Redefining Oral Care Through Science

The oral care industry has long lacked disruptive innovation. Leveraging decades of research, GBC introduces the P113 antimicrobial peptide, a breakthrough derived from the naturally occurring histatin-5 protein in human saliva.
With broad-spectrum antibacterial and antifungal properties, P113 selectively inhibits Streptococcus mutans and other oral pathogens, maintaining a healthy oral microbiome from the source.

Clinically Proven, Scientifically Validated

P113 is backed by clinical studies involving over 1,000 participants, demonstrating:
• Powerful antimicrobial efficacy — inhibits up to 90% of harmful oral bacteria
• Low allergenicity — safe for sensitive oral mucosa and skin
• Non-cytotoxicity — suitable for infants, pregnant women, and sensitive groups
• Globally recognized safety — data cited by international research institutions, aligning with global oral care standards

These findings make P113 a new-generation antimicrobial solution combining safety and efficacy.

Introducing the oh care® Oral Care Series

Through its subsidiary GB Pharma, GBC has transformed P113 technology into the oh care® consumer healthcare line, featuring:
• Gentle antimicrobial mouthwash
• On-the-go oral spray
• P113-powered toothpaste

The oh care® series embodies “Science × Safety × Daily Wellness”:
• Alcohol-free, fluoride-free formulations
• Free from preservatives, colorants, and artificial sweeteners
• Designed for all ages, including infants, pregnant women, and seniors


Beyond Oral Care: Expanding the Vision

The potential of P113 goes beyond oral health.
GBC is collaborating with research partners to explore applications in skin protection, mucosal care, and immune modulation, paving the way for next-generation consumer healthcare solutions.

Conclusion

P113 is more than an innovation — it’s a bridge between science and daily life.
By integrating P113 into the oh care® series, GBC sets a new benchmark for safe, effective, and science-driven oral care, embodying our vision:

“Bringing Science into Everyday Wellness.”
