After drying, if you notice any dull spots or if the surface seems a bit dry, apply a thin layer of cooking oil (such as vegetable oil or flaxseed oil) to the inside of the cookware. Wipe off excess oil with a paper towel to ensure a light coating. If possible, place it back over the heat for a few minutes to allow the oil to bond with the cast iron, enhancing the seasoning.
- For a long time, the only material used to make capsule shells was gelatine. Gelatine is obtained from the skin and bones of various animal species, especially pigs and cattle. Due to strict regulations on the use of gelatine caused by emerging diseases such as TSE (Transmissible Spongiform Encephalopathy), which includes BSE (Bovine Spongiform Encephalopathy), the search for a substitute for gelatine was encouraged.
Plant-based capsules have also been available on the market since 1998. With HPMC, consumers have a completely safe, plant-based product at their disposal, so that vegans or vegetarians and people who abstain from gelatine due to their religion also have an alternative to gelatine capsules.
HPMC capsules can withstand high temperatures and high humidity and have a low inherent moisture content. This makes the capsule shells suitable for storing moisture-sensitive ingredients. They therefore protect their contents from all kinds of fluctuations, such as temperature fluctuations and humidity. HPMC capsules can therefore be stored well in all climate zones. In contrast, gelatine capsule shells have a lower water content. They therefore quickly become brittle at low humidity.
Despite the many advantages of HPMC capsules, gelatine capsules are still the most commonly used type of capsule in the pharmaceutical industry. One reason for this is probably the lower price. - Hydroxyethyl cellulose, often abbreviated as HEC, is a modified natural polymer derived from cellulose, the major component of plant cell walls.

In nasal sprays, HPMC helps to improve the viscosity of the formulation and promote the absorption of the drug through the nasal mucosa. In topical formulations, HPMC can act as a stabilizer and emulsifying agent to improve the stability and shelf-life of the product.
- In addition to its thickening properties, HPMC also acts as a binder in many applications. It can improve the adhesion of different components in a formulation, helping to create a strong and uniform final product. HPMC is often used as a binder in construction materials such as cement and plaster, where it improves workability, adhesion, and water retention.
- Purification: HPMC is washed several times with hot water, and filtered.
- In the food industry, HPMC acts as a stabilizer, emulsifier, and thickener. It is particularly useful in sugar-free confectionery to replace fat and provide texture. Food-grade HPMC must comply with strict regulations, ensuring safety and quality.
- In addition to construction, redispersible polymer powders also find applications in the manufacturing of paints and coatings. By incorporating these powders into paint formulations, manufacturers can create products that are more resistant to water, chemicals, and abrasion. This is especially beneficial for exterior paints, which are exposed to the elements and require a high level of protection.

- One of the most significant advantages of MHEC is its ability to form viscous solutions at low concentrations. This property makes it an ideal thickener and stabilizer for many products, including cosmetics, pharmaceuticals, and food products. In cosmetics, MHEC can be used as a thickener in creams, lotions, and shampoos, providing a smooth texture and preventing separation of ingredients. In pharmaceuticals, it can be used as a binder or disintegrant in tablets or capsules, ensuring proper release of medication. In food products, MHEC can be used as a thickener or emulsifier in sauces, dressings, and beverages.
Cellulose is a linear homopolymer consisting of repeating β-d-glucopyranosyl units linked via (1,4) glycosidic bonds. In its pure form, the straight chains are bound closely together by multiple intermolecular hydrogen bonds and van der Waals forces, producing a water-insoluble fibrous or crystalline substance which is relatively inert. The EFSA ANS Panel assessed recently the absorption, distribution, metabolism and excretion (ADME) of celluloses (EFSA, 2018) and draw the following conclusions concerning non-herbivore mammals: cellulose is not absorbed intact in the gastrointestinal tract of animals and humans but is fermented during its passage through the large intestine by the microbiota, with the limited production (9% of the administered dose in the rat) of short-chain fatty acids (mainly acetic acid and succinic acid), hydrogen, carbon dioxide and methane.
