It is used as a detergent, in cleaning products, and in pesticides. The toxic effects of linear alkylbenzene sulfonate (LAS), quaternary alkylammonium chlorides (cationic surfactants[CS]), and their complexes (LAS‐CS) were examined in Dunaliella sp.
It is used because of its ability to help water to mix with oil and dirt so that they can be rinsed away (CosmeticsInfo.org). For LAS 48‐h median lethal concentration (LC50) values were 2.1 and 8.8 mg/L, respectively. It is difficult to volatilize, but it easy to dissolve in water and become a subtransparent solution. Sodium Dodecylbenzene Sulfonate is a white to light yellow sand-like solid. Linear Alkylbenzene Sulfonate (LAS) Industry Background. No.
Aquatic plants play an important role in maintaining the health of water environment in nature. The most common linear alkylbenzene sulfonate compounds used in pesticide formulations are (1) benzenesulfonic acid, dodecyl (CAS Reg. For alkali, dilute acid, it has stable hard water properties.
SDBS, short for sodium dodecyl benzene sulfonate, white or light yellow powder or flake solid. The glycerol content decreased quantitatively with increased concentrations of LAS, … 25155-30-0), both of which are currently approved for use as active and inert ingredients in registered pesticide products. Studies have shown that linear alkylbenzene sulfonate (LAS), a type of omnipresent pollutant, can cause toxic damage to aquatic plants.
Microbial community-level toxicity testing of linear alkylbenzene sulfonates in aquatic microcosms REASON FOR CITATION * Sodium Dodecylbenzene Sulfonate is on the Hazardous Substance List because it is cited by DOT and EPA.
LAS is the most preferred surfactant among detergent and personal care product manufacturers due to its comparatively low price and less toxicity. 27176-87-0) and (2) benzenesulfonic acid, dodecyl-, sodium salt (CAS Reg. It is … Linear alkylbenzene sulfonate (LAS) is anionic surfactant broadly used in detergents and cleaners. SDBS is micro toxicity. by proton nuclear magnetic resonance spectroscopic analysis of glycerol and in Chlorella pyrenoidosa by growth inhibition.
biodegradation of linear alkylbenzene sulfonates applicable to these current stepan products: bio-soft® d-40 bio-soft® s-101 bio-soft® s-118 nacconol® 90g stepwet® df-90 bio-soft® l2p-123 bio-soft® n-300 bio-soft® s-101 ls bio-soft® s-120 polystep® a-15 stepantan® dt-60 polystep®a-15f bio-soft® n-411 bio-soft® s-111 h nacconol® 40g
The acute toxicities of linear alkylbenzene sulfonate (LAS) and tributyltin (TBT) to the marine copepod Acartia tonsa were tested in 48‐h tests at two salinities, 18 and 28‰. The alkylbenzene sulfonates considered under the ABS RED risk assessment represent the alkylbenzene sulfonates used as active ingredients but which also comprise the predominant segment of the alkylbenzene sulfonate inert ingredient tolerance exemption expression given in Table 1. It is considered a linear alkylbenzene sulfonate (LAS), or specific classification of surfactant that is known to be especially soluble and effective at low concentrations. No.
