Dehypon® grades are fatty alcohol alkoxylates. The Dehypon® grades are oleochemical sourced. They are alkoxylated special grades which provide very low foaming properties. The physical form vary from liquid to solid, even granules are available. Dehypon® grades are versatile useable and provide properties such as wetting, soil removal, low foaming and emulsification.

Low foaming surfactants are nonionic surfactants which are modified either by degree of alkoxylation or modified alkyl chain. The modification reduces the foam capacity. All low foaming surfactants are liquid, either 100% active or in a water diluted solution. The solubility of the low foaming surfactants increases in line with their cloud point. Products with a cloud point below room temperature can be made to form clear solutions by adding solubilizers such as alcohols or glycols.

A thermo-separating aqueous two-phase system composed of Dehypon® LS 54, a polymeric surfactant and the waxy maize starch (amylopectin starch), has been used for partitioning of cutinase as a model protein. The phase diagram obtained for this novel polymer-polymer two-phase system shows two-phases with high polymer concentration. The waxy maize starch is enriched in the bottom phase while the copolymer of Ethylene Oxide (EO) and Propylene Oxide (PO) is found in the upper phase. Since, this copolymer (Dehypon® LS 54) is the thermo-reactive, the upper phase can be removed and heated above the copolymer’s cloud-point resulting in the formation of a new two-phase system with a lower water phase containing the target protein and an upper copolymer-rich phase. Present results show that the systems were formed by the waxy maize starch and a copolymer Dehypon® LS 54 may be considered as an interesting alternative to be used in protein purification due to their low cost, in addition, they offer a viable solution to problems of polymer removal and recycling.

Block copolymers provide a broad range of physical properties that make them versatile, low-foam nonionic surfactants made from ethylene oxide and propylene oxide.

Due to the wide range of physical properties, EO/PO block copolymers can be utilized for many different industries and applications. Some of the industries they can be utilized for include paints & coatings, household & industrial cleaning, agricultural chemicals, metalworking fluids, textiles, pulp & paper and personal care.

Block copolymers are multipurpose products which are used in variety of applications, where antifoaming, dispersing and wetting properties plays important role, i.e. in detergents. They can be used in rinse aids, hard surface cleaners, metal cleaners and also as a laundry aids. Due to their unique structure block copolymers have good emulsifying properties. Hence they can be used in agriculture, paints and coatings and other applications.

Characteristic property of EO/PO block copolymers is their defoaming character. They can be used in fermentation processes, textile industry and water treatment where foaming is not require. Summarizing, EO/PO block copolymers can find application in following areas:

• AUTOMATIC DISHWASHING
• DETERGENTS AND RINSE AIDS
• PAINT AND COATINGS
• TEXTILE INDUSTRY
• LAUNDRY DETERGENTS
• WATER TREATMENT
• HARD SURFACE CLEANERS
• FERMENTATION PROCESSES
• AGRICULTURE
• METAL CLEANING
• PULP AND PAPER

Solubility of EO/PO block copolymers in water depends on EO/PO ratio. Solubility of these products increases with increasing ethoxylation degree and decreases with increasing propoxylation degree. Characteristic property of these products is their better solubility in cold water than in hot water.

EO/PO block copolymers are manufactured by reacting ethylene oxide and propylene oxide in combination with an alcohol. EO/PO products have various applications as low-foaming non-ionic surfactants. EO/PO block copolymer have excellent wetting and dispersing properties. EO/PO block co-polymer which are insoluble or have limited solubility in water or ethylene glycol generally have low cloud points (< 50oC).

Block copolymers have a long history as industrial surfactants. The major types of block copolymers, such as those made from ethylene oxide (EO) and propylene oxide (PO) or EO and styrene, are cheap and easy to tailor-make for specific applications. The water-soluble EO-PO block copolymers are stable over a wide pH range and compatible with all other types of surfactants. In addition, they are mild to the skin and hair, a property related to their high molecular weight. In the manufacture of an amphiphilic block copolymer for a specific application there are several degrees of freedom as compared with the synthesis of conventional, low-molecular weight surfactants: (1) the size of both the hydrophilic and the hydrophobic part can be varied at will, (2) the molecular weight can be varied within wide ranges while maintaining constant hydrophilic-lipophilic balance, and (3) the properties and function of a block copolymer at an interface, e.g. oil-water, can be governed by the molecular architecture. As an example, an EO-PO-EO triblock polymer is preferred as steric stabilizer of oil-in-water emulsions whereas water-in-oil emulsions may be better served with a copolymer of PO-EO-PO type. In more recent times slow degradability in the environment of the major type of water-soluble block copolymers, the EO-PO based compounds, has become a major obstacle for both household and industrial use of the products. Improved biodegradability is probably the strongest driving force for the development of new surfactants today and products which do not meet the OECD guideline in rate of degradation into carbon dioxide and water are challenged by alternative products, even if these are more expensive or not as good in terms of technical performance. Environmental considerations have already limited the use of EO-PO block copolymers and are likely to do so even more in the future. Even so, water-soluble block copolymers are still an important surfactant class. The various types of EO-PO based products, constitute the vast majority but ethylene oxide-butylene oxide (EO-BO) copolymers are also on the market. The three smallest alkylene oxide monomers, EO, PO and BO, all give a linear polymer backbone consisting of a repeating C-C-O- segment.

