At one time, my old company produced a hand cream. From time to time we'd sit in a seminar given by an expert in some area of some product we sold, or might sell. At times they were interesting, in this one the guy said all hand creams are based on glycerin and some kind of fat, or oily substance to coat the skin.
An example is glycerin plus say petrolatum or mineral oil.
The rest of the additives are marketing gimmickry, aloe, Vitamin E, whatever can be advertised but contributes nothing.
