Soap in the context of "Soap bubble"

Olive oil is a vegetable oil obtained by pressing whole olives (the fruit of Olea europaea, a traditional tree crop of the Mediterranean Basin) and extracting the oil.

It is commonly used in cooking for frying foods, as a condiment, or as a salad dressing. It can also be found in some cosmetics, pharmaceuticals, soaps, and fuels for traditional oil lamps. It also has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine, with wheat and grapes. Olive trees have been cultivated around the Mediterranean since the 8th millennium BC.

Marseille soap or Savon de Marseille (French pronunciation: [savɔ̃ də maʁsɛj] ) is a traditional hard soap made from vegetable oils that has been produced around Marseille, France, for about 600 years. The first documented soapmaker was recorded from the city in about 1370. By 1688, Louis XIV introduced regulations in the Edict of Colbert limiting the use of the name Savon de Marseille to olive oil based soaps. The law has since been amended to allow other vegetable oils to be used.

By 1913, production had reached 180,000 tons. Thus, in 1924, there were 122 soapmaking companies in the Marseille and Salon-de-Provence areas combined. However as of 2023, there were only four remaining, all part of an association called Union des Professionnels du Savon de Marseille (UPSM).

Hand washing (or handwashing), also called hand hygiene, is the process of cleaning the hands with soap or handwash and water to eliminate bacteria, viruses, dirt, microorganisms, and other potentially harmful substances. Drying of the washed hands is part of the process as wet and moist hands are more easily recontaminated. If soap and water are unavailable, hand sanitizer that is at least 60% (v/v) alcohol in water can be used as long as hands are not visibly excessively dirty or greasy. Hand hygiene is central to preventing the spread of infectious diseases in home and everyday life settings. Meta-analyses have shown that regular hand washing in community settings can significantly reduce respiratory and gastrointestinal infection

The World Health Organization (WHO) recommends washing hands for at least 20 seconds before and after certain activities. These include the five critical times during the day where washing hands with soap is important to reduce fecal-oral transmission of disease: after using the toilet (for urination, defecation, menstrual hygiene), after cleaning a child's bottom (changing diapers), before feeding a child, before eating and before/after preparing food or handling raw meat, fish, or poultry.

Hard soaps (Latin: sapo medicatus), also termed soda soaps in older terminology, are categorized under soaps and are typically sodium salts of fatty acids. They vary in color from white to brownish and have a fatty acid content ranging from 72 to 75%. These soaps are typically made from lower-quality fats. Hard soaps serve as the foundation for products frequently labeled as fine soaps, which are fortified with nourishing additives, perfumes, and dyes.

Sodium is a chemical element; it has symbol Na (from Neo-Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans.

Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including humans.

A soapbox is a raised platform on which one stands to make an impromptu speech, often about a political subject. The term originates from the days when speakers would elevate themselves by standing on a wooden crate originally used for shipment of soap, or other dry goods, from a manufacturer to a retail store.

The term is also used metaphorically to describe a person engaging in often flamboyant, impromptu, or unofficial public speaking. Hyde Park in London is known for its Sunday soapbox orators, who have assembled at its Speakers' Corner since 1872 to discuss religion, politics, and other topics. In the context of the World Wide Web, blogs can be used as soapboxes and are often used for promotional purposes.

Brazilian industry has its earliest origin in workshops dating from the beginning of the 19th century. Most of the country's industrial establishments appeared in the Brazilian southeast (mainly in the provinces of Rio de Janeiro, Minas Gerais and, later, São Paulo), and, according to the Commerce, Agriculture, Factories and Navigation Joint, 77 establishments registered between 1808 and 1840 were classified as "factories" or "manufacturers". However, most, about 56 establishments, would be considered workshops by today's standards, directed toward the production of soap and tallow candles, snuff, spinning and weaving, foods, melting of iron and metals, wool and silk, amongst others. They used both slaves and free laborers.

There were twenty establishments that could be considered in fact manufacturers, and of this total, thirteen were created between the years 1831 and 1840. All were, however, of small size and resembled large workshops more than proper factories. Still, the manufactured goods were quite diverse: hats, combs, farriery and sawmills, spinning and weaving, soap and candles, glasses, carpets, oil, etc. Probably because of the instability of the regency period, only nine of these establishments were still functioning in 1841, but these nine were large and could be considered to "presage a new era for manufactures".
