Preservatives in MySkinRecipes Ingredients

Based on the information provided in the conversation:

• Double Hyaluron Liquid: This product is preserved with Phenoxyethanol at a concentration of 0.5% from the manufacturer.
• Panthenol (Vitamin B5) ExtraLite: This ingredient does not contain a preservative because it does not have a water component. The liquid form is due to its melting point being at room temperature.
• MOIST72 (Saccharide Isomerate): This product uses Citric Acid and Sodium Citrate as preserving agents. These are generally not considered conventional preservatives, allowing the product to be marketed as preservative-free.
• Sodium PCA and Potassium Azeloyl Diglycinate (Azelaic Acid): These ingredients do not contain added preservatives. The manufacturers state that the high concentration of the active ingredient in water prevents microbial growth.

Regarding the general principle of preservatives in liquid ingredients, the decision to include a preservative depends on whether the ingredient contains water. Ingredients without a water component typically do not require a preservative. However, manufacturers may sometimes add preservatives even if water is not present.
