Pullulan DuoLux CM

Pullulan DuoLux CM leaves a thin, clear film on the skin which, once dry, smooths its surface. This polysaccharide obtained by fermentation is added to the water phase of serums, toners, masks, cleansing products and hair products, where it works as a low-viscosity film-forming agent . At a usage rate of 0.5–5% , it gives the formulation a smooth feel and a light tightening effect without thickening it or making it sticky. The ingredient is of biotechnological origin. It is produced by fermentation of the microorganism Aureobasidium and is supplied in both food-grade and cosmetic-grade quality. What Pullulan does in a formulation Film-forming effect – after application and water evaporation, it forms a continuous, transparent and flexible film on the skin or hair. At standard dosages it is not greasy and feels smooth to the touch. Tightening effect – as the film dries, it slightly tightens the skin surface. The complexion appears firmer and smoother shortly after application; the effect is cosmetic and temporary, lasting until the next wash. Low viscosity – a 10% solution has a viscosity of only 15 – 180 cP , significantly less than common thickeners. It does not thicken the formulation even at higher dosages, making it suitable for liquid and spray products. Slip and adhesion – the film adheres well to the surface and improves the slip of the product on the skin when spreading serums and light emulsions. Barrier function – the manufacturer states that the film limits skin contact with harmful environmental substances. The extent of this effect depends on the dosage and com
