طريقة تصنيع Dettol علمياً "كما تصنعه الشركة الأم

السادة إخوانى الأعزاء ...
أقدم لكم اليوم أول مساهماتى بالمنتدى وهى عبارة عن الطريقة العلمية الصحيحة المؤيدة بالمستندات لتصنيع منتج Dettol كما تصنعه الشركة الأم وهى شركة إنجليزية إسمها Reckitt Benckiser
... وأرجو الإستفادة للجميع

[CENTER]INTRODUCTION TO DETTOL CONCEPT
Dettol (also called parachlorometaxylenol, or PCMX) is the name of a commercial
liquid antiseptic belonging to a product line of household products manufactured by
Reckitt Benckiser and marketed in South Asia, Africa & Middle East, Asia Pacific,
Europe, Australasia.
Chemical structure of chloroxylenol
the key ingredient which defines its unique antiseptic property is an aromatic chemical
compound in chemistry known as chloroxylenol (C8H9ClO). This makes up 4.8% of
Dettol's total mixture, with the rest composed of pine oil, isopropanol, castor oil soap,
caramel, and water. Because several of the ingredients are insoluble in water, Dettol
produces a white emulsion of oil droplets when diluted during use. It has a characterisitic
phenolic odour similar to trichlorophenol and the explosive compound known as
trinitrotoluene (TNT). Apart from its low toxicity and low metal corrosivity, it is also
relatively cheap compared to other disinfectants and is effective against gram positive
and gram negative bacteria, fungi, yeast, mildew and even the frightening "super-bug"
MRSA, thus giving it a broad spectrum of antimicrobial action. It is able to kill 98% of
microbes in just 15 seconds as shown in agar patch studies, by disrupting the bacterial
cells' membrane potential, drastically affecting its ability to produce Adenosine
triphosphate and thus leading to its rapid death.
Dettol can also be used to treat acne in small quantities. The bottle cap also doubles as a
container for pouring increments of 10ml for its various uses. However, like other
household cleaners, it is still poisonous and should not be ingested. In an extreme case, a
42 year old English man died from Dettol overexposure in May 2007. [1] Overuse of
Dettol can also cause bacterial resistance, but the risk of infection can be reduced
considerably by using it in addition to soap and water.

An indicative formula for BIOCROL PCMX :
Biocrol PCMX 2%
Pine oil 4%
Castor oil soap (30%) 12% (Castor oil +caustic soda+ water)
Deionized water 82%
Clarification
• CASTOR OIL SOAP : Add water to saponify(*)( convert oil into soap ) the
castor oil with caustic soda till it reaches a concentration of 30%.
• When facing difficulties in dissolving Biocrol PCMX then it is suggested to
dissolve it in IPA 95%(isopropyl alcohol ) and add it to Pine Oil then mix it with
the already prepared Castor Oil soap 30% and add the rest of the Deionized
water(**).
(*)Saponification : A reaction in which an ester is heated with an alkali, such as sodium
hydroxide, producing a free alcohol and an acid salt, especially alkaline hydrolysis of a fat or oil
to make soap.
(**)Deionized water (DI water or de-ionized water; also spelled deionised water is water that
lacks ions, such as cations from sodium, calcium, iron, copper and anions such as chloride and
bromide. This means it has been purified from all other ions except H3O+ and OH−, but it may
still contain other non-ionic types of impurities such as organic compounds. This type of water is
produced using an ion exchange process. Deionized water is similar to distilled water, in that it is
useful for scientific experiments where the presence of impurities may be undesirable/CENTER]
