Extracted from sheep's wool, lanolin is purified to use as a base for ointments, creams, lubricants and a preserver of leather and is also used in cosmetics. Its chemical constitution is cholesterols and it reacts with fatty acids. Some people have reactions to lanolin, so dangers may be involved.
Pesticides
Sheep, as a process to keep their coats free of insects, are sprayed biannually with pesticides. These can cause adverse reactions in people, with rashes and such.
Serious Side Effects of the Skin
Some more serious side effects include a change in your skin such as turning white and soft or soggy or skin infection.
Allergic Reactions
You are allergic to lanolin if you experience itching, severe dizziness or trouble breathing. It is possible your face, tongue or throat may swell.
Sun Sensitivity
Lanolin products may make you more sensitive to the sun, and you may need to allow for use of sunscreen, protective clothing and have limited exposure in the outdoor sun.
Internal Poison
If taken internally, lanolin can cause diarrhoea, intestinal problems and vomiting.
