An insight into pharmaceutical solvents and how they are utilized in various pharmaceutical applications
Pharmaceutical Solvents are specialized solvents used in numerous
pharmaceutical products. The majority of these solvents include propylene
glycol, glycerin, isopropyl alcohol, and polyethylene glycol. These solvents
offer several advantages over the traditional solvents that have been used for
decades. One of the primary advantages is that these solvents are less toxic
and cause less environmental contamination. There are various applications of
pharmaceutical solvents including cleaning, drying, sterilization, lubrication,
filling, unrolling, wrapping, and shipping. Pharmaceutical industries utilize
solvents in various forms like gels, fluids, aerosols, solutions, effervescent
and injectable solutions, injectables, shelf-life, etc.
Biotechnological applications of solvents are expected to grow
faster than the other areas of the pharmaceutical industry. Several companies
have developed synthetic biocides and ethanolamines that can replace hazardous
drugs in hazardous waste management. These solvents are anticipated to be more
cost-effective than VOCs. Several companies are researching the development of
pharmaceutical formulations containing glycerol, which is an alcohol-based
alternative to ethanol. In the field of cosmetics, several companies are
exploring the development of pharmaceutical
solvents for the removal of contaminants from cosmetics. Many
pharmaceutical companies are exploring the development of liposomes, which are
small-molecule substances that can penetrate into the fat layers.
One challenge will be to remove these liposome molecules from fat
without damaging the rest of the body. Another challenge will be to create a
formula that can remove contaminants from small and large samples without
causing a chemical imbalance. Other challenges include the introduction of
microorganisms and the concentration of these organisms in aqueous solutions.
The concentration of microorganisms is high in the anoxic environment of East
Asia. The atomic solute concentration is much lower in other regions, including
the US and Europe. The solvent development companies are examining several
chemical formulations to address this issue. Many companies in Singapore,
Japan, and the U.S. are continuing their R&D activities in the field of
pharmaceutical solvents. For instance, recently, a U.S.-based company launched
a new greener, dipolar aprotic solvent made from renewable cellulose sources.
