General Purpose, Glass & Floor Care

The economical tier relies on linear alkylbenzene sulfonate (LAS) as the sole surfactant, supplemented by sodium carbonate (soda ash) as an alkaline builder and sodium sulfate as a filler. LAS accounts for approximately 78–97% of detergent surfactant consumption globally, offering low raw-material cost (approximately $1.20/kg active matter) and high detergency against particulate soils.

Formulation FC-10.1-E — Economical Multi-Purpose Cleaner (Powder)

Procedure: Blend sodium carbonate and sodium sulfate in a ribbon mixer for 5 minutes. Spray-apply fragrance; add sodium LAS powder and dye; mix 10 minutes. Package in moisture-barrier containers.

Specification: pH 9.5 ± 0.3 (1% solution, 25°C); active matter 8.0% ± 0.2%. Use dilution: 20–40 g/L warm water for general cleaning; 80 g/L for heavy soiling.

In water hardness exceeding 250 ppm as CaCO, LAS forms insoluble calcium salts that reduce active matter availability and leave residue on dark surfaces. The high soda-ash content provides effective alkalinity for saponification of fatty soils but precludes use on unsealed aluminum, where pH > 9 can induce etching within 5 minutes of contact.

The medium tier introduces a nonionic alcohol ethoxylate (AE) co-surfactant and preservative system. The LAS-to-nonionic ratio of approximately 2:1 follows industry practice for synergistic blends.

Formulation FC-10.1-M — Medium Multi-Purpose Cleaner (Liquid)

Procedure: Dissolve sodium carbonate in water. Add sodium LAS and AE-7; mix 15 minutes. Add SXS, then preservative, fragrance, and dye sequentially. QS with water.

Specification: pH 8.5 ± 0.3; viscosity 150–400 mPa·s (Brookfield RVT, 25°C); active matter 9.2% ± 0.3%. The addition of AE-7 extends cleaning to greasy kitchen soils, while SXS maintains a single-phase liquid across 5–40°C storage. The preservative addresses microbial contamination of dilute surfactant solutions, particularly Pseudomonas species that metabolize LAS and produce off-odors within 4–6 weeks at 30°C.

The premium tier replaces a portion of LAS with alkyl polyglucoside (APG), adds sodium citrate and tetrasodium glutamate diacetate (GLDA) as green chelators, and incorporates encapsulated fragrance. GLDA demonstrates > 80% biodegradability (OECD 301E) and chelates calcium and magnesium across pH 4–12.

Formulation FC-10.1-P — Premium Multi-Purpose Cleaner (Liquid)

Procedure: Dissolve sodium citrate in water. Add APG, AE-7, and sodium LAS sequentially. Add GLDA, preservative, perfume capsules, and dye. Filter through 100 μm before filling.

Specification: pH 7.5 ± 0.3; active matter 11.5% ± 0.4%. The pH-neutral character permits use on food-contact surfaces without rinse requirements. The APG component contributes low irritation while GLDA prevents hard-water filming on glass and stainless steel.

Floor cleaners must reconcile detergency with low foam (for machine application), no-rinse compatibility (to save labor), and gloss retention. The formulation below achieves this through a nonionic-dominant surfactant system with an acrylic shine polymer.

Formulation FC-10.2-M — Floor Cleaner (Liquid, No-Rinse)

Procedure: Dissolve sodium carbonate and EDTA in water. Add AE-7 and SAS-60; stir 15 minutes. Add DPnB, then acrylic polymer dispersion under moderate stirring. Add preservative, fragrance, and dye.

Specification: pH 8.5 ± 0.3; foam height < 50 mm (Ross-Miles, 1%, 49°C); gloss retention ≥ 95% (ASTM D523, 60° geometry, vinyl tile, 10 cycles). The acrylic polymer deposits a sub-micron film restoring specular reflectance without slipperiness. No-rinse compatibility is validated by conductivity testing: 1:128 dilution leaves residue conductivity below 5 μS/cm.

Natural stone is vulnerable to acid etching at pH < 6, while strongly alkaline cleaners can saponify protective sealants. A neutral pH formulation (7.0–8.0) is essential .

