BIO-SOFT® S-118

1 of 56 products in this brand
BIO-SOFT® S-118 is a c11.8 linear alkylbenzene sulfonic acid, serving as an anionic surfactant with remarkable detergency and compatibility with other anionic, amphoteric, and nonionic surfactants. Its low 2-phenyl content contributes to higher viscosities in liquid formulations with lower salt and active levels. Its extensive use spans various hi&i cleaners, including acidic formulations. Moreover, it can find application in emulsifiable concentrates, concentrated emulsions, and suspoemulsions within the agricultural sector.

Technical Details & Test Data

Neutralization of BIO-SOFT S-118

Neutralization Information: Temperature and pH must be controlled during neutralization of BIO-SOFT S-118 to prevent darkening of the product and corrosion of stainless steel equipment. The reaction temperature should not be allowed to exceed 50°C and the pH should not go below 6.5. Approximate amounts of BIO-SOFT S-118 and various alkalies for neutralization to make 100 lbs. of active dodecylbenzene sulfonate are shown below. Actual requirements will vary with each shipment. It may be necessary to make final adjustments on the basis of pH, adding more acid to lower the pH or more alkali to raise the pH, until the product is approximately neutral.

Neutralization of BIO-SOFT S-118 (to obtain approximately 100 lbs. of active neutralized LAS):

Alkali

BIO-SOFT S-118

25.3 lbs. NaOH (50%) 97.0 lbs.
37.7 lbs. KOH (45%) 92.7 lbs.
34.5 lbs. Triethanolamine (85%) 71.0 lbs.
19.5 lbs. Ammonium Hydroxide (28% NH3) 98.5 lbs.

 

Safety & Health

Toxicity

BIO-SOFT S-118 is slightly toxic orally (LD₅₀ = 500 - 2000 mg/kg) and when tested undiluted is corrosive to skin and eyes.

Packaging & Availability

Standard Packaging

BIO-SOFT S-118 is available in drums and in bulk quantities.

Storage & Handling

Storage & Handling
  • BIO-SOFT S-118 is a strong acid and should be handled with extreme care. Avoid contact with eyes and skin. Wash thoroughly after handling material. It is recommended that BIO-SOFT S-118 be stored in closed containers and kept in a cool, dry place. If material is frozen it should be heated gently and stirred to ensure it is homogeneous before use.
  • Bulk Storage Information: BIO-SOFT S-118 should be stored in vessels of 316 stainless steel or fiberglass with a corrosion liner. Heating and agitation are recommended for outside storage. Material should be stored between 26-38 °C) 80-100 °F. An internal hairpin coil of 316 stainless steel with low pressure steam (under 50 psig) should be used if heating is required. Pumps, pipes and transfer lines should be 316 stainless steel.
Workplace Exposure

Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.
