We’re pleased to announce the addition of a new water-soluble rosemary extract specification to our supply network. The new grade, standardized to Carnosic Acid 10% and engineered for clear dissolution in aqueous systems, addresses a long-standing formulation challenge for beverage, gummy, and liquid supplement manufacturers.

Standard oil-soluble rosemary extract doesn’t dissolve in water—it forms visible oil droplets, hazing, or phase separation. The new water-soluble grade eliminates these issues through a proprietary carrier technology that delivers carnosic acid in a fully water-dispersible powder.

Why We Developed a Water-Soluble Rosemary Extract

Over the past 18 months, we’ve received repeated inquiries from buyers in three application areas:

Clear beverages: RTD drinks, functional waters, ready-to-mix sachets, effervescents
Gummies and chews: Fruit-flavored gummies, chewable supplements, jelly candies
Liquid supplements: Drops, syrups, liquid shots, liquid-filled capsules

For all of these, standard oil-soluble rosemary extract is unsuitable. Buyers were either:

  • Using water-soluble alternatives with lower carnosic acid content
  • Attempting to formulate with oil-soluble grades and accepting hazy or unstable products
  • Skipping rosemary extract entirely despite its functional benefits

    • The new water-soluble grade addresses this gap with a specification designed specifically for aqueous applications.

    Technical Specifications

    | Parameter | Specification | Method |

    |—|—|—|

    | Carnosic Acid | ≥ 10.0% | HPLC |

    | Rosmarinic Acid | ≥ 3.0% | HPLC |

    | Appearance | Light yellow to yellow-brown powder | Visual |

    | Moisture | ≤ 5.0% | Loss on drying |

    | Bulk Density | 0.4–0.6 g/mL | Tapped |

    | Water Solubility | Fully dispersible, clear to slightly hazy solution at 1% | Visual |

    | Particle Size | 95% pass 80 mesh | Sieve analysis |

    | Heavy Metals (Pb/Cd/As/Hg) | ≤ 3 / ≤ 1 / ≤ 1 / ≤ 0.1 ppm | ICP-MS |

    | Total Plate Count | ≤ 1,000 CFU/g | Plate count |

    | Yeast & Mold | ≤ 100 CFU/g | Plate count |

    | E. coli / Salmonella | Negative | Standard methods |

    Carrier system: Food-grade cyclodextrin complexation (typically beta-cyclodextrin) or proprietary polysaccharide-based carrier. Specific carrier available on request and varies by supplier.

    Target Applications

    Ready-to-drink (RTD) beverages:

  • Functional waters with antioxidant positioning
  • Energy drinks and wellness shots
  • Plant-based beverage formulations
  • Sports recovery drinks

    • Gummies and chews:

  • Adult supplement gummies (especially antioxidant blends)
  • Functional confectionery
  • Chewable supplement tablets

    • Effervescent products:

  • Effervescent tablets and powders
  • Drink mixes and stick packs
  • Hot and cold instant beverages

    • Liquid supplements:

  • Liquid drops and tinctures
  • Liquid-filled capsules (softgel)
  • Functional syrups

    • Cosmetic aqueous formulations:

  • Toners and mists
  • Aqueous serum formulations
  • Sheet mask essences

    • Formulation Tips and Stability Data

    Recommended inclusion rates:

  • Beverages: 0.05%–0.2% (delivers 50–200 ppm carnosic acid in finished product)
  • Gummies: 0.1%–0.3%
  • Effervescent tablets: 50–200 mg per tablet
  • Liquid supplements: 0.05%–0.1%

    • pH considerations:

  • Most stable at pH 4–7
  • Avoid strongly acidic (pH < 3) formulations as carnosic acid degrades
  • Adjust with appropriate buffering if needed

    • Heat processing:

  • Avoid temperatures above 70°C during formulation to preserve carnosic acid
  • For hot-fill applications, add rosemary extract post-pasteurization if possible
  • For baked or cooked applications, carnosic acid will partially degrade—rely on other natural antioxidants

    • Storage:

  • Finished products: opaque or amber packaging to protect from light
  • Bulk extract: sealed, dry, below 25°C
  • Shelf life: 24 months in original packaging; verify with finished product stability testing

    • Sensory profile:

  • Significantly milder than oil-soluble rosemary extract
  • Light herbal note, less pungent
  • Compatible with most flavoring systems; verify with flavor testing for your specific formulation

    • Sample Availability and Lead Times

    Free samples (10–50g) are available for qualified B2B buyers. To request a sample:

  • Email us at ashley@nourishingr.com or submit the inquiry form
  • Provide your target application (beverage, gummy, etc.)
  • Specify your target inclusion rate and carnosic acid dose
  • We’ll ship samples within 48 hours with full COA

    • Production lead times:

  • Sample: 5–7 days
  • 25–100 kg trial order: 7–14 days
  • Full production run (500 kg+): 14–21 days

    • Pricing:

  • Higher than standard oil-soluble grades due to the additional carrier and processing
  • Contact us for current pricing based on volume and specification

    • Comparison to Standard Oil-Soluble Grades

    | Parameter | Standard (Oil-Soluble) | New Water-Soluble |

    |—|—|—|

    | Carnosic acid range | 5%–40% | 10% (current) |

    | Water solubility | Poor (oil droplets, hazy) | Fully dispersible |

    | Best for | Fats, oils, capsules, baked goods | Beverages, gummies, aqueous formulas |

    | Flavor impact | Strong, herbal | Mild, less herbal |

    | Cost per kg | Lower | Higher (carrier cost) |

    | Cost per dose | Comparable (lower inclusion rate) | Comparable (higher spec) |

    For finished product applications where standard oil-soluble rosemary extract doesn’t work, the new water-soluble grade is the practical solution. For applications where oil-soluble grades work fine (fats, capsules, baked goods), the standard grade remains more cost-effective.
