Aloe Vera Gel Formulation

1. Choosing a Gel Thickener

For creating an aloe vera gel using a cosmetic-grade extract, suitable thickeners include synthetic polymers. You mentioned Pro Polymer (Acrylates/C10-30 Alkyl Acrylate Crosspolymer), which is a common and effective choice for creating clear gels. Another option is Allianz OPT (Acrylates/C12-22 Alkyl Methacrylate Copolymer), which is also suitable for gels and can provide water resistance. These types of thickeners are widely used in cosmetics to achieve the desired gel texture.

2. Adding Vitamin E

To incorporate Vitamin E into your gel, you would typically use a cosmetic-grade form like Vitamin E (Tocopheryl Acetate) or Vitamin E (dl-alpha tocopherol). Vitamin E acts as an antioxidant, helping to protect the formulation from degradation and offering potential benefits to the skin. Ensure you use a form compatible with your gel base (usually water-soluble or dispersible if your gel is water-based). Vitamin E (Tocopheryl Acetate) is a stable and commonly used form.

3. Simple Formula for Home Use

A simple formula using cosmetic-grade Aloe Vera Extract, a thickener, and Vitamin E is a good start. However, even for home use and storage in the refrigerator, it is highly recommended to include a preservative. Water-based formulations are prone to microbial growth (bacteria, yeast, mold) once opened and exposed to air. Refrigeration slows this down but does not stop it entirely. Without a preservative, your gel could become contaminated within days, posing a risk of skin irritation or infection.

4. Preserving for Commercial Business

For commercial sale, a robust and effective preservation system is absolutely mandatory. You need a broad-spectrum preservative that is effective against bacteria, yeast, and mold and is compatible with your formula's pH and ingredients. An example of a suitable broad-spectrum preservative is Mild Preserved™ COS (Phenoxyethanol (and) Chlorphenesin (and) Caprylyl Glycol), which works in a wide pH range (2-8) and is water-soluble. Choosing the right preservative and performing challenge testing are critical steps before selling any cosmetic product.

In summary, while your goal of using natural ingredients is great, for safety and stability in cosmetic gels, opt for cosmetic-grade extracts and ingredients. Always include a suitable preservative, even for personal use, to ensure the product remains safe and effective.
