The real questions are: “Paper or Plastic?” And, what does it take to make each type “shelf stable?”

So, some have asked if we will ever do liquid soaps like hands soaps, body washes, and liquid shampoos and conditioners. The answer is, probably not in the near future. Why? Because we are trying to take the lead in preparing for a new world without plastics. Liquid requires a container. And, while glass is a potential recyclable option, it’s heavy and shipping is not getting any cheaper. So, we subscribe to the KISS concept. The simplest option is to make solid products. We do make scrubs and balms that we ship in recycled tin containers. But, we’re not worried about whether they get recycled again because metal has a tendency to return to its natural oxidized ore state, especially when exposed to saltwater. And, as we can find suppliers, we have been switching to the most compostable packaging that we can find.

There are advancements being made in biodegradable plastics made from corn starch, hemp, and bamboo. Those would be viable options for shipping liquid soaps, but then the question of, should we, comes up. Hard bar soaps require less preservatives than liquid soaps because bacteria cannot move as easily through a solid matrix. Liquids, on the other hand, provide a wonderful environment for bacteria, so therefore requires preservatives. Preservatives that are more potent than just the natural sea salt and citrus compounds that we use. Enter the world of harsh toxic chemicals.

To extend the shelf life of a liquid soap product to longer than three to six months requires antibiotics and mildewcides. Most of these chemicals serve one purpose and only that purpose — to serve a t
