Optiphen Plus
Optiphen Plus is a liquid, broad-spectrum preservative used in cosmetics and personal care products to prevent microbial growth, including bacteria, yeast, and mold. It is paraben- and formaldehyde-free, making it a popular choice for clean beauty formulations. It’s designed for products with slightly acidic pH (below 6.0) but can be effective at higher pH levels depending on the formulation. Optiphen Plus extends shelf life and ensures product safety, particularly in water-based or emulsion-type formulations.
What is it Made of?
Optiphen Plus consists of:
-
- Phenoxyethanol: An aromatic ether alcohol that acts as a preservative, effective against bacteria and some fungi.
- Caprylyl Glycol: An emollient and humectant that enhances preservation, improves skin feel, and provides moisturizing benefits.
- Sorbic Acid: A natural acid derived from the mountain ash tree, offering protection against yeast, mold, and some bacteria. This combination provides broad-spectrum protection while imparting emollience, making it a multifunctional ingredient.
Best Skin Type for Using It:
Optiphen Plus is suitable for all skin types, particularly:
-
- Oily and Acne-Prone Skin: Its antimicrobial properties help prevent bacterial growth, which can exacerbate acne, and its non-comedogenic nature avoids pore clogging.
- Dry Skin: Caprylyl glycol adds hydration and a smooth feel, benefiting dry or dehydrated skin.
- Normal and Combination Skin: Its balanced preservation and emollient properties maintain product stability without disrupting skin’s natural balance.
- Sensitive Skin: Its non-irritating, paraben- and formaldehyde-free formula is gentle, with low sensitizing potential, making it ideal for those prone to allergies.
- Mature Skin: The moisturizing and non-irritating qualities support aging skin’s needs. However, individuals with extremely sensitive skin should patch-test, as rare reactions to phenoxyethanol or sorbic acid have been reported.
