Lanolin spray is a compound that is often used to clean and condition wool products, such as clothing and diapers. It is also used for the treatment of these items to make them less itchy and more comfortable and smooth to the touch. While lanolin spray isn't expensive in and of itself, if you are constantly using it to condition your baby's diapers, you can go through an ample amount. A homemade recipe can alleviate the cost and worry of running out of lanolin spray.

You may have to go to specialty stores or order online to get your ingredients. Sites such as Makingcosmetics.com offer decent deals on the products, for an ample amount.

Stir the polysorbate 80, liquid lanolin, and your favorite scented oil together into the medium bowl. Make sure to mix them completely together, and that there is no separation. The order in which you add the ingredients does not matter.

Add in the 1/3 cup of water, and continue stirring so that it is visibly mixed.

Place the bowl in the microwave and heat for one minute. It should boil and rise by this time--make sure to use a bowl that accommodates this. While heating, be wary of the mixture boiling over and making a mess in your microwave. Keep a constant watch on it and shut the microwave down before the mixture gets to that point. If the mixture hasn't begun to boil yet by the time the minute is up, continue heating for half a minute or so.

Take the bowl out of the microwave immediately after it has finished heating.

Begin stirring the mixture with your stirring stick as soon as you take it out of the microwave. The mixture will become transparent as you stir it. Keep stirring until the liquid becomes opaque and white/yellowish. If the mixture does not turn transparent at the start, you did not add enough water. Re-add another 1/3 cup of water and re-boil the water.

Let the mixture sit for three to four minutes to cool down.

Add another 2/3 cup of water, stir and let cool.

Pour the homemade lanolin spray into the spray bottle and use.
