Amphisol K

AMPHISOL® K is an anionic oil/water emulsifier and stabilizer for the preparation of skin-care and sun-care products. It is used to prepare cost-effective, homogeneous and stable emulsions over a wide pH range (4-+9), but preferably at the pH of the skin (pH 5.5-5.8).
Because it is used at low levels, AMPHISOL® K is well-suited for the development of quality stable water-resistant suncare products.
As well as the intro video below, DSM have also created a wide selection of videos to help explain the key benefits of the product and to provide some formulation tips.
Key benefits and how to overcome some common challenges:
