Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees.The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).ron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.
* A surfactant. * Also known as Sodium Lauryl Phenyl Sulfonate. Functions: Sodium Dodecylbenzenesulfonate is comprised of substituted aromatic compounds and used as a surfactant in a variety of cosmetics and personal care products, primarily cleansing products such as bath soaps and shampoos. 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.
Disodium laureth sulfosuccinate is a chemical found in hair and skin products. Quite simply, itâs a de-greasing, emulsifier, and foaming agent used in many shampoos and other cleaning products much like SLS and SLES.LS is another common chemical found in cosmetic products such as shampoos, scalp treatments, and body washes. The biggest difference between the two chemicals is that sodium lauryl sulfate is more chemically modified and contains smaller molecules that can penetrate and irritate the skin.
