Anhydrous Lanolin USP 40

Wool grease, a naturally occurring raw material obtained through the scouring of raw wool, is refined in multiple steps to create anhydrous lanolin USP. It is manufactured to fully meet the requirements of the current monograph of the USP.

Lanolin USP40 is produced in accordance with USP40 specifications. The initial peroxide value is very low because it is delicately manufactured in modern facilities. Lanolin USP40 therefore doesn’t require any additional stabilizers.

Lanolin USP40 is most frequently applied as a moisturizer to treat or prevent dry, itchy, flaky, or rough skin. It can also be applied to soothe minor skin irritants like diaper rash.
