The tricks are called in the chemical Cosmetics Skin Cleansing .
These are products that have a primarily aesthetic function, created to enhance the exterior beauty of the body and mask imperfections.
These color cosmetics should provide a small dose, not to allergic reactions and remain unchanged. The colors used are insoluble pigments and lakes, often used in conjunction with other substances such as opacifiers, pearlescent or glitter.
POWDER
The powders are designed to give a natural color to the face and neck.
They consist of a support (excipient), colors and additives.
The other ingredient is found in greater quantities than the other components and serves as an adhesion, to maintain contact with skin, clothing and towels.
These functions are ensured by the presence of substances such as kaolin, silicon dioxide, starch, titanium dioxide, zinc oxide, calcium oxide, zinc carbonate and calcium, zinc and aluminum stearate, talc, magnesium carbonate.
dyes are insoluble pigments and lacquers.
additives are perfumes, pearlescent substances, antimicrobial agents, surfactants, fixatives, moisturizers, UV filters.
The powders are sold in powder or compact.
Those are made of powdered magnesium silicate, kaolin, zinc stearate, magnesium silicate, talc, iron oxide, fragrance. Those compact contain mainly titanium dioxide, magnesium stearate, magnesium silicate, mica, iron oxide, preservatives, antioxidants, talc, isopropyl isostearic, paraffin oil, perfume.
BELLETTI
The cosmetics are intended to color the skin more sharply than the powders.
may be dry (powder or compact), suspended in hydrophilic (pigments in milk or cream O / A, as the foundation), hydrophobic in suspension (suspended pigments A / O), hydrocolloid suspension.
I FARD generally contain pigments, preservatives, antioxidants, talc, alcohol, lanolin, dimethyl polysilicon, paraffin oil, perfume.
The O / W emulsions as a makeup base containing glyceryl monostearate, cetyl alcohol, stearic alcohol, paraffin oil, cetyl stearyl octanoate, octyl palmitate, talc, pigments, propylene glycol, polietossisorbitano, xanthan gum, aluminum or magnesium carbonate, glycerin , preservatives, fragrance.
ROSSETTI AND COSMETICS LIPS OF
cosmetics lip may have an aesthetic and a protective function.
The lipsticks are anhydrous pasta shaped stick, consisting of an excipient, coloring and additives. The other ingredient is given by body wax, fats and oil bodies. Among the most widely used body wax is beeswax, which has plastic qualities, an ideal melting point and a high number of hydroxyl, which makes it more polar than others. They can also be used carnauba wax, candelilla wax, paraffin wax and the ozocherite.
Among the fat bodies are cocoa butter, cetyl alcohol, lanolin and its derivatives, oils idrogrenati.
Among the bodies we find the wax, castor oil, oleic alcohol and mineral oils.
In lipsticks are also fixers, pigments, paints and dyes soluble. Among the fixers are bromoderivati, iodo-derivatives, chloro-derivatives. They have bright colors and durable.
lacquers and pigments are the most used. These are salts of carboxylic or sulfonic acids linked to alkaline earth metal insoluble excipient.
soluble dyes are designed to standardize the color, but must be included at concentrations higher than 0.1% because those teeth and are dispersed in the area of \u200b\u200bapplication.
Among the additives are dispersants of fixers, tetrahydrofurfuryl alcohol esters, esters of sugar alcohols. Among the antioxidants vitamin E acetate is recalled, the butylated hydroxytoluene (BTH), butylated hydroxyanisole (BHA), tocopherols.
Other substances that may be present UV filters are substances, soothing scent.
I lipsticks fluids differ in the use of fixers only partially soluble in a movie. So do not contain insoluble pigments and lacquers.
The emollient lip are similar to classic lipsticks or fluid, but do not contain dyes (or contain a very small part). There are instead of cocoa butter, avocado oil, egg yolk oil, lecithin, vitamin F.
ENAMELS
glazes, cosmetics or nails are used to beautify, protect and igienicizzare nails. These coatings, which give strength and shine, smoothing, slightly abrasive, which remove small scratches dall'unghia, whitebait, pasta or a pencil full of white pigments and wax bodies; epichiniolitici, alkaline agents which smooth the keratin of skin, hardening, strengthening the nail, paint strippers, which are used to remove the paint without damaging the nail and tissue attached; spotting for stains of tobacco, Ink and plants.
TALC
The powders are mixtures of metal organic and inorganic powders.
tetrasilicato Talc is made of magnesium hydroxide, kaolin is a tetrasilicato aluminum hydroxide, zinc oxide is a white absorbent and astringent; Tiñana oxide is a white powder on the metallic titanium, high hiding power, and the basic magnesium carbonate is a white powder with high absorption, the diatomaceous earth is made up of alkaline earth metal silicate is a powder and very light with high absorption, the metal components are organic stearate magnesium, zinc and aluminum, with absorbing function of sebum.
hygienic powders are of plant or animal origin, with power and greasy slide. Require the addition of preservatives in the preparation, to remedy the lack of fermentability. These include the
lycopods, a yellow powder that comes from Licopodium clavatum, greasy, light and sticky, the Iris, a beige powder with absorbent; starch, especially that of rice, absorbing body moisture and fermentable (with the defect to form colloidal solutions but they can clog pores), the albumin content of milk, a white powder with moisture absorbing properties without giving colloidal solutions, synthetic polymers and semi-synthesis, including vinyl polymers, acetylated starch.
