South Africa surfactant market analysis

Although affected by the financial crisis, the stagnation of the development of the surfactant market in South Africa for two years. However, with the 2010 South Africa’s economic recovery, consumer household products, personal care products, demand is increasing, thus promoting the South African market, the surfactant to the rapid development.
Market will reach $ 235 million
In South Africa, surfactants are generally anionic, nonionic, cationic and amphoteric surfactants  four types, mainly for the production of household detergent or cleaning supplies, industrial special cleaning supplies, personal care supplies.
Anionic surfactants decontamination ability, commonly used for the production of washing and decontamination products, such as detergent, washing liquid, etc., can well remove the dirt knitwear, fabric softener residue from the other. Nonionic surface active agents are often used to produce oil scavenger, wherein the ether alcohol is most common. The performance of the amphoteric surfactant mild, mainly for the production of personal care products and household cleaning products. Cationic surfactants are mainly used to produce detergents, fabric softeners, and household or bathroom cleaners.
Research report said the global financial crisis, in 2009 the South African market surfactant compared with 2008 increased by only 0.9 per cent, reaching $ 190 million. The report predicts that from 2011 to 2016, the South African market will be 3.1% of the average growth rate in 2016 is expected to reach $ 235 million. Wherein the anionic surfactant and a nonionic surfactant  to reach a market share of 69% and 20% , ranked first and second , and amphoteric surfactants and cationic surfactants market share is relatively small , respectively, accounted for only 4.0% and 7.0% respectively.
The four factors promoting the development of the market
Report analysis, surface active agent in South Africa has the following four positive factors of market development.
1, the family consumer goods demand. In the past decade, despite the global economic recession, South Africa's economy still grew by 37.8%. As consumer income increases, people are willing to pay higher prices for quality products, so as to greatly promote the personal care products, household detergents and cleaning products demand.
2, the growth of the healthcare industry. The South African government spent heavily to improve residents' health care system in order to boost demand surfactant growth. Hospital infrastructure and health care facilities is the main surfactant in industry professional application field of end users, extend and improve medical service network to become the most important in the application of the surfactant in industry professional driver, the application area accounts for 20% of the total market share.
3, the requirements of manufacturing formula. Need to use a specific production surfactant formula, formed the time tested formula can ensure the performance of the product. And end user is not very sensitive to the price of the product, they will not according to the price fluctuation to change the demand for their product formula or surfactant.
4, limited types of alternative products. Surfactants are important   in consumer products the active ingredient of many properties of the product to reflect mainly through them, so the surface active agent can not be easily replaced. Both worldwide and in the South African market, this is to maintain the growing demand for surfactants key factor.
With the global economic recovery, South Africa surfactant market will keep growing for some time, and this region surfactant demand will continue to promote local manufacturers and distributors of revenue growth.

Demand centres around mature markets

Cat litter is a well-established production the mature markets of Western Europe, North America and Japan. While a large cat population is the ultimate prerequisite for high value sales of cat litter, other factors also impact demand. In countries with high disposable incomes, and where pet food is a well-established concept, demand for cat litter is comparatively strong.
Urbanisation and the concomitant rise in the number of house-cats also drive demand for cat litter in many countries. The top five in value terms – US, Japan, Germany, UK and France – exhibit these characteristics to varying degrees.
The US has by far the largest cat population, which compensates for the fact that the country lags somewhat in terms of urbanisation. Germany on the other hand has a smaller number of cats, but is, next to the UK, a heavily urbanised country (about 89% of households in the UK and Germany live in urban areas). All five markets are characterised by high levels of personal disposable income, ranking among the top twenty countries worldwide.
Product innovation boosts growth in the US
The US which accounts for about 45% of world cat litter sales, witnessed the introduction of superior-quality products such as clumping and silica gel (crystal) litters, which ensured that cat litter continued to achieve strong growth. A offer better absorption and odour control than conventional cat litter.
Clumping litter, the most common format in the US, is easily scoopable and more convenient to use than traditional products. Furthermore it requires more frequent purchasing, contributing to overall sales growth. Clorox recently introduced Scoop Away Plus Crystals, a product which combines clumping and crystal litters into one product. Innovative product development also kept private labels at bay: The share held by private label products was 16% in 2001, considerably lower than the 28% share held by private label in Western Europe.
To US consumers, product functionality has been and continues to be more appealing than low prices. Consequently, added-value products ensured consistently strong year-on-year growth rates in the US: between 1998 and 2002, cat litter sales grew by over 24%, which translated into an actual increase of nearly US$240 million.

