I am also trying to figure out how I can make a combined shampoo/conditioner bar similar to this: Hybrid Solid Shampoo from Lush.
I posted about this in naturalliving but was hoping I might get more suggestions here. I'm not crazy about the colors or scents used in this product I just want to understand which ingredients are necessary for cleansing and which are necessary for conditioning and what I need to do to make it all stick together.
I'm also trying to make a face wash similar to this: Lavender Seafoam Cleanser by 100% Pure. One of the ingredients is saponified coconut oil. Am I able to just saponify the coconut oil with lye without it becoming to hard and then add in the other ingredients?
I am also still trying to understand all the differences in natural preservatives. Which ones are best for different types of formulations, etc. I noticed that the above product contains Citric Acid, Grapefruit Seed Extract, Rosemary Oil Extract, Vitamin E (a-tocopherol), and Vitamin C (ascorbyl palmitate). I'm assuming the main point of all of these is for their preserving qualities. I was wondering if it's necessary to have so many preservatives in one product and if I could get away with just using one or two of them, and also what the specific benefits of each one are. For example, would I be able to use powdered Calcium Ascorbate instead of the Ascorbyl Palmitate or just regular Vitamin E oil instead of 1-tocopherol?
What are some other natural preservatives and what types of forumlations do they work best in? I want to make several different skin and hair products and was hoping I could get away with buying maybe 2-3 different preservatives that I could use in all of them, and hopefully ones that would be okay and non-irritating for people with skin conditions like rosacea, excema, and psoriasis to use.
Thanks for any help.
