What is your active‑matter content? Many products on the market have measured values far below labelled figures.
+
Labelled true active‑matter content: 70‑80%. Third‑party SGS/CNAS test reports via two‑phase titration or potentiometric titration are supplied with each shipment. Batch‑specific factory QC certificates are also available. You may send samples for third‑party testing or on‑site measurement. Full refund if test data does not match specifications.
Quote your price. What is the active‑matter content? How many kilograms/pounds can you produce?
+
Quotation based on target finished‑product active‑matter content. To make 15% finished product, approx. 18% mother‑batch material is used. We will provide a full‑range active‑matter grading ratio & cost table; select grades according to your requirements for full transparency.
The mixture separates three days after dilution with water: clear liquid on top, turbid sediment at the bottom.
+
Separation is mostly caused by water quality and formula stability, not defective mother‑batch material. The formula contains chelating agents to bind calcium‑magnesium ions and solubilizers to improve compatibility. Softened water or pure water is recommended for preparation; thickeners shall be fully dissolved beforehand. Follow SOP: 12‑month shelf‑life without delamination at ambient temperature. We can supply a reference tank sample for comparison.
I added salt for thickening, but the solution became thinner and whitish with more salt added.
+
Add salt in small multiple portions: stir thoroughly after each addition. Stop adding when no further thickening occurs after three consecutive additions. For already‑thinned and whitish batches: do NOT add more salt. Add 20% AES solution or salt‑free finished liquid under agitation until transparency recovers, then calculate and supplement for bulk production. Salt dosage is calibrated against temperature in the ratio sheet to avoid processing failures.
Same formula turns jelly‑like in winter but overly thin in summer.
+
This is normal temperature‑dependent behaviour, not a quality defect. Graded ratio sheets by temperature are provided (including high‑temperature version for Vietnam / Southeast Asia 35‑40 ℃). Select the corresponding grade for local climate. Minor solubilizer (ethanol / propylene glycol) may be added to mitigate low‑temperature turbidity.
Claimed 1:20 dilution ratio, but cleaning performance is poor; 1:10 dilution is required instead.
+
We state realistic dilution limits based on true active‑matter content without over‑advertising dilution multiples. To meet GB standard general‑grade detergency (active‑matter ≥15%): for 82% mother‑batch material, dilution ratio approx. 1 : 4.5. For concentrated household grade: 1 : 8‑10. GB/T 13174 standard stained‑cloth detergency test data is available upon request for quantifiable performance.
Can this really produce 50 jin of laundry detergent from one unit?
+
Frankly speaking: you cannot have both “qualified laundry detergent” and “50‑jin yield”. 1 kg of 70% mother‑batch material can only produce approx. 4.7 jin of finished product at national‑standard 15% active‑matter. For household‑usable concentration: approx. 8‑10 jin. We do not compete on exaggerated dilution yield; we focus on accurate dosing by target active‑matter and guaranteed finished‑product compliance.
Workers have daily contact. Will it cause hand irritation or allergy?
+
Finished‑product pH: 5.0‑7.5, near‑neutral to weakly acidic. Phosphorus‑free, no fluorescent whitening agents. Cocamidopropyl betaine and other mild amphoteric surfactants plus skin‑care additives can be incorporated to reduce irritation. Custom mild‑formula version available for baby‑safe / sensitive‑skin applications.
Export to Southeast Asia. What standards do you comply with? Is MSDS available?
+
MSDS/SDS, TDS, active‑matter and composition test reports are provided. Phosphorus‑free and fluorescent‑free formulation, compatible with EU REACH. HS code 3402 for export. China‑ASEAN ACFTA Form‑E available for zero‑tariff treatment. Vietnam terminal labelling complies with Decree 43/2017; Vietnamese‑language label suggestions provided. High‑temperature‑resistant formula version and local‑market formulation support are available.
Fragrance only lasts a few hours / smells chemically harsh.
+
Two fragrance tiers: fresh scent & long‑lasting scent. Low‑grade pungent fragrances are avoided. Microcapsule fragrance‑locking technology for long‑lasting performance, nominal 72‑hour fragrance retention. Cationic polyacrylamide stabilises microcapsule dispersion to prevent sedimentation and delamination. Popular fragrance options: lavender, perfume‑style, Hilton‑style, Jo Malone‑style.
Can Jo Malone‑style and Hilton‑style fragrances be customised?
+
Custom fragrances and fragrance‑retention grades are supported. Fragrance samples will be confirmed before bulk‑order production. OEM / ODM private‑labelling service available.
Calculations show mother‑batch material is not cost‑effective. Buying finished goods or self‑formulation seems cheaper.
+
Mother‑batch material is not merely low‑cost raw material; its value lies in operational convenience, formula stability, compliance assurance and freight savings. Cost‑calculation logic: (mother‑batch unit price ÷ dilution ratio) + auxiliary material cost (salt / fragrance / preservative / thickener) = finished‑product raw‑material cost, plus formulation and quality control. This offsets waste‑product risks and unstable quality from self‑trial‑and‑error. High‑concentration format delivers significant freight‑cost advantages, which is key for export business.
We are new‑comers with limited experience. Can you provide full‑process production guidance?
+
Turn‑key solution: mother‑batch liquid, complete ratio sheets, preparation SOP, video tutorials and free samples. Equipment‑selection consultation is optional. Two major pitfalls for beginners (salt‑induced thinning, undissolved thickener) are pre‑calibrated in ratio sheets with fixed salt dosage, feeding sequence and temperature parameters. Remote on‑line support for your first‑few batches to guarantee stable output.
Is viscosity consistent batch‑to‑batch? Previous supplier had large batch‑to‑batch viscosity variations.
+
Fixed active‑matter specifications, batch‑by‑batch QC certificates and standard‑SOP manufacturing ensure inter‑batch consistency. No repeated parameter adjustment is needed once your filling‑line parameters are set.
Barrel leakage caused heavy spillage on last delivery.
+
Heavy‑duty HDPE barrels, reinforced barrel‑seals, pallet wrapping & reinforcement. Marine‑grade outer packaging / IBC tote tanks with anti‑leak treatment for export shipments. Compensation or replacement for damaged goods upon arrival per agreement.
