Details:

LANOLIN
 

DESCRIPTION 
LANOLIN is a pale yellow, tenacious, unctuous substance obtained from the wool of sheep, having a faint but 
characteristic odor.
CHEMISTRY  
LANOLIN is classified chemically as a wax, being a complex mixture of naturally occurring esters and 
poly-esters of 33 high molecular weight alcohols (principally sterols) and 36 fatty acids. It is 98% ester 
minimum, of which the fatty alcohols and fatty acids comprise an approximately 50/50 ratio.
TYPICAL COMPOSITION OF LANOLIN
Esters of sterols and triterpene alcohols                                35.4%
Esters of aliphatic alcohols                                            23.7%
Monohydroxyesters of sterols and of triterpene and aliphatic alcohols      20.0%
Di- and polyhydroxyesters and free diols                                7.9%
Free aliphatic alcohols                                                 5.6%
Free Sterols                                                          4.1%

APPLICATIONS
COSMETICS,LANOLIN is an extremely effective emollient in restoring and maintaining the all important 
hydration (moisture balance) of the stratum corneum, and so prevents drying and chapping of the skin. Equally 
important, it does not alter the skin's normal transpiration. Lanolin has been shown to cause the water in the skin 
to build up to its normal level of 10-30%, by retarding without completely inhibiting trans-epidermal moisture 
loss. Lanolin has the unique property of absorbing twice its own weight of water. Lanolin has the physical 
properties of increasing adhesion to dry skin, and forming protective films on the skin. Lanolin is compatible 
with most fats and waxes used in cosmetics and pharmaceutical preparations. Lanolin is self emulsifying,

producing very stable w/o emulsions with water and is often used in this hydrous form.
Lanolin is suggested for use in the following 
Baby preparations,Hair Protection ,Lipsticks,Paste Shampoos,Shave Cream,Sunscreens,Burn cream                   
Hand Soap, Lip cream,Make-Up ,Pet Products,Hair Spray Plasticizer ,Protective Creams and Lotions
