Core Benefits & Formulation Advantages

1. Superior Hydration & Moisture Retention
   As an effective humectant, Butylene Glycol helps attract and retain moisture in the skin, thereby enhancing the long-lasting hydrating effect of creams, lotions, and serums.

2. Excellent Solubilizer & Stability Enhancer
   It acts as a powerful coupling agent. For instance, it effectively dissolves various essential oils, plant extracts, and active ingredients, improving their compatibility and stability within the formulation to prevent separation or crystallization.

3. Optimizes Product Texture & Clarity
   Due to its low viscosity and clarity, it is ideal for creating lightweight, non-greasy serums, clear gels, and toners without compromising transparency.

4. Versatile & Wide-Ranging Compatibility
   This ingredient exhibits excellent compatibility with a broad spectrum of cosmetic ingredients, simplifying formulation processes and enhancing the performance of other functional agents.

Primary Applications in Formulations

• Skincare: Serums, Toners, Moisturizing Creams & Lotions, Facial Masks (to enhance active ingredient delivery and hydration).

• Hair Care: Conditioners, Styling Gels (to provide light conditioning and improve ingredient solubility).

• Oral Care: Toothpaste (as a humectant to maintain paste consistency and moisture).

• Fragrances & Essential Oils: Serves as an effective solvent.

Typical Usage Guidelines

• Recommended Dosage: 2.0% – 10.0%, depending on the specific formulation requirements and desired function.

• It can be easily incorporated into the water phase during the standard manufacturing process.
