Face lotions

Rheology is of major importance in processing operations in industry. The rheological behavior of process streams and dispersions determines the pumping and transportation costs, the ease of mixing operations in reactors, and the quality of the final product in many cases. What we do not often realize is that it is also one of the factors that determine the esthetic and sensual appeal of certain products, especially in the case of food products and cosmetics Differences in the fed of a face lotion or a skin cream or the consistency of a ketchup can make or break the market for the product ...

Also, Heinig et al. (1997) quantified cetyltrimethylammonium bromide in face lotion by CE with indirect detection (dodecylbenzyldimethylammonium as chromophore) and without pre-treatment. The influence of an organic modifier and electrolyte chromophore was examined obtaining conditions that permit the separation of alkyl and dialkyl ammonium compounds. In reversed-phase LC, benzyltrimethylammonium was used as a chromophore. Comparison of both methods gave results with better reproducibility for LC and similar detection limits for both methods.

The agent of choice for scabies is permerthrin 5% (Elimite) cream. Alternative agents in subjects who cannot use permethrin are crotamiton 10% (Eurax) and oral ivermectin (Stromectal) 200 mcg/kg as a single dose. To initiate the treatment with permerthrin, the skin should be scrubbed in a warm soapy bath to remove the scabs. The permerthrin lotion should then be applied to the whole body, avoiding the face, mucous membranes, and eyes, and left on for 8 to 14 hours. A single application eradicates 97% of scabies. All close contacts should be treated appropriately. The pruritus associated with scabies may persist for 2 to 4 weeks because of the remnants of mite parts in the skin.

Coumarin has also found use in toothpastes, antiperspirant deodorants, bath products, body lotions, face creams, fragrance creams, hair sprays, shampoos, shower gels and toilet soaps (Cohen, 1979 Lake, 1999). It has been used in detergents as a brightener or bleaching agent (Perone, 1972). 

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). 

The elbow test involves applying products to the inside of the elbow up to six times per day for three weeks. This is a sensitive area of skin, and easily defined, which is important since this is a selfapplication test. This test is useful for products such as body lotions, etc., and also as a preliminary to a face test, where the skin is more sensitive. Each panellist serves as their own control the test material is applied to one elbow and the control material applied to the other. The panel is balanced according to sex, hand dominance, and initial skin grades of reaction. One half of the panel has the dominant hand allocated to the test material, and the other half has their dominant hand allocated to the control material. The levels of irritation elicited by the test and control treatments are compared. Subjective comments are also taken into consideration. At intervals throughout the treatment period, each site is assessed for visible signs of irritation, for example, erythema and dryness. 

For some of the effects the concentration in the products is most important, for example, the local tolerance on the skin and eye. For some of the other effects it is necessary to estimate the presumed use by a normal or perhaps an eager user and the total amounts are more adequate. Guidance to relevant exposure estimation can be found in part 6 of SCCNFP. Safety evaluation of finished products in the notes of guidance.3 The European cosmetics industry has, for example, estimated the exposure levels to be 0.8 g/day of face cream, 1-2 g/day of general cream and 8-16 g/day of body lotion for a female user.10 It is also important to predict the use of the special product and the expectations from the single user. Groups of users with especially sensitive skin are important to take into account. 

Cosmetics are natural or synthetic toiletry products that are used to maintain hygiene and include externally applied products used to enhance appearance. This class includes dental products, bath supplies (e.g., bubble baths, body washes, and bath beads), powders, lotions, lipsticks, perfumes, colognes, shampoos, depilatories, and hair coloring/waving products. Most of these products contain alcohols, aromatic hydrocarbons, perborates, and anionic and nonionic surfactants. Use of cosmetics is as old as civilization itself. Centuries ago wealthy women would apply the white lead pigment known as ceruse to their faces to appear fashionably pale - sometimes with lethal consequences. Women also used belladonna alkaloids like atropine to dilate pupils to enhance the attractiveness of the eyes in the late nineteenth century.

In the cosmetics industry, finely dispersed fillers, are used as abrasives (toothpaste, scrub cosmetics), for their light reflecting properties (sunscreen lotions), for their dehydrating and astringent effect (kaolin in face masks), for their cooling effect (zinc oxide in sunburn lotion), and as cosmetic color additives and extenders (makeup). The many different applications require an extensive range of filler properties. 

Cleansing creams and lotions are detergent-based or emulsified oil systems that are designed primarily for the removal of surface oil, pollutants, or cellular debris along with makeup from the face and neck areas. Most emulsified cleansing creams are manufactured similar to cold creams but modified to enhance their debris-removal capability. They usually contain from 15 to 50 percent oils (e.g., mineral oil, vegetable oils, fatty esters, and propoxylated oils) with limited quantities of waxy materials. 

The first liquid foundations were known as neck and arm whiteners. They were developed for use in the theater and were early attempts to improve the characteristics of applied face powder. Early pharmaceutical methods used to develop improved foundations included combinations of calamine lotion, zinc oxide, glycerin, and water. Until the 1940s, foundations were in the form of nonflowing and very greasy pastes and creams (often called grease paint ). The cosmetic industry soon thereafter used different types of emulsifiers and thickeners combined with...
