Answer

Gel Formulation for Intimate Areas

Regarding your gel formulation for intimate areas, the ingredients included are generally used in cosmetic products. Ingredients like Allantoin and Panthenol are known for their soothing and moisturizing properties, which can be beneficial for sensitive skin.

However, for products intended for intimate areas, it is highly recommended to avoid ingredients that can cause irritation. Fragrance and colorants are common culprits for sensitivity in these areas. To minimize the risk of irritation, it would be best to omit the fragrance and color from this formula.

The inclusion of Ganoderma lucidum extract and Ginseng Extract can offer beneficial properties, but ensure the extracts used are suitable for cosmetic applications and properly incorporated into a water-based gel.

It is also crucial to ensure the final pH of the product is appropriate for the intimate area, which is typically slightly acidic (around pH 3.5-4.5). The pH should be checked and adjusted after all ingredients are added, especially considering the presence of Vitamin C and Triethanolamine.

Dissolving Vitamin E for a Clear Gel

You mentioned having Vitamin E (Tocopheryl Acetate) and wanting a clear gel. The standard Vitamin E (Tocopheryl Acetate) is oil-soluble. Adding an oil-soluble ingredient directly to a water-based gel will make it cloudy or opaque and may not dissolve properly.

To achieve a clear gel with Vitamin E, you should use a water-soluble version of Vitamin E, such as Vitamin E (Tocopheryl Acetate) Water-Soluble. This type is designed to dissolve directly in water-based formulations, allowing you to maintain the clarity of your gel.
