@milliachemist,
There are basically 4 kinds of soap-making:
1) Large-scale industrial - if your name isn’t DuPont, you can’t compete. These people use soap kettles bigger than most peoples houses. Tiny profit margin, even for the big players.
2) Small-scale industrial - You need a point of difference to sell your soap (natural, or hypo-allergenic, or moisturizing, etc.), but it’s basically the same style of product that the big guys sell. Small profit margin - barely adequate for most manufacturers. Labor costs vary depending on the level of automation installed.
1) Large-scale crafting - Decorative, unusual soaps that use much more labor than industrial soaps - there’s probably a smaller market for these soaps but a higher profit margin - depending on how much your labor costs. Not normally sold in the usual retail channels, either.
2) Small-scale crafting - Again, decorative, unusual soaps that use much more labor than industrial soaps. Smaller volume so smaller capital investment, but higher labor costs. It’s mostly a hobby for the majority of people doing this, or at best a weekend business.
Which were you thinking of getting into?
