What is the difference between lanolin liquid and lanolin semi-solid?
The semi-solid Lanolin contains complete solid lanolin and a percentage of wool conditioning oils. That's what makes it smooth and "spreadable". Liquid Lanolin has been centrifuged to have the solid wax particles removed from the lanolin. That's why it is clear. Both are just fine for lanolizing. The solid can be scented, the liquid cannot. The liquid is usually slight cheaper, because it lacks the wax portion of the lanolin molecule.
Lanolin, acts as a skin ointment, water-proofing wax, and raw material.
Liquid Lanolin is produced from lanolin that is subjected to low temperature fractional crystallization to isolate the liquid esters of regular anhydrous lanolin. The color and odor of lanolin make it ideal for use in lip care products where color is important. It can be used as a substitute for mineral oil in any type of skin care oil or formulation. It provides superior emolliency and protection from epidermal moisture loss.
Cosmetic Uses: Lanolin is great in balms, hair treatments and conditioners, body oils, bath oils, rich creams and other products where high emolliency is needed.
