  Preservative queries for a hair conditioner

  Preservative queries for a hair conditioner.

  (1) I am considering using Optiphen ND. Is anyone aware of issues with this preservative if the recipe includes Cetrimonium Chloride (cationic conditioner) and Hydrolyzed Soy Protein? I remember reading somewhere that these may inactivate the Optiphen ND.

  (2) As an alternative I am considering using Phenoxyethanol &  Benzyl Alcohol. Any opinions/advice on these?

  (3) Another option is Potassium sorbate & Phenoxyethanol. Again, any opinions?

  Thanks
