    L-Carnitine Citrate CAS 62315-99-1

    L-Carnitine Citrate (CAS 62315-99-1) is a stable salt complex utilized as a premium nutritional ingredient in dietary supplements and functional beverages. Chemically formed by the ionic bonding of L-Carnitine with Citric Acid, this hygroscopic white powder functions to enhance the transport of fatty acids into mitochondria for energy production. As a highly soluble Carnitine derivative, it is extensively formulated into sports nutrition powders and weight management capsules to support lipid metabolism and exercise recovery. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific mesh size and purity requirements. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

    Product Description

    Carnitine Hydroxycitrate acts as a powerful active ingredient in body sculpting products. It is designed to penetrate the skin and assist in the metabolism of lipids.

    • Synergistic Effect: It combines L-Carnitine (known as the “fat transporter”) with Hydroxycitric Acid (a natural fruit acid derived from Garcinia Cambogia).
    • Stability: This salt form is chemically stable and less prone to absorbing moisture from the air compared to free L-Carnitine, ensuring a longer shelf life for finished cosmetic products.
    • Skin Benefits: Besides its potential slimming effects, it provides hydration and helps improve skin texture, leaving skin feeling smoother and firmer. It is fully water-soluble, allowing for clear formulations like gels and serums.

    Applications

    1. Body Slimming Products: The primary ingredient in “fat-burning” creams, lotions, and gels designed to reduce the appearance of cellulite and contour the body.
    2. Firming Lotions: Used in post-pregnancy or weight-loss skin care products to help tighten and firm loose skin.
    3. Sports Gels: Applied topically before workouts to enhance local circulation and metabolism.
    4. Facial Care: Occasionally used in V-shape face lifting serums due to its tightening properties.

    Usage Level: Typically recommended at 1.0% – 5.0% in the water phase of the formulation.

    Storage Conditions

    • Moisture Control: Although more stable than pure Carnitine, it is still sensitive to humidity. Store in a strictly dry environment.
    • Temperature: Store in a cool place (below 25°C), away from direct sunlight and heat sources.
    • Packaging: Keep inner liners tightly sealed immediately after use.
    • Shelf Life: 24 months under proper storage conditions.

    Safety Precautions

    • Skin Compatibility: Generally considered safe and mild for topical use. However, avoid using on broken or irritated skin.
    • Handling: Wear a dust mask and protective gloves during manufacturing to avoid inhalation of powder or direct eye contact.
    • Eye Contact: If powder enters eyes, rinse thoroughly with clean water for at least 15 minutes.
    • Ingestion: While components are food-grade, this specific raw material specification is for external cosmetic use. Do not ingest directly.

    FAQ - Technical & Supply Chain

    • Q:

      How is L-Carnitine Citrate CAS 62315-99-1 chemically distinguished from pure L-Carnitine?

      A: L-Carnitine Citrate (CAS 62315-99-1) is a reacted salt form that combines L-carnitine base with citric acid to improve stability and taste profile compared to the highly hygroscopic pure base.
    • Q:

      Is this ingredient suitable for beverage applications?

      A: Yes, this material is typically applied in functional drinks and liquid shots due to its excellent water solubility and pleasant acidic taste, which masks the fishy odor often associated with carnitine base.
