Toner Formulation Review and Usage Rates

Based on the ingredients you've listed, this formulation looks suitable for a toner. It includes hydrating components, soothing botanical waters and extracts, a mild cleansing agent, and a preservative system.

Here's a breakdown of the ingredients found in our database and their typical usage rates for cosmetic formulations like toners:

• Chamomile Water (Anthemis Nobilis) and Lavender Water (Lavandula Angustifolia): These are soothing and refreshing botanical waters. They can be used as the primary base for your toner, up to 100% of the formulation. Note that these waters already contain a preservative (Phenoxyethanol 0.8%).
• Glycerin: A humectant that helps attract and retain moisture in the skin. Typical usage rate is 1-10%. While it can be used up to 100%, it's not suitable for direct application at high concentrations.
• Sodium Hyaluronate (Small Molecule) and Double Hyaluron Liquid (contains Standard and Nano HA): These provide hydration to the skin. For Sodium Hyaluronate powder (Small Molecule), a typical usage rate is 0.1-0.5%. For Double Hyaluron Liquid, the recommended usage rate is 3-5% for normal/dehydrated skin, 5-10% for dry skin, and 10-20% for very dry skin.
• Polyglyceryl-4 Caprate: This acts as a mild solubilizer and cleansing agent, helping to disperse oils and remove impurities. A recommended usage rate is around 5%, but it can be used from 0.1% to 10%.
• Butylene Glycol: A solvent and humectant that helps improve the texture and stability of the formulation. Typical usage rate is 1-10%. It can be used up to 20%.
• Phenoxyethanol SA (eq. Optiphen Plus): A broad-spectrum preservative essential for preventing microbial growth in water-based formulations like toners. The recommended usage rate is 0.5-1.25%. Ensure your final pH is within the effective range (pH 2.0-6.0).
• Citric Acid: Used to adjust the pH of the formulation. Add small amounts gradually and measure the pH until the desired range (typically pH 5.5-6.5 for skin) is reached.
• Rose Geranium Oil (Flower): An essential oil that provides fragrance and potential skin benefits. Typical usage rate is 0.1-1.0%.
• Natural Bisabolol (Brazil Chamomile) (matched to Anthemis Nobilis Flower Oil): Known for its soothing and anti-inflammatory properties. Typical usage rate is 0.5-1%, with 1% recommended. It is oil-soluble.

Some ingredients you listed, such as Witch Hazel Water, Radish extract, Lotus stamen extract, Hippophae rhamnoides Fruit (Seaberry) Extract, Chlorella vulgaris Extract, and Glycolipids, were not clearly identified in our database searches. Therefore, I cannot provide specific usage rates or detailed information for these particular ingredients from our product catalog. If you are using these ingredients from another source, please refer to the supplier's recommended usage rates and compatibility information.

When formulating your toner, combine the water-soluble ingredients first, ensuring powders like Sodium Hyaluronate are fully dissolved (this may require time or gentle heating as per product instructions). Add oil-soluble ingredients like Natural Bisabolol and Rose Geranium Oil, potentially pre-dispersed in Polyglyceryl-4 Caprate or a small amount of Butylene Glycol if needed, depending on their solubility. Add the preservative (Phenoxyethanol SA) in the final step when the temperature is below 60°C and adjust the pH with Citric Acid.
