Excipients & Chemicals for the Pharmaceutical Industry
Reliable excipients and active ingredients for tablets, capsules, syrups and topical products, supplied to pharmaceutical manufacturers across Pakistan.
Pharmaceutical Industry Chemicals Supplier in Pakistan
A tablet is far more than its active ingredient. Around it sit binders that hold it together, fillers that give it size, lubricants that help it leave the press, coatings that protect it and sweeteners that make a syrup pleasant to swallow. These are known as excipients, and their quality has a direct effect on how a medicine performs.
Humayun Wellchem Trading Concern supplies pharmaceutical manufacturers in Pakistan with a wide range of excipients, vitamins and processing chemicals. Here is where each is used in dosage form manufacturing.

Tablet Binders & Fillers
Fillers give tablets the right size and weight, and binders hold the powder together during compression so tablets do not crumble.
Chemicals used: Micro Crystalline Cellulose, Lactose, Di-Calcium Phosphate, Hydroxy Propyl Cellulose, Starches, Maltitol
Flow Aids & Lubricants
Glidants help powders flow evenly into the tablet press, while lubricants prevent sticking to punches and dies.
Chemicals used: Silicon Dioxide, Talcum Powder, Stearic Acid, Magnesium Oxide
Coatings & Capsules
Film coatings mask taste, protect moisture-sensitive drugs and give tablets their colour and shine. Gelatin forms hard and soft capsule shells.
Chemicals used: Titanium Dioxide, PEG, Carnauba Wax, Gelatin, Food Colors
Syrups & Oral Liquids
Sweeteners and polyols make medicines easier to take, especially for children. Buffers and preservatives keep liquids stable and free of microbes after opening.
Chemicals used: Sorbitol, Glycerin, Sodium Benzoate, Citric Acid, Tri-Sodium Citrate, Methyl Paraben, Propyl Paraben
Effervescent & Chewable Tablets
Acid and carbonate pairs release carbon dioxide when dropped in water. Sugar-free sweeteners give chewables a pleasant taste.
Chemicals used: Citric Acid, Sodium Bicarbonate, Tartaric Acid, Aspartame, Acesulfame K, Sorbitol
Vitamins, Minerals & Supplements
Vitamins and mineral salts are the active ingredients of multivitamins, ORS sachets and calcium supplements.
Chemicals used: Ascorbic Acid (Vitamin C), Vitamin E, Vitamin A, Calcium Carbonate, Potassium Chloride, Magnesium Sulphate
Excipients Shape How a Tablet Performs
The choice of filler, binder and disintegrant decides how hard a tablet is, how quickly it breaks down and how well it survives packing and transport. Microcrystalline cellulose gives strong tablets by direct compression, lactose is a versatile filler for wet granulation, and silicon dioxide keeps fine powders moving. Getting the combination right reduces rejects on the production line.

Frequently Asked Questions
What are pharmaceutical excipients?
Excipients are the inactive ingredients in a medicine. They help with manufacturing, stability, taste, appearance and how the active ingredient is released in the body. Common examples are fillers, binders, lubricants, coatings, sweeteners and preservatives.
Do you supply pharmacopoeia grade (BP/USP) materials?
Several of our materials are available in pharmaceutical grades. Please share the grade and monograph you require (for example BP, USP or EP) and we will confirm availability and documentation for that specific product.
Which filler is best for direct compression?
Microcrystalline cellulose is one of the most widely used direct compression fillers because it compresses well and produces hard tablets. It is often combined with lactose or dicalcium phosphate depending on the formulation.
Can HWTC support new product development?
Yes. Contact our team with your formulation requirements and we can suggest suitable excipients from our range and arrange samples where available.
