The main difference is that na tural vegan organic soap is made from plant-based, certified organic ingredients, free of animal products and synthetic chemicals, while regular soap can contain animal fats, synthetic fragrances, and detergents that may be harsher on the skin and the environment. Natural soaps are generally better for sensitive skin and the planet due to their moisturizing ingredients and lower environmental impact, whereas regular soaps prioritize cost and shelf life over skin and eco-friendliness.
