What are the advantages and disadvantages of defoamers for cosmetic raw materials?

1.Polysiloxane dispersion is more difficult: polysiloxane is insoluble in water, which hinders its dispersion in the water system, and must add a dispersant, and if the dispersant is added, the emulsion will be stabilized, and the defoaming effect will become worse, and the emulsifier must be used less to make the defoaming effect good and the emulsion stable.

2.Silicones are oil-soluble, reducing their defoaming effect in oil systems.

Advantages of defoamers for cosmetic raw materials:

1.Wide range of applications: Due to the special chemical structure of silicone oil, it is not miscible with water or substances containing polar groups, nor with hydrocarbons or organic substances containing hydrocarbon groups.

Due to the insolubility of silicone oil to various substances, it has a wide range of applications, which can be used for both defoaming in water system and oil system.

2.Small surface tension: The surface capacity of silicone oil is generally 20-21 dynes, which is smaller than that of water (72 dynes) and general foaming liquid, and the defoaming effect is good.

3.Good thermal stability: taking the commonly used dimethicone oil as an example, it can withstand 150 for a long time and more than 300 for a short time, and its Si-O bond does not decompose. This ensures that silicone defoamers can be used over a wide range of temperatures.

4.Good chemical stability: Since the Si-O bond is relatively stable, the chemical stability of silicone oil is very high, and it is difficult to react with other substances. Therefore, silicone defoamers are allowed to be used in systems containing acids, alkalis and salts as long as they are properly formulated.

5.Physiological inert: Silicone oil has been shown to be non-toxic to humans and animals, and its semi-lethal dose is greater than 34 g kg. Therefore, silicone defoamers (in combination with suitable non-toxic emulsifiers, etc.) can be safely used in food, medical, pharmaceutical and cosmetics industries.

6.Strong defoaming power: Silicone defoamers can not only effectively break the foam that has been generated, but also significantly inhibit the foam and prevent the formation of foam.

It is used in very small quantities and only needs to be added as one millionth by weight (1 ppm) of foaming media to produce a defoaming effect. It is commonly used in the range of 1 to 100 ppm. It is not only low cost, but also does not pollute the substances to be defoamed.

The defoamer for cosmetic raw materials is refined by a variety of special polyethers through composite technology, which has good defoaming and high shear resistance functions, and does not affect the appearance, does not bleach, does not break the emulsion, does not float, and will not produce residual hanging on the wall. There is no adverse effect on post-processing.

Strong defoaming and foaming inhibition power, low dosage, does not affect the basic properties of the foaming system.

Good heat resistance, chemical stability, non-corrosive, non-toxic, non-defective, non-flammable, non-explosive.

It should be sealed well, and it should be moisture-proof, strong-alkali, acid-proof and rain-proof and other impurities.

There are many types of defoamers, and their characteristics are also different, each with its own autumn color. From ordinary hydrocarbon oils, polysiloxane oils, fatty acids and their salts, to polyoxyethylene series, etc., the defoamer is often divided into several categories, the common ones are classified according to the chemical composition of the defoamer, and the classification is classified according to the papermaking production process.

According to the chemical composition of the defoamer, it can be divided into:: Advanced alcohols, fatty acids and their salts, phosphate esters, hydrocarbon oils, polyethers, silicone polymers, amides, etc.

Classified by papermaking processAccording to the papermaking process, the defoamer can be divided into three categories: pulping defoamer, papermaking defoamer, and coating defoamer.

a.Pulping defoamer.

This type of defoamer refers to the chemicals used to eliminate foam in the pulping process. For example, in the unbleached alkali method and sulfate pulping, it contains a large amount of soluble organic matter; Waste paper pulp also contains saponifications after deinking.

During the washing, screening and bleaching process, a large amount of foam often accumulates, and when the black liquor is evaporated and concentrated, it will also produce serious foam, which will affect the washing and concentration effect. Chemicals composed of hydrocarbon oil solvents and lipophilic surfactants are pulping defoamers, which have alkali resistance and high temperature resistance, and can reduce or eliminate foam, improve washing, screening and concentration effects, save water, and improve the dryness of pulp after dehydration.

b.Papermaking defoamer.

Refers to chemicals used to eliminate foam on paper machines. In the process of papermaking, due to unreasonable sizing and washing of poor pulp, the use of alkaline fillers in acidic systems, and excessive or other inappropriate additives in the pulp, foam accumulates in wet end systems such as paper machine grit tanks, high boxes, net front boxes, and white puddles.

