SOAP MANUFACTURING BY HOT PROCESS

SOAP MANUFACTURING BY HOT PROCESS



You are invited to read my previous article " HOW TO MAKE SOAP BY COLD PROCESS" before they proceed with this. That widely described the raw materials for soap making which is common for both processes. The basic differences between cold and hot soap-making processes are, In the cold process, it uses its own heat to generate the saponification process while in the hot process you have to provide an external heat source to complete the saponification process before the soap mixture pours into the mold. The main advantage of the hot processed soap is lower cure time compared with the cold process, many soaps can be used the following day. It means that the full saponification process takes place during the cooking. 

Equipment needed for hot process

  • A crock pot
  • 02 large containers or buckets, made from plastics or glass to measure lye
  • Plastics cups
  • Weighing scale
  • Spatulas(wooden or rubber)
  • Safety goggles
  • An apron
  • Gloves
  • Molds
  • Oil papers
  • Well ventilated working place
Procedure
  • Dissolve the lye in water. Never pour the water into the lye. This results in a dangerous reaction. Stir the water with a rubber/wooden spatula while sprinkling the lye. Continue this until the lye is fully dissolved in water. During the process, a fume is generated.  
  • In a separate pot melt, the oil provided
  • Next, mix the lye solution with the liquid oil and stir until trace
  • Cook the soap batter at 80°C to 100°C for 1.5-2.0 hours. Stir occasionally and avoid the overheating of the soap mixture
  • Pour the batter into molds
  • Allow cooling
  • Demolding
  • Soap cut into bars

HOW TO MAKE SOAP BY COLD PROCESS

 HOW TO MAKE SOAP BY COLD PROCESS What is soap? Soap is a consumer good that we need to maintain good hygiene daily. The history of soap is extended to 2200 BC. Soap helps to prevent the spreading of diseases, and clean the clothes and goods. During the Covid-19 virus, soap did a tremendous job against spreading it.  The major constituents of soap are oil, alkali(base), and water.Apart from that, there are several miscellaneous ingredients that are added to the soap mixture to obtain scent, color, and texture. Soap act as a cleaning agent. It comes to the market with different physical natures such as cubes, bars, powders, and liquids. Manufacturing of soap is done by using 02 processes. Namely Cold Process Hot Process In this blog article, we are discussing the cold process. The basic soap recipe for the cold process is to produce 4kg of laundry soap Oil or fat          -     2.75kg Alkali/Base     -     370g Water  ...

Natural Rubber

 The natural rubber has a vegetative origin. It is extracted as latex from the bark of the Hevea tree. Natural rubber latex is a polymer. The monomer or building unit of natural rubber latex Isoprene. The molecule consists of thousands of Isoprene units, joined end to end resulting in poly Isoprene or Natural rubber.  The natural rubber polymer is almost 100% Cis-1,4 poly Isoprene and the  average molecular weight (M W)  is in the  3.4 × 10 6    range Natural rubber tends to crystallize spontaneously at low temperatures or when it is stretched, because of its high structural regularity. Low-temperature crystallization cause stiffening of the polymer, but it can be easily reversed by warming. Crystallization of natural rubber results in high tensile strength, and resistance to cutting, tearing, and abrasion. Composition of Field Natural Rubber Latex Material                       ...

RECYCLING OF TIRE RUBBER

  RECYCLING OF TIRE RUBBER In 1840, Charles Goodyear invented the process "Vulcanization" to convert soft natural rubber into a hardened form by the formation of cross-links in between rubber molecules, bridged by Sulphur atoms. Simply Vulcanization can be defined as the "heating of rubber with sulfur" which is an irreversible process and is predominantly used to produce automobile tires. The global consumption of natural rubber for the tire industry is 76% of all the natural rubber produced globally. According to the year 2019 statistics, over 3 billion tires are manufactured annually, worldwide. The tire is a composite product of natural rubber, polymer derived from non-renewable petroleum products, various chemicals, steel, and fabrics and is designed for use in a single generation. Once the tire is worn out, it becomes an industrial waste. There are serious concerns about the disposal of used tires in the environment such as possible fire hazards(tire fires), in...
