Title: Natural Preservative Blends with Antioxidant Action
  • Article

Sabinsa has introduced two natural preservatives that also serve as antioxidants and prevent the oxidation of oils and fats in product formulas.

SabiLize Alpha (INCI: Cinnamomum Zeylanicum (Cinnamon) Bark Oil (and) Eugenia Caryophyllus (Clove) Leaf Oil (and) Cymbopogon Citratus (Lemongrass) Leaf Oil (and) Garcinia Cambogia (Garcinol) Fruit Extract (and) Glyceryl Laurate (and) Thymus Vulgaris (Thyme) Leaf Oil)  is a blend of natural active fractions of essential oils and phytoextracts, suitable for use in color cosmetics and personal care products.

SabiLize Beta (INCI: Cinnamomum Zeylanicum (Cinnamon) Bark Oil (and) Eugenia Caryophyllus (Clove) Leaf Oil (and) Cymbopogon Citratus (Lemongrass) Leaf Oil (and) Glyceryl Laurate (and) Thymus Vulgaris (Thyme) Leaf Oil)  is a blend of natural antimicrobial actives.

Both are said to be effective against Staphylococcus aureus (Gram-positive bacteria) at 0.5%, Escherichia coli (Gram-negative bacteria) at 0.5%, Candida albicans (yeast) at 0.5% and Aspergillus niger (filamentous fungi) at 1%. According to the company, the main difference between the two is the antioxidant efficacy; the Alpha product has an ORAC value of 4,349 ±1,202 (μmol TE/g), compared with the Beta product, with an ORAC value of 3,729 ±1,076 (μmol TE/g).

Both products are yellow in color  and have a characteristic and aromatic aroma. The two preservatives are recommended at 0.2–1.0% and have an optimum pH activity of 4.0–8.0. They are manufactured by super critical fluid extraction, selective fractionation and blending, and they are soluble in oils, fats and non-polar solvents.
