Provital Debuts Kromboost™: Upcycled Barley Active Targets Hair Longevity and Fiber Integrity

Botanical active specialist Provital has launched Kromboost™, a biotechnology-derived bioactive upcycled from barley malt rootlets—an abundant byproduct of the malting and brewing industry. The ingredient targets two primary drivers of daily hair degradation: mechanical fiber failure and rapid color fading. In markets like India, where consumers deal with hard, mineral-heavy tap water, heat styling, and intense UV exposure, this upcycled protein offers R&D teams a science-backed tool for structural hair longevity.

Biomimetic Chemistry and Active Profile

Kromboost™ relies on a concentrated phytocomplex rich in functional bio-peptides, polyphenolic antioxidants, and a high concentration of L-serine. Thanks to its low-molecular-weight peptide profile, the ingredient demonstrates high binding affinity for damaged keratin across both the outer cuticle and the internal cortex.

Cuticle Scale Repair: The bio-peptides coat damaged keratin zones, forming a cohesive biomimetic film along the hair shaft. This smoothes lifted cuticle scales, reduces surface friction, and restores the hydrophobic barrier needed to maintain optimal moisture levels.

Cortical Cross-Linking: L-serine penetrates into the cortex to reinforce hydrogen bonding networks. This structural support buffers native disulfide bonds against chemical breakdown and thermal degradation during heat styling.

Antioxidant Dye Protection: Polyphenols neutralize reactive oxygen species (ROS) induced by UV exposure, preventing free radical oxidation from breaking down dye molecules inside the fiber core.

Ex Vivo Bench Testing: Fast-Acting Fiber Protection

To evaluate performance in quick-application formats, Provital conducted ex vivo testing using a 2% Kromboost™ concentration in a 3-minute rinse-off system. The results demonstrated immediate mechanical and aesthetic benefits compared to untreated hair tresses:

Breakage Resistance: Improves fiber breakage resistance by 152% under repeated mechanical stress compared to untreated controls.

Color Longevity: Increases artificial color retention by 166%, preventing premature shade washout across multiple shampoo cycles.

These short-contact metrics give bench formulators concrete data to support high-performance claims in rinse-off applications like express conditioners and post-treatment masks.

Bench Guidance and Processing Parameters

Kromboost™ is a brown, water-soluble liquid that integrates cleanly into standard cold-process manufacturing workflows without requiring specialized equipment or solubilizers.

Recommended Usage Level: 0.5% to 2.0% depending on product positioning and targeted claim depth.

Processing Conditions: Add directly to the aqueous phase or during the cool-down phase below 45°C in hot-emulsified systems.

pH Working Range: Remains stable across pH 4.0 to 7.0, allowing easy incorporation into acidic post-color sealers as well as neutral leave-in treatments.

Compatibility: Fully compatible with common non-ionic, anionic, and cationic conditioning agents, as well as typical preservation systems.

Regulatory Positioning for Indian Manufacturers

For Indian brand owners and contract manufacturers operating under the *Drugs and Cosmetics Rules, 2020*, Kromboost™ presents a clear regulatory path:

CDSCO Classification: Classified as a standard cosmetic ingredient. Finished products containing the active do not require specialized drug licensing for domestic production or sale.

Import Requirements: Requires standard customs documentation, including a detailed Certificate of Analysis (COA) and Safety Data Sheet (SDS).

Global Compliance: The active is COSMOS-approved, non-GMO, and ISO 16128 compliant with a high Natural Origin Index, giving formulators an effortless route to clean-label positioning.

By combining upcycled circular chemistry with verified tensile and color-protection data, Provital offers formulators a reliable foundation for next-generation hair longevity products.
