About QUARK CHEESE
A dairy-derived skin conditioning ingredient with acidic pH that may help gently exfoliate and brighten skin, though it carries risk of sensitization in milk-allergic individuals.
Detailed Analysis
Quark Cheese is a sharp, acidic skim milk cheese used in cosmetics as a skin conditioning agent. Derived from dairy, it contains proteins (casein, whey), lactic acid, and fats. Under the EU Cosmetics Regulation (EC) No 1223/2009, dairy-derived ingredients are not specifically restricted but must be assessed for allergenicity, as milk proteins are known sensitizers in susceptible individuals. The Cosmetics Regulation's Annex III does not list dairy ingredients specifically, but milk or milk-derived ingredients may trigger labeling requirements under Annex II if considered a potential allergen. Formulators must consider the acidic pH and potential for skin irritation in sensitive individuals.