Formulation FC-10.3-M — Marble/Ceramic Cleaner (Liquid)

Procedure: Dissolve sodium citrate and sodium bicarbonate in water. Add APG and AE-7 sequentially. Add preservative and fragrance. Filter through 50 μm.

Specification: pH 7.5 ± 0.2; active matter 3.0% ± 0.1%. Surface etch test: no weight loss on polished Carrara marble after 24-hour immersion (ASTM C97). Compatible with fluoropolymer, silicone, and acrylic stone sealers.

Glass cleaning presents a distinct physical chemistry challenge: any non-volatile residue after evaporation becomes a visible streak. Silicate glass has surface energy exceeding 70 mN/m when clean, but contamination reduces this to 30 mN/m or less, causing water to bead. An effective glass cleaner must lower surface tension to 25–30 mN/m for spontaneous wetting, then evaporate completely.

The classic formulation combines isopropanol (IPA) as volatile solvent, ammonium hydroxide as alkaline builder, and trace surfactant for wetting. IPA forms a minimum-boiling azeotrope with water (87.9% IPA / 12.1% water, bp 80.3°C) that accelerates evaporation.

Formulation FC-10.4-M — Glass Cleaner (Liquid)

Procedure: Add IPA to deionized water with stirring (flammable; ensure ventilation). Add APG and sodium gluconate. Add ammonium hydroxide last. Filter through 10 μm.

Specification: pH 10.5 ± 0.3; surface tension 28 ± 2 mN/m; evaporation time < 30 seconds (500 μL on 10 × 10 cm glass, 23°C, 50% RH). The surfactant level of 0.05% active is deliberately minimal—sufficient for wetting, yet low enough that crystalline residue stays below the visible threshold of ~50 ng/mm² on glass.

Mirror silver backing is vulnerable to alkaline attack at pH > 10, causing black-edge corrosion. This formulation operates at milder pH and incorporates an anti-fog agent.

Formulation FC-10.5-M — Mirror Cleaner (Liquid, Anti-Fog)

Specification: pH 9.0 ± 0.2; surface tension 27 ± 2 mN/m; anti-fog rating ≥ 8 hours (40°C, 90% RH). The sulfosuccinate adsorbs at the glass-air interface to suppress water-droplet nucleation, while propylene glycol remains as a sub-visible humectant film.

Furniture polish is an oil-in-water emulsion containing silicone oil for durability, lemon oil for cleaning and fragrance, and mild surfactant for soil removal.

Formulation FC-10.6-M — Furniture Cleaner/Polish (Emulsion)

Procedure: Heat oil phase (silicone, lemon, mineral oils) to 65°C. Heat water phase to 70°C; dissolve polysorbate 80, triethanolamine, and APG. Slowly add oil phase to water phase under high-shear mixing (3000 rpm). Maintain shear 10 minutes. Cool to 35°C; add preservative and dye.

Specification: pH 8.0 ± 0.3; emulsion stability > 6 months (centrifuge, 3000 rpm, 30 min); viscosity 800–1500 mPa·s. The silicone oil produces a dry-to-touch protective film with water-contact angle ~110°, dramatically reducing dust adhesion .

Electronic device cleaning requires a formulation that is non-conductive when dry and completely residue-free. A 70% isopropanol solution is the industry standard.

Formulation FC-10.7-P — Electronics-Safe Cleaner (Liquid)

Specification: pH 6.5 ± 0.5; surface resistivity > 1 × 10 Ω/sq (dry film, ASTM D257); residue after evaporation < 0.01 mg/cm². The 70:30 IPA:water ratio ensures rapid evaporation. The antistatic agent deposits a monolayer increasing surface conductivity to 10–10 Ω/sq, dissipating static charges without compromising ESD safety. The 0.2 μm filtration step removes particulates that could scratch displays or foul connectors.

Soft surfaces require chemistry that ensures fiber safety, residue minimization, and foam control.

Carpet extraction cleaning involves spraying detergent, agitating, and vacuum-extracting. The cleaner must generate controlled foam and dry without sticky residue.

