Foreword
GCC Standardization Organization (GSO) is a regional organization which consists of the 
national standardization bodies of GCC member states. One of GSO main functions is to issue 
gulf standards and technical regulations through specialized technical committees.
GSO Technical Council in its meeting number (52) held on 10/10/1443H, which corresponds 
to 12/05/2022, has approved the update of the translation of Gulf Standard GSO 151:2022 
titled "Synthetic Detergents –Household Synthetic Detergents Powder" in English language 
which was studied through the technical program of GSO Technical Committee for Chemical 
and Textile Products (TC01) in SAUDI ARABIA schedule . (Arabic) text is considered the official 
text in case of any conflicts between the two. This document will cancel and replace the Gulf 
Standard GSO 151:2007. 
iiiGulf Standard GSO 151:2022  Synthetic Detergents –  
Household  Synthetic Detergent Powders  
  
1. SCOPE AND FIELD OF APPLICATION  
 This GSO standard is concerned with the requirements for household synthetic 
detergent  powders, which are mainly intended for washing clothes and fabrics.  
 2.          COMPLEMENTARY REFERENCES  
2.1        GSO 152 “Synthetic Detergents – Methods of Test for Household Synthetic  
Detergent  Powders”.  
2.2         GSO ISO 607 “Surface  active agents and detergents -  Methods of sample division”.  
2.3        GSO 2555 “ General Safety Requirements of Household Detergents  “. 
  3.          DEFINITIONS  
3.1        Synthetic detergent  
 A detergent in the form of powder for laundry for use by non- professionals, 
including in public launderettes to clean clothes and fabrics (could be of high or low foaming properties depending on the type of washing machine intended for its 
use including washing by hands). Powder detergents comprises essentially  of 
surface -active  matter and complementary components like performance enhancers, 
builders, optical brightening agents and fi llers or diluents, etc.  
3.2        Surface active matter (surfactant)  
 An organic chemical compound which when dissolved or dispersed in water is 
preferentially absorbed at an interface to lower the surface tension giving rise to properties of practical i nterest. It also contains  hydrophobic and hydrophilic 
portions.  
3.3        Surface tension   
 Tension of the surface film of a liquid tending a minimize its surface area.  
3.4         Builder  
 A complementary material added to organic or inorganic synthetic detergents such as zeolite or other and has limited ability of detergency during washing when used alone, but when added to a synthetic detergent its effectiveness is improved by reducing wat er hardness.  
3.5        Optical brightening agent   
 An organic chemical compound absorbed by textile fiber during the process of washing, having tendency to transfer invisible ultraviolet light to visible light so that the textile reflects the most portion of light to give brightening effect.  
3.6        Filler agent  
 An inert material such as sodium sulphate added to the synthetic detergent and does not increase its effectiveness.

© GSO 2022 — All rights reserved.   3.7        Anti-precipitant agent  
 Substances that  increase the stabili ty in liquid and prevents granules that cause dirt 
from aggregation. 
3.8        Performance enhancers  
 Substances added to synthetic detergents powders to enhance its overall 
performance. They can include substances which help reduce water hardness, substa nces which work removing specific stains like enzymes, anti -precipitant 
reverse, perfumes and optical brightening agents.  
3.9        Consignment  
 The quantity of synthetic detergent powders dispatched or received at one time and covered by particular contract or shipping documents.

enhancers such as enzymes and may also contain one or  more of conventional 
builders, such as, sodium carbonate, Zeolites, or sodium silicate or any other similar 
substances.  
4.4        It shall have no injurious effect to the consumer or  to the fabrics  to be washed with 
it or to the environment  if used as per the recommended instructions of use .  
4.5        Its properties shall not cha nge to a degree that a ffects i ts activity and detergency

.4.6 . It shall have 
no adverse effect on the final condition of textile and garments after  being washed, 
when used according to the method indica ted on its container or labeled  marking.
