Features & Benefits

Fast dissolving, wide spectrum fragrance solubiliser

ECO NatraSense WS is an effective low-dosage, fast dissolving universal fragrance solubiliser well suited for formulations where low levels of surfactant are used. ECO NatraSense WS surfactants are available as part of Croda’s 100% renewable, 100% bio-based ECO Range of surfactants. As VOC regulations increase and solvent use is limited, ECO NatraSense WS excels in quickly solubilising a broad range of fragrance classes in water based systems. By using ECO NatraSense WS, formulators can rely on one solubiliser to work with many different fragrances instead of choosing a solubiliser on a case-by-case basis.

Certified Sustainable Palm Oil Derivatives – Mass Balance

ECO NatraSense™ series is Croda’s sustainable palm oil variant allowing customers to use sustainably sourced material if they wish. The products are manufactured by the RSPO’s Mass Balance system. The Mass Balance supply chain allows certified sustainable palm oil material and non-certified material to be mixed throughout the supply chain but administratively monitors the mass of certified material produced and sold. The Mass Balance system is fully audited allowing buyers of the material to view the products life span. Another advantage of this system is that it actively encourages palm growers to produce sustainable palm and move towards a segregated supply chain system. By choosing these ingredients, you contribute to the production of sustainable palm oil. Products manufactured with sustainable palm oil do not in any way compromise on performance.

Performance Benefits
  • Works effectively across many fragrance classes
  • Lower dosage rate than other fragrance solubilisers
  • Dissolves quickly and produces a clear solution

Performance results
ECO NatraSense WS can be used at significantly lower dosage rates compared to other commonly used fragrance solubilisers. For example, twice as much NPE-9 is required to solubilise d-limonene than ECO NatraSense WS and over three times as much PEG-40 castor oil is needed compared to ECO NatraSense WS.

ECO Range

ECO NatraSense WS is manufactured using ethylene oxide derived from bio-ethanol, resulting in 100% renewable surfactants with performance identical to petro-based options. These 100% bio-based products eliminate the need to choose between high performance and fully renewable ingredients. By using an alternative route to ethylene oxide with bioethanol from biomass sources, it significantly increases the bio-based content of ethoxylated products and reduces reliance on fossil fuels. Additionally, ECO NatraSense WS is manufactured with high levels of renewable energy. Sustainability informs and guides our development strategies and is an integral part of our business. ECO NatraSense WS addresses the consumer demand for more sustainable products and aids our customers in meeting their own sustainability goals, while delivering high performance products to the market.

100% Bio-based ECO Range

Sustainability is in our DNA. It is integral to everything we do. From the raw materials we source and the way we use them, to the ingredients we create, we believe in being a responsible company. We are pleased to introduce our new ECO range of 100% bio-based surfactants. Over 50 products make up the ECO range made by using bio-based ethylene oxide (EO) which we manufacture from biomass ethanol. Coupling the use of bio-based EO with the high proportion of renewable energy used at the manufacturing plant, leads to a significant reduction in carbon footprint for the ECO product range. Formulators can now access 100% renewable surfactants without sacrificing performance to help meet increasingly demanding sustainability targets.

Making Ethylene Oxide Sustainable

With increasing consumer demand for renewably sourced and sustainable products, we are pleased to introduce our new ECO range of 100% bio-based surfactants. In recent years, “greener” non-ethoxylated ingredients have been used in the pursuit of more renewable formulations, but the performance has not met the levels achieved when using traditional ethoxylates. With significant investment at our Atlas Point manufacturing site, located in Delaware, USA, our plant is the first of its kind in the US to produce bio-based EO from bio-ethanol (Figure 3). This development enables the production of sustainable and bio-based ethoxylates (Figure.1)

Avoidance of Greenhouse Gas (GHG) Emissions

Converting landfill gas to electricity and steam avoids the release of methane into the atmosphere, which has a global warming potential 25 times greater than CO2 when measured over 100 years. Our use of landfill gas since 2012, combined with the reduction in our usage of natural gas, has led to an aggregate reduction in GHG emissions of close to 1 million tons CO2e. Annually, the amount of avoided emissions is a figure equivalent to our total combined Group 1 and 2 emissions.

Improved Bio-based Content

Chemically equivalent to petrochemical-based ethoxylates, Table 1 shows the improvement in bio-based content for key surfactant chemistries when produced using our bio-based EO.

Carbon Footprint of ECO Range

We have used SimaPro software to model the cradle-to-gate life cycle analysis (LCA) of our ECO product families, focused on the climate change impact category, following the technical specification ISO 14067. The high proportion of renewable energy available at Atlas Point, along with the use of bio-based EO, leads to a significant reduction in carbon footprint for a typical ECO product family, when compared to traditional ethoxylates made using petrochemical-based EO and without renewable energy (Figure.4)

Certified Bio-based Content

Our new ECO range helps formulators meet renewability targets. Table 2 lists the BioPreferred bio-based content requirement of a finished formulation under a product category. Replacing petrochemical based surfactants for ECO range products will improve bio-based content of the formulation. All ECO products are being registered on the USDA BioPreferred Program.

Renewable Energy at Atlas Point

In 2012, we invested in a renewable energy project at our Atlas Point manufacturing site located in Delaware, USA (Figure 3). This investment saw the installation of a 3.5 mile pipeline from a local landfill site so that we could purchase local landfill gas. The gas feeds two combined heat and power (CHP) units and a multi-fuel boiler to generate electricity and steam for the plant. In 2014, we further invested in solar panels at the site, which reduced our annual carbon dioxide (CO2) emissions by 11,600 tons CO2e. By quarter two of 2020, a third CHP unit will be installed, increasing our capacity for generating electricity and steam from landfill gas and increasing the estimated percentage of the site’s energy being renewably sourced to above 30%.
