دفاتر الذكريات

لكل واحد منهم دفتر
أجهزه منذ لحظة اللقاء الأولى
أعرف أنه حين يغادر
سأحتاج أن أقول على صفحاته ما أريد
شئ من العتاب
كلام كنت أخشى اذا قلته له أن يغضب
بعض تخاريف الأصدقاء
بعض المشاعر التي ان بقيت داخلك قتلتك
عندما تنتهي صفحاته.. أطوي الدفتر و أركنه على رف كتبي
أتركه في مكان تقع عليه عيني يوميا
لأسلم عليه كلما رأيته

نور الأمكنة

مصطفى حميدو

دون أن يصف من يعرفها بهاءها
و بالكلمات ينحت جمالها
حضورها يكفي
نور المكان اذا تشرف بطلة منها
عرف الجميع أي جمال أناره
أي بهاء أضاءه
الواصف عادة يصف الجمال
يخلده ذكرى للسنين
لكنها
ان زارت مكانا
ظل المكان يحدث بحسنها
و أضحت الأسفار في الدرج القصي مركونة
فالمكان يحدث عن حالها
يقول للخلق
نوري الذي يسلب لبكم
هو في الحقيقة نورها
في يوم كذا
في ساعة كذا
في دقيقة كذا
خلد نورها ذكراها
جعل المكان تحفة
يحدث التاريخ عن حال من زاره و جمالها
صباحك ورد

Where to find Free Cosmetic Formulas?

 

Perry Romanowski

Source: http://chemistscorner.com/where-to-find-free-cosmetic-formulas/

One of my goals is to create a website that gives starting formulas to anyone who is looking for one. I’m modelling it after the Open Source Software movement and dubbing it Open Source Formulating (or something like that). Essentially it will be a place where people can find and exchange formulas. Almost a recipe swap.

But until I get that going, I thought it would be useful to provide links to places where you can get formulas to start already. Here is what I’ve got so far. The list will continue to grow. Please feel free to add other links in the comments if there are sources that aren’t mentioned.

General Cosmetic formulation lists

Cosmetic Bench Reference – A list of hundreds of supplier formulas searchable by type, ingredient trade name and more. Suppliers for all materials included. Requires registration.

C & T 2008 Skin Care formulary – Formulas for creams, lotions, cleansers, and masks.

C & T 2006 C&T Skin formulary – Formulas for creams, lotions, cleansers, and masks.

Happi formulary– Wide range of formulations from suppliers of cosmetic raw materials.  Also some formulation of household products if you’re looking for that.  No registration required

Personal Care Magazine – Nice set of easily accessible formulas.  No registration required.

Innovadex – Requires registration but has hundreds (maybe thousands) of formulas from suppliers.

SpecialChem4Cosmetics – They have an excellent starting formulations selector.  Includes skin care, hair care, sun care, toiletries, fragrance, and makeup.  Requires registration.

Merck formulations – Hundreds of cosmetic formulations and some other interesting things like insect repellent.  No registration required.

Google Patents – This takes a little digging but if you do a search of the patents on any kind of formula that you want to make, you can find example formulas in the ‘claims’ section of most any patent on the subject.

Google Books – Google has a number of books that list some cosmetic formulations.  Many you can get listed for free.

Supplier Formularies

Grant Industry Formulary – Lots of cosmetic formulas including make-up, creams & lotions, Sunscreens, Skin treatments, Hair care, and more. Over 100 formulas

Brenntag Personal care formulas – This company has a nice list of starting formulas for hair, skin and color cosmetics.  Not an extensive list of formulations but about 100 formulas.

Colonial Chemicals formulas – A number of cosmetic formulas.  Also some household cleaner and metal working lubricants too.

Croda Formulary – Some excellent starting formulas using materials from Croda.  Formulas in all types of different products and includes some “green” or Natural formulations.  Registration is required (a little annoying).

Dow Corning formulations – Not organized in the best manner for cosmetic chemists but a good number of formulations that feature silicone as a significant component.

Dupont Tate & Lyle formulations – Offers a number of skin care and color cosmetic formulations.  Also has a couple of hair care product formulas.

Stepan formulary – One of the biggest surfactant suppliers in the business.  They have some excellent starting formulas for cleansing products and emulsions.

HallStar Formulations – A searchable list of formulations with particular focus on suncare and skin care.  It is handy that it allows for searching by keyword including INCI names.

IGI Cares formulas – A short list of some interesting formulas that focus on petrolatum and waxes.

Jeen International formulary – A small list of formulas but covering a wide range of product categories including bath and shower, sun care, hair care, skin care, and color cosmetics.

Kobo formulations – A rather extensive list of formulas focused on color cosmetics and sunscreens.  Formulas are all freely available.

Lubrizol formulations – A wide variety of formulas in all categories of personal care and cosmetic products.

Lipo Formulary – A very slick compilation of formulas for everything ranging from facial care, to general skin care, hair care and color cosmetics.  The descriptions provided for each formula are helpful.

R.T. Vanderbilt formulas – Cosmetic formulations in 5 different categories including skin care, sun care, color cosmetics, cleansing, and treatments & grooming.  Includes reactive hair products like relaxers and perms.

Seppic Formulations – One of the best features is that you can search formulas by keyword and also they have a formula selection tool that allows you to choose by application, texture, claim, and target consumer.  Nicely organized.

DIY / Hobbiest formulations

DIY Cosmetics Formulary – Recipes for makeup, shampoos, cleansers and soap.

The Herbarie Formulary – More recipes for making personal care products.   Focuses on natural or green technologies.  More of a home crafter DIY site than a cosmetic industry site.

