Cosmetics astringents

Copper(I) carbonate (Cu + CO Cu Oj) is known as cuprous carbonate since coppers ion is +1 copper(II) carbonate (Cu + CO — CuCO ) is known as cupric carbonate, which is also known as the green copper mineral malachite, used in pigments, as an insecticide, as a cosmetic astringent, and as a plant fungicide to prevent smut.

As of 1991 in the United States, OTC antiacne preparations may contain only a few active dmgs, for example, sulfur [7704-34-9] resorcinol acetate [102-29-4], resorcinol [108-46-3], salicylic acid [69-72-7], and some combinations (52). OTC anti-acne constituents maybe included in a variety of conventional cosmetic preparations, which then become OTC dmgs. These include lotions, creams, solutions, facial makeups, facial cleansers (including abrasive cleansers), and astringents. Products must contain the specified dmgs at the designated concentrations. Compositions of antiacne products have beenpubhshed (53). 

The family Hamamelidaceae consists of 26 genera and about 100 species of shrubs or tress known to contain tannins and iridoids. The leaves are alternate, simple, and often palmately lobed. The flowers are small and appear in spikes. The fruits are woody, capsular, and scepticidal. In Western medicine, the dried leaves of Hamamelis virginiana (hamamelis, British Pharmaceutical Codex, 1963), yielding not less that 20% of alcohol (45%)-soluble extractive, have been used as astringents for the treatment of hemorrhoids. Hamamelis water (British Pharmaceutical Codex, 1969) made from the stems has been used as a cooling application to sprains and bruises and as a styptic remedy. It is also used in cosmetics and as active ingredient of eye lotions. 

Zinc oxide occurs in nature as mineral zincite. It is the most important zinc compound and has numerous industrial applications. Zinc oxide is the pigment in white paints. It is used to make enamels, white printing inks, white glue, opaque glasses, rubber products and floor tiles. It is used in cosmetics, soaps, pharmaceuticals, dental cements, storage batteries, electrical equipment, and piezoelectric devices. Other applications are as a flame retardant, as a UV absorber in plastics, and a reagent in analytical chemistry. A major application of zinc oxide is in the preparation of most zinc salts. In medicine, the compound is used as an antiseptic, an astringent and a topical protectant.

An amber-yellow coloured oil with a pleasant characteristic odour. Particularly suited to greasy complexions as it rapidly penetrates the skin, having an astringent and circulatory stimulating effect in addition to its nutritive properties. When diluted with other carriers like sunflower or grapeseed the blend may benefit conditions like acne. Cosmetically hazelnut oil is used in sun filter lotions and creams, soaps, shampoos and other hair products. Its main fatty acids are oleic (70-84%), linoleic (9-19%) and stearic (1-4%). It has been reported to cause immunological urticaria (a skin condition also known as hives) and in common with other nut oils there is a possibility of anaphylactic shock. 

Hyperhidrosis Astringents reduce sweat production, especially aluminium chloride hexahydrate (20%) in ethyl alcohol (95%).Antimuscarinics (topical or systemic) may help and high local concentrations can be obtained with iontophoresis. Minimally invasive sympathectomy is occasionally necessary complications include compensatory hyperhidrosis elsewhere.Temporary remission (16 weeks) is achieved by injection of boiulinum toxin, most effectively in the axilla. Treatment better in theory than in practice the volume of sweat dilutes the topical application the characteristic smell is produced by bacterial action, so cosmetic deodorants contain antibacterials rather chan substances that reduce sweat production. 

The aluminum hydroxide gel referred to in the USP 28 is used in cosmetics as an emollient, filler, humectant, a mild astringent, and viscosity controlling agent. In pharmaceutical preparations it is used as an adsorbent, and as a protein binder. It is also used therapeutically as an antacid, and as an abrasive in dentrifrices. It is not, however, used as a vaccine adjuvant. 

Sodium borate is used in pharmaceutical applications similarly to boric acid (see Boric Acid). It has been used externally as a mild astringent and as an emulsifying agent in creams. It has also been used in lozenges, mouthwashes, otic preparations (0.3% w/v), and ophthalmic solutions (0.03-1.0% w/v). Sodium borate has additionally been investigated in the prevention of crystal formation in freeze-dried solutions. Preparations of sodium borate in honey have historically been used as paints for the throat, tongue, and mouth, but such use is now inadvisable because of concerns about toxicity in such applications, see Section 14. Sodium borate is also used in cosmetics such as moisturizers, deodorants, and shampoos. 

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.

However, several problems limit the use of these valuable compounds. The problem of lack of stability should first be resolved before using natural polyphenols in pharmaceutics or cosmetics. These compounds oxidize very quickly, leading to the appearance of unwanted colors and to a decrease in activity. Furthermore, many natural polyphenolic compounds present limited water solubility. This low solubility, often associated with low intestinal permeability and instability in the gastrointestinal tract (pH, enzymes, and other nutrients), results in insufficient oral bioavailability. Finally, the astringent and bitter taste of many polyphenolics should be masked before use in food or for oral pharmaceutical forms.
