Multitrope™ 1620

Multitrope™ 1620 is a biodegradable alkyl polysaccharide. This versatile surfactant and hydrotrope has excellent stability in highly alkaline solutions and is particularly effective in high electrolyte concentration formulations. Multitrope 1620 is derived from renewable resources by the condensation of alcohol with one or more units of glucose.

Product Highlights
  • Excelllent stability and solubility in highly alkaline solutions.
  • Good wetting properties.
  • Effective hydrotroping.
  • Compatible with a variety of surfactants (anionic, nonionic and amphoteric).
  • Soluble in solutions containing high concentrations of electrolytes.
  • Non-gelling over a range of aqueous solutions.
  • Readily biodegradable.
  • Bleach stable.
Kitchen Cleaning

Multitrope 1620 is a sugar based, 100% natural surfactant. Producing a high foam lather and good detergency for removal of greasy stains, Multitro# 1620 is a versatile ingredient with hydrotrope functionality and stability in alkali systems. The lather and detergency is a winning combination for hand dishwash formulations where consumer perception of quick cleaning and high activity is paramount. In conjunction with degreasing solvents like Prifer 6813, Multitrope 1620 makes an effective oven cleaning formulation due to hydrotrope ability and stability in alkali formulations.

Fabric Care – Wash

The Multitrope range from Croda are eco-friendly hydrotropes that bring cost efficacy and high performance to many formulations. In laundry liquids, Multitrope 810 is ideal for concentrated products as a replacement for Sodium Xylene Sulfonate. Working in high pH and high electrolyte systems, this easy to formulate product brings cost benefits through lower usage levels than other hydrotropes. For a fully natural alternative, Multitrope™ 1620 gives effective hydrotroping with anionic, cationic, non-ionic and amphoteric surfactant compatibility. This natural and green additive is more than just a hydrotrope providing dose reductions, wetting, foaming and performance as a detergent to bring all round cleaning benefits to a formulation.

Solubility And Stability
Solubility in Electrolytes

Multitrope 1620 is soluble at 2.5% in the following solutions:

  • 47% Sodium hydroxide
  • 20% Tetra potassium pyro phosphate
  • 25% Zinc sulphate
  • 25% Sodium tri polyphosphate
  • 40% Potassium hydroxide
  • 40% Sodium silicate

Multitrope 1620 is soluble at concentrations up to 20% in 40% sodium hydroxide or potassium hydroxide.

Solubility In Oxidising Agents

Formulations containing oxidizing agents are used in many types of cleaning operations. The stability and solubility of Multitrope 1620 in such solutions has been determined.

Multitrope 1620 is soluble at 2% in the following:

  • Sodium hypochlorite (4% available chlorine) 20% hydrogen peroxide.
  • Tests have shown that these solutions are stable when stored at ambient temperatures for several months.
Stability in Alkaline Solutions

Multitrope 1620 is resistant to attack by strong alkalis, hence has excellent long term stability in alkaline solutions. To demonstrate this, solutions containing 7% Multitrope 1620, 44% NaOH and 49% water were prepared, stored at 20°C and monitored periodically.

The solutions are stable for at least 12 months. After storage the solutions show:

  • No evidence of phase separation or change in colour
  • No deterioration in foaming behaviour
  • No change in surface tension

Environmental Properties

Multitrope 1620 shows ready biodegradability. Multitrope 1620 has undergone a comprehensive assessment in order to determine its likely environmental fate and effect.

In order to establish the environmental profile of the product, the ultimate biodegradability of Multitrope 1620 was determined using OECD Test guidelines revealing >60% BOD28/COD and greater than >70% Dissolved Organic Carbon removal from the aqueous phase.

The degree of ultimate biodegradation is consistent with the criteria used to differentiate readily biodegradable substances. Multitrope 1620 shows reduced environmental impact. The evaluation of acute toxicity to aquatic organisms for Multitrope 1620 has revealed a low order of effect. The 48 hour EC50 to the freshwater invertebrate Daphnia magna was found to be greater than 100 mg/litre and the assessment of toxicity to Pseudomonas putida, performed to characterise the potential for adverse effects on biological treatment, revealed a similar order of toxicity with an LC 50 greater than 560 mg/litre.

Biodegradability Ultimately Biodegradable
Aquatic toxicity 48 hour EC50 Daphnia Magna min. 100mg/litre
LC50 Pseudomonas Putida min. 560mg/litre

 

Aquatic Toxicity
Algae 37 mg/l
Daphnia min. 100 mg/l
Fish 100.81 mg/l
