Two technical lines, solving two different problems

The portable spray aims to solve the problem of "where to put the sterilizing ingredients if not alcohol," while Aura Mist aims to solve "why transport water when 90% of a fragrance bottle is water." The formulation and structure of the two are completely different, and they were developed independently.

Without a membrane, nothing can be contained.

沒有留下影像,等於什麼都沒有留下。

Alcohol evaporates, taking with it everything it brought. Membranes do not.

Alcohol evaporates, and takes everything with it. A film doesn't.

Esguard Bonding Film Technology — cross-section Schematic cross-section of one film with two carriers: a cationic film-former bonds to a negatively charged skin or fabric surface, the polymer holds the sanitiser at the surface, and molecule-sized cavities hold the aroma and let it out slowly. 01 · BOND 附著 · 主動吸附 Cationic polymer anchors to the surface 02 · SANITISE 除菌 · 固定作用 Polymer holds the sanitiser at the surface 03 · RELEASE 緩釋 · 逐步釋出 Aroma held in a molecular cavity, let out slowly Alcohol-free mist · 無酒精噴霧 SKIN / FABRIC · 皮膚與織物 Bacteria meet the film, not bare skin Aroma, over hours · 香氣逐步釋出 微膜聚合物 Micro-film polymer 除菌成分 Sanitiser 香氣空腔 Aroma cavity 天然精油 Aroma 表面電荷 Surface charge

Bond

The micropolymer is positively charged, actively adhering to surfaces like skin and fabric. As it dries, it spreads out to form a continuous, non-sticky, ultra-thin film. Without it, only scattered dry spots would remain on the surface.

02 · SANITIZE
Disinfection and fixation
消毒

The antibacterial ingredients are added at the end of the manufacturing process and are fixed within this film, preventing them from dissipating with evaporation. Therefore, it is non-irritating to the nose, non-drying to hands, and leaves no white residue.

03 · RELEASE
sustained release · gradual release
發行

The natural essential oils are first combined with a fragrance carrier during the manufacturing process, enclosed in molecular-sized cavities, and remain on the surface with the film. They are then gradually released by body temperature and friction.

What's inside, and why?

內容有什麼?為什麼?
Micromembrane polymer
Micro-film polymer

The positively charged micellar polymer actively adheres to the surface of skin and fabric. It is responsible for keeping everything on the surface.

A positively charged microfilm polymer that binds to skin and fabric. It's what makes everything stay put.

Sterilizing ingredient
Sanitizing agent

is entrapped in the membrane rather than evaporated.

Held within the film rather than evaporating.

Fragrance carrier
Aroma carrier

cavities the size of molecules. During production, it is first combined with essential oils, allowing the fragrance to remain on the surface with the film.

Molecule-sized cavities, pre-loaded with the oil blend so the aroma stays with the film.

Natural essential oil
精油

The 36 parts are proportioned, and the fragrance is first combined with the carrier during the process.

Blended in 36 parts, pre-loaded into the carrier.

Moisturizing Soft Film Ingredients
保濕劑

To retain moisture and keep the ultra-thin film soft and intact.

Holds moisture and allows the very thin film to remain soft and knitted together.

Honest limits

We only speak of what can be proven. Current experimental data comes from bacteria removal tests on E. coli and Staphylococcus aureus. We have not yet conducted durability tests, so we will not claim how long the protection lasts; due to insufficient viral data, we will not make any related claims. Third-party certification testing is currently underway.

We only claim what we can show. Current data covers E. coli and S. aureus. We have no durability data, so we make no claim about how long anything lasts, and no virus claim of any kind. Accredited third-party testing is underway.

Tech 02 · Aura Mist Silicone Capsule Technology

It ships dry, you add the water.

A fragrance bottle is over 90% water. Aura Mist encapsulates fragrance and antibacterial ingredients in silica capsules, completely water-free at the time of manufacture. Users fill the bottle with water, twist the base to activate, and the ingredients are released. What's shipped are the ingredients, not the weight of water. One capsule can be activated three times; once used up, only the capsule is replaced, and the bottle is retained.

01 · ENCAPSULATE
Seal-less Encapsulation

The fragrance and antibacterial ingredients are encapsulated in an inert silicone shell, containing no water and requiring no preservatives, ensuring the scent does not deteriorate during its shelf life.

02 · 啟用
Water injection initiated

Fill the frosted inner chamber with purified water, twist the base to open the internal valve, invert, then return to the upright position—ingredients released, ready to spray.

03 · REFILL
Only replace the capsules.

One capsule, three activations. The bottle and nozzle are for long-term use; only a small capsule needs to be refilled.

R&D & IP

Research and Intellectual Property

Originating from the Hong Kong University of Science and Technology, the team independently developed two distinct technologies: the water-based micro-film formula for the spray, and Aura Mist's silicone capsule and water-activated structure. These technologies have since received international invention awards in Geneva, Singapore, and Hong Kong.
