Description and Key Features

Hydrolyzed Walnut Shell Protein is a cutting-edge cosmetic ingredient derived from the outer shell of walnuts, a source rich in natural proteins, antioxidants, and beneficial compounds. Through hydrolysis, these proteins are broken down into smaller, more bioavailable peptides, allowing for better absorption and efficacy in cosmetic formulations. Its light to light yellow liquid form and water solubility ensure easy integration into aqueous phases of your products.

Key features include:

• Italian Quality: Sourced from Gerard's Cosmetics, Italy, guaranteeing a high standard of purity and performance.
• Water-Soluble: Easily disperses in water-based formulas, making it suitable for a wide range of cosmetic applications.
• Optimal pH Range: With a pH between 5.0-6.5, it's compatible with most skin and hair care formulations, minimizing the need for extensive pH adjustment.
• Rich in Bioactive Compounds: Contains hydrolyzed proteins, which can help strengthen the skin's barrier, provide hydration, and offer antioxidant protection.
• Temperature Sensitivity: Crucially, this ingredient should not be heated above 40°C to maintain its active properties and ensure maximum effectiveness.

Versatile Applications and Usage Areas in Cosmetics

Hydrolyzed Walnut Shell Protein is a multi-functional ingredient, making it an excellent choice for a diverse range of cosmetic products. Its benefits extend across skincare, hair care, and specialized treatment formulas:

• Skincare for Face and Body:
  • Active Masks & Body Creams (4-5% inclusion): For intensive treatments, its high concentration provides profound moisturizing, nourishing, and protective effects, helping to restore skin vitality.
  • Daily Moisturizing Care (2% inclusion): Ideal for everyday lotions, serums, and creams, offering consistent hydration and strengthening the skin's natural barrier against environmental stressors.
  • After-Sun Skin Care (1.5-2% inclusion): Its soothing and hydrating properties make it perfect for formulations designed to comfort and replenish skin after sun exposure, reducing redness and dryness.
  • Healing Formulas, Serums, and Diathesis Cream (3-5% inclusion): In targeted treatments, it promotes skin recovery, soothes irritation, and supports the natural healing process, making it suitable for sensitive or compromised skin conditions.
• Hair Care Products:
  • Pigment Retention Hair Care (1-1.5% inclusion): Uniquely beneficial for hair products aimed at preserving color. The hydrolyzate can help protect hair pigments from fading, extending the vibrancy of dyed hair.
  • Vitaminizing Sprays (1% inclusion): Perfect for lightweight leave-in sprays that provide a boost of nutrients to the hair and scalp, promoting overall hair health and shine without weighing it down.

Important Note on Usage:

• Always add Hydrolyzed Walnut Shell Protein to the cool-down phase of your formulations, ensuring the temperature is below 40°C to prevent degradation of its active compounds. This is especially crucial for emulsions (creams, lotions) where a hot oil phase is initially required. For cold-process formulas (toners, serums), simply incorporate it into the water phase.

This versatile ingredient is suitable for formulators worldwide seeking high-quality, plant-derived components that deliver tangible benefits in their cosmetic creations.

Cosmetic Recipe: "Sunset Soothe" After-Sun Hydrating Lotion

Create a soothing and hydrating lotion perfect for after-sun care, featuring Hydrolyzed Walnut Shell Protein to nourish and protect skin.

Instructions for Preparation:

1. Sanitization: Thoroughly sanitize all your equipment (heat-resistant beakers, stirring rods, containers) using isopropyl alcohol. Allow everything to air dry completely.
2. Prepare Phase A (Water Phase): In a heat-resistant beaker, combine distilled water and glycerin. Heat on a double boiler to 70-75°C (158-167°F).
3. Prepare Phase B (Oil Phase): In a separate heat-resistant beaker, combine emulsifying wax, shea butter, sweet almond oil, and cetyl alcohol. Heat on a double boiler to 70-75°C (158-167°F), ensuring all solid ingredients are fully melted.
4. Emulsification: Carefully pour the hot water phase (Phase A) into the hot oil phase (Phase B) while continuously mixing with a hand mixer or immersion blender on low speed. Continue mixing until a smooth, uniform emulsion forms. The emulsion will thicken as it cools.
5. Cooling Down: Continue stirring the emulsion periodically until it cools down to below 40°C (104°F). This is crucial for adding heat-sensitive ingredients.
6. Add Phase C (Cool-Down Ingredients): Once the lotion is below 40°C, add the Hydrolyzed Walnut Shell Protein, broad-spectrum preservative, Vitamin E, and any optional essential oils or fragrance oils. Stir thoroughly until all ingredients are fully incorporated and the lotion is uniform.
7. pH Check (Recommended): Check the pH of your finished lotion. For body lotions, a pH between 5.0 and 6.0 is generally ideal for skin compatibility and preservative efficacy. Adjust if necessary using a diluted solution of lactic acid (to lower pH) or baking soda solution (to raise pH), adding drop by drop and rechecking.
8. Packaging: Transfer the finished lotion into a clean, sterile pump bottle or jar.

Recommendations for Use:

• Heat Sensitivity: Always adhere to the "do not heat above 40°C" instruction for Hydrolyzed Walnut Shell Protein. Add it only in the cool-down phase to preserve its beneficial properties.
• Usage Rate: For after-sun care, a 1.5-2% inclusion of Hydrolyzed Walnut Shell Protein is recommended, as used in this recipe. Adjust based on desired efficacy.
• Consistency: The protein hydrolyzate is a light liquid, so it won't significantly affect the final consistency of your lotion.
• Storage: Store the finished lotion in a cool, dark place, away from direct sunlight, to maintain the stability and efficacy of all ingredients.
• pH Stability: While the pH of the hydrolyzate is 5.0-6.5, always check the pH of your final product as other ingredients can influence it.
• Compatibility: Hydrolyzed Walnut Shell Protein is water-soluble and generally compatible with most common cosmetic ingredients.
