Agnique PG 9116 UP has a C9–C11 alkyl chain length range that is longer than the C8–C10 range of Agnique PG 8105-G and PG 8107-G, resulting in a higher lipophilicity, stronger hydrotropic and coupling activity, very low cloud point, and different wetting and compatibilizing profile that makes it particularly effective as a superior adjuvant and glyphosate potentiator in concentrated agrochemical formulations.
Agnique PG 9116 UP is produced by the acid-catalyzed Fischer glycosylation of glucose with a C9–C11 fatty alcohol mixture, yielding a complex mixture of C9 and C11 alkyl mono-, di-, and oligoglucosides with an average degree of polymerization of approximately 1.6, corresponding to an average of 1.6 glucose units per alkyl chain.

Agnique PG 9116 UP is generally recognized as safe (GRAS) by the US FDA for use in cleaning of fruits, vegetables, meat, and poultry products, confirming the excellent food-contact safety profile of C9–C11 alkyl polyglucosides at the purity level designated by the UP suffix.
Agnique PG 9116 UP is permitted for use as an inert ingredient in non-food pesticide products by the US EPA, consistent with the regulatory status of C9–C11 alkyl polyglucosides as low-toxicity, environmentally acceptable formulation components in registered crop protection products.

Agnique PG 9116 UP offers wide electrolytic, temperature, and pH stability, great hydrotropic and coupling properties, and a very low cloud point, distinguishing it from the C8–C10 APG grades (Agnique PG 8105-G, PG 8107-G) which have a higher cloud point and somewhat different compatibilizing performance profile.
Agnique PG 9116 UP is free from VOC, APEO, ethylene oxide residues, and preservatives, and contains over 95% bio-based carbon, supporting sustainable formulation objectives in the agrochemical, personal care, and institutional cleaning industries.

Uses of Agnique PG 9116 UP:
Agnique PG 9116 UP is used as a superior adjuvant and glyphosate potentiator in herbicide spray formulations and tank-mix applications, where the C9–C11 alkyl chain length and DP 1.6 structure provide enhanced compatibilizing performance between glyphosate active ingredient, water, and co-surfactant components compared to C8–C10 APG grades.
Agnique PG 9116 UP is used as a wetting agent, compatibilizer, and hydrotrope in capsule suspension (CS), microemulsion (ME), soluble liquid (SL), suspension concentrate (SC), and suspo-emulsion (SE) agrochemical formulations, providing improved phase stability, wetting of target surfaces, and compatibility between oil and water phases.

Agnique PG 9116 UP is used as an emulsifier and co-emulsifier in oil-in-water agrochemical emulsion formulations, contributing to fine emulsion drop formation, stability against coalescence, and spreading on hydrophobic plant leaf cuticles.
Agnique PG 9116 UP is used as a strong compatibilizer in complex multi-component agrochemical formulations including tank mixes combining herbicides, fungicides, insecticides, and foliar nutrients, helping to maintain solution or suspension stability and preventing antagonistic phase separation between incompatible components.

Agnique PG 9116 UP is used in biological pesticide (biopesticide) formulations as a mild, low-phytotoxicity, GRAS-status surfactant suitable for stabilizing microbial, botanical, or biochemical active ingredients.
Agnique PG 9116 UP is used in home care and institutional cleaning products including hard surface cleaners, bathroom cleaners, kitchen degreasers, floor cleaners, and disinfectant cleaners as a biodegradable, electrolyte-stable wetting and degreasing surfactant.

Agnique PG 9116 UP is used in agricultural fertilizer-compatible formulations where the strong hydrotropic and coupling properties of the C9–C11 APG help maintain homogeneity in high-ionic-strength liquid fertilizer solutions.
Agnique PG 9116 UP is used as a hydrotrope and solubilizer in concentrated liquid formulations for industrial cleaning, paper processing, textile finishing, and metalworking where enhanced solubilization of hydrophobic components in aqueous systems is required.

