  • Guar Hydroxypropyltrimonium Chloride vs Starch Hydroxypropyltrimonium Chloride

    Posted by tcurious on March 8, 2023 at 1:38 pm

    Can anyone explain the difference between Guar Hydroxypropyltrimonium Chloride vs Starch Hydroxypropyltrimonium Chloride? They seem like they have the same function and can be used in lieu of each other (although it does seem like some formulators may use them together). From the different SDSs out there, it’s clear what the inputs are for Guar Hydroxypropyltrimonium Chloride; the inputs are not clear for Starch Hydroxypropyltrimonium Chloride. THANKS!

    This depends on your application, as so often is the case. Whassup with your formula vector? The guar HPTC is indicated for dilution-deposition of dimethicone and polyquats in hair care shampoos and conditioners. The starch HPTC is used more as a fixative for hair styling products. Neither is great at thickening formulations, if that is any help.

      Thanks!

      I was looking around for hydrolyzed corn starch as a fixative get some styling hold and curl definition into our conditioner and styling product. That said, suppliers sent me Guar HPTC, Starch HPTC and N-Zorbit 2144.

      I’ve already started using Guar HPTC in shampoo for its conditioning properties. But I was stumped on the others since Starch HPTC had little info and N-Zorbit 2144 seemed to be promoted more as a plating agent than as a fixative.

      Thanks for the insight!
