There’s a preservative free cream on the market by a European brand named Avene called Avene Tolerance Extreme Soothing Cream. They have a patented packaging (and I suspect an extremely sterile environment) that allows it. Their ingredient list: Water, Glycerin, Mineral Oil (Paraffinum Liquidum), Squalane, Carthamus Tinctorius (Hybrid Safflower) Seed Oil, Cyclomethicone, Glyceryl Stearate, Sodium Carbomer, Titanium Dioxide.
