Dumb MechE here whose learned formulating basics from formulating water-based adhesive for tissue/towel market (i.e. glue holding last sheet of the roll down). Looking for comments / suggestions on hand sanitizer formulation to help fight COVID-19 pandemic. Spray formula listed below (still working on gel):
76. % Isopropyl Alcohol (99%)
2.5% D - Sorbitol [Humectant 01]
0.20% Sodium PCA – Ajidew NL-50 [Humectant 02]
0.30% Glucam P-20 (PPG-20 Methyl Glucose Ether) [Humectant 03]
1.5% Isopropyl Myristate [Emollient]
0.15% Tocopheryl Acetate [Skin Conditioner: Vitamin E]
0.15% Potassium Sorbate [Preservative]
q.s. to 100 = H2O: Distilled Water
NOTE: Opted to NOT use glycerin as humectant. We use Glycerin Kosher 99.7% in our transfer glues (adhesive applied to the brown core designed to grab 1st sheet of paper towel/toilet paper during mfg process) and I DON NOT like the stickiness feeling. Went with a skin moisturizing humectant package instead.
Reviewed basic patent information & discussion post comments (thank you @Perry, @Pharma, @em88, @Belassi to name a few) for guidance. I think it’s a solid formula but will test this and other options once our lab opens back up. Please educate me if I’m heading down the wrong path.
