    Why would you want to mix those two?

    Tego Care PBS 6 works well on its own, it doesn’t need another emulsifier.

      As much as it is safe- conform IFRA guidance.

      Some details from manufacturer’s guidance:

      “Difficult to stabilize ingredients like electrolytes
      and high amounts of urea or ethanol are well
      tolerated by emulsions based on TEGO® Care
      PBS 6.

      TEGO® Care PBS 6 is suitable for the formulation
      of O/W emulsions with all types of cosmetic oils
      at a pH of 4.0 to 8.5.

      TEGO® Care PBS 6 is suitable for systems preserved with natural preservatives such as organic
      acids (e. g. benzoic acid and sorbic acid).

      The recommended usage concentration of
      TEGO® Care PBS 6 is approx. 2.5 to 4.0% in lotions
      and sprays.

      Typical oil phase contents of emulsions based on
      TEGO® Care PBS 6 are 10 - 30% for lotions and
      10 – 20% for sprays.

      Typical combinations for O/W lotions are 2.5 –
      4.0% TEGO® Care PBS 6 with up to 3.0%
      consistency enhancers. Suitable combinations
      include TEGIN® M Pellets (Glyceryl Stearate) and
      TEGO® Alkanol 18 (Stearyl Alcohol) or TEGO®
      Alkanol 1618 (Cetearyl Alcohol) in a ratio of
      50:50.”- meaning from the “up to 3% consistency enhancers”, 1/2 would be glyceryl stearate and 1/2 would be either Stearyl alcohol, or cetearyl alcohol

    TEGO CARE PBS 6 MB is a perfect nonionic emulsifier to pair with Olivem1000 if you are creating a oil in water emulsion such as a cream with added electrolytes. You NEED a nonionic emulsifier to pair with Olivem 1000 as it is Anionic and the nonionic emulsifer will add mildness. It should also help with excess rub in time that Olivem1000 tends to create (soaping effect). If you experience excess rub in time using Span 60 at less than 2% (or another low hlb waxy nonionic emulsifier) can help eliminate that problem. With emulsions you also should use a gum or polymer to add stability.

    You CANNOT use it alone to create a stable emulsion. Over time it will likely separate. Try testing this doing a freeze/thaw test for at LEAST 5 days. If it shows signs of separation, reformulate.

      I think you meant OM 1000 is non-ionic, and best paired with something that has a charge, for ideal stability. 😉
