Nonmedicated ointments are indicated for moderate to severe dry eye, especially with lagophthalmos, persistent inferior corneal stippling, or severe epithelial compromise. Esters of latty acids with long-chain alcohols, such as petrolatum, mineral oil, lanolin, and lanolin alcohols, serve as lubricants and create a lipid layer, retarding evaporation. Although these preparations (Table 14-2) melt at the temperature of the ocular tissue and disperse with the tear fluid, they appear to be retained longer than other ophthalmic vehicles. Because of their molecular... 

Lanolin alcohols is used in topical pharmaceutical formulations and cosmetics as a hydrophobic vehicle with emollient properties, e.g., in preparations for dry skin and dry eyes. It is also used in the preparation of water-in-oil creams and ointments at concentrations as low as 2% w/w. The proportion of water that can be incorporated into petrolatum is increased threefold hy the addition of 5% lanolin alcohols. Such emulsions do not crack upon the addition of citric, lactic, or tartaric acids. 

Desoximetasone emollient cream 0.25%, desoximetasone gel 0.05%, desoximetasone ointment 0.25%, and desoximetasone emollient cream 0.05% contain the active synthetic corticosteroid desoximetasone. The topical corticosteroids constitute a class of primarily synthetic steroids used as anti-inflammatory and antipruritic agents. Each gram of emollient cream 0.25% contains 2.5 mg desoximetasone in an emollient cream consisting of white petrolatum USP, purified water USP, isopropyl myristate NF, lanolin alcohols NF, mineral oil USP, cetostearyl alcohol NF, aluminum stearate, and magnesium stearate. Each gram of gel 0.05% contains 0.5 mg desoximetasone in a gel consisting of purified water USP, SD alcohol 40 (20%...

Wool fat (Adeps lanae this is a wax and not a fat) is used in ointments and in eye ointments and increases the penetration ability of lipophilic ointments. A drawback is the chance of contact allergy. Due to the presence of free surface active lanolin alcohols Wool fat has a greater power to absorb water than flie other waxes. Lanolin (Adeps lanae cum aqua) is an emulsion of 25 %water in 75 % Wool fat. 

The vast majority of ophthalmic ointments are essentially lipophilic and consist of mixtures of hydrocarbons. To improve spreading over the comeal surface and mixing with the precorneal him. small amount.s of lanolin and/or lanolin alcohols, impaning to the ointment base W/0 emulsifying properties, can be added. Suspension-type hydrocarbon ointments share with their "solution-type" homologs a poor patient acceptance, mostly due to their greasiness and vi.sion-blurring effect therefore, they are preferentially applied as nocturnal medications.

The lubricating ointments are composed of a mixture of white petrolatum, mineral oil, liquid or alcohol lanolin, and sometimes a preservative. These highly viscous formulations cause considerable blurring of vision, and consequently they are used primarily at bedtime, in critically ill patients, or in very severe dry-eye conditions. Such aqueous and ointment formulations are only fair substitutes for the precorneal tear film, which is truly a poorly understood lipid, aqueous, and mucin trilaminar barrier.

Waxes are esters formed from long-chain (16 or more carbon atoms) fatty acids and long-chain alcohols. The general formula of a wax is the same as that of a simple ester, RGOOR, with the qualification that R and R are limited to alkyl groups with a large number of carbon atoms. Natural waxes are usually mixtures of several esters. Wax coatings on leaves help to protect the leaves from disease and also help the plant to conserve water. The feathers of birds are also coated with wax. Our ears are protected by wax. Several natural waxes have been used in consumer products. These include carnauba wax (from a Brazilian pahn tree), which is used in floor waxes, automobile waxes, and shoe polishes, and lanolin (from lamb s wool), which is used in cosmetics and ointments. Lanolin also contains cholesterol. 

Lanolin, wool fat, wool wax the fatty or more correctly waxy substance secreted by the skin of the sheep, m-p. 36-42°C. L constitutes up to 50% of the wei t of raw wool. It is a complicated mixture of fatty adds, alcohols, fats and waxy substances. The latter are chiefly esters of steroids (cholesterol and lanoster-ol) and long chain aliphatic alcohols with higher fatty acids, which are 6-hydroxylated or carry a terminal isopropyl or isobutyl residue. L. is obtained from raw wool by extraction with organic solvents or soap solutions. It forms water-in-oil suspensions, and is used widely in the pharmaceutical and cosmetics industries (as Adeps Lanae) as an ointment base.
