Lipsticks

About 50% of isopropanol use is to produce acetone. Other important synthetic uses are to produce esters of many acids, such as acetic (isopropyl acetate, solvent for cellulose nitrate), myristic, and oleic acids (used in lipsticks and lubricants). Isopropylpalmitate is used as an emulsifier for cosmetic materials. Isopropyl alcohol is a solvent for alkaloids, essential oils, and cellulose derivatives. 

The Bleeding Heart, served like a punch in a highball glass, is also subtle and stylish. Mr. Wong intends it to work well with food.The drink is the color of a twenty-three-dollar lipstick. The cocktail s name is a reference to its blood-orange ingredient. Mr. Wong has his eye on Valentine s Day, too. 

Waxes are used in water-resistant coating on cars and furniture. They are also used in lipsticks and eyebrow pencils and in liquid soaps and shampoos to give a pearlescent effect (the tiny flakes of the wax glycol distearate reflect the light). 

Effect of various formulation on viscosity and melting point of natural ingredient based lipstick...

Lipstick is one of the decorative cosmetic products that command a unique market. Lipstick contains a variety of emollients, emulsifiers, preservatives, colorants and binders [4]. The quality of lipstick is directly linked to the basic material used in the formulation [5-6]. Varying the ratio of the ingredient used in formulation determines the final product characteristic such as texture, viscosity, hardness and melting point of the lipstick [7-9]. 

A common problem in pre-formulation of the cosmetic product including lipstick is the optimisation of the mixture composition aimed to obtain a product with the required characteristic. Mixture design represents an efficient approach for solving such optimisation problem [10]. It has been proved to be an effective tool to select the best lipstick formulation [11]. 

In order to understand the relationship between the mixture component, physical properties and consumer acceptance of the lipstick, various lipstick formulations have to be produced. The physical properties of each formulation should be studied. The consumer acceptance towards the product also should be investigated. However, only a part of this work will be discussed in this paper. Here, natural waxes, oils and solvent have been used to produce natural ingredient based lipstick formulations based on the formulation suggested by the statistical mixture design. Contour plot and response surface graph were formed in order to understand the relationship between the mixture component and physical characteristic of the lipstick. 

The viscosity measurement was carried out using Brookfield Engineering Rheometer model HA DV-III equipped with small sample adapter, using spindle 28 and speed 10 rpm. Meanwhile, the melting point of the lipstick was observed with SMPI Melting Point Apparatus (Stuart Scientific). 

Natural ingredients based lipstick formulations have been prepared. The effects of the natural waxes, oils and solvent compositions on the viscosity and melting point of the lipstick have been studied. The result indicates that the viscosity and melting point of the lipstick can be manipulated by changing the composition of natural candelilla wax, camauba wax and beeswax in the formulation. Another important lipstick characteristic, which is hardness, will be studied. Consumer acceptance towards the product will be investigated. Finally, by relating the consumer data and instrumentation analysis, optimisation process will be conducted.

P.R.5 also lends itself to a variety of special applications. The list includes (decorative) cosmetics such as lipstick, eye shadow, powder, nail polish, and others. Application in this area depends on special purity requirements, and the commercially available types are tested accordingly. The pigment is listed in the European Cosmetics List. 

P.R.68 is also recommended for use in decorative cosmetics, such as nail polish, lipstick, powders, and shading creams. For these purposes, types are supplied which fulfil legal purity standards and are tested accordingly. 

P.R.57 1 is a useful colorant for a variety of special purpose media, including colored pencils and crayons. A number of countries have legally defined purity regulations concerning the use in decorative cosmetics articles, such as face powder and lipstick. The same is true for cheese casings [11], Suitable grades are commercially available, they are registered in the USA as D C Red 7, in Japan as Red No. 202. 

Another important market is in toothpaste, for which the pigment has been approved worldwide. It also lends color to lipstick and other decorative cosmetics. In the US, it is registered by FDA as D C Red 30, in Germany as C-Rot 28 according to the DFG Catalog for Cosmetic Colorants, in Japan as Red No. 226. 

Liquid crystals are mainly used for decorative purposes in cosmetics. Cholesteric liquid crystals are particularly suitable because of their iridescent color effects, and find applications in nail varnish, eye shadow, and lipsticks. The structure of these thermotropic liquid crystals changes as a result of body temperature, resulting in the desired color effect. In recent times, such thermotropic cholesteric liquid crystals have been included in body care cosmetics, where they are dispersed in a hydrogel. Depending whether this dispersion requires stirring or a special spraying process, the iridescent liquid crystalline particles are distributed statistically in the gel (Estee Lau-... 

Bismuth is used to make the drugs such as Pepto-Bismol for upset stomachs and diarrhea and in medicine to treat intestinal infections. Bismuth is used in the cosmetics industry to provide the shine for lipsticks, eye shadow, and other products. 

Lustre/pearlescent pigments have found wide application in automotive coatings, coloured plastics, synthetic leather, printing inks, ceramic products and cosmetics, e.g. nail polish, lipstick and mascara. 

In 1981, triethanolamine was reported to be an ingredient (generally at a concentration of less than or equal to 5%) in 2720 out of 22 572 cosmetic products which may be applied to or come into contact with skin, eyes, hair, nails, mucous membrane and respiratory epithelium. Small amounts may be ingested from lipsticks. Product formulations containing also monoethanolamine (triethanolamine-ethanolamine) may be in contact with the skin for variable periods of time following each application. Daily or occasional use may extend over many years (Beyer et al., 1983).

Several derivatives of xanthene are of value as colouring matters and the topic has been reviewed (B-52MI22400). For example, eosin (701 R = Br) (Acid Red 87 C.I. 45380) is used in inks, lipsticks and nail varnish in addition to its value as a dye for silk and paper. 

Some of tlie salts of bismuth are used in medicines for the relief of digestive disorders because of the smooth, protective coating the compounds impart to imtated mucous membranes. Like barium, bismuth also is used as an aid in x-ray diagnostic procedures because of its opacity to x-rays. At one time, certain bismuth compounds were used in the treatment of syphilis. Bismuth oxychloride, which is pcarlcsccnt, has found use in cosmetics, imparting a frosty appearance to nail polish, eye shadow, and lipstick, but may be subject to increasing controls. Bismuth phosphomolybdate has been used as a catalyst in the production of acrylonitrile for use in synthetic fibers and paints. Bismuth oxide and subcarbonate are used as fire retardants for plastics.
