I have several questions regarding cosmetic formulation and product information: * **Ingredient Compatibility:** * Which sulfur compounds are compatible with `Bakuchiol`? * Which sulfur compounds are considered electrolytes? * Which sulfur compounds are suitable for low-irritation acne treatment formulations, minimizing the risk of irritation or allergic reactions? * **Formulation Concentration and Irritation:** * Is using 20% active ingredients with 8 different actives generally considered too high, or does it depend on the specific formulation? * Does `4-Hexylresorcinol` cause irritation, as some external sources suggest? * When irritating ingredients like `Salicylic Acid` or other `salicylic acid` group substances are used with `DMI` or other penetration enhancers, will it increase irritation? * Does `Niacinamide` at 4% combined with `Acetyl Glucosamine` still retain its oil-controlling properties for the face? * **Texture and Sensory Properties:** * Is there comparative information available on the skin feel of emollient esters, specifically comparing `Propylene Carbonate` and `Lipidsoft Lite` regarding their lightness, slipperiness, and ease of spreading? Or is self-experimentation the best approach? * **Information Resources & Feedback:** * Are there recommended external cosmetic information sources beyond MySkinRecipes website and scientific journals? * How can I report incorrect or potentially misleading information on product detail pages (e.g., conflicting data, inclusion of food-related benefits for cosmetic products, broken document links, etc.)? Can I provide feedback or suggest additional missing details?

I want to create a modern cream with Shea Butter that is non-sticky, leaves no white cast, and absorbs quickly. I'm aiming for a cream-jelly texture that is bouncy like yogurt, feels lightweight and comfortable on the skin, but still looks dense and beautifully whipped like whipped cream. It should apply smoothly and allow active ingredients to penetrate the skin well. To achieve this texture, the formulation needs to combine a water phase, an oil phase, and a gel phase. I have the following questions regarding the formulation: * Which gelling agent should I choose? For example, can I use `Carbomer`? * How can I ensure compatibility with the pH of the active ingredients, which include `Vitamin C` (Ascorbic Acid), `Niacinamide`, `Kojic Acid`, `Alpha Arbutin`, `Tranexamic Acid`, and a small amount of soothing agents and `Mulberry Extract`? * What percentage of water and oil should I use to create this specific cream texture, especially when incorporating high, full dosages of the mentioned active ingredients? How can I formulate this product?

I am formulating a BB cream and have encountered an issue with the texture.
