Does anyone have experience with Colloidal Oatmeal Lotion formulation for eczema?
I’m interested in making a product similar to Cetaphil’s Baby Eczema Soothing Colloidal Oatmeal Lotion. I looked through the forum and still had a couple questions before I tried formulating. I appreciate any help you can give. The goal would be to make an OTC lotion for adults that can help relieve eczema flare ups.
Here are the ingredients for the Cetaphil lotion:
Colloidal Oatmeal 1%
Allantoin, Arginine, Behenyl Alcohol, Butyrospermum Parkii, (Shea) Butter, Caprylic/Capric, Triglyceride, Caprylyl Glycol, Ceramide NP, Ceteareth-20, Cetearyl Alcohol, Cetyl Alcohol, Citric Acid, Cyclopentasiloxane, Dimethiconol, Disodium EDTA, Disodium Ethylene, Dicocamide PEG-15, Disulfate, Glycerin, Glyceryl Stearate, Glyceryl Stearate Citrate, Helianthus Annuus, (Sunflower) Seed Oil, Niacinamide, Panthenol, Pentylene Glycol, Sodium Hyaluronate, Sodium PCA, Sodium Polyacrylate, Sorbitol, Tocopheryl Acetate, Water
1. If I were to use this as a template to make my own lotion, what ingredients should I start with to make a bare bones lotion with moisturizing and occlusive effects? I would want to omit the marketing ingredients and just make a simple lotion that incorporates the colloidal oatmeal, glycerin, silicones, emulsifiers, and oil phase.
2. After reading through the forum the plan is to make a slurry of the colloidal oatmeal and water then add that to the cooldown phase of the main solution. Does anyone have a better method or any tips? Or any advice on working with colloidal oatmeal?
3. I have seen data sheets with Colloidal Oatmeal usage levels up to 10%, some say 5%. What is a level that has shown results for you in the past? I would want to make this product more effective than what is on the market, it’s going to be for personal use only.
