Optiphen PLUS

INCI: Phenoxyethanol (and) Caprylyl Glycol (and) Sorbic Acid

Optiphen PLUS is a patent-pending liquid preservative from ISP/Sutton which offers broad spectrum preservation without parabens or formaldehyde. This preservative functions particularly well in slightly acidic formulations, and is globally approved. Consisting of Phenoxyethanol (an aromatic ether alcohol), Sorbic Acid (a natural acid that offers protection from yeast, fungus and mold) and Caprylyl Glycol (an emollient base). Optiphen PLUS as a preservative offers the following benefits::

• Globally Approved
• Contains a reliable agent, sorbic acid, for anti-fungal and anti-mold activity
  • unlike Optiphen ND which contains benzoic acid which may be de-activated by non-ionic emulsifiers and surfactants
  • unlike regular Optiphen which contains no acid and no protection from mold, fungus or yeast
• Highly effective broad spectrum antimicrobial
• Effective at pH levels below 6
• Non-formaldehyde donor
• Paraben-free
• Non-isothiazolinone
• Imparts emollience
• Compatible with most raw materials *
• Excellent safety and toxicological profile
• Heat tolerant to 176F

SPECIFICATIONS

• clear to light yellow non viscous liquid
• characteristic odor
• water miscible
• store tightly closed: cool, dry, protected from direct sunlight
• 24 month shelf, properly stored / handled

GUIDELINES

• 0.75 to 1.5%
• add to water phase (for cold process) or at cool down (preferred method) *
• best in formulations with final pH below 6.0
• may solidify at temperatures below 77F, if this occurs gently heat at 104 to 122F and stir to ensure homogeneity
• the change to Optiphen PLUS may result in thinner emulsions so it is best to run a small test batch and increase thickeners as necessary to maintain product consistency

NOTE:: Every personal care formulation requires a preservative that meets its specific needs. New, and modified, formulations should be challenge tested to ensure adequate preservation.

* Like with most preservatives, high phthalate containing ingredients may cause a color shift. Another choice of preservative should be used in these cases.
