We (www.littledrippers.com) get asked frequently how to modify a lotion or balm recipe to adjust the consistency. We have found that the simplest way to make a lotion or balm either stiffer (less greasy) or softer is simply by adding or reducing the portion of hard wax (we only use pure beeswax).
Start with twenty to twenty-five percent less wax than called for in a given recipe. The wax can always be added to stiffen the product but once you add too much you may as well start over. Let your product cool to room temperature and try it out. If it is too soft then melt it all down again and add another ounce or half ounce of wax and test it again.
We have been able to make significant changes in the texture/consistency of our lotions and balms by this simple procedure without waisting any product.
