Moisturizer leaving a waxy residue - Lecithin to blame?
I’ve been prototyping a Natural Moisturizing Factor based moisturizer that to some extent mimics the skin’s lipid and NMF profile with the addition of small amounts of vitamin “actives” with the goal of making it suitable for daily use.
One common complaint that I notice myself is that it leaves some residue/a waxy sheen, and before I start eliminating ingredients I wonder what the most likely culprits are: soy lecithin, lanolin, sterols? Here are the ingredients (not in perfect order):
Water, Allantoin, Camellia Sinensis (Green Tea) Leaf Extract, Hyaluronic Acid, Sodium PCA, Sodium Lactate, Sclerotium Gum, Glycerin, Beta-Sitesterol, Campesterol, Stigmasterol, Fish Oil, Lecithin, Polysorbate 80, Lanolin, Squalene, Carthamus Tinctorius (Safflower) Seed Oil, Tocopherol, Niacinamide (Vitamin B3), Pantothenic Acid (Vitamin B5), Ascorbic Acid, Magnesium Ascorbyl Phosphate, Phenoxyethanol, Caprylyl Glycol, Sorbic Acid, Coenzyme Q10, Ceramide 3, Ceramide 6 II, Ceramide 1, Phytosphingosine, Cholesterol, Sodium Lauroyl Lactylate, Retinol, Polysorbate 20, Lactic Acid.
