Product Polishing and Formulation

Consumerism is a preoccupation with buying consumer goods. Advances in science have led to an exponential rise in the number of products, gadgets, and formulations available to the consumer. Slick and polished advertising has been developed to convince us of our need for the latest and the best product. 

Polishing. This last process step prepares the product for final formulation or for actual sale. It is designed to remove any aggregated protein, remove residual chromatographic eluent(s), and place the product into a specific solvent. These requirements are admirably served by gel filtration. At this point, the sample volume is small and the product fraction to be applied is fairly clean. The gel and column equipment requirements are now within reason and, the clean samples result in much longer gel life. 

Nitrogen and other compressed gases such as carbon dioxide and nitrous oxide are used as propellants for topical pharmaceutical aerosols. They are also used in other aerosol products that work satisfactorily with the coarse aerosol spray produced with compressed gases, e.g. furniture polish and window cleaner. Nitrogen is insoluble in water and other solvents, and therefore remains separated from the actual pharmaceutical formulation.

The major part of the contribution by solvents to ozone creation is from the solvents included in products from which the solvent will evaporate in use such as paints, polishes and adhesives. In domestic use as well as in the smaller industrial uses solvent recapture is impracticable and formulation of the product to reduce its solvent content or to use solvent with low POCP (water best of all) is the only route to improvement. 

A wide range of perfumes, predominandy based on synthetic ingredients, are used in household products. They are used to make cleaners smell more pleasant than their chemical ingredients. Some of the cleaners that usually contain fragrances in their compositions are softeners and laundry detergents, dishwashing products, floor cleaning products, furniture polish, and bathroom cleaners. Air fresheners also contain perfumes in their formulations. 

A process used almost exclusively for polyvinyl chloride resins is calendering. A formulation of resin, plasticizer, colorants, stabilizers, etc. is heated and passed through polished and heated rollers, which are successively placed closer and closer together. This same process is also used in production of rubber sheeting or fabric-reinforced plastic. 

There is little commonality in the scientific methods, processes, and formulations required for the wide variety of cosmetics and toiletries in the market. Products range from preparations for hair, oral, and skin care to lipsticks, nail polishes and extenders, deodorants, body powders and aerosols, to quasi-pharmaceutical over-the-counter products such as antiperspirants, dandruff shampoos, antimicrobial soaps, and acne and sun screen products. 

The synthetic isoparaffins are suitable solvents for alkyd and acrylic paint formulations. These virtually odorless solvents and their low surface tensions offer improved flow and wetting properties to the paints. The excellent wetting characteristics of these solvents are desirable in formulations such as furniture polishes, car polishes, and waterless hand cleaners. The low surface tension of these solvents reduces the amount of surfactants needed in emulsified products and affords improved wetting of pigments in ink and coating formulations. The isoparaffins are used as an inert process solvent in the manufacture of polyolefins and certain rubbers. In the slurry polymerization process the isoparaffins afford solvency for the Ziegler-type catalyst and the ethylene monomer, but no solvency for the polyolefin polymer product.
