically mixing carbomer 940 (CBM940) with Bletilla striata polysaccharide (Bsp) and carboxymethyl chitosan (CMC).
Preparation procedure of carbomer 940-based hydrogel
· 0.5% (w/w) CBM940 was prepared by dissolving 0.5 g CBM940 in deionized distilled water, and the resultant solution was kept overnight at ambient temperature.
· CMC and Bsp solutions, each in a concentration of 10% (w/v), were then prepared. CMC and CBM940 solutions were afterwards mixed in three different concentrations (1:1, 1:2 and 2:1, respectively), and stirred for 5 minutes.
· After adjusting the pH to 7 with triethanolamine, Bsp solution (10%) was added. The entire solution was eventually adjusted to a concentration of 100 g by the addition of deionized distilled water, and was stirred regularly at 25°C for 20 min until a homogenous, transparent and well-gelled hydrogels were formed.
