Fatty Amines. Fatty amines are the most important nitrogen derivatives of fatty acids. They are produced by the reaction of fatty acids with ammonia and hydrogen. They are the bases for the manufacture of quaternary ammonium compounds used as fabric softeners and biocides. Fatty amine oxides are mild to the skin with good cleaning and foaming properties and find application as a shampoo ingredient. The above mentioned products are but some of the oleochemical derivatives from coconut fatty acids (5). 

Other coco-based surfactants are sulfosuccinates formed by the reaction of coco fatty alcohol with maleic anhydride and further reaction with sodium sulfite or bisulfite. This product possesses good foaming properties, is compatible with soap, and is a good lime dispersant. It is used in toilet soap formulation, shampoos, hand cleaning pastes, and for scouring raw wool. Its ether variant, with 2-4 moles ethylene oxide, forms intense, finely structured foam and is used in combination with ether sulfate in baby shampoos and bath preparations. 

For simple cleaning shampoos, adequate rheological properties can generally be obtained by the same methods used for lather sufficiently high primary surfactant plus the same secondary surfactants listed above as lather modifiers. 

Extensive use of C12 anionic surfactants is attributed to the physical properties (solubility, wetting, cleaning, etc.) of the alkyl sulfate, in the form of sodium or ammonium salts, which provides desirable attributes of a shampoo. In fact, by controlling the degree of ethoxylation of the alcohol prior to sulfation and utilizing appropriate neutralizing bases, a wide variety of shampoos representing many consumer needs can be formulated. ... 

In contrast to the benefits discussed above, cationic surfactants are generally incompatible with anionic surfactants, the primary surfactants used in shampoo formulations, which further limits their applications. The cleaning and foaming properties of cationic surfactants are considerably inferior to those of the anionics, and another major downside is the weighing-down effect on hair. Because of these limitations and compatibility issues, cationic surfactants are not used very often in shampoo formulations, and applications are limited mainly to conditioning, lubricating, and antistatic benefits in conditioners. 

Surfactants, in general, are excellent cleaners and rinse easily from the hair with no issues of buildup. It is also expected that surfactants do not precipitate onto the hair or in hard water, nor should they leave a residual sticky or tacky feel on the hair surface. Whereas ALS is the principal primary surfactant used in the United States, other countries use SLES (with 2- or 3-mole EO). There is a trend to use sodium pareth sulfate, a synthetic version that performs similar to SLES. Because of their excellent cleansing properties, combinations of these surfactants are used in many shampoo formulations to ensure effective cleaning. 

Personal Care. The addition of PEO provides a silky feel to solid and liquid products. This imique lubricious property has been successfully exploited in formulation of razor strips (202,203) and in shampoos, detergents, and other personal care applications. The combination of water solubility and the ability to produce films and other devices by thermoplastic processing enables the use of the PEO in flushable articles (204-207). PEO has also been used as an antimisting agent in personal care and cleaning formulations (208) and has been shown to enhance the deposition of active ingredients to the hair and skin, as well as to act as a foam enhancer (209). Fundamental investigations have examined the interaction of PEO and surfactants in aqueous solutions (210-213). 

Af-Fatty P-aminopropionate has an equal number of anionic and cationic groups. A number of iV-fatty P-aminopropionates, under the trade name Deri-phat (Henkel products), has been used in shampoo formulations. Deriphats, as shown structurally in Table 2 [45], either singly or in combination, have shown promise in shampoo formulations. A shampoo with good cleaning and foaming properties has been obtained by combining A-dodecyl-p-alanine and a cationic surfactant (dioctadecyl dimethylammonium chloride). The presence of Deriphats in a shampoo formulation could reduce eye irritation and sting... 

Cationic surfactants. Cationic surfactants are known for their anti-microbial efficacy. However, depending on their structure, due to only moderate skin compatibility, and in some cases poor foaming properties, they are rarely used as the main cleaning agent in skin and hair cleansing products. Nevertheless, they are often used in low concentrations in hair conditioners and treatment preparations. They are also used in shampoos, to... 

The careers of chemists and chemical laboratory technicians consist of the study of the composition, structure, properties, and changes of material substances. The fruits of their labor are many. The following items are just a few that have resulted from chemists and laboratory technicians studying chemistry batteries, plastics and clothing fibers, pharmaceuticals and medicines, pesticides and herbicides, clean water and air, fertilizers, soaps and shampoos, and perfumes and deodorants. How do we begin a study of chemistry We begin by understanding what is meant by each item in the definition.
