Formula Review for Micellar Shower Gel

Let's review the formula you provided for a micellar shower gel:

• Sodium Coco Sulfate (12%): This is an anionic surfactant that provides cleansing and lather. While effective, it can be more stripping than the milder surfactants typically found in micellar products. The high percentage here suggests it will contribute significantly to foaming and cleansing power, potentially making it feel more like a standard shower gel.
• Ethylene Diamine Tetra Acetic (0.1%): This is likely Disodium EDTA, a chelating agent. It helps to bind metal ions in water, improving formula stability and preventing issues like soap scum. The concentration is appropriate.
• Propylene Glycol (5%): This acts as a humectant and solvent, helping to retain moisture in the skin and dissolve other ingredients. The usage rate is within the typical range.
• Polyglyceryl-4 Caprate (5%): This is a gentle non-ionic surfactant often used in micellar cleansers for its ability to effectively dissolve oils and makeup without being harsh. This ingredient supports the "micellar" claim.
• Sodium Hyaluronate (5%): This is a humectant known for its moisturizing properties. If this refers to a Hyaluronic Acid Gel Base, 5% is a reasonable amount to add hydration.
• Megacare Ph.D. (1%): I could not identify this ingredient. Its function in the formula is unknown.
• Hydroxypropyl Methylcellulose (1.5%): This is a non-ionic thickener that also helps stabilize foam. The concentration is suitable for creating a gel texture.
• Polyoxyethylene Monoalkyl ether phosphates (3%): I could not identify this specific compound. It is likely a surfactant or emulsifier, but its exact properties and contribution to the formula's mildness and micellar properties are unknown.
• Sodium Chloride (3%): This is commonly used to increase the viscosity of surfactant systems, helping to thicken the shower gel.
• Deionized water (64.4%): The base of the formula.

Overall Assessment:

The formula contains ingredients suitable for a shower gel, including surfactants for cleansing, thickeners for gel consistency, and humectants for moisturizing. The inclusion of Polyglyceryl-4 Caprate contributes to the micellar concept, providing gentle cleansing properties.

However, the relatively high concentration of Sodium Coco Sulfate, an anionic surfactant, might result in a product that feels more like a conventional foaming shower gel rather than a very gentle micellar cleanser, which typically uses milder surfactant systems. The effectiveness as a micellar shower gel specifically depends on the interaction of all surfactants and their ability to form micelles that effectively capture impurities.

The presence of unidentified ingredients (Megacare Ph.D. and Polyoxyethylene Monoalkyl ether phosphates) makes a complete evaluation challenging.

To enhance the micellar feel and mildness, you might consider adjusting the surfactant blend, potentially reducing Sodium Coco Sulfate and incorporating more mild co-surfactants.
