In series of structurated lipids (SL) (I), conjugates PEGn-L (2R’; R) (R’; 2R), previously characterized by primary colloidal parameters: surface tensions (σ), critical micellar concentrations (CCM) and hydrophile/hidrophobe values (HLB) representatives with high lipophily (“colloidally disadvantaged”) as a result they have limited use in horticultural and agroalimentary processing due belonging to HLB = 1-8. The objective of the paper is to ameliorates in a controlled manner of this colloidal parameters through gradual binary monitorized association “homogeneous” (n = 9,18) polyoxyethylene (structured by Williamson procedure) conjugates PEGn-L (2R’;1R) (R’; 2R) in series HLB1/HLB2 = 4/10; HLB1/HLB2 = 4/13; HLB1/HLB2 = 6/10; HLB1/HLB2 = 6/13 and ratios 10/90; 30/70; 50/50; 70/30; 90/10. Experimental results interpreted in correlation structures-HLB systems have imposed two new cumulated colloidal parameters: “homogeneous” cumulated oligomerisation degree (nCB), respectively hydrophile/hidrophobe cumulated value (HLBCB) “colloidally advantaged”. Performance of gradual binary association in this systems confirmed advantages and limits the premise for start-up and adopted work strategies.
