ShieldBiso™ IMC: The Synergy Booster for Next-Gen Suncare

Stop choosing between SPF performance and formulation stability. With ShieldBiso™ IMC, you get both.

In the pursuit of effective sun protection, formulators constantly face challenges: maintaining high efficacy while ensuring ingredient compatibility and long-term stability. ShieldBiso™ IMC (Isoamyl p-Methoxycinnamate) is engineered to overcome these limitations.

The Power of Synergy 

The core advantage of ShieldBiso™ IMC lies in its ability to amplify the efficacy of existing systems. Combining IMC and OMC in a single formula produces a superior synergistic efficiency, allowing formulators to achieve higher SPF at optimized active loadings.

Beyond UV Absorption: The Stability Enhancer

ShieldBiso™ IMC is far more than a standard UVB filter. It is the only sunscreen agent known to occur in nature, and its synthetic form matches the quality of its natural counterpart — making it the natural equivalent of sunscreens.

Key formulation advantages include:

Excellent Solvent Capacity: IMC demonstrates strong solubility for crystalline and oil-soluble UV absorbers. It effectively dissolves solid filters including Butyl Methoxydibenzoylmethane (20%), Benzophenone-3 (26%), 4-Methylbenzylidene Camphor (25%), Ethylhexyl Triazone (34%), and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (35%), preventing recrystallization and ensuring long-term product stability.

Precise Spectral Coverage: With a peak absorptivity at 308 nm, ShieldBiso™ IMC precisely targets the UVB band, partially covers UVA-II, and completely avoids UVA-I, making it an essential UVB absorber for broadband and water-resistant formulations.

Process Friendly: The ingredient is easily emulsified, fully photostable, and suitable for cold-processing, reducing manufacturing complexity.

Skin Compatibility: Backed by comprehensive safety studies, ShieldBiso™ IMC offers excellent skin compatibility for daily use.

Technical Excellence

ShieldBiso™ IMC is a clear, colorless to pale yellow liquid with a characteristic odor. Each batch undergoes rigorous quality control testing. A recent batch (BIMC240723) achieved a GLC purity of 99.2% with a specific extinction of 1039 at 307-308 nm. The product maintains a relative density of 1.038-1.040 and a refractive index of 1.5560-1.5600, ensuring consistency across production runs.

Nature-Identical & Globally Compliant 

ShieldBiso™ IMC holds a unique position in the market as the only UVB filter found in nature. Our synthetic IMC is chemically identical to the natural compound, perfectly aligning with the growing demand for nature-identical ingredients.