Formulation FC-10.8-M — Carpet Extraction Cleaner (Liquid)

Specification: pH 9.5 ± 0.3; foam height 120–180 mm (Ross-Miles, 0.25%, 49°C); dilution 1:80 to 1:160 for truck-mount extractors. The LAS:AE:CDEA system produces foam of moderate stability for soil suspension during 5–10 minute dwell time. Wool and silk carpets require neutral-pH formulations (6.5–7.5) to prevent fiber degradation.

Upholstery fabrics include natural fibers with tighter weaves. This formulation uses lower surfactant concentration, milder solvents, and incorporates fabric softener and odor neutralizer.

Formulation FC-10.9-M — Upholstery Cleaner (Liquid)

Specification: pH 7.5 ± 0.3; active matter 5.5% ± 0.2%; colorfastness rating 4–5 (AATCC 116, 10 fabrics). The APG:SAS blend shows no tendency to solubilize acid dyes in wool and nylon at pH 7.5. Zinc ricinoleate complexes volatile odorants (amines, thiols) through coordination chemistry rather than masking with fragrance.

Table 10.1 — General Purpose Cleaner Comparison Matrix

The matrix reveals three selection principles. First, the inverse relationship between active matter and evaporation rate: glass and electronics cleaners contain minimal surfactant to ensure residue-free drying, while carpet and floor cleaners require higher active levels for soil suspension without mechanical wiping. Second, pH correlates with soil-removal aggressiveness and surface risk—formulations at pH > 9 deliver superior grease cutting but are restricted to alkali-tolerant surfaces. Neutral-pH formulations sacrifice heavy-duty performance for broad compatibility including food-contact stone and natural fibers. Third, cost efficiency demands matching tier to application: deploying FC-10.1-P on industrial floors represents a 2.6× cost premium with minimal gain over FC-10.1-E, while using FC-10.1-E on sealed marble risks etching that exceeds any cleaning-cost savings.

Multi-Purpose Cleaner Tier Comparison

Figure 10.1 — Multi-purpose cleaner tier comparison across active matter, surfactant cost, biodegradability, grease cutting, and mildness. Grease cutting and mildness scores derived from standardized soiled panel testing (ASTM D4488, soil D, n=5). Data compiled from supplier literature and internal benchmarking .

The chart demonstrates that the premium tier commands a surfactant cost roughly 2.8× the economical tier but delivers 27% higher biodegradability and a 3-fold mildness improvement. The grease-cutting advantage is incremental (8.0 vs. 5.0), indicating diminishing returns for heavy-duty applications where the economical formulation at higher use concentration may suffice.

Table 10.2 — Stain Removal Efficacy by Surface and Cleaner Type

Scoring: Standardized soiled panel test (ASTM D4488, modified), 1-minute contact, mechanical wiping, reflectance. Score 10 = complete removal; 0 = no change. n = 5.

FC-10.4-M excels at fingerprint removal (9.5) through IPA action on skin sebum but performs poorly on tannin stains (5.0) because volatile solvents lack dwell time to break down coffee pigments. FC-10.8-M achieves the highest motor-oil score (9.0) through the synergistic LAS:AE:CDEA system with DPnB solvent at extended dwell times. FC-10.9-M shows highest pet-stain score (8.5), attributable to zinc ricinoleate and the mild APG:SAS blend that does not set protein stains through alkaline denaturation. FC-10.1-E provides adequate performance across soils (5.5–8.5) but never achieves top marks—a predictable trade-off of broad-spectrum design.

Table 10.3 — Ingredient Summary and Safety Classifications

This summary underscores the safety considerations differentiating application categories. Volatile solvent formulations carry flammability classifications restricting shipping and storage but are necessary for residue-free drying. Alkaline formulations require corrosive labeling but deliver pH-driven saponification on fatty soils. Neutral-pH formulations minimize hazard classification and expand the user base to sensitive environments, at the cost of reduced performance on heavy grease. Formulators must weigh these trade-offs against intended market, distribution channel, and regulatory jurisdiction when selecting from this portfolio. -e
