Sodium Pyrrolidone Carboxylic Acid (NaPCA)

Sodium Pyrrolidone Carboxylic Acid (NaPCA) is a naturally occurring amino acid derivative and a highly effective humectant used in personal care and cosmetic products. It is known for its excellent moisture-binding properties, making it an ideal ingredient for hydration-focused formulations. Sodium PCA is the sodium salt of pyrrolidone carboxylic acid, derived from natural sources like vegetable proteins.

Key Benefits:

1. Moisturizing and Hydrating:
   • Acts as a powerful humectant that attracts and retains moisture in the skin, leaving it feeling hydrated and soft.
   • Helps to improve skin elasticity and prevent dryness by binding moisture to the skin surface.

   • Provides a smooth, velvety feel to the skin without being greasy, making it ideal for use in lotions, creams, and body care products.
3. Compatible with Sensitive Skin:
   • Gentle and non-irritating, making it suitable for sensitive skin and baby care formulations.
4. Improves Skin Barrier Function:
   • Enhances the skin’s natural moisture barrier, preventing transepidermal water loss (TEWL) and protecting against environmental factors.
5. Versatile in Formulations:
   • Works well in both anhydrous and aqueous formulations, including gels, serums, moisturizers, and shampoos.
   • Enhances the performance of other active ingredients by improving their penetration and stability.
6. Non-Comedogenic:
   • Does not clog pores, making it suitable for acne-prone or oily skin formulations.

Applications:

1. Skin Care:
