Dirt attraction

Phospholipid EFA adds shine and a silky texture to the animal s coat or mane. The Monaquat TG provides body building conditioning and detangling while leaving a soft smooth feel. Monaquat ISIES is an effective long lasting antistat that controls dirt attraction. [Pg.171]

Stops static and removes electrostatic charges and related dust and dirt attraction on all types of hard surfaced plastics such as acrylics, polystyrenes, PVC, styrenes, vinyl, thermoplastics, and thermosets. Stops static on films and paper. Assists solar heat-transfer. [Pg.245]

Very fine particles such as smokes can be caught by electrostatic precipitation. A high voltage is applied to plates or wires within the filter bank, to impart a static charge to dirt particles. These will then be attracted to earthed plates, and adhere to them. Impurities are generally cleaned off the plates by removing the stack and washing. [Pg.294]

Sheet vinyl is best installed by professionals, whereas tiles can be laid by amateurs if instructions are followed carefully. Sheet flooring is usually considered more attractive and easier to maintain. It has few seams to open up in time and become dirt catchers or entrance points for moisture. In some materials, seams can be welded by heat, thus forming a permanent seal. Others will in time require additional sealer. Tiles, on the other hand, can be laid with less waste and also have the advantage of being replaceable if damaged. Whichever type is chosen, a supply of extra tiles or a few scraps of sheet flooring should be kept for possible future repairs. [Pg.65]

The active ingredients in a shampoo play three fundamental roles. Some allow water to wash away the substances that make hair dirty. Others adhere to hair to impart a desirable feel and texture. The rest are emulsifiers that keep the mixture from separating into its components. To accomplish these effects, ingredients combine two types of interactions a strong attraction to water (hydrophilic) and an aversion to water (hydrophobic). It may seem that these properties are incompatible, but shampoos contain molecules that are designed to be simultaneously hydrophilic and hydrophobic. One example is sodium lauryl sulfate, our inset molecule. The ionic head of the molecule is hydrophilic, so it interacts attractively with water. The hydrocarbon tail is hydrophobic, so it interacts attractively with grease and dirt. Molecules of the shampoo associate with hydrophobic dirt particles to form hydrophilic clumps that dissolve in water and wash away. [Pg.828]

Sodium carbonate is an alkali, a strongly basic compound that has a pH of 9 or more in solution. Boiling an alkali with fat makes soap. Chemically, soap contains a long chain of hydrocarbons that repels water but has an affinity for other fatty substances. When treated with alkali, the ends of the fatty chains are modified so that they are attracted to water. A molecule with one end that attracts fatty substances and another end that likes to dissolve in water is ideal for coating dirt particles and floating them away in water. Soap can be made from any kind of fat, whether from kitchen scraps or whale, olive, or palm oil. [Pg.5]

Dirt is attracted to and held on the skin and clothing mostly by fats and oils that are insoluble in water. Soap, an artificial, human-made (synthetic) substance, cleanses by making fats and oils dispersible in water soap acts as an emulsifier, a substance that disperses solids into liquids in which they are usually immiscible. When used as a body cleanser, for example, soap combines with oils and fats together with dirt particles on the skin, emulsifying and dispersing them in water in such a way that they can be disposed of with the water. [Pg.343]

The containers must first be unscrambled. Watch out for induced dirt from friction, fracture of fragile containers, and static electricity from dry conditions and movement of plastics, which can attract small dust particles from the surrounding air. Most containers used for sterile filling (ampules, vials, bottles, and collapsible tubes) will be brought to the fdling line in precleaned and sterilized trays, so unscrambling might not be necessary. There are also certain types of outer cleaned bottles that are supplied in clean layers, with the outer plastic protection removed online. [Pg.671]

Because like dissolves like, the nonpolar end (hydrophobic or water-hating part) of the soap molecule can dissolve the greasy dirt, and the polar or ionic end (hydrophilic or water-loving part) of the molecule is attracted to water molecules. Therefore, the dirt from the surface being cleaned will be pulled away and suspended in water. Thus soap acts as an emulsifying agent, a substance used to disperse one liquid (oil molecules) in the form of finely suspended particles or droplets in another liquid (water molecules). [Pg.405]

The trouble with glass is that it seems to attract dirt, and as we know from our own homes it has to be cleaned, especially in urban environments where city dust and vehicle fumes can settle as a thin film. [Pg.139]

Soap is the grand diplomat of intermolecular forces. Soap gets along with and experiences attractions to both water and oil, which is the basis for its efficacy as a cleaning agent. Soap combines with grease, oil, and dirt, and then with water, which allows the dirt to be washed away with the water. [Pg.132]

Do not grow nicotiana in dusty areas the sticky, fuzzy leaves attract and hold dirt. Also, do not plant near tomatoes. Nicotianas may attract insect pests and diseases that seldom seriously bother this hardy plant, but will quickly move on to any nearby tomatoes. [Pg.155]
