2 dermosoft products cover many cosmetic functions features natural antimicrobial activity The product line dermosoft products are carefully chosen multifunctional cosmetic ingredients. The well balanced product profiles are tailored to the needs of cosmetic formulations. Basic cosmetic functions like hydrating, conditioning, masking and others are combined with an excellent antimicrobial profile. dermosoft products will meet many of your requirements for the improvement of cosmetic formulations and along the way protect the product against microorganisms. With the aid of dermosoft cosmetic products can easily be formulated without traditional preservatives. The product s active principle is sodium lauroyl lactylate which is produced from 100 % natural components. The surface active properties of will help to stabilise formulations as a co-emulsifier. The activity against gram-positive bacteria and yeast makes this raw material a valuable component in deodorant formulations. And finally, when combined with other dermosoft types, the good antimicrobial activity of gives a contribution to yield self preserving products with no further need for traditional preservatives. Application is a transparent highly viscous, almost solid liquid that is water soluble and can easily be employed in Rinse-Off-concepts as well as in O/Wemulsions 1,2. For the incorporation in your formulation add the recommended amount of to the waterphase in a hot process. When used at higher concentrations may have a weakening effect on emulsion stability. Please check stability issues carefully during product development. Efficacy and easy application are the cornerstones of Characteristics of Appearance INCI Colourless highly viscuos liquid Sodium Lauroyl Lactylate Recommended dosage 0,5 2,0 % ph-range 4,5-5,5 Regulatory status CMR-ingredients Registered in EU, Japan No

3 Cosmetic functions Different cosmetic functions are obtained with Co-emulsifier is often employed as a co-emulsifier. The amphiphilic structure allows it to enter the interphase between oil and water and due to its anionic charge will inhibit a coalescence. There is a long history of examples for various cosmetic applications as a co-emulsifier with gel forming abilities 1,2. Acidifying contains in its molecular structure natural lactic acid. Its low acidity makes it an ideal candidate for a gentle acidifying effect on human skin. Thus the natural acidic level of the skin can be maintained for a longer time. The correlation between physiological ph and healthy skin has been shown in many studies and there has been evidence that micro organisms like Propionibacterium acne and Staphylococcus aureus are significantly reduced, when the normal ph on human skin is maintained stable 3. Antimicrobial efficacy Although may be employed for its additional valuable cosmetic functions, the selective antimicrobial activity can be employed in certain product concepts. The activity against gram-positive bacteria and yeast makes it particularly useful for deodorant products and anti dandruff formulations. Especially the troublesome Pityrosporum ovale (=Malessezia furfur) and Corynebacterium xerosis are killed rapidly by. Furthermore it may help to improve the microbiological stability of the product. In most cases in combination with other antimicrobial ingredients - it will allow to eliminate unnecessary preservatives from the product. Best results are achieved in the ph-range between 4,5 and 5,5.
