# Formulation Challenge: Water-Based Essential Oil Pillow Spray I am formulating a water-based Essential Oil Pillow Spray using the following components: * Distilled Water * Essential oils (5%) * PEG-40 and Flora Solve™ Clear (Solubilizer ratio 3:1 relative to EO) * Fixative (5%) I encountered issues after adding the Fixative: 1. **Cloudiness:** When Fixative is added at 5%, the product becomes cloudy even when using a Solubilizer-to-EO ratio of 2:1 (which was clear before adding the Fixative). 2. **Viscosity:** Increasing the Solubilizer-to-EO ratio to 3:1 (with 5% Fixative) results in slight cloudiness, while a 4:1 ratio (with 5% Fixative) results in a clear product that is highly viscous. I need advice on the following: 1. How can I achieve a clear and non-viscous final product? 2. If I replace PEG-40 and Flora Solve™ Clear with `Polyglyceryl-6 Caprylate` and `Polyglyceryl-4 Caprate`, will this substitution yield a clear and non-viscous result? 3. What non-irritating substance can be used to effectively enhance scent diffusion and longevity?

# EasyThick™ Instability in Dishwashing Liquid Formulation I am formulating a dishwashing liquid using **EasyThick™ (PEG-90 Glyceryl Isostearate)** as the gelling agent. The initial process successfully formed a thick gel. However, during the final step of adding liquid fragrance and food coloring, the gel instantly collapsed and turned back into a liquid. 1. Is this instability caused by the food coloring or the liquid fragrance? 2. What specific types of liquid fragrance and color are compatible with `EasyThick™` to maintain viscosity? *Note: When testing with **HEC (Hydroxyethylcellulose)** as the gelling agent, adding fragrance and color only resulted in a slight drop in viscosity, not a complete collapse, unlike the result with EasyThick™.*

I am using a Stabilized Cellulase Enzyme (Alkaline type) which has an optimal activation range of pH 6-10 and temperature 25-60°C. I have two questions regarding its use in a concentrated liquid laundry detergent: 1. Can the finished concentrated liquid laundry detergent formula have a pH exceeding 10? Or must the detergent be maintained strictly within the specified pH range (6-10)? If the pH is slightly lower or higher than this range, will the enzyme be damaged, considering that dilution during washing should bring the pH back into the 6-10 range? 2. Does the concentrated formula require a preservative? If so, which type is recommended?
