THEORY:

A lotion is a low- to medium-viscosity, topical preparation intended for application to unbroken skin; creams and gels have a higher viscosity. Most lotions are oil-in-water emulsions, but water-in-oil lotions are also formulated. Lotions are usually applied to external skin with bare hands, a clean cloth, cotton wool or gauze; creams and gels usually only with one's fingers or palms. Many lotions, especially Hand Creams and Face cream are formulated not as a medicine delivery system, but simply to smooth and soften the skin— these are particularly popular with the aging and aged demographic groups, and in the case of face usage, can also be classified as a cosmetic in many cases.The key components of a skin care lotion, cream or gel emulsion (that is mixtures of oil and water) are the aquous and oily phases, an emulgent to prevent separation of these two phases, and, if used, the drug substance or substances. A wide variety of other ingredients such as fragnances, glycerol, petrolium jelly, dyes, preservatives proteins and stabilizing agents are commonly added to lotions.

USES:
