Woolgrease Fatty Acids
Description
Wool fat acids
Composition and description
Wool fatty acids differ from lanolin fatty acids by their low acid content. They are produced by chemically processing wool fat, a natural and renewable raw material obtained by cleaning (washing) raw wool.
It is a very complex mixture of semi-refined wool grease and fatty acids. Chemically, it is a wax and a complex mixture of esters, diesters and hydroxyesters of lanolin alcohols with high molecular weight lanolin acids.
Peculiarities
Wool fatty acids differ from lanolin fatty acids in their low acid content. This makes them suitable for use on materials that may be susceptible to acids. Fatty wool acids are an ideal choice for technical applications where lanolin and neutral wool grease are not cost effective.
Application
Wool fatty acids are versatile raw materials for use in anti-corrosion agents, lubricants, cutting fluids, dehydrating chemicals, leather processing and others. Wool fatty acids are a better rust preventative than petroleum jelly due to their higher affinity for metal surfaces. Once heated, wool fatty acids can be easily applied to surfaces and form a flexible but stable film after cooling. In particular, metal soaps made from fatty acids such as calcium and magnesium are long-lasting and effective lubricants.
Safety
Wool fatty acids differ from lanolin fatty acids by their low acid content. They occur naturally and are biodegradable. This makes them suitable for technical applications where their release back into nature cannot be avoided, such as protecting ships and cars from rust.
Features of application
Lanolin fatty acids are easy to use and can be processed either cold or molten. They are not hazardous and melt easily, with a relatively low level of volatility.
