Preventing Spoilage in Leaf Water Extract Spray

Water extracts from leaves are highly susceptible to spoilage and developing a foul odor because water is the main component, providing a good environment for microbial growth. Storing at room temperature accelerates microbial contamination and growth.

The way to prevent spoilage is to add a broad-spectrum preservative that is effective against various microorganisms and can be used in water-based products. This will inhibit the growth of bacteria, yeast, and mold.

Several suitable preservatives for water extracts that can be used in sprays include:

• PE 1090 Preservative: A commonly used preservative with broad-spectrum efficacy, inexpensive, works in a wide pH range, and is well-soluble in water at recommended usage rates (0.5-1.0%).
• Mild Preserved Eco™ (Preservative-Free): Effectively inhibits microorganisms, is gentle, non-irritating to the skin, and is not classified as a preservative by the FDA. It can be used in water-based formulas (recommended 1.0-1.5%).
• Coco-Preserve™ (Preservative from Coconut Extract): A natural preservative derived from coconut extract. It is directly water-soluble and provides broad-spectrum protection against bacteria, yeast, and mold (recommended 0.8-1.5%).

Additional Recommendations:

• Always use the preservative at the manufacturer's recommended rate and ensure compatibility with other ingredients in your formula.
• The extraction process should be as clean as possible to minimize initial microbial contamination.
• If you plan to produce for sale, a Challenge Test should be performed to confirm the effectiveness of the preservative in your specific formula.

Using a preservative will help extend the shelf life of your leaf water extract and prevent unpleasant odors, making it safe to use as a spray.
