Fischer projection of D-erythrulose
Fischer projection of D-erythrulose

D-Erythrulose (also known as erythrulose) is a tetrose carbohydrate with the chemical formula C4H8O4. It has one ketone group and so is part of the ketose family. It is used in some self-tanning cosmetics, generally combined with Dihydroxyacetone (DHA). Image File history File links D-erythrulose_Fischer. ... Fischer projection of D-glucose In chemistry (particularly organic chemistry and biochemistry), a Fischer projection is a two-dimensional representation of a three-dimensional organic molecule by projection. ... A tetrose is a monosaccharide with 4 carbon atoms. ... Carbohydrates (literally hydrates of carbon) are chemical compounds that consist of monosaccharide sugars of varying chain lengths and that have the general chemical formula Cm(H2O)n or are derivatives of such. ...

Erythrulose is a natural based keto-sugar which reacts with the amino acids in the keratin protein on the outer or dead surface layer of the skin. (the stratum corneum layer of the epidermis) This non-toxic reaction produces a temporary browning effect called the Maillard reaction. This is not a stain or dye, but rather a chemical reaction that produces a color change on all treated skin. The reaction is similar to the browning effect seen when a cut apple slice is exposed to oxygen. Keto can refer to. ... In chemistry, an amino acid is any molecule that contains both amino and carboxylic acid functional groups. ... Microscopic view of stained keratin. ... The stratum corneum (the horny layer) is the outermost layer of the epidermis, and comprises the surface of the skin. ... Epidermis could refer to: In plants, the outermost layer of cells covering the leaves and young parts of a plant, see plant dermal tissue system. ... The Maillard reaction is a chemical reaction between an amino acid and a reducing sugar, usually requiring the addition of heat. ...


The brown color is comparable to the appearance of a UV based suntan. Because the skin continually exfoliates itself, losing thousands of dead surface skin cells each day, the tan hue is temporary. The tan appearance typically lasts from 2 to 10 days depending on application type, and skin condition.


Erythrulose is a clear to pale yellowish liquid, which naturally occurs in red raspberries. According to the manufacturing company Centerchem, inc. [1] Erythrulose is manufactured from the aerobic fermentation of the bacterium Glconobacter followed by extensive multi-step purification. Categories: Move to Wiktionary | Stub | Chemistry ...


Erythrulose and dihydroxyacetone are very similar in composition, and both react much the same way on the skin surface. Erythrulose produces a lighter and slower developing tan, taking 24 to 48 hours to complete development. When used alone, it fades faster then a DHA based sunless tan. Some people feel the final tone of erythrulose is slightly redder, and less bronze, then the DHA based tan. It may be less drying to the skin surface, helping provide a smoother fading tint. When combined with DHA, the resulting sunless tan is said to last longer, fade better, and provide a more cosmetically pleasing color tone. In sunless tanning products, it is incorporated at 1% to 3% levels. Fischer projection of dihydroxyacetone Dihydroxyacetone is a triose carbohydrate with chemical formula C3H6O3. ... Sunless tanning (also known as indoor tanning) refers to applying chemicals on the skin to produce an effect similar in appearance to a traditional suntan. ...


Not all users devolpe a tan coloration from erythrulose, some may find that their fading is more uneven and blotchy, when this ingredient is used. Because of the added cost associated with this ingredient, some manufacturers feel it is an inefficient additive to the sunless tanning product line.


Individuals, who are sensitive to DHA, may be able to use erythrulose as a skin safe self-tanning replacement. Erythrulose is more expensive, and difficult to obtain. Because DHA and erythrulose are very similar in composition, it is not unusual for someone to be reactive to both DHA and erythrulose.


Erythrulose reacts on the skins surface and does not seem to penetrate beyond the dead surface skin layers. Side effects are limited to occasional contact dermatitis in sensitive individuals. In many suspected cases of sensitivity, the reaction is related to other ingredients in the self-tanning product such as preservatives, dyes, fragrances or plant based additives and extracts. Dermatitis, also known as eczema, is a skin irritation characterized by red, flaky skin, sometimes with cracks or tiny blisters. ... A preservative is a natural or synthetic chemical that is added to products such as foods, pharmaceuticals, paints, biological samples, etc. ...


Though Erythrulose appears safe for use by all indications, it is not currently approved by the FDA as a self tanning agent. The United States Food and Drug Administration is the government agency responsible for regulating food, dietary supplements, drugs, cosmetics, medical devices, biologics and blood products in the United States. ...

Erythrulose is found in many plants and lichens and is produced in Germany by modern microbiological fermentation.
Erythrulose is more stable and has lower reactivity with the proteins in the skin.
Erythrulose tans the skin giving a natural and homogeneous brown / bronze appearance, whereas Dihydroxyacetone often produces a mottled and irregular tanning, which can be caused by not sufficiently cleaned skin, with differing pH or inhomogeneous application.
