ODORSTRIKE Ingredients: The Key Actives, Explained
The three key actives in Formula v3.1 and what each one is doing — plus 8 supporting ingredients, and the three that are deliberately not in it.
What are the ingredients in ODORSTRIKE?
ODORSTRIKE Formula v3.1 is built on three key actives: HPβCD (hydroxypropyl-β-cyclodextrin) traps the odor molecule, Zinc PCA neutralises it, and triethyl citrate slows fresh sweat breaking down — plus 8 supporting ingredients. It is glycerine-free, dries clear, and is not for use on skin. Exact concentrations are proprietary.

Most fabric sprays print "fragrance" and leave it there. That is legal and it is useless if you are trying to work out whether the thing in your hand actually removes odor or just covers it. So here are the three that do the odor work, with a line on what each one is doing.
One thing stated up front: the three key actives are named here; the supporting ingredients and the exact concentrations are not. The ratios are the part that took the longest to get right and they are the one piece of this that stays proprietary.
The key actives in Formula v3.1
Three key actives, plus 8 supporting ingredients. The supporting ingredients exist to keep the actives stable, sprayable and safe to keep in a pocket.
- HPβCD · TrapA ring-shaped molecule that cages odor compounds.
- Zinc PCA · NeutraliseBinds the volatile acids behind sweat smell.
- Triethyl Citrate · PreventSlows the breakdown of fresh sweat into new odor.
- + 8 moreSupporting ingredients that keep it stable, sprayable and lightly scented.

| # | Ingredient | What it does |
|---|---|---|
| 01 | HPβCD | Trap. Ring-shaped molecule that cages odor compounds inside its cavity so they cannot reach your nose. |
| 02 | Zinc PCA | Neutralize. Binds the volatile acids behind sweat smell so they stop becoming airborne. |
| 03 | Triethyl Citrate | Prevent. Slows the breakdown of fresh sweat, so new odor forms more slowly. |
| +8 | 8 more | Supporting ingredients that keep the actives stable, sprayable and lightly scented. |
The four-layer logic is trap, neutralise, prevent, sustained freshness. HPβCD captures the odor molecule that already exists; Zinc PCA deactivates it; triethyl citrate slows the next batch forming; zinc gluconate supports lasting freshness between wears. Research on cotton functionalised with cyclodextrin confirms treated cloth absorbs pungent odor vapours by forming exactly these inclusion complexes.(Fibers and Polymers, 2025)
ODORSTRIKE — Fabric Odor Mist
50ml pocket spray. HPβCD traps the odor molecule, Zinc PCA neutralises it. Fabric only, never skin. Dries clear in 15–30 seconds.

Three ingredients that are common in this category are excluded on purpose. Each was tested and each caused a specific, reproducible problem.
Glycerine is a humectant — its job is to hold water. That is useful on skin and actively unhelpful on cloth. It leaves a faintly tacky patch that never fully dries, which then collects lint and dust. On a black shirt you can see it. Leaving glycerine out is a large part of why the formula dries clear.
Zinc ricinoleate is a legitimate odor active and it is used widely, but it is a castor-derived zinc soap and it behaves like a soap. In a fine-mist pocket spray it clogged the nozzle and left a visible white residue on dark fabric. Zinc PCA does the neutralising job without either problem.
Sodium bicarbonate is the ingredient everyone suggests, because baking soda deodorises a fridge. In a formula that already contains zinc salts it precipitates zinc carbonate — the two react, the liquid goes cloudy, and both ingredients stop doing their job. It is chemically incompatible with the rest of the formula, not merely unnecessary.
No glycerine. No zinc ricinoleate. No sodium bicarbonate. No dyes. No oils. If you see any of those on a competing fabric spray, that is the thing to weigh against the residue you will see on dark clothing.
pH, fabric safety and the skin boundary
It is a water-based formula and a fabric product, not a skin product. Both of those matter for different reasons.
It is made for everyday washable fabrics (cotton, polyester, denim, blends and wool) and dries clear on them with no stiff residue when sprayed from 15–20 cm. Patch-test silk first.
It is still not for skin. ODORSTRIKE is not a body deodorant, not an antiperspirant and not a body spray. Spray the garment, let it dry, wear it. If you want the distinction between the two categories spelled out, deodorant vs fabric mist covers it, and the staining guide covers the fabrics that want a spot test first — silk, wool, zari and heavy embroidery.
What "up to 8 hours" means and what it does not
One application gives up to 8 hours of odor protection on fabric under normal office/commute conditions. The "up to" is not decoration.
Activity, heat and humidity all shorten the window. A desk day in air conditioning sits at the top of that range. A humid commute followed by a training session does not, and you would reapply. The claim describes a protection window on cloth under ordinary use, not a fixed guarantee and not a promise about your skin.
Two things it explicitly is not. It is not a wash replacement — a visibly dirty or heavily soaked garment needs laundering, and a synthetic with months of built-up residue needs a stripping wash. And it is not a health claim: zinc actives bind and neutralize volatile odor compounds on fabric, which is a statement about how the formula works on cloth, not a claim of any medical or skin benefit to you.

Frequently Asked Questions
What are the key ingredients in ODORSTRIKE?
ODORSTRIKE Formula v3.1 is built on three key actives — HPβCD (hydroxypropyl-beta-cyclodextrin), Zinc PCA and triethyl citrate — plus 8 supporting ingredients that make a stable spray. Exact concentrations are proprietary.
Is ODORSTRIKE safe to use on skin?
No. ODORSTRIKE is formulated for fabric and is not a skin product. It is not a body deodorant, an antiperspirant or a body spray, and it should not be applied to skin. Spray it on the garment, let it dry 15–30 seconds, then wear. If it contacts skin accidentally, rinse with water.
Does ODORSTRIKE contain glycerine?
No, and that is deliberate. Glycerine is a humectant, which means it holds water. On fabric that leaves a slightly tacky patch that never fully dries and then attracts lint and dust, particularly visible on dark clothing. Leaving it out is what allows the formula to dry clear with no stiff residue.
Is ODORSTRIKE safe on coloured clothes?
It is made for everyday washable fabrics (cotton, polyester, denim, blends and wool) and dries clear on them with no stiff residue when sprayed from 15–20 cm. Patch-test silk on a hidden seam first, and do not use it on dry-clean-only garments.
What does 'up to 8 hours' actually mean?
It means one application gives up to 8 hours of odor protection on fabric under normal office/commute conditions, and 'up to' is doing real work in that sentence. Activity level, ambient heat and humidity all shorten it. A desk day in air conditioning sits at the top of that range; a humid commute followed by a gym session does not. It is a protection window on cloth, not a guarantee, and it is not a claim about your skin.
