  What’s butylene glycol function in Croda’s BTMS-50?

  I couldn’t find any reference to butylene glycol improving emulsions, but it seems to work as a preservative add-on

  But BTMS-25 doesn’t contain it, so it ain’t used as a pellets preservative.

  @gunther - According to their patent (US6638497B2), the function of glycols in their strong quats are to reduce the melting point of the mixture, so as to reduce heating time and potential for thermal degradation of the quat.
