Functions of Surfactants
The process of development of new surfactants is based on our expertise in colloid science and organic synthesis.
- Foaming / foam extinguishing
- Biological activity
- Surface treatment
- Emulsion polymerization
Solubilization technology uses surfactants to allow insoluble or poorly soluble substances to be incorporated into liquids sustainably.
Examples of solubilized preparations include:
- Cosmetics - Fragrances, vitamin derivatives, and oils in aqueous lotions and toners
- Pharmaceutical - Active ingredients and other poorly soluble compnents in topical drugs, ointments, injection liquids, nutraceutical drinks, and mouthwashes
- Food - Flavors, vitamins, and other active components in drinks
- Home care - Fragrances into air-care and household products
- Other - Monomers in inks; oils in anti-rust products
Emulsions refer to stable mixtures of two or more immiscible liquids where one liquid (the "dispersed" phase) is dispersed into the other (the "continuous" phase).
Example preparations include:
- Cosmetics/Pharmaceutical - Water-in-oil (W/O), oil-in-water (O/W), multiple preparations (W/O/W, O/W/O), microemulsions, and liposomes for topical creams and lotions
- Foods - Mayonnaise, margarine, sauces, dairy products
- Home - Cleansing waxes, polishers
- Other - Emulsion-type inks and paints
Dispersions refers to general systems in which a single type ofparticle - solid, liquid, or gas - is mixed evenly into a "continuous" phase of another particle.
- Cosmetics - Solid components (UV filters, pigments, powders) in makeup products, such as lipsticks, foundations, and mascaras, and skin care products (sunscreens)
- Pharmaceutical - Active ingredients and powders in medical drugs
- Food - Chocolate
- Other - Pigments and colorants in inks and paints; cement liquefying blends
Foaming / foam extinguishing
Foaming systems consist of gas bubbles trapped in a liquid or solid, while foam extinguishers refer to substances and blends that destabilize and reduce foam.
- Cosmetics - Shampoos, body and face washes, hair coloring products
- Oral care - Toothpastes and mouthwashes
- Home/Industrial - Detergents and cleansing products for use at home, including for washing food and dishes, or on industrial equipment
- Foods - Confectioneries, including whipped creams, mousses, sponge cakes
Some surfactants are said to show biological activity when theyinfluence the condition of the human organism, for example through changes in the structure of cell membrane and in the production of lipids and proteins. Often, natural surfactants resemble substances found in the human body and are considered safer than synthetic surfactants. Examples of surfactants with biological activity include:
- Natural surfactants - Lecithin derivatives and phytosterols for safe, low-irritation skin care
Lubrication technology reduces friction and thus the wear of surfaces by locating lubricating oils and surfactants between surfaces moving in close proximity.
Examples of lubrication include:
- Cosmetics - Smooth, easy-to-apply hair care and skin care products
- Industrial - Various lubrication preparations
- Other - Easy-to-apply inks and paints
Surface treatment refers to various industrial processes which alter the surface properties of a material, including repellency/adhesion to water and other substances, corrosion resistance, wear resistance, hardness, friction, and general appearance.
- Cosmetics - Treated powders with hydrophilic/lipophilic properties used in skin care and makeup
- Industrial - Various industrial surface preparations
- Other - Polishes and waxes for home care and automobile care; Anti-corrosion preparations
Emulsion polymerization involves the polymerization of water, monomer, and surfactant.
This technology is used in various industries to manufacture synthetic polymers such as rubbers and latex.
Detergents are surfactants or mixtures of surfactants which remove dirt, grease, proteins, and other types of contamination from various surfaces. They are commonly used as cleaning products on anything from clothing fabrics to household appliances and industrial equipment.
