Sodium C12-14 alkyl sulfate

Sodium C12-14 alkyl sulfate (CAS 85586-07-8) is an anionic surfactant derived from a blend of C12 and C14 fatty alcohol chains; it offers a broader carbon range than single-cut sodium lauryl sulfate.

Where is Sodium C12-14 alkyl sulfate used?

• Personal care: primary surfactant in foaming, cleansing and emulsification systems
• Shampoos, body washes and liquid hand soaps: strong foam generation
• Household and industrial cleaners: grease cutting and soil dispersion on hard surfaces, particularly in high-dilution formulations
• Textile and leather processing: wetting and scouring agent that improves liquor penetration during fiber preparation and dyeing
• Paper manufacturing: incorporated into pulping and de-inking processes where foam behaviour and surface wetting are critical
• It provides effective sebum removal at a competitive cost.
• Very good washing, foaming, emulsifying and thickening properties in the presence of salt (NaCl).
• Adding cocamidopropyl betaine or other betaines can easily achieve the required final consistency of a cosmetic formulation.

Good to know: Not to be confused with single-cut sodium lauryl sulfate; the C12–C14 blend gives a broader carbon range.

Formulation notes

• The concentration in cosmetic products typically ranges from 0.01% to 50%.
• Sodium Laureth Sulfate causes less skin irritation than Sodium C12-14 alkyl sulfate.

Typical specification

• Available as an approximately 30% aqueous solution or as a powder/granulate with an active content of about 95%.
• Soluble in water, forming a clear solution.
• The lauryl alcohol used to make it can be derived from coconut oil (CNO) or palm kernel oil (PKO).

Storage, packaging and handling

• Tends to crystallize at low temperatures.
