Lard is a traditional soap oil used for centuries and is used in conjunction with other more moisturizing oils in modern soap making. Lard will help to create a hard bar of white soap with good foam. Lard is an animal-derived fat, making it unsuitable for those who are manufacturing vegan products. Lard produces a stable, conditioning, long lasting lather. It is very similar to Palm when used in soap making and with the controversy surrounding Palm oil, Lard is a great alternative.
