THE MECHANISM

The Science Behind Bacteriostasis®

01
BACTERIO

Bacteria

Refers to bacteria that build up inside helmet padding, where sweat, moisture and heat create conditions for bacterial growth.

+
THE SCIENCE OF
BACTERIOSTASIS
®

Keeping bacterial growth
under control.

02
STASIS

To Hold / Keep Stable

Means slowing or holding bacterial multiplication rather than allowing the population to continuously increase.

Bacteriostasis® is the principle of keeping bacterial multiplication under control, helping prevent bacteria from reaching levels associated with unwanted odour and discomfort that may contribute to skin irritation.

ADVANCED HELMET HYGIENE SCIENCE

The Core Science Powering Hygena

BACTERIOSTATIC
Hygena Science
MICROBIAL CONTROL

Bacteriostatic System

Controls helmet padding bacteria and bacterial proliferation to minimise volatile organic compound (VOC) formation inside helmet liners, helping provide 8 hours of protection.

BOTANICAL BIOACTIVES

Neem Extract

Azadirachtin, Nimbin, and Nimbidin help interfere with bacterial cell membrane formation.

LINER OPTIMIZATION

pH + Humectants

Engineered around scalp pH and textile liner absorption for balanced freshness.

THE MECHANISM

BEYOND JUST A FRESH SCENT

A science-backed helmet hygiene technology designed not just to mask odour - but to help control the bacterial growth responsible for it.
01

DISRUPTS BACTERIAL CELL FUNCTION

Hygena’s antimicrobial actives interact with bacterial cell membranes, disturbing membrane integrity and essential cellular processes. This can interfere with ion balance, respiration and energy production - making it harder for bacteria to remain metabolically active and multiply.
02

SLOWS BACTERIAL REPLICATION

Bacteriostasis works by keeping bacterial growth under control rather than simply masking the odour. By interfering with processes required for bacterial growth and division, Hygena helps prevent the bacterial population from rapidly increasing inside the helmet liner.
03

HELPS CONTROL ODOUR AT THE SOURCE

Knowing how to clean a helmet inside goes beyond removing visible dirt - controlling the bacteria responsible for odour is an important part of helmet hygiene. Hygena helps reduce the microbial activity that contributes to odour formation - instead of simply covering the smell with fragrance.
04

PLANT-BASED ANTIMICROBIAL SUPPORT

Neem and other botanical actives provide additional antimicrobial support. Neem extracts have demonstrated inhibitory activity against several bacterial species and may also interfere with biofilm-associated growth, although the precise molecular mechanisms vary by extract and bacterial species.
POWERED BY

FUNCTIONAL INGREDIENTS

Neem

Neem

Naturally known for its antibacterial and odor-control properties that help support helmet hygiene.

Tea Tree

Tea Tree

Helps fight odor-causing microbes and keeps helmet interiors feeling cleaner and fresher.

Aloe Vera

Aloe Vera

Supports scalp comfort with soothing properties designed for regular everyday use.

Chamomile

Chamomile

Known for its calming and gentle properties that help reduce irritation during daily wear.

Together, these functional ingredients help create a helmet hygiene formula that is effective, fresh, and scalp-friendly for everyday riders.

THE HELMET–SCALP CONNECTION

A helmet is designed to protect your head. Hygiene is what protects your scalp.

THE PROBLEM

Sweat +
Moisture

Every ride introduces sweat into the liner.

Dirt + Oil
Build-Up

Sweat mixes with oil, dead skin, dust & pollution.

Warm + Humid
Environment

Low airflow keeps the liner warm and humid.

Microbial
Growth

Bacteria & fungi can multiply, causing odour & scalp discomfort.

Repeated Exposure

Same contaminants come back in contact with your scalp.

HOW HYGENA SUPPORTS YOUR SCALP

01

Controls the Source

Bacteriostatic actives help control bacterial growth inside the liner.

02

Keeps It Fresh

Neutralises odour at the source instead of simply masking it.

03

Scalp Friendly

Helps reduce repeated exposure to sweat, dirt & microbes, supporting a cleaner scalp environment.

QUICK & PRACTICAL: Spray. Let it dry. Ride with a cleaner, fresher helmet every day.

HOW HYGENA CHANGES YOUR HELMET

Without Hygena

Sweat
Bacteria Multiply
Odour Builds
More Buildup
Traditional sprays only cover the smell while bacterial growth continues inside the helmet liner.

With Hygena

Bacteriostasis
Sweat
Growth Controlled
Great freshness
Fresher Liner
Hygena’s Bacteriostasis Technology helps interrupt bacterial replication before strong odour develops.

And most importantly - it works fast.

Just spray. Wait 10 seconds. Ride.

Because hygiene shouldn't slow you down.
