What is a Wetting Agent

 A wetting agent is a substance that reduces the surface tension of water, it spreads water on the surface and increases the ability of liquid dispersion. Reducing the surface tension will reduce the energy required to distribute the droplets onto the film, thereby weakening the cohesion of the liquid and enhancing its adhesion. An example of how wetting agents work is the formation of micelles. The micelle consists of a hydrophilic head, which forms an outer layer around the lipophilic tail. When it is in water, the tail of the micelle can surround the oil drop and draw its head into the water.

 

Dishwashing soap is a good example of a wetting agent. For all food oils and the cohesion on the board, it is difficult for water to disperse and clean the board. Soap dissolves all these unwanted particles, showing us a clean surface. Soap can also reduce the surface tension of water and make it evenly distributed on the whole surface.

 

There are four types of wetting agents: anionic wetting agent, cationic wetting agent, amphoteric and non-ionic wetting agent.

 

1. When mixed with water, anionic, cationic and amphoteric wetting agents will ionize.

 

2. Anionic wetting agent has negative charge, while cationic wetting agent has positive charge.

 

3. According to the acidity of the solution, amphoteric wetting agents can act as anions or cations.

 

4. Nonionic wetting agents will not ionize in water. The possible advantage of using a non-ionic wetting agent is that it does not react with other ions in the water, which may lead to the formation of precipitates.

 

How to identify if a liquid contains a wetting agent

 

One way to identify if a liquid contains a wetting agent is to spread the liquid over a greased surface. If the liquid does not contain a wetting agent, its cohesion will overwhelm the adhesion, resulting in the formation of droplets on the surface. If the liquid does contain a wetting agent, the grease will be dissolved and the surface tension of the liquid will be reduced, resulting in the adhesion force exceeding the cohesion force, which will cause the liquid to spread evenly along the surface.

Difference Between Sodium Laureth Sulfate And Sodium Lauryl Sulfate

Sodium laureth ether sulfate  (SLS) and sodium lauryl ether sulfate (SLES) are surfactants that play a role in foaming products. It is widely believed that the foam produced by a product is its performance. The composition of SLS and SLES reduces the surface tension of water. They can also be used as dispersants to properly mix spices and body spray. SLS and SLES can also be used in a variety of personal care products such as soap, shampoo, shower gel, toothpaste and other foaming products. SLS and SLES are also added to moisturizing lotions and sunscreens because of these properties. The difference between SLS and SLES is in the manufacturing process. SLS undergo a process called ethoxylation. And then you get SLES. Why do we have this ethoxylation process? Because SLS has some mild irritation on the skin, such as dry. The manufactured SLES are more gentle and do not irritate the skin. Many manufacturers do not use SLS because it is irritating. SLES should be softer o...

Polyether Polyol Vs Polyester Polyol

Polye s ter Polyol Vs Polyet h er Polyol   Polyester polyol , which are organic substances, are usually formed by condensation (or transesterification) of an organic dicarboxylic acid (anhydride or ester) with a polyol (including a diol) or by polymerization of a lactone with a polyol. The dibasic acid is phthalic acid or phthalic anhydride or an ester thereof, adipic acid, halogenated phthalic acid or the like. The polyether alcohol is ethylene glycol, propylene glycol, diethylene glycol, trimethylolpropane, pentaerythritol or the like. Different types of polyester polyols have different properties due to different types or different preparation processes. Several indicators that are important for polyester polyols are hydroxyl number, acid value, moisture, viscosity, molecular weight, density, and color. Characteristics and uses of polyester polyols: Polyester-based polyurethane contains a large number of polar groups such as ester groups and amino groups in the molecule, an...