Paper containing foam may form a cavity on the surface of the paper when making paper, so it is necessary to add a defoamer. The defoamer used in paper machines is usually used as an emulsion-type defoamer composed of silicone oil, fatty amide calcium (sodium) soap or propylene oxide derivatives, and is also used as a degassing agent composed of non-ionic surfactant. These defoamers can reduce needle holes, improve smoothness, enhance water filtration and help improve the wet strength of the sheet.

c.Apply defoamer.

Refers to the chemicals used to eliminate foam in the coating process of paper. There are two kinds of antifoam and defoaming, and the one used to prevent the absorption of air and foam during the coating process is the antifoam; Defoamers are used to eliminate foam that has been generated in the coating system.

These defoamers require that the coated paper has no "fish eyes" after drying, and does not affect the brightness and printing performance of the coating, commonly used such as: organophosphates, such as tributyl phosphate, tripropyl phosphate, etc.; There are also defoamers made of fatty amides and polyoxyvinyl esters, alcohols, ethers and other surfactants. For more information about defoamers, please consult the official website of Cist.

There are many types of defoamers, which are mainly divided into three categories: mineral oils, silicones, and polyethers.

Features: (1) The surface tension is lower than that of foam medium, 2) Insoluble in foam medium;

3) It does not react with the foam medium and does not decompose.

4) Good defoaming and antifoaming ability;

5) Stable storage and low cost.

Defoamers depend on whether you want to divide them by ingredient or by industry. Generally, silica defoamers are widely used, and they have been developed for a long time. For example, silicone defoamers, polyether modified silicon defoamers, etc., as well as various compound defoamers, alkane defoamers, and various different ingredients correspond to different industries.

There are also imported and domestic defoamers. The amount of imported additives is small, but the defoaming is fast, and it is more expensive. The amount of domestic additives is large, and the defoaming effect is not so good, but it is cheap.

It depends on what manufacturer you are aiming for, if you pursue quality, it is recommended that you choose imported, after all, it is decades earlier than the development of domestic production. It is recommended that you refer to Dachuan defoamer, the types in it are relatively detailed, I hope it will be helpful to you, hopefully.

In daily life and production, foam brings people colorful, fantasy and fun, but also increases people's troubles. In life and production, many operations or processes often become serious problems due to the production of large amounts of foam. The textile industry from spinning, spinning, weaving, printing and dyeing to the finished product in the processing process, all kinds of auxiliary chemicals are used, which give textiles a variety of excellent application properties, improve the quality of textiles, improve processing effects, improve production efficiency, simplify the production process, reduce production costs.

This auxiliary chemical is commonly known as textile dyeing and finishing auxiliaries. Due to the large use of textile dyeing and finishing auxiliaries, a large amount of foam is produced in the wet processing process of textile dyeing and finishing, which makes the production operation inconvenient, the production capacity is reduced, the product quality is reduced, and the normal operation is difficult. Therefore, the textile dyeing and finishing industry should eliminate harmful foam.

1) Products based on natural products: animal and vegetable oils, mineral oils and compounds, etc.;

2) Polyether type: block copolymer with polyoxyethylene polyoxypropylene, modified polyether, etc.;

3) Silicone defoamers with polysiloxane as the main raw material include: pure silicone oil, silicone oil solution, silicone paste, silicone oil emulsion, powder, and block.

According to the dosage form, the defoamer can be divided into: solution, emulsion, powder, paste, and block. Defoamers are divided into food, pharmaceutical, and fermentation according to their uses; papermaking, printing and dyeing auxiliaries; oil extraction, storage and transportation, refining, lubricating oil; chemical production; Metal cutting fluids, chemical cleaning, water treatment, and more.

According to the focus of the performance, defoamers can be divided into: defoamers, antifoam agents and deaerators.

Silicon-based and non-silicon-based defoamers are used in different processes in the textile printing and dyeing industry, and the actual use performance has its own advantages and disadvantages. Silicon-based defoamer has the advantages of strong defoaming performance, long-lasting foam inhibition, low dosage, stable chemical properties, high temperature resistance, non-volatile and non-toxic, etc., and is an important development direction of textile dyeing and finishing auxiliaries. In the dyeing and finishing of textile fabrics, defoamer water emulsions containing polysiloxane 1% and 2o% are usually used.

Defoamers have industrial uses and other food uses, and are mainly used in industry to eliminate foaming problems such as coatings, inks, adhesives, latex gloves, metalworking fluids, cleaning, and dampening solutions.
