Home Cosmetic Science Talk Formulating liquid soap paste

    I would love to be able to sell liquid soap but without all the plastic bottles etc. I know this is something way down the track. As I am still new to making liquid soap and want to use my soap for a long time before selling. But just thinking of the logistics down the track. Maybe just selling the paste in a sachet and with a reusable bottle that the customer then dilutes the soap paste with warm water. Would this work?

    I mean I would love the paste to be dried or would the KOH never dry? I am new to the liquid soap area as I love bar soap because of the zero waste aspect but want to investigate other options.

    thank you in advance for any insight and assistance.

    Adding tap water will add Pseudomonas aeruginosa - a typical water bug and one of the worst for cosmetic contamination. Using the same bottle with the added water will give it a chance to adapt and grow in your product.

      so are these companies that are doing similar just have a bunch of preservatives and sulfates in their products to allow customers to add the water?

        Imagine companies doing it know (perhaps care) nothing of the risk.

    If you’re concerned about the waste, I would recommend doing refills that use less packaging over all such as a larger amount in a single container, maybe try selling in more eco-friendly packaging? For example, use packaging made from renewable resources and is biodegradable. I found bottles that 1/3 of the plastic used to make the bottle was replaced with straw. Very cute and as far as I know, that SOUNDS more eco-friendly than a 100% plastic bottle. I would caution though too that a lot of recycling and eco-friendly mumbo jumbo is all just marketing hype and I’d go as far as to say that a decent amount of it is just marketing hype or outright lies so they have a story to sell their products.

    Customers are not going to be bothered with the hassle of doing that. Realistically you are competing with large companies that can put a bottle of soap on display in Walmart for $2.
