Lanoline (from the Roman language l?na `wool' and of oleum `oil'), also named woollen lard or woollen lard, is a lax excreted by the tallow gland of wool-bearing cattle. The lanolin used by man comes from native races of sheep bred especially for their wools. Many pharmacopeias have described lanolin as lanolin (adeps lanae); however, since lanolin does not contain glyceride (glycerol ester), it is not real adipose.
1 ] Lanolin is primarily composed of stereo-ester. 3 ] Lanolin's sealing ability helps lambs remove moisture from their fur. Some races of shepherds are producing large quantities of lanolin. Lanolin's unique combination of long-chain ester, hydroxy ester, diester, lanolin alcohol and lanolinic acid is not only a precious commodity, but also the basis for the manufacture of a whole range of lanoline derivates with far-reaching chemistry and physics as well.
1 ] The lanoline derivates obtained from these procedures are used both in high-quality cosmetic as well as in dermatological treatments. Lanolin hydrolyses produce lanolin alcohol and lanolinic acid. Lanoline Alcohol is a potent sources of Cholesterin (an important fat for the skin) and strong water-in-oil emulsifier; they have been used intensively in dermatological care for over 100 years.
1 ] Approximately 40% of lanolinic acid is AHA. The following chart shows detailed information about the AHAs insulated from lanolin. Another manuscript, also included in the US Pharmacopoeia XII in 1992, was titled "Modified Lanolin". Lanoline according to this Monography is designed for more demanding uses, e.g. in open sores.
The European Pharmacopoeia established limit values for pesticides residues in its lanolin monomer. In July 1976, the European Cosmetic Directive established that lanolin-containing cosmetic products should be labeled accordingly. Although this decision was only in effect for a brief while, it harmed both the lanolin plant and lanolin's name.
7 ] The Cosmetics Directive was only applicable to the use of lanolin in cosmetics; it was not applicable to the many hundred different uses in dermatology developed for the care of dermatology-problems. Lanolin's barriere-repairing characteristics are better than those of kerlatum and glycerine.
A small preclinical trial performed on volunteers with horribly dehydrated (xerotic) palms showed that lanolin is better than kerosene in that it reduces the effects of drought and flaking, ruptures and grazes, and pains and itching. Another trial found that a high degree of lanolin cleanness is clearly better than that of kerlatum in the treatment of surface sore.
Lanoline is used in a wide range of industries, from stainless steel coating to lubrication. A number of yachtsmen use lanolin to produce slipy surface on their props and tail equipment to which sea bucks cannot stick. Merchandising up to 85% lanolin in up to 85% lanocote is used to avoid ship mountings from corroding, especially when two different metal materials come into mutual and salt water-contacting.
Its hydrophobic characteristics make it a precious lubricating fat in many areas where it would otherwise pose a challenge. Ballplayers often use it to make their glove softer and more resistant (shaving lanolin is commonly used). Waterfree lanolin is also used as a lubricating agent for wind instruments' slide tuners.
Lanoline can also be recovered in wool clothing to make it waterproof and dirt-repellent, e.g. for fabric nappies. Lanoline is also used in lips balms like Carmex. Lanoline is sometimes used by those with continual respiratory hypertension treatment to relieve irritations with mask, especially nose pad mask, which can often cause soreness in the nose holes.
Lanoline is a favourite addition to mustachewaxes, especially to "extra-solid" types. Lanoline is used as the main lubricant ingredient in aerosol-based messaging fluids when recharging shells. Incorporated hot 1:12 with high concentration alcohol (usually 99%), the alcohol functions as a support, which quickly vaporizes after being applied and leaves a thin lanolin layer to avoid the mess being seized in shredding moulds.
Lanolin, blended with substances such as neatfoot fat, bees wax and glycerine, is used in various types of leathers treatment, e.g. in some of our nut soap and leathers conditioners. Raw lanolin accounts for about 5-25% of the total mass of newly clipped yarn. A merino sheep's yarn produces approx. 250-300 ml of recyclable fat.
Lanoline is obtained by rinsing yarn in warm tap running down with a specific lanolin wash to eliminate soiling, raw lanolin, perspiration salt and anything else that sticks to the lambs. During this wash cycle, the fat is continually eliminated by centrifugal traps, which convert it into a waxy compound that melts at approx. 38 °C (100 °F).
