Detergents are surfactants (surface-active-agents), which can change the properties of water. They can lower water's suface tension, making it better able to interact with other cleaning agents. They can also add foaming ability. There's no difference between the detergents in your household cleansers and those you use in your bath. It's simply a matter of concentration. Nevertheless, even among detergents, there's a wide variation in both effectiveness and ecological impact. Those based on plants are kinder to the body and environment than those based on petroleum.
Substances which are added to cosmetic products to lower the surface tension as well as to aid the even distribution of the cosmetic product upon application.
Are surface-active agents that are used in all foaming products they are capable of emulsifying oils and holding dirt in a suspension so that they can be rinsed away with water. Surfactants are used in cosmetic preparations to allow lotions and cosmetic liquids to spread out quickly and evenly on the skin. A serious implication with anionic (negatively charged) surfactants is that they may be contaminated with NDELA, a potent carcinogen. The levels at which they are absorbed into the body is much greater than eating nitrate contaminated foods such as bacon, ham etc.
See surface-active agent.
a compound that reduces the surface tension of water
A term to describe substances that provide resiliency and stability to thin films and that markedly lower the surface tension of liquids, thus permitting easier bubble formation. An integral part of the foam manufacturing chemistry.
surface-active agents that reduce surface tension. They help cleaning by loosening, emulsifying, and holding soil in suspension, which can then be more readily rinsed away.
Substances which can reduce liquid surface tension and thus, in a spill remediation scenario, can increase contaminating oil's exposure by enhancing emulsification processes. Bio-surfactants can further contribute to increasing degradation rates by introducing nutrients to aid bacterial activity.
are surface-active compounds which tend to gather on the surface between two chemical phases, such as a water-air interface or a solid-liquid interface. Froth-producing household washing detergents are surfactants.
Active agent which allows oil to mix with water
detergents that act on the hair or skin to emulsify, lift, and remove dirt; usually more than one is present in a product because they need buffering; some examples include ammonium laureth sulfate, ammonium lauryl sulfate, cocoamide MEA, cocoamidopropyi betaine, cocoamphodiacetate, sodium laurel sulfate, sodium lauryl sulfate, sodium laureth sulfate, and sodium lauroyl sarcosinate.
Coined expression for surface active agents which are sometimes called emulsifiers or wetting agents. First appeared in hydrocarbons with the advent of the catalytic cracking process in refining. Caused by the forming of sodium sulfonate and sodium napthanate molecules. Affects liquid/liquid separation by reducing interfacial tension and forming into a slime which blinds off the fibres used in coalescing media.
Surfactants in water sources come from the residues of detergent formulations that are present in treated sewage effluents. They are removed during treatment. 200 µg/l
Contracted from surface-active agents, these are additives which reduce surface tension and thereby improve wetting (wetting agents), help disperse pigments, inhibit foam, or emulsify. Conventionally, they are classified as to their charge: anionic (negative); cationic (positive); nonionic (no charge); or amphoteric (both positive and negative).
A coined word used in industry to include all surface active agents.
Selected surfactants (surface-active materials), or mixtures of surfactants, help in mixing incompatible components of the reaction mixture.
Short for "surface-active-agent". Reduce the surface tension of oils, greases, and other substances, allowing them to be broken up into smaller particles or globules to facilitate cleansing, washing, laundering, etc.
A general term for Surface Active Agents. It is the term used to describe the active cleaning agents in a product. Conventional products use synthetic surfactants often derived from petroleum. Found in: Conventional laundry products, all-purpose cleaners, dish detergent and dish liquids, and other common cleaning products. etrapotassium pyrophosphate/Tetrasodium pyrophosphate Basic phosphates (tetrasodium being the more common of the two) used to reduce water hardness. (See phosphates above) Found in: Conventional laundry detergents, all-purpose cleaners.
Also referred to as detergents, foaming agents or simply as soap, these sodium compounds are important, but foul tasting, ingredients in toothpastes that have to be masked by flavorings and sweeteners. They help to break up and remove food and other stains.
The use of these chemicals allows the formation of an emulsion or intimate mixture of otherwise incompatible substances by modifying the surface properties and influencing the wetting and flowing properties of liquids.
