Amphoteric Surfactants

amphoteric surfactants

Amphoteric Surfactants are versatile molecules that exhibit cationic behavior at acidic pH, anionic behavior at alkaline pH, and nonionic behavior within their isoelectric or zwitterion range. Amphoterics are generally used in combination with primary surfactants such as sulfates or nonionic surfactants. Amphoteric surfactants are commonly used in a variety of formulations and markets including HI&I, oilfield, and personal care.

Betaines are molecules possessing cationic behavior in the lower pH range and are zwitterions throughout the rest of the pH range maintaining both a positive and negative charge. Betaines exhibit outstanding stability across a wide pH range and are excellent foam boosters and viscosity builders when used in combination with primary surfactants. Betaines exhibit excellent foam stability in hard water and are also used in wide variety of markets.

 

DeTERIC Series – Amphoteric Surfactants

DeTERIC LP sodium lauriminodipropionate, CAS # 14960-06-6, is a readily biodegradable, high foaming amphoteric surfactant offering detergency, wetting, hydrotroping and emulsifying properties. It’s salt-free and brine stable and can be used across a wide pH range including in strong acid and highly alkaline systems.It’s also an effective acid corrosion inhibitor exhibiting excellent corrosion protection for a variety of metals, including aluminum, in hydrochloric, sulfuric, and phosphoric acids. It’s approved for use as an inert in non-food pesticides, and due to its mildness can also be used in personal care applications.¬†INCI name: Sodium Lauriminodipropionate.

DeTERIC CP-Na-38 is similar to DeTERIC LP with higher actives, higher foaming properties, and increased alkaline and acid stability. Readily biodegradable.

DeTERIC ODP-LF sodium octyliminodipropionate, CAS #94441-92-6 is a very low foaming amphoteric with excellent alkaline & acid stability. Suggested for use as a highly effective hydrotrope in low foaming alkaline or acid cleaners. Exhibits corrosion inhibition properties. Approved for use as inert in non-food pesticide formulations. Zero VOCs (ASTM E-1868-10/SCAQMD Rule 1144).

DeTERIC LF-Na-50 is a 50% active, partially neutralized, short chain propionate with good wetting and hydrotroping properties. Recommended for use in acid or alkaline formulations.

DeTERIC CSP-50 is a low foam, phosphated amphoteric suggested for use in highly alkaline systems. It has the unique ability to reduce the surface tension of 50% active caustic and also maintains its very low color in this highly challenging environment.

 

DeTAINE PB- Cetyl Betaine

DeTAINE PB palmitic/cetyl betaine, is a colorless and odorless, alcohol-free betaine producing dense foam and exhibiting unique viscosity building properties in combination with anionics such as SLS and SLES. It’s an excellent choice for high foaming acid or alkaline cleaners as well as for personal care products. ¬†Approved for use as an inert in non-food pesticides. INCI name: Cetyl Betaine
