Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009 Directives for
Standardization – Part 1. Structure and Drafting of Standards.
This Standard replaced QB/T 1224-2007 Liquid Detergent for Fabric.
Compared with QB/T 1224-2007, this Standard has the major technical changes as
follows.
--- Revise the basis for the raw material requirements;
--- Revise the total content index requirements for the active substances in the
ordinary laundry detergent;
--- Revise the pH determination concentration of the laundry detergent;
--- Revise the solution concentration, reference compound, reference concentration
and detergency evaluation requirements when determining the detergency of
laundry detergent;
--- Revise the name of pre-washed stain agent of the fabric;
--- Revise the solution concentration, reference compound, reference concentration,
detergency evaluation requirements when determining the detergency of the pre-
washed stain agent of the fabric;
--- Revise the basis for the inspection rules, marking and package requirements;
--- Revise the quality guarantee period of the product;
--- Add the type of silk and wool detergent and the corresponding index requirements;
--- Add the evaluation requirements for the detergency of the silk and wool detergent;
--- Add the index requirements for the laundry detergent, silk and wool detergent,
collar and cuff pre-detergent against the phosphorus pentoxide;
--- Cancel the grade requirements for the laundry detergent, collar and cuff pre-
detergent.
This Standard was proposed by China Light Industry Council.
This Standard shall be under the jurisdiction of National Technical Committee for
Standardization of Surface Active Agent and Detergent (SAC/TC 272).

restoring to the room temperature; the other piece of specimen shall be stored in the
(-5±2) °C refrigerator for 24h; take out and observe after restoring to the room
temperature.
6.4 Total active substance
Generally, it shall be determined according to the Method-A specified in Clause 7 of
GB/T 13173-2008.
When the product formula contains the surface active agent components insoluble to
the ethanol, or when the test results of total active substance content specified in the
customer ordering contract exclude the water co-solvent, and asked to determine
through the chloroform extraction method, then it shall be determined by Method-B
specified in Clause 7 of GB/T 13173-2008.
6.5 pH
It shall be performed as per the provisions of GB/T 6368. At the test temperature of
25°C, use the boiling and cooling distilled water to prepare the specimen solution with
mass concentration of 1%, then mix evenly with the structured laundry detergent
specimen solution with mass concentration of 0.1%, then determine it.
6.6 Total Phosphorus pentoxide
Inspect as per the provisions of Clause 6 in GB/T 13173-2008.
6.7 Detergency
6.7.1 Standard laundry detergent
Prepare as per the relevant provisions of No.1 amendment of GB/T 13174-2008.
6.7.2 Determination of detergency
a) Laundry detergent, silk and wool detergent. perform as per the provisions of GB/T
13174.
b) Collar and cuff pre-detergent
Pretreatment of dirty-cloth test piece. take 3 blocks of round dirty-cloth test
pieces of JB-01, JB-02, JB-03 with diameter of Φ4cm; respectively fold into one
culture dish (take one type of dirty-cloth as one group). Weigh 2.0g of specimen
into the beaker; add 2mL of 250mg/kg hard water to dilute; use the pipette to
average drop the evenly-mixed specimen onto each dirty-cloth in sequence of
JB-01, JB-02, JB-03; use tweezers to flip gently; so that it can be totally wetted;
the dropping time shall be controlled within 1min; stand the soaked dirty-cloth
test piece for 5min. Take 250mL of the heated 30°C 250mg/kg hard water,
transfer the specimen remained in the pipette, beaker, culture dish and the
