• manufacture
  • Manufacture of soap began in England around the end of the 12th century. (encyclopedia.com)
  • The tax collector locked the lids on soap boiling pans every night to prevent illegal soap manufacture after hours. (encyclopedia.com)
  • Unsaponifiable constituents are an important consideration when selecting oil mixtures for the manufacture of soaps. (wikipedia.org)
  • molecules
  • Water is needed as the solvent medium in which molecules of fatty acids in oils and fats are chemically combined to create soap. (tumblr.com)
  • The insoluble oil/fat molecules become associated inside micelles, tiny spheres formed from soap molecules with polar hydrophilic (water-attracting) groups on the outside and encasing a lipophilic (fat-attracting) pocket, which shields the oil/fat molecules from the water making it soluble. (wikipedia.org)
  • Similarly to sodium, potassium also can react with long fatty acid tails to make soap molecules. (wikipedia.org)
  • The slippery feeling experienced when using soap with soft water occurs because soaps tend to bind to fats in the surface layers of skin, making soap molecules difficult to remove by simple dilution. (wikipedia.org)
  • surfactants
  • Household uses for soaps include washing, bathing, and other types of housekeeping, where soaps act as surfactants, emulsifying oils to enable them to be carried away by water. (wikipedia.org)
  • Soaps are mainly used as surfactants for washing, bathing, and cleaning. (wikipedia.org)
  • often
  • Traditional shaving soap is often sold as a round puck, either with a rounded bottom intended for use with a shaving scuttle or a flat bottom for use in a mug. (wikipedia.org)
  • Due to their lower moisture content, hard soaps often do not require preservatives. (wikipedia.org)
  • Paste
  • potassium soaps make a paste, gel or liquid soap. (wikipedia.org)
  • When the paste was taken off the market as dangerous, Spencer "began manufacturing his own product in his laboratory, a mild soft-soap solution, which he used to dilate the cervix and loosen the conceptus in the first stage of his procedure. (wikipedia.org)
  • water
  • After the soap is made, most of the water is removed by evaporation. (tumblr.com)
  • Too much water will result in soap that 'shrinks' when the finished bars are dried. (tumblr.com)
  • Water solutions of approximately 30% Sodium Hydroxide (lye) by weight are usually used in making bar soaps. (tumblr.com)
  • Our SBM Crafters Soap Calculator will compute the minimum amount of water by weight to use for any bar soap formula recipe input there. (tumblr.com)
  • Similarly, common soap does not work as well as potassium-based soap in hard water where calcium replaces the sodium, making residual insoluble "scum" due to the insolubility of the soap residue. (wikipedia.org)
  • To be an effective cleaning agent, soap must be able to dissolve in water. (wikipedia.org)
  • Potassium soaps dissolve and make salt water soap work better than sodium in salt waters such as in seawater. (wikipedia.org)
  • In places that do not have fresh water or need to conserve it, cleaning can be done with the use of salt water and saltwater soap. (wikipedia.org)
  • After oil is removed from the whiskers by the shaving soap and brush, water can more easily penetrate the whiskers. (wikipedia.org)
  • As one of the most simple hydroxides, it is frequently utilised alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students. (wikipedia.org)
  • Similar to the hydration of sulfuric acid, dissolution of solid sodium hydroxide in water is a highly exothermic reaction in which a large amount of heat is liberated, posing a threat to safety through the possibility of splashing. (wikipedia.org)
  • The resulting soft water is more compatible with soap and extends the lifetime of plumbing. (wikipedia.org)
  • made
  • Soap was also made by the Celts, ancient inhabitants of Britain . (encyclopedia.com)
  • Soap made without dye is a dull grey or brown color, but modern manufacturers color soap to make it more enticing to the consumer. (encyclopedia.com)
  • Most products made by Vermont Soap are certified to USDA organic standards by Vermont Organic Farmers (VOF) , the certification program of NOFA-VT . (vermontsoap.com)
  • solution
  • A 3-10% solution of potassium hydroxide (KOH) gives a color change in some species of mushrooms: In Agaricus, some species such as A. xanthodermus turn yellow with KOH, many have no reaction, and A. subrutilescens turns green. (wikipedia.org)
  • largely
  • Among cartridge razor users, shaving soap has largely been displaced by canned shaving foam or gel, but hard shaving soaps are still utilized by users of double-edge safety razors and straight razors. (wikipedia.org)
  • lather
  • A hard shaving soap is used with a shaving brush to create lather for shaving. (wikipedia.org)
  • Shaving soap is produced like a traditional soap with an ingredient selection oriented to producing a stable, slick lather. (wikipedia.org)
  • reaction
  • In perhaps its most well-known reaction, aqueous KOH saponifies esters: KOH + RCOOR' → RCOOK + R'OH When R is a long chain, the product is called a potassium soap. (wikipedia.org)
  • oils
  • Proportions of oils can be varied and many other oils and fats are available to experiment with, each contributing something different to your handcrafted soaps. (tumblr.com)
  • This will leave some 'extra' oils in the finished soap and will allow the oils' properties to be expressed in the soap. (tumblr.com)
  • This, along with careful selection of the oils used in the recipe, will affect the feel and qualities of the soap produced. (tumblr.com)
  • Choosing a particular oil to be the superfatting oil and adding it to the new soap just before pouring it into the mold will emphasize the qualities of that just added oil above the general mix of oils used. (tumblr.com)
  • First choose the amounts and proportions of the different oils and fats you will be using in your soap recipe. (tumblr.com)
  • Use .15 cc scoop per pound of oils in C.P Soap. (pinemeadows.net)
  • Such soaps are also used as thickeners to increase the viscosity of oils. (wikipedia.org)