A nonionic surfactant is a type of surfactant that does not carry a charge on its hydrophilic head group and is therefore milder in nature. Due to the mildness associated with nonionic surfactants, they are commonly used throughout the home and personal care markets, as well as the agrochemical industry.

Furthermore, the lack of charge contributes to nonionic’s ability to easily emulsify oils, making them a great player in removing grease and oils from soiled surfaces. Though this class of surfactants is commonly associated with cleaning products around the home or an industrial setting, they are widely used in other areas too. Nonionic surfactants are commonly used in the home, beauty, and personal care surfactants markets for products including shampoos (to aid in emulsification), perfumes (as solubilizing agents), cosmetics (to help disperse pigments in make-up), and to assist in the emulsification of oils for skin care products.

Nonionic surfactants are not limited the home and personal care markets, for instance, nonionic surfactants are used to help farmers within the agricultural surfactants industry, as these compounds are used in pesticide and adjuvant formulations to increase spreading, wetting, sticking, and penetration of the pesticide through the leaf’s surface. The refining and processing of oil and gas in the petroleum industry also utilizes nonionic surfactants. For instance, nonionics are used as a corrosion inhibitor in oil and gas for surfaces that come into contact with the petroleum products, as well as flow-back aids to help improve the flow of hydrocarbons. Due to their surface chemistry, nonionic surfactants are also widely used in coating applications, such as emulsifiers for latex paints and leveling agents for acrylic coatings.

Some common examples of nonionic surfactants are ethoxylated and alkoxylated fatty acids, ethoxylated amines, ethoxylated alcohol, alkyl and nonyl-phenol ethoxylates, ethoxylated sorbitan esters, and castor oil ethoxylate.

When choosing the correct surfactant, it is important to understand how the identity of the water-fearing portion, as well as, the ratio of the water-fearing to the water-loving portion can be tailored to provide better water solubility, wetting, detergency, emulsification, etc. To understand this phenomena, one must first understand the hydrophilic/lipophilic balance (HLB) theory, which is uniquely characteristic to nonionic surfactants.

Ranging in arbitrary units of 1-20, the HLB of a nonionic surfactant can be calculated and used to determine the propensity of a compound to work effectively in a given solution of oil and water. Lower HLB values (< 10) are commonly used for oil-rich solutions while surfactants with higher HLB values (> 10) are typically most efficient in oil-in-water emulsions.

Just as the identity of the hydrophobic portion of the ionic surfactant can be varied depending on the need of the final application, the length of the polyoxyethylene component (i.e. the hydrophilic portion) of the nonionic surfactant also provides this class of compounds with a wide assortment of water solubilities and detergency properties. Increasing the amount of ethylene oxide typically increases its water solubility, as well as increases the hydrophilic/lipophilic balance (HLB) of the compound.

Low Foam surfactants are ideal for low- to no-foam applications. These high performance products provide excellent detergency and wetting properties, caustic and acid stability and superior food and protein soil defoaming ability.

Low Foam surfactants are used as rinse aids, commercial machine dishwashing, food & dairy process cleaners, metal cleaning applications, high-shear immersion baths and metal working fuilds.

Low Foam surfactants are also used in pulp & paper, textile processing, pigment dispersions, and other applications.

Nonionic alkoxylates, with ethylene oxide (EO) and propylene oxide (PO) content, can provide excellent rinsing and spray cleaning performance for several high agitation and mechanical cleaning applications.

Examples include: rinse aids for automated detergent applications, dairy and food cleaners, pulp and paper processing applications, textile chemistries, and more.

Moreover, alkoxylates that are based on linear alcohols exhibit very low foam profiles and can be combined with other low foaming components, such as biodegradable hydrotropes, to formulate safe and economical cleaners.

EO/PO block copolymers are known for excellent wetting and dispersing properties.

Low foaming recommendations within this category can serve as highly effective emulsifiers for several industrial and institutional cleaning applications.

Foam is caused by agitation at the air-surface interface.

As such, cleaning actions with high agitation, high shear mixing or mechanical spraying often require appropriate foam control surfactant chemistry.

Selecting a surfactant or combination of surfactants for foam control begins with analyzing foam measurements.

Foam measurements are provided by surfactant producers in their technical product literature. For reliable foam measurements, the data sets should be based on well-recognized foam testing standards.
