Vitamin C (3-Glyceryl Ascorbate)

Vitamin C

Use 5% to 20% in serums, creams, or lotions.

Lower concentrations (e.g., 5%) are suitable for sensitive skin products.1. Skincare Manufacturing

Vitamin C is highly valued in skincare for its brightening, anti-aging, and antioxidant properties.

Steps:

Choose the Right Form:

• Ascorbic Acid (L-AA): Highly effective but unstable; works best at pH 2.5–3.5.
• Stable Derivatives: Sodium ascorbyl phosphate, magnesium ascorbyl phosphate, or ascorbyl glucoside are suitable for more stable formulations.

Concentration:

• Use 5% to 20% in serums, creams, or lotions.
• Lower concentrations (e.g., 5%) are suitable for sensitive skin products.

Dissolution:

• Dissolve Vitamin C in water or glycerin, depending on the form used.
• Ensure proper mixing and dissolution to avoid graininess.

pH Adjustment:

• Maintain the formulation pH between 2.5 and 3.5 for ascorbic acid.
• Stable derivatives can tolerate a pH closer to neutral (5.0–7.0).

Combine with Stabilizers:

• Add ferulic acid, Vitamin E, or other antioxidants to enhance stability and efficacy.
• Use airless and opaque packaging to prevent oxidation.

2. Haircare Manufacturing

Vitamin C can be used in shampoos, conditioners, and hair masks for its antioxidant and scalp-nourishing benefits.

Steps:

1. Concentration: Use 0.5% to 3% for haircare formulations.
2. Incorporate During Water Phase: Add Vitamin C during the water phase and mix until fully dissolved.
3. Combine with Moisturizers: Pair with hydrating agents like panthenol or aloe vera to improve scalp health and hair texture.

3. Food and Beverage Manufacturing

Vitamin C is used as a preservative, flavor enhancer, and nutritional supplement in food and drinks.

Steps:

1. Form: Use food-grade ascorbic acid or its sodium salt (sodium ascorbate).
2. Concentration:

• Use as per regulatory guidelines for food products (e.g., 50–500 mg per serving).
• Add during mixing or blending to ensure uniform distribution.

4. Stabilization: Store in a cool, dry place to prevent degradation.

4. Pharmaceutical Manufacturing

Vitamin C is used in tablets, capsules, syrups, and injectables for its immune-boosting and antioxidant properties.

Steps:

1. Select the Right Form: Use pharmaceutical-grade Vitamin C or derivatives for stability.
2. Preparation: Dissolve Vitamin C in sterile water for injectables or syrups.
3. Dosage: Follow medical and regulatory guidelines for Vitamin C concentration in pharmaceutical products.
