Linear Alkyl Benzene, commonly known as LAB<\/strong>, is an important petrochemical intermediate used mainly in the production of surfactants such as Linear Alkylbenzene Sulphonate. It is widely associated with detergent, cleaning-product and industrial chemical manufacturing.<\/p>\n Because LAB is an important feedstock for downstream chemical processes, its purity and chemical characteristics must be carefully controlled. Parameters such as colour, moisture, specific gravity, Bromine Index, molecular weight, paraffin content, chain-length distribution, sulphonability and LAB content are important indicators of product quality.<\/p>\n In India, Linear Alkyl Benzene is covered by IS 12795:2020 \u2013 Linear Alkyl Benzene \u2013 Specification (First Revision)<\/strong>. The product is covered under the BIS Scheme-I<\/strong> certification framework. The current BIS Product Manual is PM\/12795\/1, August 2024<\/strong>, incorporating Amendment No. 1. It specifies 1 litre<\/strong> as the sample quantity and states that grouping is not applicable.<\/p>\n Qualitance India provides end-to-end BIS Certification consultancy for Linear Alkyl Benzene manufacturers, including regulatory assessment, documentation, laboratory coordination, testing support, Quality Assurance Plan preparation, factory inspection preparation and BIS licence assistance.<\/p>\n Linear Alkyl Benzene is a petrochemical material containing predominantly linear alkylbenzene molecules. It is an important raw material for the manufacture of sulphonated surfactants.<\/p>\n LAB is commonly used in the production of:<\/p>\n Consistent LAB quality is important because changes in composition can affect downstream sulphonation, processing behaviour and product performance.<\/p>\n The applicable Indian Standard is:<\/p>\n IS 12795:2020 \u2013 Linear Alkyl Benzene \u2013 Specification (First Revision)<\/strong>.<\/p>\n The current BIS Product Manual is:<\/p>\n PM\/12795\/1 \u2013 August 2024<\/strong><\/p>\n The Product Manual records:<\/p>\n BIS issued Amendment No. 1 to IS 12795:2020 in 2024.<\/p>\n BIS’s implementation guideline states that the amended and unamended standards were allowed to run concurrently until 8 October 2024<\/strong>, and that the amendment was to be implemented by that date.<\/p>\n The amendment included changes such as:<\/p>\n The BIS implementation guideline also states that there was no change in the prescribed product requirement<\/strong> as a result of the amendment; the changes were primarily related to methods and testing provisions.<\/p>\n Yes. Linear Alkyl Benzene is included in the BIS compulsory certification framework against IS 12795:2020<\/strong>. BIS’s current Scheme-I page continues to list Linear Alkyl Benzene along with the applicable Quality Control Order history and the 2026 temporary-suspension notifications.<\/p>\n The original regulatory framework requires covered LAB to conform to the applicable Indian Standard and bear the Standard Mark under a BIS licence according to Scheme-I.<\/p>\n The LAB QCO has undergone a temporary suspension in 2026.<\/p>\n BIS’s current compulsory-certification listing records:<\/p>\n At the same time, BIS’s current upcoming-QCO page lists:<\/p>\n Linear Alkyl Benzene \u2014 IS 12795:2020 \u2014 Enforcement date: 30 September 2026.<\/strong><\/p>\n Therefore, manufacturers should treat September 2026 as an important compliance-preparation period and verify the exact regulatory position immediately before commercial supply because the QCO position is subject to government notifications.<\/p>\n For a chemical product such as LAB, BIS certification requires more than submitting a laboratory sample. The manufacturer needs suitable analytical facilities, documented processes, trained personnel, calibration, batch traceability and regular testing.<\/p>\n Manufacturers should therefore prepare:<\/p>\n Early preparation can help avoid delays when the mandatory requirement becomes applicable.<\/p>\n The current Product Manual contains the practical certification requirements for IS 12795:2020.<\/p>\n It specifies:<\/p>\n Sample Quantity: 1 litre<\/strong><\/p>\n and:<\/p>\n Grouping Guidelines: Not applicable<\/strong>.<\/p>\n The Product Manual also states:<\/p>\n Raw Material: No specific requirement<\/strong>.<\/p>\n The licence scope is simply:<\/p>\n Linear Alkyl Benzene<\/strong>.<\/p>\n The current Product Manual specifies:<\/p>\n 1 litre<\/strong><\/p>\n as the sample quantity for laboratory testing during grant of licence, change in scope and applicable factory-surveillance activities.<\/p>\n Manufacturers should submit a representative sample that corresponds to the product being offered for certification.<\/p>\n The current Product Manual clearly states:<\/p>\n Grouping Guidelines: Not applicable.<\/strong><\/p>\n Unlike products where certification scope may be divided by size, grade or capacity, LAB certification is not structured through a conventional grouping table in this Product Manual.<\/p>\n The manufacturer’s focus should therefore be on consistent conformity of the product with all applicable requirements of IS 12795:2020.<\/p>\n The current Product Manual identifies the following principal requirements:<\/p>\n These tests collectively evaluate the physical, chemical and compositional quality of LAB.<\/p>\n The manufacturer must maintain adequate inspection and in-process controls to ensure that LAB meets the specified requirements and should maintain appropriate records.<\/p>\n Colour may be determined using the specified Saybolt or Lovibond methods.<\/p>\n Following Amendment No. 1, ASTM D 6045<\/strong> is also available as an alternate method for colour determination.<\/p>\n Specific gravity is determined at:<\/p>\n 15.5\u00b0C \/ 15.5\u00b0C<\/strong><\/p>\n The Product Manual references:<\/p>\n Moisture is controlled in ppm.<\/p>\n Available methods include:<\/p>\n The Doctor Test is carried out according to IS 1448 (Part 19)<\/strong>.<\/p>\n Flash point is determined using the closed-cup method.<\/p>\n The Product Manual references:<\/p>\n Bromine Index is determined by the applicable standard method.<\/p>\n The Product Manual references:<\/p>\n The relevant LAB is first sulphonated according to the applicable procedure and the resulting sulphonate is tested for ready biodegradability.<\/p>\n The Product Manual references:<\/p>\n The test is conducted once in two years or when specified changes occur, such as change in type, composition, raw-material source or process.<\/p>\n Distillation performance is assessed using the applicable method in:<\/p>\n IS 1448 (Part 18)<\/strong>.<\/p>\n The Product Manual identifies this as a routine test to be conducted once a week.<\/p>\n Molecular weight is determined using:<\/p>\n It is identified as a routine test for each control unit.<\/p>\n Paraffin content is determined using Annex C of IS 12795:2020.<\/p>\n The test is identified as a routine test for each control unit.<\/p>\n Sulphonability is determined using Annex D of IS 12795:2020.<\/p>\n The Product Manual specifies a routine testing frequency of once a week.<\/p>\n Chain-length distribution is determined using:<\/p>\n The 2024 amendment also specifies that standard linear alkylbenzene of C10 to C14<\/strong> shall be used for peak identification.<\/p>\n Refractive index is determined according to:<\/p>\n The Product Manual specifies a once-a-week routine frequency.<\/p>\n Tetralins are determined according to Annex H of IS 12795:2020.<\/p>\n The specified routine frequency is once a month.<\/p>\n LAB content is determined according to UOP 698-12<\/strong> and is identified as a routine test for each control unit.<\/p>\n The current Product Manual provides the following control framework:<\/p>\nWhat is Linear Alkyl Benzene?<\/h2>\n