Application of surfactants in textile printing and dyeing

A common classification of surfactants is based on the surfactant dissolved in the case of the charge carried by the water , divided into ionic and non-ionic two categories, while ionic surfactants may also be further divided into cationic, anionic, amphoteric three categories , as follows:
A surfactant can significantly lower the surface tension of water to reduce the level within a certain concentration range , the surfactant concentration dependent , when the concentration reaches a certain value , the surface tension of the solution no longer decreased. The surface tension of the solution reaches the desired concentration of the lowest minimum value known as the critical micelle concentration (CMC). Different surfactants with different critical micelle concentration , surfactant concentration used should tare greater than the critical micelle concentration , in order to fully play its role .
Benzene sulfonate (ABS): is the main component of household detergents , acid and hard water , decontamination capabilities are better.
Diffusion agent NN0: multi- staining dye used as a dispersing agent .
(2) the nonionic surfactant:
Penetrant JFC (EA) lift and wetting agent, acid and alkali resistance, to hard water stability, drift in practice for desizing agent, pickling, bleaching, etc.
Peregal0: strong proliferation ability, are used for dyeing and printing. Anionic surfactant and cationic surfactant with bath use, otherwise will be combined with each other and each other. For other cationic auxiliaries and dyes, with bath will also result in dyeing defects. On the other hand, cationic surfactant, generally can't bath with additives, dyes with anion. But in ionic surfactant and nonionic surfactant can be used with bath. By the rapid development of the surfactant, breed is various, should choose best when printing and dyeing processing surface active agent, in order to improve the quality of printing and dyeing products.

The current production technology of hydrazine hydrate

In the 21st century, China’s consumption structure of hydrazine hydrate as: pesticides accounted for 40% of the total share, blowing agents accounted for 30% of water treatment chemicals accounted for 14% accounted for a percentage of the other the thirteen. At present, China is far lower than the foreign hydrazine hydrate production capacity; still can not meet domestic market needs. Therefore, the development of domestic production capacity of hydrazine hydrate and advanced production technology has enormous economic and far-reaching social benefits.
Currently, Japan, South Korea, the United States and France have a larger hydrazine hydrate production capacity, while demand in these countries is limited; it has a strong export capacity. The steady growths in demand of hydrazine hydrate, and gradually become an important global consumer market. Japan and South Korea hydrazine hydrate are mainly exported to China, the United States and France are also optimistic about China's market.
The current production technology of hydrazine hydrate
Now the production of hydrazine hydrate in China is mainly used in the urea method.
The main is a bit of urea is low investment. The operation is simple, device does not need too much, and now the domestic hydrazine hydrate is small-scale production, is one of the most economical production methods. The urea method in our country has been a long time now, almost all companies are using this method, the synthetic yield higher than raschig process. However, due to the use of high raw material prices compared to other methods, it is in mass production, it can not compete with other methods; this method has been largely foreign to be eliminated. Although many domestic enterprises have done a lot of urea method of technological innovation , but taking into account many of the shortcomings of its existence , so many domestic producers is both the production of urea and production of hydrazine hydrate . So now the Chinese urea method is very suitable for the current situation.
About low cost of raw materials Raschig process, in the production of large scale, the total cost than Urea is low, but the Act pollution, high energy consumption and equipment investment, at home and abroad have been very few manufacturers to adopt the methods of production.
Hydrogen peroxide method with Raschig process and ketone of method of economical comparison mainly depends on the relative price of chlorine, sodium hydroxide. The yield can reach 75%, if there is a cheap source of hydrogen peroxide, which is very attractive. But domestic technology is not mature and widely used.
Ketazine method has significant advantages, as ketazine production to avoid the decomposition of hydrazine, yields were close to the theoretical value, and the energy consumption is about Rasi law 1/3. In one method, azine, hydrazine as a ketazine and water to form a low boiling azeotrope is removed from the top, leaving the rest of the water and salt in the tower kettle.
Rasi law hydrazine with water to form high-boiling azeotrope exists in the bottom, a lot of water to be evaporated . And in order to prevent the precipitation of salt tower reactor, but also need to pre- evaporation desalination, so energy consumption. In the energy crisis, prices circumstances, ketazine of energy saving advantage is particularly important. In addition, investments in equipment ketazine France lower than Raschig process. The disadvantage ketazine product to processor and consume acetone. But in general, ketazine method is superior to Raschig process, developed rapidly in recent years.
Now, with the continuous development of the country, for the future of the chemical industry, hydrazine hydrate products  demand will continue to increase, domestic technology in the future will adopt efficient ketazine France. Urea society will eventually come out of the stage.
