How long does castor oil last?

How long does castor oil last?

Castor oil typically lasts for about 1-2 years, but exposure to heat, light, and air can further reduce shelf life. Different applications may have more or less tolerance for castor oil degradation. Lab Alley is proud to provide you with the highest quality castor oil whenever it’s time to restock.

Ethanol and activated carbon in the CBD/Hemp Industry

Ethanol and activated carbon in the CBD/Hemp Industry

Ethanol and activated carbon are two key materials in the CBD/hemp industry. Ethanol is a popular choice for hemp extraction, while activated carbon is used for purification and filtration. The chemical interaction between these two materials is important for the production of high-quality hemp extracts.

Ethanol precipitation for the purification of herbal medicines

Ethanol precipitation is a simple, efficient process that allows for the purification of traditional medicine herbal formulas. This technology operates on the principal that most bioactive compounds are increasingly soluble in higher ethanol concentrations, while compounds that are irrelevant or unsafe are usually less soluble. Increasing the ethanol concentration allows for impurities to precipitate out of solution while bioactive compounds remain. The result is a potent, bioactive concentrate that can be used to make tablets or granules in place of the less convenient, traditional decoction.

How and why Polysorbate 80 is used as a food additive

Polysorbate 80 is a low molecular weight, nonionic, amphiphilic compound. It is commonly used as an emulsifier in foods to improve texture, consistency, and mouthfeel of food products. Food grade polysorbate 80 may be used in bakery products to improve density, as a solubilizer in water-oil mixtures, and as a texture-enhancer in chocolate and ice cream.

Ethanol Use in Hand Sanitizers

Ethanol is an important ingredient in the manufacture of hand sanitizers, thanks to the ability of ethanol to act as a disinfectant. Ethanol concentration is perhaps the most critical parameter for ethanol-based hand sanitizers, with 60-95% ethanol being the most effective disinfectant. Higher concentrations of ethanol are actually less effective, since water is required for protein denaturation and to slow down evaporation. Ethanol-based hand sanitizers are more effective than alcohol-free sanitizers, and even offer many advantages over hand washing with regular detergents.
