The invention relates to a wax composition comprising linear hydrocarbons, branched hydrocarbons and oxidized hydrocarbons, wherein the composition is characterized by a congealing point from 68° C. to 110° C., an acid number in the range of 3 to 30 mg KOH/g, a saponification number of 20 to 90 mg KOH/g and a needle penetration at 25° C. of below 15 1/10 mm. The invention further relates to an aqueous dispersion comprising the wax composition and a method of manufacture of both the wax composition and the dispersion. The wax composition can be used to fully or partially substitute Carnauba wax or Candelilla wax.

Wax composition comprising linear hydrocarbons, branched hydrocarbons and oxidized hydrocarbons, aqueous dispersion thereof, method to produce such wax composition and dispersion and use thereof as Carnauba wax replacement

The invention relates to a process for manufacturing a gypsum slurry by bringing together and mixing gypsum, water, wax powder and optionally other components, applying the gypsum slurry in a process for manufacturing a gypsum product and a gypsum product such as a plasterboard or wallboard obtained by the process and the use of the wax powder for the manufacturing of a moisture resistant gypsum product.

Process for manufacturing a gypsum slurry or a gypsum product with the use of a wax powder, products obtained by the process and use of the wax powder for obtaining a moisture-resistant gypsum product

A process for obtaining a wax fraction from a feed wax, the process comprising: (a) providing a molten feed wax in a container; (b) solidifying the feed wax by cooling; (c) increasing the temperature of the feed wax to a temperature at which a first fraction of the feed wax melts, said first fraction having a congealing point which is lower than the congealing point of the feed wax; (d) recovering the first fraction of the feed wax; (e) increasing the temperature of the remaining feed wax to a temperature at which a further fraction of the feed wax melts; and (f) recovering the further fraction of the feed wax. The feed wax comprises at least 75 wt.-% of linear alkanes and each recovered fraction comprises at least 19 wt.-% of the feed wax.

Process for obtaining wax fractions from a feed wax

The invention relates to O/W wax dispersions based on water, an emulsifier and a wax phase containing predominantly aliphatic hydrocarbons and polar compounds having chain lengths of at least 18 carbon atoms, and also plaster compositions comprising the O/W wax dispersion, and the use of the O/W wax dispersion.

O/W wax dispersions and gypsum products obtainable from these

A method of treating or refining a wax includes hydrogenating a feed wax which has an MEK-solubility oils content of more 0.5 weight % to provide a hydrogenated wax. Thereafter the hydrogenated wax is de-oiled to reduce the MEK-solubility oils content of the hydrogenated wax, producing a refined wax or a wax product.

Treatment of wax

The invention relates to a wood composition containing olefin and raw wood materials, the use of said olefins for rendering raw wood materials water repellent, and a method for producing wood materials therefrom. The raw wood materials contain or are made of lignocellulose and are provided in the form of fibers, strands, or chips.

Wood composition containing olefins, use of olefins for rendering raw wood materials water repellent, and method for the production of wood materials

The invention relates to a candle base material having components that allow the candle to change from opaque to transparent at a desired temperature.
