Oregon Rain handmade soap bars are really made with Oregon rainwater that we collect, filter and purify ourselves. Our handmade soap is made using a method called cold process soapmaking. We use rainwater to make our handmade soap because it's a soft water and a natural resource adding uniqueness to our soap bars. We also use olive oil for its skin conditioning and moisturizing properties and coconut, rice bran and castor oils to provide a gentle, creamy, fluffy lather. We use natural colorants, herbs, nutrients and essential oils for aromatherapy benefits when we can. Otherwise, we use cosmetic grade colorants and fragrance oils for vibrant color and scent. Each handmade soap bar is aged for at least 30 days. Not only will the soap last longer, but it will also be at the optimum mildness.
