  • pests may for example include insects, arachnids, weeds, fungi, or rodents.
  • polyol reads onto types of organic compounds which comprise multiple hydroxyl (-OH) groups. These compounds often exhibit sweet-tasting properties and are used in various industries, notably in the production of food as sugar substitutes and in the pharmaceutical industry. Common examples include glycerol and erythritol. More in particular, the wording "monomeric polyol” refers to a basic molecular unit of a polyol that has not been linked to any other molecules. Unlike their polymeric counterparts, which consist of long chains of repeating units, monomeric polyols are singular in structure.

  • Alkyl polyglucosides or (APGs) are a class of non-ionic surfactants derived from renewable raw materials such as vegetable oil and starch.

  • sugar alcohols include xylitol, sorbitol, erythritol, and mannitol.
  • sugar alcohols that are present in many plants, predominantly in the Rosaceae family including apples, pears and stone fruits.
  • Sorbitol is a primary end product of photosynthesis and a major translocation sugar, and can make up to 10 wt.% on fresh weight basis in fruits of common orchard crops from the Rosaceae family.
  • sugar alcohols are generally highly soluble in water, and are easy to formulate with other adjuvants in a relatively simple formulation at a high concentration as a plant protection product. More in particular, sugar alcohols were found to be highly compatible with alkyl polyglucosides, and may enhance the efficacy of the pesticide formulation.
  • Sugar alcohols were also found to be safe for the environment and humans, as well as safe for transport, storage and use. Sugar alcohols are present in the soil as has been confirmed in literature, and form part of the trophic chain: soil bacteria like Lactobacillus spp. uses and metabolizes sorbitol and other sugar alcohols. Using sugar alcohols for pest control is thus not adding any dangerous, toxic or foreign substance to the environment. Further according to literature, sugar alcohols were found non-toxic on fish, mammals and birds. Sugar alcohols thus represent a safe alternative to conventional chemical pesticides from a natural water perspective, and may support biodiversity. Sugar alcohols are furthermore not classified as dangerous substances for humans according to CLP and GHS regulations, showing that the use of these substances is safe for humans.
  • sugar alcohol based products like sorbitol do not self-ignite, are non-oxidizing, non-explosive and not highly flammable, they are considered to be safe products for transport and storage, and are safe to be used by professional farmers, gardeners and non-professional users.
