    Silicon replacement

    Defoamer for skin leave-on applications

    Bio-based, non-persistent alternatives to dimethicones 100 CST and 350 CST

    Silicones, or polysiloxanes, are key ingredients in personal care formulations like creams and lotions. In these formulations, they prevent foaming while at the same time providing a pleasant sensory experience – the silicone feel. Unfortunately, polysiloxanes exhibit very low biodegradability.

    The challenges we face

    The defoaming activity of biodegradable alternatives is often lower and depends to a large extent on other ingredients in a cosmetic formulation. Alternative defoamers often influence the sensory experience offered by a cosmetic formulation in an undesired way. We would love to be able to use a fully biodegradable defoaming system in skincare creams and lotions

    If you can identify biodegradable defoaming systems that show attractive performance in emulsions, let’s talk. We are very interested in any ideas on how to generate a silicone-like sensory experience without using polysiloxanes.

    Our expectations on your ideas

    All ideas and products are to be assessed according to the following criteria:

    • Biodegradable, non-persistent in nature
    • If possible, completely bio-based, but at least 50% natural carbon content
    • Sustainable sourcing
    • Comply to the Principles of Green Chemistry and Green Engineering
    • No hazardous material labels

    Should you be unsure about any of these aspects in relation to your idea, product or technology, we would be glad to answer your questions.

    We look forward to working with you. Submit your proposals now!
