Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...

Historically, most classes of technical documentation lacked universal conformity for format, content and structure. Standards are being developed to redress this through bodies such as the International Organization for Standardization(ISO), which has published standards relating to rules for preparation of user guides, manuals, product specifications, etc. for technical product documentation.
In aqueous cleaners, surfactants (e.g., laundry detergent) are often added to permit dissolution of non-polar compounds such as oils and greases. An ultrasound generating transducer built into the chamber, or lowered into the fluid, produces ultrasonic waves in the fluid by changing size in concert with an electrical signal oscillating at ...

Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12-C 15, C 12-C 13 and C 10-C 13, for detergent use. [1] The C n H 2n+1 chain is unbranched. They are mainly produced as intermediate in the production of surfactants, for use in detergent. Since the 1960s, LABs have emerged as the dominant precursor of ...
