Does CAS 9043-30-5 define one isotridecyl alcohol ethoxylate grade?

No. The CAS covers a family with different nominal EO levels and distributions. It does not determine HLB, cloud point, hydroxyl value, physical form, or performance. Specify those attributes and their test methods when comparing an offered grade.

Can a branched isotridecyl ethoxylate be exchanged with a linear alcohol ethoxylate?

Not by name alone. Branching and EO level affect wetting, foam, oil affinity, and phase behavior. Compare candidates at the actual dosage, temperature, water quality, and electrolyte level used in the intended formulation.

Isotridecyl Alcohol Ethoxylate CAS 9043-30-5

Isotridecyl Alcohol Ethoxylate (CAS 9043-30-5), also called Polyoxyethylene Isotridecyl Ether or Ethoxylated Isotridecanol, is a nonionic surfactant family made from branched C13 alcohol and ethylene oxide. It is used for wetting, detergency, emulsification and degreasing in cleaning, textile and leather-processing systems. Confirm nominal EO, hydroxyl value, cloud-point method, active matter and application performance against the current COA, TDS and SDS.

Application and grade selection

Isotridecyl Alcohol Ethoxylates are selected for wetting, detergency, emulsification and degreasing in industrial cleaning, textile, leather and process formulations. Performance changes substantially with EO level.

Cleaning trials should compare wetting, foam, detergency, rinsing, hard-water tolerance and temperature response.
Textile and leather trials should verify substrate wetting, compatibility, extraction or scouring performance and finished-material quality.
Regulated or personal-care use requires a specifically documented grade and cannot be inferred from a generic industrial listing.

For related isotridecyl alcohol ethoxylate grades, see E-1307 and E-1309.

Storage and handling

Store in the original closed container in a dry, ventilated place away from excessive heat and strong oxidizers. Temperature may change viscosity or physical form; use only the supplier’s recommended conditioning and mixing procedure.

Safety and supply documentation

Use exact-grade test data and the current SDS for handling, transport and disposal.

For quotation, identify the required nominal EO or reference grade, cloud-point method, application, performance criteria, quantity, destination, package and required COA, TDS and SDS.
