Compatibility of ZELIQUID LP 2:
ZELIQUID LP 2 is compatible with other anionic and nonionic surfactants and resistant to water hardness.
In mineral acid solutions at elevated temperature ZELIQUID LP 2 like all ether sulphates tends to hydrolyse.
Production and Synthesis of ZELIQUID LP 2:
ZELIQUID LP 2 is synthesized as the ammonium salt of lauryl poly(ethylene glycol) ether sulfate, specifically ethoxylated with approximately three moles of ethylene oxide.
The industrial production mirrors common processes used for ether sulfate surfactants: ZELIQUID LP 2 begins with ethoxylation of lauryl (dodecyl) alcohol—typically derived from natural oils like palm kernel or coconut—to form lauryl ethoxylate, which is then sulfated using agents such as chlorosulfonic acid or sulfur trioxide.
The intermediate is subsequently neutralized with ammonia to produce the final ammonium lauryl ether sulfate.
Formulated into a clear, water-soluble liquid—often around 50% active surfactant, with the remainder comprising solvents such as 2‑butoxyethanol and water—ZELIQUID LP 2 provides a balanced, pumpable formulation with a neutral skin-compatible pH (approx. 7–8).
The finished product is carefully refined and tested to ensure compatibility with both anionic and nonionic surfactants, resistance to water hardness, and reliable physical properties like solubility, stability, and viscosity—critical for its dual use in personal care cosmetics and construction applications such as air entrainment in gypsum board manufacturing.
History of ZELIQUID LP 2:
Surfactants trace their origins back over four millennia, with soap-like substances first used in ancient Babylon around 2800 B.C., composed of water, alkali, and cassia oil, followed by early mentions of soap in Roman-era writings by Galen around 200 A.D.
The modern era of synthetic surfactants began in the early 20th century when sulfation of fatty alcohols—pioneered in the late 1920s—paved the way for more effective detergents that outperformed soap in hard water; companies like Henkel and Procter & Gamble began commercializing products like SLES-based detergents in the early 1930s.
Since the 1950s, sodium lauryl ether sulfate (SLES) and related ether sulfates have become ubiquitous in personal care and cleaning products due to their versatility and mild cleansing properties.
Within this evolving landscape, ZELIQUID LP 2—an ammonium lauryl poly(ethylene glycol) ether sulfate—is positioned as a more specialized, newer-generation surfactant.
ZELIQUID LP 2 integrates seamlessly into both personal care applications, thanks to its skin-friendly, stable formulation, and industrial uses, such as enhancing gypsum plaster through air entrainment technology.
Thus, ZELIQUID LP 2 exemplifies how modern surfactant chemistry continues to evolve, building on nearly a century of innovation to meet increasingly nuanced functional and environmental demands.

Air Entrainers:
Air entrainment is the intentional creation of small air pockets in concrete by the addition of an air entraining agent to the mix.
The primary purpose of air entrainment is to increase the durability of the hardened concrete, especially in climates subject to freeze-thaw as the air pockets relieve internal pressure on the concrete by providing tiny chambers for freezing water to expand into.
Additionally, workability of the concrete is increased.
Based on our experience in surfactant chemistry, we offer a range of air entraining agents under the brand names Hostapur and, Genapol, and ZELIQUID.
Our Hostapur OSB is used as an air entraining agent for mortars, plasters and grouts based on cement, gypsum or lime.
It is rapidly soluble, enables faster wetting of solid particles in the dry admixture and the build-up of micro foam in a short time.
The performance of this air entrainer is superior to traditional sodium lauryl sulfates, as ZELIQUID LP 2 is not sensitive to calcium salts, non-hygroscopic and twice as efficient in producing controllable, strong and stable micro foam.
Solid Air Entraining Agents:
Genapol LSS Powder:
