Oxygen bleach(colour-safe)
The stain removal performance of bleach. Without the bleach consequences.
Highlights
- Active oxygen stain removal — sodium percarbonate releases hydrogen peroxide in water — breaks down protein, food, and organic stains through oxidation without the colour-destructive chemistry of chlorine bleach.
- Colour-safe — non-chlorine formulation means no dye damage, no fabric degradation, and no colour stripping across mixed institutional linen loads containing coloured uniforms and patterned items.
- pH 10–11 alkaline activation — optimises hydrogen peroxide release — effective stain treatment even in cold-water wash cycles without hot water activation.
- 10–20 gm per load — precise, low-dose stain treatment for institutional laundry cost control.
- Pre-soak protocol — 30–60 minute warm-water pre-soak capability for heavily stained items — blood, food contamination, and organic residues characteristic of healthcare and industrial laundry.
Product overview
Chlorine bleach occupies an awkward position in institutional laundry management: it is chemically effective against the stains it targets, but its operational consequences — colour damage on mixed loads, progressive fibre degradation on repeated use, incompatibility with coloured uniforms, and the handling requirements of a strongly oxidising chemical — make it unsuitable as a routine stain treatment in most modern institutional laundry programmes.
Alle’s ClinX Labs Oxygen Bleach provides the stain removal performance required in healthcare, industrial, and educational laundry operations without these consequences. The active oxygen system — sodium percarbonate releasing hydrogen peroxide in water — breaks down the chromophore structures of organic stains through oxidation rather than the aggressive halogenation mechanism of chlorine. The distinction matters: oxidation targets the optical properties of the stain molecule without attacking the dye chemistry of fabric or the protein structure of the fibre itself.
The pH 10–11 alkaline activation ensures sufficient hydrogen peroxide release for effective stain treatment in the cold-water and low-temperature wash cycles increasingly specified in institutional laundry programmes for energy efficiency. The pre-soak protocol extends treatment capability to heavily contaminated items — blood-stained medical linen, oil-contaminated industrial garments, heavily food-soiled educational catering uniforms — that require extended contact time for complete stain remediation.
The chemistry
| How does oxygen bleaching work, and why is it safe for colours when chlorine bleach is not?
Sodium percarbonate (2Na₂CO₃·3H₂O₂) dissolves in water to release sodium carbonate and hydrogen peroxide. The hydrogen peroxide in alkaline solution decomposes to release hydroperoxyl anions (HOO⁻) — the active oxidising species responsible for stain breakdown. These species react with the chromophore groups (the molecular structures responsible for colour) of organic stain molecules — blood haem groups, food pigments, wine tannins — converting them to colourless oxidation products. The stain’s colour is destroyed without removing the stain molecule from the fabric. Chlorine bleach operates through a fundamentally different mechanism: sodium hypochlorite releases hypochlorous acid (HOCl), which chlorinates organic molecules rather than oxidising them. This halogenation reaction is far less selective than oxidation — it attacks the chromophore groups of textile dyes with comparable efficiency to those of stain molecules, causing colour fading and stripping. It also reacts with the protein components of natural fibres, progressively degrading the keratin in wool and the cellulose structure of cotton under repeated application. The colour-safety of oxygen bleach is therefore not a marketing claim but a consequence of the chemistry: the hydroperoxyl anion is a selective oxidant with insufficient reactivity to attack the sulphonate and azo dye structures used in modern textile dyeing, while being highly reactive with the simpler chromophore groups in food, blood, and organic stains. This selectivity makes oxygen bleach the appropriate stain treatment specification for mixed institutional linen loads containing coloured and patterned items. |
Application & usage
- Standard wash addition add 10–20 gm to the washing machine drum with linen before the main wash cycle. Alternatively, add to the detergent compartment.
- Pre-soak (heavily stained) dissolve 20 gm per 5 litres of warm water (40°C+). Soak stained items for 30–60 minutes before the standard wash cycle.
- Temperature most effective above 30°C. For cold-water washing, increase dose to 20 gm or use warm pre-soak to initiate hydrogen peroxide release before the cold wash.
- Combination use can be used alongside Alle’s ClinX Labs Laundry Liquid Detergent in the same wash cycle for combined cleaning and stain treatment.
- Exclusions do not use on silk, wool, or cashmere — use Alle’s ClinX Labs Woollen Wash for these fabric types.
Usage economy
| 15 gm average dose. One 5-litre pack. 330+ stain treatment cycles.
At 15 gm average dose per load, a single 5L (5,000 gm) pack delivers approximately 333 complete wash treatments. For a hospital laundry running 50 stain-treatment loads per week, one pack covers approximately 6–7 weeks of stain management protocol. The elimination of chlorine bleach from the laundry programme reduces chemical handling risk, removes colour damage liability from mixed linen loads, and simplifies the COSHH documentation for laundry chemical management. |

Caution & storage
| For professional and institutional use.
Oxidising agent. Keep away from combustible materials, reducing agents, and acids — contact with incompatible materials can cause fire or release of oxygen. Avoid inhalation of powder dust during dispensing — use in ventilated areas. In case of eye contact, rinse immediately with water for 15 minutes. Do not ingest. Keep out of reach of children. Store in original sealed container in a cool, dry location below 30°C, away from moisture, heat sources, and incompatible chemicals. Exposure to moisture in storage causes premature oxygen release and product degradation — keep container tightly sealed. Do not store in metal containers. Shelf life 18 months from manufacture date, in sealed storage. |
