Skin cream

Cosmetics and Soaps, One to five percent lecithin moisturizes, emulsifies, stabilizes, conditions, and softens when used ia products such as skin creams and lotions, shampoos and hair treatment, and Hquid and bat soaps. Siace the iatroduction of Capture ia 1986, liposomes produced from phosphohpids ate commercially available worldwide (36,37). [Pg.104]

Cysteine is used as a reductant for cold wave treatment in place of thioglycoHc acid. A/-Lauroylarginine ethyl ester [48076-74-0] is appHed as the hydrochloride as a preservative. Urocanic acid [104-98-3] hich. is derived from histidine is used in skin cream as a uv absorber (235). [Pg.297]

Skin Irritation. Fine broken filaments often irritate the skin, occasionally causing transient itching and rashes. The back of hands and wrists and neck areas tend to be most sensitive. Protective clothing and barrier skin creams help prevent the fiber from reaching the skin and causing discomfort. [Pg.7]

Glycerin is used in many skin creams and medicines, such as eye and ear drops, poison ivy creams, suppositories, and contraceptive jellies. It is also used as an emollient (skin softener) in soaps. [Pg.58]

The past decade has seen a dramatic increase in the number of reported applications of neural computing in pharmaceutical formulation [29-32]. Applications now cover a variety of formulations—for example, immediate and controlled release tablets, skin creams, hydrogel ointments, liposomes and emulsions, and film coatings. The following examples are by no means exhaustive, but they show where neural computing has been used successfully in modeling formulations. [Pg.692]

Sun worshipers and those who work outside can protect themselves from ultraviolet exposure with skin creams that contain UV-absorbing molecules. The UV-absorbing molecule in the first sunscreens was PABA, para-aminobenzoic acid. However, this compound may have toxic effects of its own. The UV-absorbing components of current sunscreens are derivatives of cinnamic acid and benzophenone. [Pg.486]

Trivial burns are sometimes produced by the accidental handling of hot glass. These may be smeared with vaseline or skin cream and covered with clean or preferably sterile linen. Blisters should not be broken. Tannic acid jelly is not recommended. [Pg.28]

Alternatively, a sequence of pervaporation steps can be used to remove the reaction water (Figure 4.10). The reaction solution is pumped through a first fixed-bed reactor and afterwards a pervaporation module is used to remove the water at 80 °C. The solution is subsequently cooled to 60 °C and passed through a second reactor unit. After the next pervaporation step the water content is lowered to 0.2 wt%. By this process, isopropyl myristate is produced from myristyric acid. This and other esters of isopropyl alcohol are used in soaps, skin creams, lubricants and greases [43],... [Pg.89]

A circulating tank is recommended, the motion being required to prevent skinning, creaming and sedimentation. Screening or filtration is also provided to retain air bubbles, and any coagulum. The tank contents need to be maintained at a constant temperature and the tank is equipped with a lid to prevent evaporation of water when not in use. [Pg.177]

Ceramide is now included in some skin creams which are claimed to be beneficial to the skin, preventing drying and reducing the effects of ageing. Linoleoyl-ceramide is present in the skin where it restricts water permeability, preventing excessive water loss from the skin. [Pg.243]

Decreased mobility or immobility and incontinence are risk factors for the development of pressure ulcers. The use of appropriate barrier skin creams may protect against the development of pressure sores, especially in bedridden patients. [Pg.211]

Emulsions are mixture of two (or more) immiscible substances. Everyday common examples are milk, butter (fats, water, salts), margarine, mayonnaise, skin creams, and others. In butter and margarine, the continuous phase consists of lipids. These lipids surround the water droplets (water-in-oil emulsion). All technical emulsions are prepared by some kind of mechanical agitation or mixing. Remarkably, the natural product, milk, is made by organisms without any agitation inside the mammary glands. [Pg.173]

Emulsions are one of the most important structures prepared specifically for a given application. For example, a day cream (skin cream) has characteristics and ingredients different from that of a night cream. One of the main differences between emulsions is whether oil droplets are dispersed in the water phase, or water drops are dispersed in the oil phase. This can be determined by measuring their conductivity because conductivity is higher for the O/W than for the W/O emulsion. Another useful property is that O/W will dissolve water while W/O will not, thus showing that W/O or O/W may be chosen depending on the application area. Especially in the... [Pg.174]

The criteria for W/O emulsions are that it is miscible with oil that is, if the emulsion is added to an oil, a new but diluted W/O emulsion is obtained. In some skin creams, the W/O type emulsion is preferred, especially to obtain an oil-like feeling after application. [Pg.176]

The human skin is a rather complex structure, which protects the body against the environment. The aim of the different cosmetics is to repair and restore the original balance of elements in skin structure. Cosmetic preparations would need to consider any reaction between them and the components of the skin. Skin creams are known to be composed of a variety of ingredients, which are based on end use (hands, feet, face, hair, etc.), and some speciality products that are applied to the skin to repair effects such as dryness. We will now consider some recipes for skin creams. Since the number of personal care emulsion creams is very large, only a few typical examples are given here. A variety of emulsion skin care products are found commercially that claim to exhibit properties for nurturing and protecting the skin. [Pg.194]

Materials in a colloidal state are frequently preferred in industrial processing operations because their large surface areas per unit volume enhance chemical reactivity, adsorptive capacity, heat transfer rates, and so on. Therefore, one cannot overlook the importance of the flow behavior and properties of colloids since they exert a significant influence on the performance, efficiency, and economy of the process. Note that some examples of this (e.g., ceramic processing, electrophoretic display devices, and food colloids) were mentioned in the vignettes presented in Chapter 1. In addition, one often uses the flow properties and behavior of the products as measures of the microstructure (or, morphology ) of the products and as a means of quality control (e.g., printing inks, toners, paints, skin creams, blood substitutes,... [Pg.145]

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 ...

White tea is especially potent in that it is has three times as much antioxidant polyphenols as green or black tea and has been shown to be 100% more effective in mopping up free radicals that cause skin to sag. Some of the world s top cosmetic companies are becoming very interested in white tea for skin creams, and the result is that high-grade white tea is becoming even more rare than before. [Pg.382]

Alternatively, prepare a list of advertising slogans based on chemical concepts, such as Use Fluoride Toothpaste for Strong Teeth or Alpha Hydroxy Skin Cream Removes Wrinkles. Draw advertisements using color to evoke emotion, as discussed above, but also explain the chemical concepts involved in the slogans. Apply the principles of good composition to your advertisements. [Pg.23]

Alpha hydroxy acid is an organic acid with mild abrasive properties. However, it is difficult to believe that any skin cream removes wrinkles. [Pg.23]

The latest trend in lip gloss is tiny—about 100,000 times smaller than the width of a human hair. In skin creams, sunscreens and cosmetics, the hot new ingredients are nanoparticles. These extremely small molecules are about one-billionth of a meter in size. When molecules get this small, they act differently than larger or"normal"-sized molecules. [Pg.72]

One of the most famous nanoparticles is the buckyball, a molecule made up of 60 carbon atoms arranged in a soccer-ball shape. Some skin creams now include buckyball molecules. Another widely used nanoparticle is zinc oxide. For years, swimmers applied zinc oxide as a thick sunscreen paste, but the new nano-sized version of the compound is so small that it looks transparent when slathered on as sunblock. The makers of these products say the nanoparticles can reflect light and fight off damage to skin cells better than normal-sized particles. A few cosmetics manufacturers are experimenting with nanoparticles in eye shadow and lipsticks to see if the tiny molecules can produce different colors or new visual effects like iridescence, where colors seem to constantly change.
