Sodium Lauroyl Sarcosinate
Sodium lauroyl sarcosinate ( INCI), also known as sarcosyl, is an anionic surfactant derived from sarcosine used as a foaming and cleansing agent in shampoo, shaving foam, toothpaste, and foam wash products. This surfactant is amphiphilic due to the hydrophobic 12-carbon chain ( lauroyl) and the hydrophilic carboxylate. Since the nitrogen atom is in an amide linkage, the nitrogen is not pH active and is neutrally charged in all aqueous solutions regardless of pH. The carboxylate has a pKa of about 3.6 and is therefore negatively charged in solutions of pH greater than about 5.5. pH-sensitive vesicles can be prepared using this surfactant with another cationic or water-insoluble amphiphiles such as 1-decanol. Addition of a mixture of equal parts of sodium lauroyl sarcosinate and the non-ionic surfactant sorbitan monolaurate (S20) to a buffered water:ethanol solution led to the formation of micelle-like aggregates, even though neither surfactant formed micelles when presen ...

International Nomenclature Of Cosmetic Ingredients
The International Nomenclature of Cosmetic Ingredients (INCI) are the unique identifiers for cosmetic ingredients such as waxes, oils, pigments, and other chemicals that are assigned in accordance with rules established by the Personal Care Products Council (PCPC), previously the Cosmetic, Toiletry, and Fragrance Association (CTFA). INCI names often differ greatly from systematic chemical nomenclature or from more common trivial names and is a mixture of conventional scientific names, Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages.

Amphiphile
In chemistry, an amphiphile (), or amphipath, is a chemical compound possessing both hydrophilic (''water-loving'', polar) and lipophilic (''fat-loving'', nonpolar) properties. Such a compound is called amphiphilic or amphipathic. Amphiphilic compounds include surfactants and detergents. The phospholipid amphiphiles are the major structural component of cell membranes. Amphiphiles are the basis for a number of areas of research in chemistry and biochemistry, notably that of lipid polymorphism. Organic compounds containing hydrophilic groups at both ends of the molecule are called bolaamphiphilic. The micelles they form in the aggregate are prolate. Structure The lipophilic group is typically a large hydrocarbon moiety, such as a long chain of the form CH3(CH2)n, with n > 4. The hydrophilic group falls into one of the following categories: # charged groups #* anionic. Examples, with the lipophilic part of the molecule represented by ''R'', are: #** carboxylates: RCO2 ...

Household Chemicals
Household chemicals are non-food chemicals that are commonly found and used in and around the average household. They are a type of consumer goods, designed particularly to assist cleaning, house and yard maintenance, cooking, pest control and general hygiene purposes, often stored in the kitchen or garage. Food additives generally do not fall under this category, unless they have a use other than for human consumption. Additives in general (e.g. stabilizers and coloring found in washing powder and dishwasher detergents) make the classification of household chemicals more complex, especially in terms of health - some of these chemicals are irritants or potent allergens - and ecological effects. Together with non-compostable household waste, the chemicals found in private household commodities pose a serious ecological problem. In addition to having slightly adverse up to seriously toxic effects when swallowed, chemical agents around may contain flammable or corrosive subs ...

Cosmetics Chemicals
Cosmetics are substances that are intended for application to the body for cleansing, beautifying, promoting attractiveness, or altering appearance. They are mixtures of chemical compounds derived from either natural sources or created synthetically. Cosmetics have various purposes, including personal and skin care. They can also be used to conceal blemishes and enhance natural features (such as the eyebrows and eyelashes). Makeup can also add colour to a person's face, enhance a person's features or change the appearance of the face entirely to resemble a different person, creature, or object. People have used cosmetics for thousands of years for skin care and appearance enhancement. Visible cosmetics for both women and men have gone in and out of fashion over the centuries. Some early forms of cosmetics contained harmful ingredients such as lead that caused serious health problems and sometimes resulted in death. Modern commercial cosmetics are generally tested for safe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Arm & Hammer
Arm & Hammer is a brand of baking soda-based consumer products marketed by Church & Dwight, a major American manufacturer of household products. The logo of the brand depicts the ancient symbol of a muscular arm holding a hammer inside a red circle with the brand name and slogan. Originally associated solely with baking soda and washing soda, the company began to expand the brand to other products in the 1970s by using baking soda as a deodorizing ingredient. The new products included toothpaste, laundry detergent, underarm deodorant, and cat litter. History Name and logo The original Arm and hammer logo usage dates back to the 1860s. James A. Church, son of Dr. Austin Church, ran a spice business known as Vulcan Spice Mills. According to the company, the Arm and Hammer logo represents Vulcan, the Roman god of fire and metalworking. It is often claimed that the brand name originated with tycoon Armand Hammer; however, the Arm & Hammer brand was in use 31 years before ...

Toothpaste
Toothpaste is a paste or gel dentifrice that is used with a toothbrush to clean and maintain the aesthetics of Human tooth, teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis).American Dental Association Description of Toothpaste Due to variations in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be poisonous. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. History Early toothpastes Since 5000 BCE, the Egyptians made a tooth powder, which cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colgate (toothpaste)
Colgate is an American multinational brand principally used for oral hygiene products such as toothpastes, toothbrushes, mouthwashes and dental floss. Manufactured by Colgate-Palmolive, Colgate's oral hygiene products were first sold by the company in 1873, sixteen years after the death of the founder, William Colgate. The company originally sold soap. History Colgate toothpaste was sold in glass jars since 1873. Tubes, as pioneered by Kalodont, Johnson & Johnson (Zonweiss) and Sheffield, were introduced in 1896. Colgate became popular in the 1950s, with the slogan "It Cleans Your Breath While It Cleans Your Teeth", written by copywriter Alicia Tobin. In 2007, the Advertising Standards Authority in the UK told Colgate that it could no longer make the claim that four out of five dentists recommended Colgate. The investigation showed that the study had telephone surveyed dentists to list the toothpaste they recommended, and their competitors were recommended at similar rat ...

Small Molecules
In molecular biology and pharmacology, a small molecule or micromolecule is a low molecular weight (≤ 1000 daltons) organic compound that may regulate a biological process, with a size on the order of 1 nm. Many drugs are small molecules; the terms are equivalent in the literature. Larger structures such as nucleic acids and proteins, and many polysaccharides are not small molecules, although their constituent monomers (ribo- or deoxyribonucleotides, amino acids, and monosaccharides, respectively) are often considered small molecules. Small molecules may be used as research tools to probe biological function as well as leads in the development of new therapeutic agents. Some can inhibit a specific function of a protein or disrupt protein–protein interactions. Pharmacology usually restricts the term "small molecule" to molecules that bind specific biological macromolecules and act as an effector, altering the activity or function of the target. Small molecules can have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
