Euxyl® K 703

Euxyl® K 703 is replacing Optiphen ND on our website offerings.

Euxyl® K 703 is a complete preservative system and is paraben free and formaldehyde free. It is effective against both Gram-positve and Gram-negative bacteria, mold, and yeast. 

It is a mild globally-approved preservative consisting of a liquid blend of phenoxyethanol, benzoic acid, and dehydroacetic acid.

Benzoic acid is a simple aromatic carboxylic acid widely distributed in nature in the free state or in the form of salts.  Appreciable amounts are found in gum benzoin, in cranberries, and other like berries. The free acid is found in prunes, ripe cloves and oil of anise seeds.  In addition to being used for cosmetic preservation, it is also used as a preservatives in foods, for pharmaceutical and medicinal uses and as an ingredient in antiseptic ointments for treatment of fungal infections of the skin.

Dehydroacetic acid is a cyclic ketone acid which has anti-fungal and some antibacterial properties. 

Applications

Euxyl® K 703 is recommended for use in multiple personal care products including shower gels, shampoos, body washes, creams, lotions, and wet wipes.  It is not suitable for anhydrous products.  Due to the presence of the organic acids in the system, Euxyl® K 703 offers broad spectrum protection against bacteria, yeast, and mold and is effective in applications where the pH is not above 6.0.

Formulation Guidelines

  • Euxyl® K 703 is fully effective both in anionic as well as cationic and non-ionic systems
  • Offers good head space protection in packaging
  • Euxyl® K 703 has limited solubility in water and non-polar solvents.
  • Euxyl® K 703 exhibits no interaction with sulphite ions
  • Euxyl® K 703, in the presence of iron ions, e.g. from mineral thickeners, may result in yellow discoloration of a formula
  • The recommended pH range for formulations is between pH 3 - 6.  Efficacy is increased by reducing the pH value of the final formulation.
  • Prolonged heating periods greater than 176°F/80°C should be avoided.  It is advantageous to add Euxyl® K 703 in the cooling phase, e.g. with the fragrance, at less than 104°F/40°C.
  • In aqueous products with low emulsifier content, intensive mixing is recommended to achieve a uniform dispersal of the preservative.

Euxyl® K 703 contains:

  • Phenoxyethanol          78.0 - 84.0%
  • Benzoic Acid              11.0 - 13.0%
  • Dehydroacetic Acid     6.5 -   7.5%

While Euxyl® K 703 is classified as a "mild" preservative as formulated, the raw material should be handled with care as the full strength preservative causes severe eye irritation and may cause tissue damage.  Read the MSDS before use and follow recommended guidelines for handling, including Safety Goggles!

It is with great sadness we have discontinued shipping to Australia due to the Australian government shifting their burden of tax collection and remission to foreign sellers. Given there is no reciprocal agreement between the USA and Australia for excise tax collection, we are declining to register with Australia and start burdensome international tax collection on their behalf. Please note, this also includes the use of package forwarders as the tax collection burden is still the seller's responsibility. We're unhappy, you're unhappy, but unless the situation changes, this is where we are. Jenny

Our Customers Say...
I purchase a 5LBS bucket of Shea Nilotica from Lotion Crafter (my first time ever purchasing off this site). The creamy, buttery, light yellow color of it is amazing!!!! It is super soft, light scented, and looks like vanilla ice cream. I am VERY happy with my purchase,and will certainly purchase again. I use by itself on my skin and mix in my whipped body butters. It isn't grainy at all. 5 STARS!!
Charmaine Pitt, (SuriiShae Naturals)

WOW! How fun to make my own Quality skin care products. I'm financially challenged and I love that I can make a product that sells for $100 for a fraction of that! If you can follow a recipe, than you can follow these instructions.I recommend ordering the scale and paddle mixer, too. They're a time saver. Thank you Lotioncrafter!
