A Hurdle Technology approach has been key and several parameters and methods have been applied to reduce the need for pre-servatives. A combination of formulation aspects like pH and multifunctional ingredients with the right choice of packaging attribute to a greater protection of the products from microbiological growth and contamination. Many aspects are directly applicable for implementation and the hurdle technology approach has been demonstrated in the development of new products at production scale at DermaPharm.
Less preservatives in cosmetics (“MiKoKo”)
DermaPharm A/S and Danish Technological Institute have in the project “less preservatives in cosmetics” developed new methods to minimize the amount of preservatives in cosmetic products and thereby minimize the exposure of preservatives to consumers while retaining product safety and quality required by the Cosmetics Regulation.
