R&D and Quality

Applications by Industry

Functional Beverages & Foods

Challenge: Water-based oxidation degrades colour and flavour.

Solution: This extract protects water-soluble vitamins against enzymatic browning. Usually 0.02-0.05% in drinks, 0.05-0.1% in sauces.

Ideal for:

· Energy drinks and herbal teas

• Blended fruit juices

• Fermented drinks

· Aqueous dressings and sauces

Functions as an antioxidant to extend shelf life without "preservative" label.

Cosmetics & Personal Care

Managing water-based serums' inherent preservation and product stability.

Antimicrobial and antioxidant characteristics limit synthetic preservative use.

Ideal for:

· Anti-aging serums

· Toners and mists

· Lightweight lotions

· Leave-on treatments

Benefit: It backs up claims of "clean beauty" and makes UV-protecting ingredient systems work better.

Supplements for nutrition

Problem: Getting effective amounts of rosmarinic acid into capsules that are easy to carry.

Answer: 50% standardisation of Rosemary Extract 50% Rosmarinic acid lets you give 200–500 mg doses per meal, which is the same as 100–250 mg of rosmarinic acid.

Ideal for:

· Cognitive support formulas

· Inflammation response supplements

· Liver health products

· Antioxidant complex blends

Benefit: Water-soluble format may enhance bioavailability versus oil-based extracts.
