    Product Features & Efficacy
    1. High-Efficiency Hydration & Moisture Locking

    As a vital component of the skin's Natural Moisturizing Factors (NMF), PCA-Na possesses powerful hygroscopic and moisture-locking capabilities. It attracts moisture from the air and minimizes transepidermal water loss, offering significantly superior hydration compared to traditional humectants like glycerin and propylene glycol.

    2. Gentle, Skin-Friendly & Barrier Repair

    Highly compatible with human skin, it is mild and non-irritating. It enhances stratum corneum hydration, alleviates dryness, roughness, and flaking, and helps repair damaged skin barriers, making it ideal for formulations targeting sensitive and dry skin.

    3. Soft Skin Feel & Texture Enhancement

    It imparts a fresh, non-sticky sensation, leaving the skin soft, smooth, and free from tightness. It is widely used to elevate the sensory experience (skin feel) of skincare and personal care products.

    4. Antioxidant & Soothing Properties

    It assists in antioxidant protection and alleviates discomfort caused by external stressors, thereby improving the overall health of the skin.

    Frequently Asked Questions
    QWhat is PCA-Na (Sodium PCA) and where does it come from?
    Sodium PCA (PCA-Na) is the sodium salt of pyroglutamic acid, a naturally occurring component of the skin's Natural Moisturizing Factors (NMF). It is found naturally in human skin and plays a key role in maintaining optimal skin hydration levels.
    QWhat concentration of PCA-Na is available in this product?
    This product is supplied as a clear transparent liquid with an assay of 50%–55%, making it a concentrated and ready-to-formulate solution for cosmetic and personal care applications.
    QIs PCA-Na suitable for sensitive skin formulations?
    Yes. PCA-Na is highly compatible with human skin and is considered mild and non-irritating. It is particularly well-suited for formulations designed for sensitive, dry, or compromised skin types, as it helps repair the skin barrier and reduces dryness and flaking.
    QHow does PCA-Na compare to glycerin and propylene glycol as a humectant?
    PCA-Na offers significantly superior hygroscopic and moisture-locking capabilities compared to traditional humectants such as glycerin and propylene glycol. It effectively attracts moisture from the environment and minimizes transepidermal water loss (TEWL), providing longer-lasting hydration.
    QWhat types of products can PCA-Na be incorporated into?
    PCA-Na is highly versatile and can be used across a wide range of product categories including skincare (toners, serums, creams, masks), hair care (shampoos, conditioners), cleansing products (facial cleansers, body washes), and daily care items (body lotions, hand creams, baby care, aftershaves).
    QWhat are the recommended storage conditions for PCA-Na?
    PCA-Na should be stored sealed in a cool, dry place away from direct sunlight and heat sources. It is available in 25kg and 200kg drum packaging to accommodate both small-scale and large-scale production needs.
