We know you share our concern for our natural environment and the role we play in protecting it. Our values of being eco-friendly, sustainable and environmentally conscious are evident in our ingredients, manufacturing processes and packaging. Our soaps are natural and we promise you packaging that is biodegradable. When it came to sealing our natural glycerin soaps for shipping we had to find something that is 100% biodegradable but still did a great job of keeping our hippo soap bars as fresh as possible for as long as possible. So we use a product called Biolefin, which is a really cool biodegradable (read HOME compostable) product which keeps your hippos dry and safe until you’re ready for them. Once unwrapped, you should put the Biolefin wrapping in with your compost/green bin, where it will bio-degrade into water and food for bacteria and other micro-organisms. Biolefin is totally safe, non-toxic and 100% biodegradable, just like our Hippos.
