    I was just able to do my exercise on claim ingredients for an acne product.
    2% salicylic acid, water 80%, sodium PCA 4%, glycerin 4%, azelaic acid 4%, other claim ingredients include sodium polyacrylate, lactococcus ferment lysate, zinc PCA, epilobium angustifiolium flower, niacinamide, bisabolol, allantoin, sodium hyaluronate, lactic acid, sodium benzoate, sodium chloride, sodium metabisulfite, ethylhexylglycerin, phenoxyethanol. Please, can you kindly review this.

      Claims ingredients should only include those that are in the formula but not expected to have much effect. You’ve listed a couple functional ingredients (salicylic acid, glycerin, azelaic acid) and many aesthetic modifier ingredients (phenoxyethanol, ethylhexylglycerin, etc). Claims ingredients depend on what claims are being made but from the list you’ve given I’d say the claims ingredients are…lactococcus ferment lysate, zinc PCA, angustifiolium flower, niacinamide, sodium hyaluronate, and allantoin.
