What protection do I need when handling these products?
Natural origin does not remove the need for gloves, eye protection and ventilation. Undiluted geraniol is a skin and eye irritant. Most applicator exposure happens while measuring and mixing.
The short answer
Gloves, eye protection and ventilation when handling concentrate, plus whatever the label specifies. Undiluted geraniol is a skin and eye irritant, and natural origin does not change that.
Why natural origin is not a safety argument
Concentration governs irritancy far more than origin. A plant-derived monoterpene at 30% in a drum is a different material from the same active at label dilution in a tank, and it behaves like the irritant it is. Several of the plant actives in use are recognised skin sensitisers — geraniol is one of the twenty-six fragrance substances the EU requires to be declared on cosmetic labels precisely because it is a recognised contact allergen.
The reasoning that a material is safe because it comes from a plant is the same reasoning that makes people careless with concentrate.
What exposure looks like
Most applicator exposure happens during measuring and mixing, not during spraying: splashes to the hands and forearms, and to the eyes when decanting at height. Then inhalation of vapour in an enclosed space such as a glasshouse or a store, and dermal contact from contaminated gloves, clothing and equipment after the job.
Repeat low-level dermal contact is how sensitisation develops, and it is easy to miss because no single exposure feels significant.
What to do
Wear chemical-resistant gloves and eye protection to measure and mix. Mix in a ventilated space and never in a confined one. Decant at a height where a splash cannot reach your face. Wash before eating, drinking or smoking, and change contaminated clothing rather than finishing the day in it.
Follow the personal-protective-equipment statement on the applicable label; where it asks for more than this page, it governs.
When to get advice
Rinse eyes or skin immediately after contact with concentrate and seek medical advice, taking the label with you. See a doctor about any rash that develops after handling — sensitisation is worth catching early, because it does not improve with continued exposure.
Which compounds are rated, and how
Ratings come from the compound records, so the same vocabulary appears here and on each compound page.
| Compound | Rating | Why |
|---|---|---|
| Chlorine dioxide | caution | Concentrated chlorine dioxide gas is a respiratory irritant and hazardous at elevated airborne concentrations. Occupational exposure limits exist; enclosed-space application requires ventilation and monitoring. |
| Geraniol | caution | Undiluted geraniol is a skin and eye irritant. Natural origin does not remove the need for gloves, eye protection and ventilation when handling concentrate. |
| NAD+ (nicotinamide adenine dinucleotide) | ok | Well tolerated topically; no photosensitising behaviour requiring night-only use. |
