Shower Gel
Shower gel (also called body wash) is a specialized liquid product used for cleaning the body during showers. Not to be confused with liquid soaps, shower gels, in fact, do not contain saponified oil. Instead, it uses synthetic detergents derived from either petroleum or plant sources. Body washes and shower gels have a lower pH value than the traditional soap, which is also known to feel less drying to the skin. In certain cases, sodium stearate is added to the chemical combination to create a solid version of the shower gel. History Shower gel is a derivative invention of the liquid soap, which first appeared in the 1800s. In 1865, William Shepphard patented the formula behind the liquid soap, but the product gained eventual popularity with the rise of Palmolive soap in 1898, by B.J. Johnson. Modern chemistry later enabled the creation of the shower gel, which specialized in cleaning the entire body during baths and showers. Properties Shower gels are known to consis ...

Surfactant
Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. The word ''surfactant'' is a Blend word, blend of "surface-active agent", coined in 1950. As they consist of a water-repellent and a water-attracting part, they enable water and oil to mix; they can form foam and facilitate the detachment of dirt. Surfactants are among the most widespread and commercially important chemicals. Private households as well as many industries use them in large quantities as detergent, detergents and cleaning agents, but also for example as emulsion#Emulsifiers, emulsifiers, wetting agents, foaming agents, Antistatic agent, antistatic additives, or dispersants. Surfactants occur naturally in traditional plant-based detergents, e.g. Aesculus, horse chestnuts or Sapindus, soap nuts; they can also be found in the secretions of some caterpillars. Today one of the most commonly used anionic surfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menthol
Menthol is an organic compound, specifically a Monoterpene, monoterpenoid, that occurs naturally in the oils of several plants in the Mentha, mint family, such as Mentha arvensis, corn mint and peppermint. It is a white or clear waxy crystalline substance that is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (−)-menthol, which is assigned the (1''R'',2''S'',5''R'') Cahn–Ingold–Prelog priority rules, configuration. For many people, menthol produces a cooling sensation when inhaled, eaten, or applied to the skin, and mint plants have been used for centuries for topical pain relief and as a food flavoring. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol has been demonstrated to cause a subjective nasal decongestant effect without any objective decongestant action, and administration of menthol via a nasal inhaler in humans has also been shown t ...

Microbead-Free Waters Act 2015
The Microbead-Free Waters Act of 2015 is a United States law that prohibits the addition of plastic microbeads in the manufacturing of certain personal care products, such as toothpaste. The purpose of the law is to reduce water pollution caused by these products. Manufacture of the microbead-containing products was prohibited in July 2017, and retail sales are prohibited as of July 2018.United States. Microbead-Free Waters Act of 2015. . Approved 2015-12-28. Background Over the course of the past 50 years, plastics have increasingly become a large part of people's lives all around the world. Due to the durability, versatility, and low cost of plastics, consumers and industries utilize plastics for a variety of products. However, with increased production and consumption of plastics comes an increase in plastic waste that inevitably makes its way into the ocean. Scientists estimate that there is over 150 million tons of plastic residing in the World's oceans today. Plastics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbead
Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension. They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene. They are used in exfoliating personal care products, toothpastes, and in biomedical and health-science research. Microbeads can cause plastic particle water pollution and pose an environmental hazard for aquatic animals in freshwater and ocean water. In the United States, the Microbead-Free Waters Act of 2015 phased out microbeads in rinse-off cosmetics by July 2017. Several other countries have also banned microbeads from rinse-off cosmetics, including Canada, France, New Zealand, Sweden, Taiwan, and the United Kingdom. Types Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension when they are first created, and are typically created using material such as polyethylene (PE), polyethylene ter ...

Detergent
A detergent is a surfactant or a mixture of surfactants with Cleanliness, cleansing properties when in Concentration, dilute Solution (chemistry), solutions. There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ions found in hard water. Definitions The word ''detergent'' is derived from the Latin adjective , from the verb , meaning to wipe or polish off. Detergent can be defined as a surfactant or a mixture of surfactants with cleansing properties when in Concentration, dilute Solution (chemistry), solutions. However, conventionally, detergent is used to mean synthetic cleaning compounds as opposed to ''soap'' (a salt of the natural fatty acid), even though soap is also a detergent in the true sense. In domestic contexts, the term ''detergent'' refers to househ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saponification
Saponification is a process of cleaving esters into carboxylate salts and Alcohol (chemistry), alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate and ethanol: : Saponification of fats Vegetable oils and animal fats are the traditional materials that are saponified. These greasy materials, triesters called triglycerides, are usually mixtures derived from diverse fatty acids. In the traditional saponification, the triglyceride is treated with lye, which cleaves the ester bonds, releasing fatty acid salts (soaps) and glycerol. In one simplified version, the saponification of stearin gives sodium stearate. : This process is the main industrial method for producing glycerol (). Some soap-makers leave the glycerol in the soap. Others precipitation (chemistry), precipitate t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Laureth Sulfate
Sodium laureth sulfate (SLES), an accepted contraction of sodium lauryl ether sulfate, also called sodium alkylethersulfate, is an anionic detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.) and for industrial uses. SLES is an inexpensive and very effective foaming agent.Kurt Kosswig,"Surfactants" in ''Ullmann's Encyclopedia of Industrial Chemistry'', Wiley-VCH, 2005, Weinheim. SLES, sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS), and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. It is derived from palm kernel oil or coconut oil. In herbicides, it is used as a surfactant to improve absorption of the herbicidal chemicals and reduces time the product takes to be rainfast, when enough of the herbicidal agent will be absorbed. Its chemical formula is . Sometimes the number represented by ''n'' is specified in the name, for example laureth-2 sulfa ...

Liquid
Liquid is a state of matter with a definite volume but no fixed shape. Liquids adapt to the shape of their container and are nearly incompressible, maintaining their volume even under pressure. The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Therefore, liquid and solid are classified as condensed matter. Meanwhile, since both liquids and gases can flow, they are categorized as fluids. A liquid is composed of atoms or molecules held together by intermolecular bonds of intermediate strength. These forces allow the particles to move around one another while remaining closely packed. In contrast, solids have particles that are tightly bound by strong intermolecular forces, limiting their movement to small vibrations in fixed positions. Gases, on the other hand, consist of widely spaced, freely moving particles with only weak intermolecular forces. As temperature increases, the molecules in a liquid vibrate more intensely, causi ...

Betaine
A betaine () in chemistry is any neutral chemical compound with a positively charged cationic functional group that bears no hydrogen atom, such as a Quaternary ammonium cation, quaternary ammonium or phosphonium cation (generally: Onium compounds, onium ions), and with a negatively charged functional group, such as a carboxylate group that may not be adjacent to the cationic site. Historically, the term was reserved for trimethylglycine (TMG), which is involved in methylation reactions and detoxification of homocysteine. This is a modified amino acid consisting of glycine with three methyl groups serving as methyl donor for various metabolic pathways. Pronunciation The pronunciation of the compound reflects its origin and first isolation from sugar ''beets'' (''Beta vulgaris'' subsp. ''vulgaris''), and does not derive from the Greek letter beta (β). It is commonly pronounced ''beta-INE'' or ''BEE-tayn''. Glycine betaine The original betaine, ''N'',''N'',''N''-trimethyl ...
