Espana SILK products are all natural, water based, non-oily, biodegradable, hypoallergenic and does not contain petroleum, pyrethrins or alcohol-based chemicals. Espana products are soap-free which mean they contain NO potassium salts or potassium hydroxide, they contain NO renders of animal fat (sodium tallowate) or harsh detergents so they will NOT wash out spot-on topical flea treatments, Espana products are color safe. Espana products are plant based with organic ingredients and PH balanced. Espana products are good for humans and all their pets and are specially formulated to hydrate and reduce static while enhancing the natural luster of coats, manes and tails. Espana products contain NO ethylene alcohol, which is in most competitive products to eliminate grease. Ethylene can be absorbed into the body's blood stream of both you and your pet. It is not required to be listed as an ingredient on product labels, so many other manufacturers use it without anyone actually knowing. Espana products contain NO "Sodium Sulfates" as used in most competitor products. Sodium sulfates will dry out skin and is absorbed into both pet and human blood streams. Espana products are made from organic surfactant blends to clean your skin and your pets skin and hair shaft only, therefore, not going below the skin surfaces.  Espana's "SILK" PROTEINS (Silk means STRONG) are what sets ESPANA apart from the other products on the market as our products have been specially formulated & created to HYDRATE.  There are literally 100's of silicones on the market that are either acid or alcohol based which causes drying and breakage, BUT we are so happy to have a NATURAL SILK BASE providing HYDRATION/ MOISTURIZING being the BIG DIFFERENCE to the coat/hair and skin.