Benefits or Advantages of Agnique PG 9116 UP:
Agnique PG 9116 UP offers superior hydrotropic and coupling properties compared to C8–C10 APG grades, making it more effective as a compatibilizer for complex agrochemical formulations containing both hydrophilic active ingredients and hydrophobic oil or solvent components.
Agnique PG 9116 UP has a very low cloud point arising from its C9–C11 alkyl chain length and DP 1.6 structure, meaning it remains homogeneously dissolved in formulations across a wider range of temperatures without phase separation.

Agnique PG 9116 UP is readily biodegradable, has very mild skin irritancy and very low acute toxicity, and is designated GRAS by the FDA, reflecting an excellent safety profile for use in food-adjacent, personal care, and sensitive agricultural applications.
Agnique PG 9116 UP is stable across a wide range of electrolyte concentrations, pH values (pH 3 to 12), and temperatures, providing exceptional formulation robustness in complex multi-component systems where ionic strength and pH may vary significantly.

Agnique PG 9116 UP is free from VOC, APEO, ethylene oxide residues, and preservatives, meeting the most stringent sustainability and clean-label requirements across agrochemical, home care, and institutional cleaning markets.
Agnique PG 9116 UP has over 95% bio-based carbon content, derived entirely from renewable glucose (starch) and C9–C11 fatty alcohol feedstocks, supporting sustainable chemistry and bio-based formulation objectives.

Features of Agnique PG 9116 UP:
Agnique PG 9116 UP is a yellow to brown viscous liquid at ambient temperature with a mild characteristic odor, an active matter content of approximately 50%, and a water content of approximately 50%, consistent with the standard 50% active grade of the Agnique PG 9116 series.
Agnique PG 9116 UP has a longer C9–C11 alkyl chain compared to Agnique PG 8105-G and PG 8107-G (C8–C10), resulting in higher lipophilicity, stronger hydrotropic behavior, a lower HLB value within the APG class, and enhanced compatibilizing action at oil-water interfaces.

Agnique PG 9116 UP may undergo precipitation or phase separation at low temperatures due to the longer alkyl chain length; solidified or precipitated material should be reconstituted by gentle warming to approximately 60°C and rehomogenized before use; the temperature must not exceed 60°C.
Agnique PG 9116 UP is a mild skin irritant but a severe eye irritant (Eye Dam. 1, H318), consistent with the safety classification of C9–C11 alkyl polyglucosides in aqueous solution form.

Chemical Properties of Agnique PG 9116 UP:
Agnique PG 9116 UP (CAS 132778-08-6) is a mixture of C9 and C11 alkyl mono-, di-, and oligoglucosides with an average degree of glucose polymerization of approximately 1.6, in which glucose units are linked through α- and β-1,4- and 1,6-glycosidic bonds, and the alkyl chain length of C9–C11 is longer than the C8–C10 of the PG 81xx series.
Agnique PG 9116 UP is chemically stable across pH 3 to 12 under ambient conditions; hydrolysis of the glycosidic bond may occur under prolonged exposure to concentrated acidic or strongly alkaline conditions or at elevated temperatures.

Agnique PG 9116 UP is incompatible with concentrated strong acids, concentrated strong alkalis, strong oxidizing agents, and organic solvents such as solvent naphtha, alcohols, and aromatic hydrocarbons that disrupt the aqueous solution system.
Agnique PG 9116 UP thermal decomposition or combustion may produce carbon monoxide, carbon dioxide, and irritating organic fumes; the aqueous solution is not readily flammable under normal handling conditions.

Production of Agnique PG 9116 UP:
Agnique PG 9116 UP is produced by BASF SE through the acid-catalyzed Fischer glycosylation of glucose with a C9–C11 fatty alcohol mixture under controlled temperature and pressure conditions, followed by neutralization, filtration, and adjustment to the target active content of approximately 50%; the UP designation indicates enhanced purity controls applied to the production process.
Agnique PG 9116 UP production controls alkyl chain length distribution (C9:C11 ratio), average degree of polymerization (~1.6), residual fatty alcohol content, active matter content, pH, density, and viscosity to ensure compliance with BASF product specifications for the ultra-pure (UP) grade.
