Enhancing the performances of non-ionic surfactants

▌ Brenntag EMEA Cleaning Service Unit – Campus UAB (Universitat Autònoma de Barcelona)

Brenntag Cleaning Seminar | Heeze, October 10th 2019

OBJECTIVE & MOTIVATION

▌To shape a Product Development & Service Unit in Household and I&Icleaning market with EMEA dimension, building partnership either withcustomers and/or principals.

▌Development of formulations, ingredients, tailor made solutions:

▌Formulations: Lower content in solids and total cost raw materials, Handling energysavings, Favourable CLP.

▌Ingredients: Scale Inhibitors, and Enhanced non ionic surfactants.

▌Tailor made solutions: Under customer demand or Brenntag proactivity.

ENHANCING THE PERFORMANCES OF NON-IONIC SURFACTANTS

The development is based on:

▌R&D activity of interaction surfactant – polymer

▌Development (2009 – 2016)

▌Enhancing the Efficiency of LF and DF non-ionic surfactants: BFS – 211

▌Development (2017 – 2019)

▌Enhancing the Efficiency of Primary Alcohol Ethoxylates: BFS – NI 247/75

BFS - NI 247/75 is fluid and homogeneous at a Temperature lower than 20ºC, so it is easy to handle, it helps to avoid possible dosing problemsduring production time, and also decreases energy consumption.

Procedure:

The emulsion properties of 2 MEDIUM quality benchmark degreasers were tested against the basic AEO formulation and against BFS formulation.

Under controlled mixing, an O/W emulsion was created mixing different quantities of cleaner product and oil. Its stability was evaluated after 5minutes.

▌ Brenntag has developed LF/DF & PAE aggregates whose performance properties offer cleaners’ formulatorsalternatives to traditional LF/DF & PAE surfactants with a competitive relation efficiency - cost.

▌ Cleaning Laboratory has been studying BFS – 211 & BFS – NI 247/75 use as ingredients into ADW, HDLD,HSC for Household and I&I markets.

▌ Conclusions of our study shows that:

▌ BFS – 211 can be used as a LF/DF non-ionic surfactant instead of fatty alcohol EOPO, in ADW, and Rinse Aids.

▌ BFS – NI 247/75 can be used as a primary non-ionic surfactant instead of C12-14 Fatty Ethoxylated Alcohol with 7 OE, inHDLD in a relation 1 : 0.60 (as solids), in HSC in relation 1 : 0,4 to 0,6 (as solids), a lower % without any negative influencein performance results.

▌ Relevant optimization of the global detergent process has been introduced: lower energy consumption, lowercontent of active raw materials, savings in handling and transport.


▌Summary

CREATING THE CLEANING SOLUTIONS INDUSTRY!
