Details
Most Indian toilet cleaners rely on 10.50% hydrochloric acid (HCl)—an aggressive mineral acid that produces choking acidic fumes, corrodes chrome bathroom fittings, and permanently micro-etches the ceramic glaze of the toilet bowl. Once etched, the porcelain becomes microscopically porous, trapping uric salts and manufacturing an artificial need for frequent, aggressive acid cleaning. Furthermore, mineral acids destroy the beneficial anaerobic bacterial cultures in septic and biodigester tanks. Shuunnya Spring Toilet Cleaner rejects mineral hydrochloric acid entirely. Engineered as a high-potency, thickened organic acid descaler, it pairs 6.00% L(+)-lactic acid with 3.00% citric acid at a measured bulk pH of 2.10. It dissolves 57.00 mg of calcium carbonate limescale per millilitre of cleaner (tested under IS 7983 Clause 4.4.2 methods). Being weak bio-based acids, it works safely in 10 minutes rather than 3, preserving the glassy smoothness of the porcelain glaze, protecting chrome fittings, and keeping septic tanks thriving.
- Dual Bio-Acid Descaling Engine (9.00% Total Organic Acid): Synergistic blend of 6.00% L(+)-lactic acid and 3.00% citric acid at measured pH 2.10 ± 0.20. Zero hydrochloric acid, zero sulphuric acid, zero sulphamic acid.
- Stoichiometric Descaling Capacity (57.00 mg/ml): Dissolves 57.00 mg of calcium carbonate scale per millilitre of product. Citric acid rapidly dissolves mineral bonds, while lactic acid drives the reaction into highly soluble calcium lactate (>70 g/L solubility), preventing white chalky crusts from re-precipitating under the rim.
- Pseudoplastic Xanthan Cling Gel (850–1,100 cP): Formulated with 0.80% bio-fermented xanthan gum. Under squeeze pressure through the angled nozzle, viscosity drops below 80 cP for effortless application; upon striking vertical porcelain, it instantly rebounds to ~900 cP, clinging under the rim for over 4.00 minutes to dissolve mineral scale before draining.
- Gentle Plant Surfactant Biofilm Lifter (1.50% ASM): 100% plant-derived Coco-Glucoside (non-ionic alkyl polyglucoside from coconut and corn sugars). Lifts urinary lipids, sebum, and organic biofilms with low, controlled foam that flushes away completely without persistent suds in the trap.
- How to Use & Dosage (50 ml): Direct the angled nozzle under the toilet bowl rim and squeeze ~50 ml evenly around the bowl. Allow the clinging gel to dwell for 10 minutes (or 30 minutes for heavy limescale rings). Brush lightly with a toilet brush, then flush. Use 2 to 3 times weekly for pristine sanitary porcelain.
- Double Organic Acid Preservation: Potassium Sorbate 0.20% and Sodium Benzoate 0.10% operate at >99% undissociated active biostatic state at pH 2.10, completely protecting the polysaccharide xanthan gum network against acidophilic moulds and yeasts over 24 months. Passes ISO 11930 Criterion A.
- Child & Pet Safety Deterrent (10 ppm Denatonium Benzoate): Dosed with the world's most bitter compound (<0.01% active) to render accidental swallowing by toddlers or pets immediately repulsive, backing up the child-resistant push-and-turn closure.
- Steam-Distilled Botanical Eucalyptus Aroma: Scented with 0.15% pure Eucalyptus Globulus Leaf Oil. Assayed Limonene < 0.02% (< 200 ppm). Exempt under Insecticides Act s.38(1)(b) because no pest or insect claims are made. Aroma dissipates cleanly within 15 minutes.
- Packaging & Refill Economics: Packaged in 50% PCR rHDPE angled duck-neck bottles (500 ml / 1 L) with directional jet nozzles and certified push-and-turn child-resistant caps. The 2 L recyclable mono-material polyolefin refill pouch refills the 500 ml bottle 4 times, reducing packaging plastic waste by 78.00% and bringing cost down to ₹12.48 per clean.
- 100% Glaze & Septic Safe: Preserves porcelain glaze gloss (passes IS 7983 Cl. 4.5); completely non-corrosive to chrome, SS304, and PVC pipes. Genuinely safe for septic and biodigester tanks at the recommended 50 ml application.
- The Mandatory Stone Warning: Calcium carbonate is what limescale is made of, and it is also what marble, Kota stone, limestone, and terrazzo are made of. A single splash permanently etches natural calcium stone in seconds. Keep strictly inside ceramic bowls.
- Never Mix With Bleach: Mixing any acid with sodium hypochlorite (bleach) liberates toxic chlorine gas. Never mix with bleach or other cleaning chemicals.

What is left out, and what took its place
- Hydrochloric acid (HCl)
- Replaced by 9.00% bio-fermented organic acids (Lactic 6.00% + Citric 3.00%). Zero choking acid fumes, zero respiratory distress, zero micro-pitting of porcelain glaze.
- Sulphuric and sulphamic acids
- Replaced by bio-derived food acids. 100% readily biodegradable with low aquatic toxicity.
- Chlorine bleach (Sodium Hypochlorite)
- Zero bleach. Bleach cannot dissolve mineral scale; mixing acid and bleach generates lethal chlorine gas. We eliminate bleach entirely.
- Quaternary ammonium compounds (Quats / BKC)
- Replaced by mechanical and chemical dirt removal with 1.50% plant glucosides. Zero quats, zero respiratory sensitization, zero aquatic bioaccumulation.
- Synthetic fragrances and perfumes
- Replaced by 0.15% steam-distilled eucalyptus essential oil. Zero synthetic musks, zero phthalates, zero masking agents. Clears in 15 minutes.
- Synthetic coal-tar and azo dyes
- Zero artificial dyes (no Acid Blue 9, etc.). Completely natural, transparent to very pale straw gel that leaves zero stains on vitreous china.
- Isothiazolinones (MIT, CMIT, BIT)
- Replaced by food-grade organic salts (Potassium Sorbate 0.20% + Sodium Benzoate 0.10%), fully active at pH 2.10 without skin sensitization.
- Virgin single-use plastic bottles
- Replaced by 50% PCR rHDPE bottles and multi-layer recyclable mono-material PE refill pouches that reduce plastic mass by 78.00% per dose.
- What we will not claim
- We will never claim 'instant 3-second miracle descaling' because safe organic fruit acids dissolve calcium carbonate stoichiometrically over 10 minutes without corroding metal or etching glaze. Nor do we make unproven biocidal 'kills 99.9% germs in seconds' claims; hygiene is achieved through genuine organic acid descaling, lipid biofilm lifting, and thorough sanitary flushing.
