Commercial shaving creams usually consist of some sort of animal-based or hydrogenated vegetable-based fat, such as stearic acid, chemicals meant to create the right texture and pH, fragrances and dyes, and water. They may have one or two natural ingredients, such as aloe vera gel, or a vegetable-based fat source, but for the most part, they have a significant amount of toxic ingredients. In commercial creams petroleum based derivatives, propylene glycol (an ingredient in industrial antifreeze), benzaldehyde (irritating to mucous membranes), and camphor (easily absorbed through the skin, can cause dizziness and nausea when inhaled) are often used.
