Formulation Review: Skin Barrier Repair and Oil Control Lotion

Ingredient Resolution & Classification

I have reviewed your formula and matched the ingredients with the MySkinRecipes catalog:

• Found: Glycerin, Propanediol, Ceracare™ Liposome-3, Panthenol (Vitamin B5), Disodium EDTA, ActiveProtec™ OX, Sebum-Reg™, Hyaluronic Acid (Standard Molecule), HydroAlgae™, Hi-LiconeA™, Prebio-care, Safe-B3™ (Vitamin B3), ActiveProtec™ UV, Portulaca Extract, Allantoin, Silk Lotion Maker, Sucrose Cream Maker™, Hydrogenated Coco-Glycerides (34C), Protec™ OX, Protec™ UV, Rosehip Oil, Squalane (Olive), Vitamin E (Tocopheryl Acetate), Xanthan Gum.
• Not Found: Super fruit oil (Replacement: Sea Buckthorn (Fruit) Oil (Virgin, CO2 Extraction). This is an excellent "super fruit" oil alternative, rich in vitamins and antioxidants, providing a similar high-nutrient profile for your oil phase).

Formula Review & Technical Recommendations

Your formula is well-designed, offering a comprehensive approach to skin barrier repair, oil control, and stability. However, there are critical technical steps required for these specific ingredients to work effectively:

1. Solubility & Preparation

• Sebum-Reg™ (Capryloyl Glycine): This ingredient has specific solubility requirements. In Part C, you must adjust the water pH to higher than 7 (using an alkalizer like Triethanolamine) to dissolve it completely. Once dissolved and mixed into the final formula, you should adjust the pH back down to 5.0–6.0, which is the range where it functions best.
• Hi-LiconeA™ (Licochalcone A): Your plan to create a 10% stock solution in Butylene Glycol is correct. This ingredient is not water-soluble but dissolves well in glycols. Using it at 1% of the stock (0.1% active) is the ideal rate for reducing oiliness and irritation.
• Ceracare™ Liposome-3: Dispersing this in the Glycerin/Propanediol phase (Part A) with slight heat (approx. 50°C) will ensure the liposomes are well-distributed before adding to the water phase.

2. Temperature Management

• HydroAlgae™: This is highly heat-sensitive. Do not exceed 40°C. It must be added in Part D only after the emulsion has cooled down to room temperature to preserve its moisture-retaining properties.
• Emulsification (Part E & F): Since you are using Hydrogenated Coco-Glycerides and Sucrose Cream Maker™, you must heat both the water phase and the oil phase to 70–80°C to properly melt the waxes and form a stable emulsion. Silk Lotion Maker can be used in cold processes, but in this specific formula, heat is required for the other structural components.

3. Stability & pH

• pH Control: Your target pH of 5.0–6.0 is perfect. It ensures the stability of Vitamin B3 (preventing conversion to nicotinic acid), Vitamin B5, and the efficacy of Sebum-Reg™.
• Protection System: You have implemented a very robust protection system. The combination of ActiveProtec™ OX/UV (water-phase) and Protec™ OX/UV (oil-phase) will effectively prevent the natural oils (Rosehip, Squalane, and Sea Buckthorn) from oxidizing and protect the botanical extracts from UV degradation.

4. Texture & Consistency

• Xanthan Gum: At 0.5%, this will provide good stability to the emulsion and a smooth skin feel.
• Allantoin: 0.2% is a safe and effective level that will dissolve easily in the water phase.

Overall, this is a professional-grade formulation. The most critical steps for success are the pH-dependent dissolution of Sebum-Reg™ and ensuring HydroAlgae™ is added only when the mixture is cool.
