For routine PCR amplifications. Minimizes evaporation of reactions run in PCR instruments without heated lids. mineral oil is an emollient cleanser and demulsifier of dirt trapped in pores. Mineral oil is excellent for use in cleansers. In leave-on cosmetics, its comedogenicity or lack thereof appears related to the level of raw material refinement; therefore, some suppliers state that their product is non-comedogenic. When used in leave-on preparations, mineral oil’s occlusive capability is considered to help improve the epidermal barrier function. This is a clear, odorless oil derived from petroleum and is not known to cause allergic reactions.

White wax is a chemically bleached form of yellow wax and is used in similar applications: for example, to increase the consistency of creams and ointments, and to stabilize water-in-oil emulsions. White wax is used to polish sugar-coated tablets and to adjust the melting point of suppositories.
White wax is also used as a film coating in sustained-release tablets. White beeswax microspheres may be used in oral dosage forms to retard the absorption of an active ingredient from the stomach, allowing the majority of absorption to occur in the intestinal tract.Wax coatings can also be used to affect the release of drug from ion-exchange resin beads.

Coconut Oil is the oil obtained from the kernel of the nuts of the coconut palm. it has a sharp melting character (narrow plastic range) in that it changes abruptly from a hard, brittle solid to a clear oil with a temperature change of a few degrees, and the transition occurs at room temperature range. it melts at 25°c and is more com- pletely solid than butter at 10°c. these properties make it suited for the preparation of shortenings where brittleness and a large change in consistency with a small temperature change are undesirable. partially hydrogenated coconut oil has hydrogen added to part of the unsaturated carbon bonds to provide a more solid consistency. it is used in confections, baked goods, and margarine. Excipient. coconut oil is used as a cream base, it is a raw material for soaps, ointments, massage creams, and in sunscreen formulations.

It is stable when exposed to air. Coconut oil may be irritating to the skin and cause skin rashes. It is also considered comedogenic.

Paper coating, grease-resistant coating, label varnishes, laminated board, solid-color prints, printing inks, food coatings, microencapsulation, fibers. Zein is a corn protein produced from corn gluten meal. it lacks the amino acids, lysine and tryptophan, so it is not suitable as a sole source of dietary protein. it is insoluble in water and alcohols but is soluble in aqueous alcohols, glycols, and glycol ethers. it functions as a film and coating to provide a moisture barrier for nuts and grain products. it also functions as a coating for confections and a glaze for panned goods.

Medicinal liquid paraffin, also known as paraffinum liquidum, is a very highly refined mineral oil used in cosmetics and for medical purposes. This is a UK definition (British Pharmacopoeia) and the term may have different uses in other countries. The cosmetic or medicinal liquid paraffin should not be confused with the paraffin (or kerosene) used as a fuel.The term paraffinum perliquidum is sometimes used to denote light liquid paraffin. Conversely, the term 'paraffinum subliquidum is sometimes used to denote a thicker (more viscous/oily) mineral oil.

Chiefly in lacquers and varnishes; also in manufacture of buttons, grinding wheels, sealing wax, cements, inks, phonograph records, paper; for stiffening hats; in electrical machines; coating confections and medicinal tablets; finishing leather.

Used as a solvent for fat-soluble drugs.

Usually used in research applications as delivery vehicle for fat-soluble compounds including toxins.