MakingCosmetics.com– A nice list of recipes for all types of cosmetics from creams, lotions, sun products and color cosmetics.  Formulas are available in a number of formats and list % weights and kitchen measurements.  Nicest thing is that it doesn’t require registration to get a formula.  Nice going Making Cosmetics!

Make Your Cosmetics – A wide range of formulations organized in alphabetical order.  Each formula tells approximately how long it will take to produce and has comments from other makers as to what they thought.  Has a number of lip and facial care formulations.

Cosmetic Formulator – A defunct website but through the magic of the Internet Wayback machine you can still access the formulations.  Includes a number of powdered makeup formulas and just a couple of skin care creams.

Realize Beauty formulations – A variety of formulations with descriptive procedures for making them.  Not a long list but some nice starting formulas for soap, conditioner, toothpaste and more.

Ingredients to die for Formulary – 70+ formulations for both hair and skin applications.  Most formulas are for skin care products.

Personal Formulator – A small list of formulations but includes some products for pets.

Skin Essential Actives – Some nice additional resources on the site (like a formula calculator) in addition to a range of skin care starting formulations.

Karen Gilbert recipes – Formulations with videos to show how they are made.  These are more like cooking recipes than formulations but the demonstrations are excellent.  Nicely produced.

LotionCrafter – Not a lot of formulas but a nice collection of facial care, skin care, hair care, and spa products.  Also, sells raw materials so you are able to make the products.

العاصفة ضد تقدم الجيش شمال حلب: التوقيت السئ

الهجوم الاخير على شمال حلب و الذي ادو الى سيطرة الجيش على عدد من القرى ثم انسحابه الى باشكوي و تمركزه فيها قد يكون عملا استطلاعيا الا ان المشكلة ان التوقيت كان سيئا. الجيش كان قد سيطر على باشكوي تل مصيبين  و دوير الزيتون رتيان و حردتنين  ثم انسحب تحت الضغط الى باشكوي و احتفظ بدوير الزيتون. التوقيت السئ مرتبط اساسا بحالة الطقس.

الكل كان يعرف ان عاصفة ثلجية تقترب و ان اي تقدم سيصطدم بغياب التغطية الجوية بمجرد قدوم العاصفة و بالتالي رجحان الكفة لناحية المسلحين بسبب التفوق العددي و قدرة الحشد المرتبطة بالحدود المفتوحة مع تركيا.

تغريبة الشمال السوري

الصورة في الشمال السوري لا تقول الا حقيقة واحدة: ما يحصل هناك هو تطهير عرقي كامل الاركان. اضحت داعش وسيلة او لنقل اداة لتنفيذ مشاريع كانت تطل برأسها خجلا طوال السنوات السابقة. اتت داعش و اضحت تلك المشاريع تظهر بوضوح اكثر يوما بعد الاخر. دعونا نوضح. الاكراد استفادوا من داعش في التمدد و في اكتساب نوع من الشرعية عبر تظهيرهم في الاعلام كمحاربي داعش و الطرف المقبول من الجميع لهذه المهمة.

 عين العرب كانت محطة رئيسية في هذا التظهير. صحيح ان المدينة دمرت الا ان مكاسب الاحراد كانت كبيرة جدا. فمن ناحية هم اكتسبوا سمعة محاربة داعش و من ناحية اخرى تمددوا حتى يقال اليوم ان هدفهم القادم هي مدينة تل ابيض. السيطرة على تل ابيض سيخلق لهم تواص جغرافي بين الحسكة و ريف حلب. الخطوة التالية ستكون حتما جرابلس قم اعزاز و كله تحت غطاء جوي اميركي ليصبح السؤال: هل هناك عمليا منطقة حظر جوي في الشمال السوري؟

Considerations in Pre-formulation Stage of Solid and Semi-Solid Dosage Forms (Al01-2015)

Paper no. Al01-2015

Mustafa Hamido| 02/02/2015

Solid and semi-solid dosage forms are the most widely marketed and administered drugs nowadays. Almost 70% of the administered drugs are in solid states. It is preferred by the pharmaceutical companies due to its high safety, low cost and marketing issues.

Pre-formulation is a stage of development during which the physicochemical properties of drug substance are characterized. Before the formulation of a drug substance into a dosage form, it is essential that to be chemically and physically characterized. Pre- formulation begins with calculation/prediction ‘in silico’ of many of the important physicochemical characteristics of the API. Literature search of similar type of compounds is the second step of pre-formulation process.

Pre-formulation influences on selection of the drug candidate itself, selection of formulation components, API & drug product manufacturing processes, determination of the most appropriate container closure system, development of analytical methods, assignment of API retest periods, the synthetic route of the API and toxicological strategy.

The most important function of pre-formulation stage is solid state characterization which determines the next step in the formulation work of the studied API. Physical properties of the studied API influence on its physical and chemical stability. It influences on the rout of administration, delivery system and the drug activity. Moreover, Chemical stability of the drug is affected by the physical properties. Crystal morphology, polymorphism, amorphous forms and hygroscopicity are usually studied. In addition, solubility, salt form, melting point, dissolution of the API are also studied.

Certain properties are studied in pre-formulation stage of the solid dosage forms. These properties relate mainly to the ability of the powder to flow in the compressing machine and subsequently its compressibility. They influence on the dissolution rate of the API, stability, bioavlaibility, degradation rate and purity.  The studied properties include particle size, its distribution, its surface area and porosity. It includes also true density, flowability, API color, electrostaticity, caking and polymorphism.
