Best of acne: Avoid aggresive cosmetic's compounds to sensitive skin

Acne is a common condition that affects both men and woman at almost any age. It is most common associated with adolescence.
The cause of acne involves many factors, with genetics playing a key role. Acne develops in pores and oil glands in the skin. The cells in pores form keratin that accumulates and blocks the opening. The oil glands continue to produce oil(sebum). Microbacteria is common and lives in the pores. This bacterium is called Propionibacterium acnes. The bacteria in the pore flourishes in the environment of blockage and increased presence of sebum. The result is a cascade effect causing the skin to become inflamed and swollen, forming a pimple or cyst.
Other causes of acne vary in each individual. In females, it is not uncommon to have pre-menstrual flares secondary to hormones called androgens. Many medications are also associated with acne. Examples include testosterone, barbiturates, lithium, anticonvulsants and tropical, inhaled or systemic corticosteroids. Finally, mechanical irritation such as vigorous brushing of the upper hairline or friction from a bra strap, football helmet or headband may cause acne.
In general, people with darker skin tend to have less severe acne compared to lighter akinned individuals. Darker skin is more compact with larger oil glands and more structurally defined pores. These characteristics are usually protective against severe acne. When acne is present, the cause are identical to lighter skinned individuals. Darker skin, however, tends to hyperpigment after pimple has resolved. When treating this condition, be careful not to irritate the skin, as this may worsen the darkening.
For years, people have thought that greasy foods, soda, milk, chocolate or iodine products may cause acne. This approach is controversial but not without some merit. Some people are exquisitely sensitive to food and medications. Food, for the most part, is not a major cause of acne.
Each individual's skin is uniquely sensitive to various cosmetics or products. Always use "oil-free makeup". The term non-comedogenic is use in lieu of "oil-free" on many products. Water base products are not necessarily oil free. Many of these products contain oil. If your skin is sensitive to cosmetics, use name brand lotions, gels or creams and check the label. When applying cosmetics, minimize finger contact with the jar or bottle; this may contaminate the product with bacteria. Use sable brushes and make sure your brushes and sponges are clean. A sable brush may be cleaned through the gentle dishwasher cycle.
Pink and red cosmetic shades draw attention to irritated skin. Keep cosmetic color tones neutral with skin tones or warm browns. Makeup artists mix a green tinted makeup with regular foundation to help conceal red ares. Use this sparingly. Another hints is to try to dab concealer on top of your foundation. Blend the edges out and then set this with pressed powder. Powders can be used when applied with sable brush. This reduces skin irritation. Powders are important as they can camouflage the red to purple areas and adsorb excess oil in oily skin individuals. Avoid indescence in the powder. Indescence is achieved by ground up mica that can clog the pores and cause acne. It is adviseable to choose a powder of matte finish.
Examine the contents of the makeup and avoid the following compounds: acetylated lanolin, algae extract, algin, butyl stearate, carrageenan, cocoa butter, hexadecyl alcohol, laurel alcohol, laureth 4, isocetyl stearate, isopropyl esters, isopropyl isostearate, isopropyl myristate, isopropyl palmitate, isostearyl isostearate, myristyl lactate, myristyl myristate, octyl stearates, oleyl alcohol, potassium chloride, PPG 2 myristyl propionate, red algae, sodium chloride, sodium lauryl sulfate, solutan 16, steareth 10 and wheatgerm oil.
Keep in mind that hair products may aggravate acne. Watch the use of styling gel, mousse, pomades and hair spray.

Best of biodiesel: Advantage and disadvantage

Advantage of biodiesel:
- High cetane rating of almost 6
- Very good inherent viscisity
- 11% Oxygen content, ensuring clean combustion with 50% less soot emission
- Almost sulfur free at max. 0.01% content
- Good CFPP rating of approx. - 10 Celcius degree
- Biodegradable
- Recommended for use in water protection areas
- Non toxic, non hazardous, trouble free transport and storage.

Disadvantage of biodiesel:
- The oxidation process
In the initial phase of chain reaction, the oxidation process releases free radicals that in turn combine with oxygen from the atmosphere to form unstable peroxide radicals. They tear away neighboring hydrogen atoms, reating unstable hydroperoxides as well as other free radicals, which starts the chain reaction again and creates a self feeding chain. Over the ensuing reactions, the reactions, the remaining unstable hydroperoxides decompe into aldehydes, ketones and acids and then, in other reactions, create polymers. Letting the reaction progress unhindered leads to severe damage: stickness at the nozzles, clogged filters, deposits, corrosion or even brittle hoses, seals and other plastic or rubber components. Therefore antioxidants needed to captured the free radicals as they form, thereby effectively interruping the chain reaction - the key to absolutely stable biodiesel.
- Needed special Polyamide(i.e VESTAMID, for highly stable line systems) compound for adapting automotive components to biodiesel. There is a good reason for this restriction: the solvent nature of certain chemical properties in biodiesel can damage plastic and rubber components in the engine and fuel systems.

Best of biodiesel: Biodiesel additives

Biodiesel additives:
- Alkaline(Sodium, Potassium) metylate as catalyst(initiator in the transesterification process) for efficiency and productivity transesterification.
- Antioxidants for effective stabilization and storage.
In every phase of lifecycle, from manufacturing to storage to combustion in the engine, biodiesel is subjected to oxidative influences. It starts with the so called radical degradation reactions that caused undisered polymers, aggresive acids and peroxides. Biodiesel ages a lot faster than petroleum diesel and its use by date is very often exceeded by the time the biodiesel finally makes it to the end user. Therefore additives are needed to effectively keep shelf life up and cost down.
- Defoamers to enhance multifuntional diesel additive packages.
Excessive foaming, reduced filling capacity, longer filling times and thus reduced productivity at the fuel pump. These are the main reasons why deafomers have become a key component in multifuntional diesel additive packages. This applies to conventional fuels and even more so to fuels with a 5% biodiesel content, which represents the bulk of biodiesel sales.

Best of biodiesel: Transesterification from vegetable oil

From vegetable oil to high-tech fuel: Transesterification
Source material for biodiesel is usually derived from widely available vegetable oils, depending on region:palm oil, coconut in tropical regions, soybean in the USA, rapeseed(canola) in northern Europe.
Vegetable oils - just as an animal fats - are made from triglycerides, i.e. the combination of trivalent alcohol glycerol with three fatty acids. Their molecular structure precludes their use for conventional combustion diesel engines in their pure form. The key is to replace the trivalent glycerol with a monovalent methanol: this transforms the thick vegetable oil into a biodiesel with excellent flow characteristics. And all it takes is a simple chemical reaction: transesterification with methanol and a small quantity of an alkaline catalyst, Sodium methylate solution in methanol and Potassium methylate solution in methanol have become the industry's preffered choice. The state of vegetable oil determines the efficacy and cost efficiency of these catalyst. To prevent undesired side effects, such as soaping or increase catalyst requirement, the crude oil should be purified to water content of max. 0.3% or a free fatty acid content of max. 1%. In addition to biodiesel, transesterification also yields glycerol as a valuable by-product for pharmaceutical and cosmetics industry.
