Alkyl (C12-C16) Alcohol Sulfate Sodium Salt is a mixture of sodium salts of alkyl sulfates derived from C12–C16 fatty alcohols.
Alkyl (C12-C16) Alcohol Sulfate Sodium Salt is an anionic surfactant widely used for wetting, detergency and foaming in shampoos, liquid soaps, household cleaners and industrial formulations.

Because Alkyl (C12-C16) Alcohol Sulfate Sodium Salt’s a mixture (variable chain lengths), exact properties vary with supplier/specification.
Alkyl sulfates (including sodium salts of fatty alcohol sulfates) belong to a class of surfactants called anionic surfactants.
These are among the oldest, most widely used surfactants because they are effective, relatively inexpensive, and have well-understood behavior.

The “alkyl (C12–C16)” descriptor means the hydrophobic (fatty) tail is a mixture of linear alkyl chains with 12 to 16 carbon atoms.
Because of the mixture, the precise behavior depends on the ratio of each chain length in a given commercial grade.

The synthesis typically involves sulfation of the parent fatty alcohol(s) (using reagents like sulfur trioxide, or chlorosulfonic acid, or other sulfating agents), followed by neutralization (e.g. with sodium hydroxide) to yield the sodium salt.

Because the head group is ionic (sulfate) and the tail is hydrophobic, the molecule is amphiphilic (i.e. has both water-loving and oil-loving parts), which gives Alkyl (C12-C16) Alcohol Sulfate Sodium Salt surface-active behavior (i.e. surfactant).
