Structure Property Relationships of LABSA:
Under ideal conditions the cleaning power of BAS and LABSA is very similar, however LABSA performs slightly better in normal use conditions, due to LABSA being less affected by hard water.
Within LABSA itself the detergency of the various isomers are fairly similar, however their physical properties (Krafft point, foaming etc.) are noticeably different.

In particular the Krafft point of the high 2-phenyl product (i.e. the least branched isomer) remains below 0 °C up to 25% LABSA whereas the low 2-phenyl cloud point is ∼15 °C.
This behavior is often exploited by producers to create either clear or cloudy products.

Environmental fate of LABSA:
Biodegradability has been well studied, and is affected by isomerization, in this case, branching.
The salt of the linear material has an LD50 of 2.3 mg/liter for fish, about four times more toxic than the branched compound; however the linear compound biodegrades far more quickly, making LABSA the safer choice over time.

LABSA is biodegraded rapidly under aerobic conditions with a half-life of approximately 1–3 weeks; oxidative degradation initiates at the alkyl chain.
Under anaerobic conditions LABSA degrades very slowly or not at all, causing LABSA to exist in high concentrations in sewage sludge, but this is not thought to be a cause for concern as LABSA will rapidly degrade once returned to an oxygenated environment.

Environmental and Safety Considerations of LABSA:
Most anionic surfactants including LABSA are nontoxic in nature.
However, prolonged exposure to these surfactants, could irritate and damage the skin through the disruption of the lipid membrane, which protects the skin and other cells.
On the other hand, the biodegradability is determined by surfactant's hydrophobic hydrocarbon group.
