ViroBiome™ Shield
Augmented Hygiene Module
Lipid Barrier Reinforcement & Targeted Enzymatic Modulation
For functional hygiene, exposed interfaces and next generation nonwoven systems
Designed for urban exposure, aging sensitive tissues and high contact biological surfaces.
Why SHIELD Matters Now
Hygiene is entering a new phase.
Urban density, repeated contact, air pollution and demographic aging are increasing the pressure placed on exposed biological interfaces such as skin, mucosa and fragile barrier zones.
Conventional hygiene has mainly focused on removal, cleansing or elimination.
ViroBiome™ SHIELD introduces a complementary approach.
Reinforce. Modulate. Preserve.
It is designed to support the biological resilience of exposed surfaces while remaining compatible with microbiome friendly, non systemic and functional hygiene strategies.
Urban Exposure
High density environments expose skin and mucosal interfaces to:
• particulate pollution
• oxidative stress
• repeated friction and contact
• biological interface pressure
• daily environmental imbalance
In this context, biological surfaces are no longer passively exposed. They require reinforced and better organized surface protection.
Aging Sensitive Tissues
With age, exposed tissues may present:
• reduced lipid cohesion
• lower ceramide availability
• weakened barrier integrity
• altered microbiome balance
• increased susceptibility to inflammatory stress
Barrier fragility becomes structural rather than occasional.
This creates a clear need for hygiene technologies able to reinforce surface resilience without relying solely on aggressive elimination mechanisms.
Climate Warming
Climate warming adds a third systemic pressure on exposed biological interfaces.
Rising temperatures, heat waves, air pollution peaks, wildfire particles, longer pollen seasons and increased aeroallergen exposure may intensify daily stress on skin, mucosa and fragile epithelial zones.
Climate warming can contribute to:
• increased heat stress on exposed tissues
• higher oxidative pressure from pollution and wildfire particles
• longer and more intense allergen exposure
• greater skin and mucosal sensitivity during extreme weather events
• increased dehydration pressure on the epidermal barrier
• more frequent interaction between pollution, humidity, heat and biological surface imbalance
Together, urbanization, aging and climate warming create a structural need for hygiene technologies that do more than clean.
They must help exposed interfaces remain resilient in environments that are hotter, denser, more polluted and biologically more unstable.
What Is ViroBiome™ SHIELD?
ViroBiome™ SHIELD is a dual bioactive module combining two complementary plant derived technologies:
ViroBiome™ Safety = HTR1™
A patented non proteinic plant derived functional active designed for targeted enzymatic modulation and localized surface protection.
ViroBiome™ CERA
A rapeseed derived lipid fraction containing ceramides and associated membrane phospholipids, designed to support lipid barrier reinforcement, comfort and microbiome compatible surface balance.
Together, they create a biomimetic surface protection module for functional hygiene and exposed interfaces.
Core Functional Benefits
Local Functional Barrier
Supports the formation of a protective surface layer designed to reinforce biological interfaces exposed to environmental stressors.
Targeted Enzymatic Modulation
Designed to interact with selected enzymatic pathways involved in biological activation and interface stress mechanisms.
Lipid Barrier Reinforcement
Supports lipid cohesion, hydration comfort and surface barrier stability through rapeseed derived ceramides and associated membrane phospholipids.
Microbiome Compatible Balance
Designed to preserve beneficial microbial ecosystems by avoiding a broad biocidal positioning.
Reduced Exposure
Helps limit adhesion, persistence and surface imbalance at exposed biological interfaces.
Non Systemic Approach
Designed for localized action at the surface, with relevance for daily hygiene, dermal care and hygiene adjacent materials.
Scientific & Mechanistic Foundation
Surface Barrier Effect
In an ex vivo human skin explant model exposed to particulate matter, a Spray SV formula containing 2.5 % HTR1 reduced IL-6 production compared with the physiological saline control.
This supports a localized barrier effect against environmental particulate stress.
This result should be communicated as an ex vivo biological barrier finding, not as a clinical therapeutic claim.
Targeted Enzymatic Modulation
HTR1™ is positioned as a non proteinic plant derived functional active designed to modulate selected enzymatic pathways involved in biological activation processes.
This mechanism supports a scientific positioning around targeted surface modulation.
It does not constitute a direct clinical antiviral, antibacterial or therapeutic claim.
Rapeseed Lipid Barrier Support
ViroBiome™ CERA is based on a rapeseed derived lipid fraction containing ceramides and associated membrane phospholipids.
This supports a biomimetic positioning around lipid cohesion, barrier comfort, hydration support and resilience of exposed surfaces.
Microbiome Friendly Hygiene
ViroBiome™ SHIELD is not positioned as a disinfectant or a biocide.
It is designed as an augmentation layer for functional hygiene, supporting surface balance rather than indiscriminate microbial destruction.
Advanced Functional Architecture
Beyond its bioactive composition, ViroBiome™ SHIELD can be integrated into advanced compartmentalized surface architectures.
These architectures are designed to support:
• localized bioactive deposition
• controlled migration
• enhanced retention
• differentiated release
• separation of functional layers
• compatibility with nonwoven and hygiene materials
This creates a bridge between bioactive ingredients and industrial material design.
Potential formats include:
• functional nonwoven substrates
• bioactive coating systems
• advanced protective tissue technology
• treated wipes
• absorbent hygiene materials
• dermal sprays
• barrier creams
• gels and emulsions
• hygiene adjacent textiles
