Thermotropic Properties

In this work, the effect of thin films on the thermotropic and thermo-optical properties and peculiarities of the phase transitions between the smectic A and isotropic liquid have been investigated. Peculiarities of the heterophase regions of the straight smectic A-isotropic liquid and reverse isotropic liquid-smectic A phase transitions have been studied. Change of morphologic properties of the heterophase regions, shift of the phase transition temperatures and the change of temperature widths of these heterophase regions under thin film influence have been observed.

Topical Applications

The name ‘lanolin’ covers wool fat, wool wax and wool alcohol as well as their various constituents. Lanolin is an emulsifier present in many topical medicaments, such as ointments and creams, and in many cosmetics. ‘Parabens’ is the collective name for the alkyl (methyl, ethyl, propyl and butyl) esters of p-hydroxybenzoic acid used as preservatives in cosmetics and other topical applications, especially creams and lotions: they are amongst the most satisfactory preservatives. Lanolin and parabens are the constituents of the vehicles used for local applications which most frequently cause contact hypersensitivity.1 For example, it has been estimated that about 1–2% of patients with eczema or dermatitis are allergic to lanolin, though such allergy is very rare in people with a normal skin. The possibility of contact allergy should be considered in any case of persistent or recurrent eczematous dermatitis which responds poorly to treatment, and the patient should be patch-tested.

(+)-10-Methyldodecanoic acid and 12-methyltridecanoic acid have been isolated from the acid fraction of wool wax. These acids have a high inhibitory activity against Gram positive bacteria, but not against Gram negatives or fungi. A steric relationship with the Gram positive cell wall surface is suggested.
