A spray foam formulation used to form a spray foam insulation layer in a wall structure is described. The formulation may include the reaction product of a polyisocyanate compound and a polyol compound; a fire retardant chosen from at least one of a non-halogenated fire retardant; and a reactive halogen-containing fire retardant, and a carbohydrate. The spray foam insulation layer has an insulative R value of 3.0 to 7.2 per inch, and a density of between about 0.3 to about 4.5 pcf. Further, spray foam insulation made from the spray foam formulation may have fire retardant characteristics that are equivalent to or better than a similar spray insulation foam insulation using non-reactive halogenated fire retardants such as tris(1-chloro-2-propyl)phosphate (TCPP).

The present invention discloses a 3-aryl-benzofuranone compound in which R.sub.1-R.sub.6, in the formula are mutually independent H or C.sub.1-C.sub.20 alkyls, and R.sub.7 is C.sub.7-C.sub.20 alkyl or C.sub.7-C.sub.20 mixed alkyl. The present invention also discloses a composition of 3-aryl-benzofuranone compound and the preparation method. The 3-aryl-benzofuranone compound and the composition thereof has the superiority in application due to the characteristics of less proneness to volatilize, less proneness to be extracted, higher resistance to migration and less proneness to bloom and precipitate on the surface of organic materials, and with a wide range of application, it is effective during the application.

The lightweight footwear of the present invention maintains excellent durability and improves heat resistance, so that contraction percentage due to a change with the passage of time is significantly low, rarely causing deformation, and thus, the lightweight footwear may be used in a high temperature and sanitary environment. In addition, the present invention solves the problem of the occurrence of premature foaming due to injection molding and a pattern on the appearance due to dispersion failure, thereby facilitating injection molding.
