Sulfates like sodium lauryl sulfate can be irritants; [9] [10] sulfate-free shampoos are also marketed based on this concern. [11] There are also pollution concerns with the fungicides in dandruff shampoo. [12] [13]
Radium sulfate is the most insoluble sulfate known. The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to ...
Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.
Shampoo lather in hair Bottles of shampoo and lotions manufactured in the early 20th century by the C.L. Hamilton Co. of Washington, D.C., United States. Shampoo (/ ʃ æ m ˈ p uː /) is a hair care product, typically in the form of a viscous liquid, that is formulated to be used for cleaning (scalp) hair.
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 ...
Chemical free (also chemical-free) is a term used in marketing to imply that a product is safe, healthy or environmentally friendly because it only contains natural ingredients. [1] The term is a misnomer, as all substances and objects are composed entirely of chemicals and energy.
Sulfation is widely used in the production of consumer products such as detergents, shampoos, and cosmetics. Since the sulfate group is highly polar, its conjugation to a lipophilic "tail" gives surfacant-like properties. Well known sulfates are sodium lauryl sulfate and sodium laureth sulfate. [2]
Interaction of anhydrite with hydrocarbons at high temperature in oil fields can reduce sulfate (SO 2– 4) into hydrogen sulfide (H 2 S) with a concomitant precipitation of calcite. [9] The process is known as thermochemical sulfate reduction (TSR). Hand sample of gypsum and anhydrite from diapir caprock showing "chicken wire" texture.
