Immediately flood affected skin with water while removing and isolating all contaminated clothing.
Gently wash all affected skin areas thoroughly with soap and water.
If symptoms such as redness or irritation develop, Immediately call a physician and be prepared to transport the victim to a hospital for treatment.
-INHALATION:
Immediately leave the contaminated area; take deep breaths of fresh air.
If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.
Provide proper respiratory protection to rescuers entering an unknown atmosphere.
Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

GENERAL DEFINITION:
Nansa HS 85/S is a dried sodium C10-13 alkylbenzene sulfonate.
Nansa HS 85/S is a high active anionic sufactant particularly suited to provide wetting, detergency and emulsifcation in a wide range of applications.
Nansa HS 85/S is a white to light yellow flakes, granules or powder.
Nansa HS 85/S is soluble in water. The primary hazard is the threat to the environment.
Immediate steps should be taken to limit its spread to the environment.
Nansa HS 85/S is used as a synthetic detergent.
The unique properties of surfactants and other chemistries, such as hydrotropes and dispersants, can be used to give numerous benefits within detergents, apart from the most obvious functions of cleaning and wetting.
Nansa HS 85/S appears as pale yellow thick liquid or solid with a faint detergent odor.
Mixes with water.
Soap bubbles may be produced.
Nansa HS 85/S is a cNansa HS 85/S of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group.
Along with sodium laureth sulfate, they are one of the oldest and most widely used synthetic detergents and may be found in numerous personal-care products (soaps, shampoos, toothpaste etc.) and household-care products (laundry detergent, dishwashing liquid, spray cleaner etc.).
They were first introduced in the 1930s in the form of branched alkylbenzene sulfonates (BAS).
However following environmental concerns these were replaced with linear alkylbenzene sulfonates (Nansa HS 85/S) during the 1960s.
Since then production has increased significantly from about one million tons in 1980, to around 3.5 million tons in 2016, making them most produced anionic surfactant after soaps.
FUNCTION:
-Modification of viscosity or rheology to enhance the flow characteristics of liquids.
-Optimisation of the volume, characteristics and stability of foam.
-Enhancing mildness to the skin and eyes.
-Suspension or emulsification of insoluble abrasives and builders.
-Separation of two distinct layers. Selection of a surfactant can therefore have a valuable impact on a formulation.
STORAGE:
Store in an area without drain or sewer access.
Separated from acids.
CHEMICAL PROPERTIES:
-Boiling point: 637°C
-Melting point: 277°C
-Relative density (water = 1): 1.06
-Solubility in water, g/100ml at 20°C: 25
-Vapour pressure: negligible
-Octanol/water partition coefficient as log Pow: 3.32
USES:
-Used as surfactant in industrial and household detergents and cleaners
-Used in the chemicals, polymers, photographic, and textile processing industries
-used in photochemicals and construction materials
STRUCTURE:
Under ideal conditions the cleaning power of BAS and Nansa HS 85/S is very similar, however Nansa HS 85/S performs slightly better in normal use conditions, due to it being less affected by hard water.
Within Nansa HS 85/S itself the detergency of the various isomers are fairly similar, however their physical properties (Krafft point, foaming etc.) are noticeably different.
In particular the point of the high 2-phenyl product (i.e. the least branched isomer) remains below 0 °C up to 25% Nansa HS 85/S whereas the low 2-phenyl cloud point is ~15 °C.
This behavior is often exploited by producers to create either clear or cloudy products.
Nansa HS 85/S is an anionic surfactant with superior detergency and excellent foaming, wetting and emulsifying properties and compatibility with a broad range of other anionic, nonionic and amphoteric surfactants.
Nansa HS 85/S is a versatile surfactant employed in numerous industries, serving especially as an intermediate in the production of liquid and powder laundry detergents, household, industrial and institutional cleaners, dishwashing detergents, car care products, hard surface cleaners etc.
APPLICATION AREAS:
-HI&I cleaning
-Emulsion polymerization
-Paints & coatings
-Laundry detergents
-Industrial auxiliaries
-Construction chemicals
-Oil fields
-Agriculture
DEFINITION:
Nansa HS 85/S is an anionic surfactant.
Nansa HS 85/S is widely used as consumer products contained in laundry detergents and kitchen detergents.
For the industrial use, Nansa HS 85/S is mainly used as emulsifiers, emulsifier for paints & coatings, and others.
Nansa HS 85/S can be described as an anionic frother with a structure that is composed of an aromatic hydrocarbon and an aliphatic radical.
In spite of the fact that these frothers have good frothing properties, their application was limited, likely because most alkylaryl sulfonate frothers contain traces of sulfur, which interfere with flotation.
EXPOSURE:
-Consumer:
The consumer can come into contact with the substance in use of the detergent, but the concentration of Nansa HS 85/S in use is below the level which would give rise harmful effects of concern.
When Nansa HS 85/S’s used as the recommended use, consumer should always read product information before use and follow the label/ use instructions.
-Worker:
The exposure can occur either in Nansa HS 85/S manufacturing facilities or in the various industrial facilities when Nansa HS 85/S is used.
Those workers in industrial operations during maintenance, sampling, testing, or other procedures could be exposed with Nansa HS 85/S.
Only qualified and trained workers handle the undiluted substance.
The manufacturing facilities offer thorough training program for employees and appropriate work processes, as well as safety equipment (goggles and gloves) in place to present an unnecessary exposure.
Safety showers and eyewash stations are accessible nearby.
Workers are required to be trained in accordance with the safety measures in the Safety Data Sheet.
-Environment:
Since Nansa HS 85/S is used extensively, Nansa HS 85/S is discharged to waste water treatment plants from industrial sites such as manufacturing, preparation, handling, storage and use of the substance as well as from consumer households.
However, the substance is readily biodegradable, so that Nansa HS 85/S is removed efficiently in waste water treatment plants.
The substance is biologically degraded in the surface water and is rapidly removed even if Nansa HS 85/S is remained slightly in the waste water.
Hence, the chronic exposure to aquatic organisms of the substance is unlikely to occur.
Furthermore, the substance dose not accumulate in the food chain, so that there is no concern of human exposure through environmental pathway.
