Cosmetic Rinse off Preparations. In certain cosmetic products, tor example hair shampoos, it is not possible to use complexing agents because of the irritation of mucous membranes. Here a low sensitivity of surfactants to water hardness is a precondition for their application. Foam formation is generally considered to be a measure of shampoo quality (Table V). With increase in water hardness the foam volume of alkyl sulfates decreases very much, whereas with the corresponding alkyl ether sulfates this decrease is relatively small. For cosmetic applications, the good skin compatibility and low irritation to mucous membranes of alkyl ether sulfates is of high importance (37). 

A-Nitrosodiethanolamine at levels of 600-7386 ppb was detected in 11 samples of cosmetics in the United States which included hand creams, face creams, shampoos, cocoa butter cream, moisturizing lotion and a make-up remover (all products listed diethanolamine and/or triethanolamine as ingredients) (Tunick etal., 1982). TV-Nitroso-diethanolamine was found in all seven cosmetic formulations one with traces (< 10 ng/g) and six at levels of 41 7 000 ng/g and in 12 of 13 lotions (seven with traces <10 ng/g and five with 14-140 ng/g) and in eight of nine hair shampoos (three with traces < 10 ng/g and live with 17-280 ng/g) in the United States (Fan et al., 1977b). Of 191 cosmetics analysed, 77 contained from 10 to more than 2000 ppb N-nitrosodiethanolamine (Elder, 1980). Westin etal. (1990) analysed 20 different suntan lotions in Israel and found that three were contaminated with 17-27 ppb TV-nitroso-diethanolamine (with traces 5-10 ppb). 

Citric acid is used in soft drinks, candies, wines, desserts, jellies, jams, as an antioxidant in frozen fruits and vegetables, and as an emulsifier in cheese. As the most versatile food acidulant, citric acid accounts for about 70 percent of the total food acidulant market. It provides effervescence by combining the citric acid with a biocarbonate/carbonate source to form carbon dioxide. Citric acid and its salts are also used in blood anticoagulants to chelate calcium, block blood clotting, and buffer the blood. Citric acid is contained in various cosmetic products such as hair shampoos, rinses, lotions, creams, and toothpastes. More recently, citric acid has been used for metal cleaning, substituted for phosphate in detergents, for secondary oil recovery, and as a buffer/absorber in stack gas desulfurization. The use of sodium citrate in heavy-duty liquid laundry detergent formulations has resulted in a rapid increase in the use of citric acid. 

Complexes with the thio-oxamate ligands NH2(CO)CSO and NH2(CS)C02, which bind through O and S, exhibit trigonal bipyramidal geometry around the zinc. The zinc complex of the 0,S-donor ligand 2-pyridinethiolate 1-oxide, known as zinc pyrithione, is a fungicide andbacteriocide much used in hair shampoos. 

Water soluble polymers are frequently incorporated in aqueous surfactant solutions in many domestic and technological applications (in formulations such as shower gels and hair shampoos), as viscosity modifiers, stabilisers and deposition aids. Water soluble polymers often interact strongly with surfactants in aqueous solution, giving rise to a rich pattern of behaviour in properties such as surface tension. The bulk properties of a variety of polymer/... 

Free formaldehyde is used in cosmetics, especially in hair shampoos, and in many disinfectants and antiseptics. The solid paraformaldehyde is used as a source of formaldehyde vapor for the disinfection of rooms. Noxythiolin, polynoxyUn, hexamidine, and taurolidine act by slow release of formaldehyde. Formaldehyde solution contains 34—38% of formaldehyde methanol as a stabilizing agent to delay polymerization of the formaldehyde. Formaldehyde gel contains 0.75% of formaldehyde and is used to treat warts. 

Dibutyl phthalate is used in pharmaceutical formulations as a plasticizer in film-coatings. It is also used extensively as a solvent particularly in cosmetic formulations such as anti-perspirants, hair shampoos and hair sprays. In addition to a number of industrial applications, dibutyl phthalate is used as an insect repellent, although it is not as effective as dimethyl phthalate.

Diethanol, triethanol, and ammonium salts are used in hand dishwashing liquids and in hair shampoos and cosmetics, where their higher water solubility and slightly acidic pH make them desirable. 

Nano wax dispersions which are prepared by a PIT process can be added to hair shampoo formulations [67]. The formulations improve the combability of wet hair and accelerate the hair drying after the wash. Wax dispersions can also be used to carry fragrance-active components. These additives can be used to give a long-lasting fragrance impression for cosmetic product applications.

Provided. Standard pH 3,5,7,9, and 11 buffers (approximate—other values near these may be used). Each member of the class should bring one or more samples of commercially available hair shampoos, conditioners, rinses, and depilatories. These may include dandruff shampoos and hair removers such as Neet or Nair. All the samples will be shared by the class. There should be enough of each to provide about 15 to 20 mL to each student.

Test procedure. Wool swatches were soiled with synthetic sebum and weighed to determine the amount of soil deposited. The swatches were then washed in a tergitometer with CMOS and soap-containing (dry hair) shampoos at varying concentrations. The swatches contained approximately 10% sebum. The temperature was 105 to 110°F, time was 30s, and a 200/1 solution-to-wool ratio and two 30-s water rinsings were used.
