Forestall™

Forestall™

Forestall™ is a unique cationic surfactant proven to neutralise a wide range of malodours. Its low active level and full solubility in water makes it ideal for use in most air and fabric spray applications for de-odourisation. It is effective against odours caused by tobacco, vegetable smells, body odour and cooking fat.

Performance Highlights
Air Refresher

The effectiveness of Forestall as an odour neutraliser was assessed in independent tests using trained panellists. The tobacco smoke and amyl mercaptan (“rotten egg”) odours, were introduced to a 1650 cubic feet room at three times the threshold level1 for detection and fans were used to ensure uniform circulation. Forestall was introduced via a calibrated aqueous spray for 10 or 20 seconds. Fans were left running for 30 seconds before switching off and readmitting the panel testers to assess the odour level. Figure 1 and 2 demonstrate that Forestall is highly effective at low active concentration and rapidly reduces the odour to below the threshold limit, this is the lowest concentration at which the odour can be detected by humans. The atmospheric concentration is based on the 1% spray solution, hence, for a 0.1ppm atmospheric concentration the active atmospheric concentration is 0.001ppm.

Kitchen odors

A separate test was used to assess the effectiveness of Forestall at eliminating kitchen odours. 1150g of onion and 185g of garlic were chopped and placed in an odour booth for 24 hours before the evaluation and were left in the booth throughout the test. The level of malodour was evaluated before spraying (initial), immediately after spraying and at 5, 15, 30, 45 and 60 minutes after spraying. Forestall has been shown to be highly effective against onion and garlic odours showing a reduction of 47% after 15 minutes.

Fabric Refresher

Forestall and the market leading competitor product were used to treat terry towels saturated with tobacco smoke. The towels were then sprayed with an aqueous solution of Forestall. The results were assessed by a panel of experts and at a 1% concentration Forestall displays equivalent odour neutralising performance to a widely used competitor product.

Solubility

A 1% solution of Forestall in water gives a clear liquid whereas a 1% solution of a competitor odour neutraliser forms a precipitate or creates a hazy white liquid and requires the addition of a solubiliser to achieve a clear solution. Odour neutralisers based upon Forestall can be produced quickly and easily in simple blending equipment without the need for heating and the use of an additional solubiliser.

Additives for Creating Ambience

A house is not a home until an occupier has created his or her own stamp. Providing a positive atmosphere for guests couldn’t be easier with the use of permeating fragrance systems with so many scents and delivery formats for consumers to choose from.

The influence of the aromatherapy sector has put much more emphasis on creating the perfect ambience for all occasions around the home. The development of freshener sprays; both aerosol and non-aerosol, along with air freshener gels or liquid wick-type products give variety to the types of consumer products that can provide longer-term distribution of fragrance.

Key to this product sector is the use of surfactants and gelling agents to ensure fully solubilised fragrances. This leads to the reduction of alcohol levels, frequently achieving improved fragrance release and reduced alcohol notes. Croda can provide a wide range of surfactants and specialised blends for tailored air freshener systems

Benefits
  • Easy formulation of clear systems
  • Reduction of alcohol levels, and therefore flammability issues
  • Reduced alcohol notes
  • Improved fragrance release

Forestall offers a non-patented and effective way of providing odour neutralisation from a spray application. Mal odours can cause a negative feeling and ensuring that they are eliminated from the atmosphere can alleviate this.

Forward Thinking Ingredients for Modern Kitchen Cleaning

The kitchen has evolved to become a hub for activity and one of the most used rooms of a modern household. Constant utilisation means kitchen surfaces need tough cleaning solutions to tackle the daily assault of dirt and grime.

Daily cleaning is a tedious task for any household so consumers look for quick and effective solutions.

Croda can bring a number of effective products for hard surfaces designed to wet and penetrate tough kitchen soils. Multifunctional ingredients from Croda have been developed to target stains, break them down and to suspend them in the wash mix until rinsed away.

Forestall can provide an odour free environment by neutralising bad smells that are often associated with the kitchen. Spicy and herbaceous foods can create lingering odor. To quickly diminish pungency and return the kitchen to harmonious living space, Forestall from a trigger spritz is all a consumer needs.

Formulating

Forestall is supplied as an easy-to-use liquid that can be used in conjunction with anti-microbials. It is stable in acids and bases and completely soluble in water without the need for an additional solubiliser. We have found no interaction with carbonylic groups (i.e. main component of fragrances) and can be used in a variety of applications without the restriction of patents.
