If you wish to make skin care products at homes such as lotions and soaps then you need to keep handy a bottle of glycerin. This is used in most beauty products, whether they are facial masks, shampoos, moisturizers, cleansers or soaps.
Here are three simple steps to follow to make vegetable glycerin:
- Mix Oils and Lye
Ingredients required are a cup each of coconut oil, olive oil, lye, salt, and water. The oils need to be combined in a saucepan and heated to blend in together. As the oil heats, two tablespoons of lye and a cup of water need to be added to this mixture. This particular step needs to be done carefully since lye is extremely caustic. Lye should be added to water first and then the mixture added to the oil solution being heated.
- Thicken the Mixture
The mixture needs to be heated to 125 degrees is reached. This can be checked with a candy thermometer and would take 20 minutes approximately. It is necessary to get the mixture at the right temperature and it should be stirred occasionally till right blending is done.
- Finish Making the Glycerin
The mixture needs to reach right consistency after which the pan needs to be removed from heat. Half a cup of salt needs to be added and stirred well; the mixture should remain hot at the time when salt is added. As the mixture cools glycerin and soap separate into distinct layers. The soap layer forms on top while the liquid glycerin remains at the bottom.
The soap layer can be used or discarded as required and the glycerin can be poured into a glass container that is airtight and kept in the refrigerator. This can be preserved for three to four weeks.
