Definitions

  • the present description refers to a powder soap for personal hygiene and the respective method of obtention.
  • the application of a drying process according to the prior art for obtaining a powder soap may lead to the production of a fine powder with a large quantity of floating dust, and, consequently, a large volume of waste and a low sanitizing power.
  • the processes known in the prior art do not allow a structure with a high sanitizing and degreasing power to be obtained in a one-step.
  • the present embodiment is useful for storing and providing powder soap for use in public places, such as, for example, shopping malls and hotels, where significant doses of this type of product are usually necessary and where storage thereof for a long time may jeopardize its cleaning and disinfecting capacity.
  • the powder soap comprises saponified fatty acids selected from a list comprised of animal or vegetable fats, a salt, an emollient, hydrating components and additives with a particle size of 50 to 500 ⁇ m, wherein said powder soap is obtained in a one-step drying process until the humidity is less than 5% by weight.
  • the drying process is intended to remove a liquid aggregated to a solid for a gaseous phase through thermal vaporization. It is therefore a simultaneous process of transferring heat between the product and the drying air. It is also defined as a one-step process, as it is carried out quickly and without the need of secondary drying processes to achieve the desired humidity values.
  • the powder soap for personal hygiene comprises 80 - 90% (w/w) saponified fatty acids, 1-5% (w/w) of a salt, 0.5 - 2.5% of an emollient, 0.1- 5% of hydrating agents and additives.
  • the particle size of the powder soap for personal hygiene ranges from 100 to 400 ⁇ m, preferably from 150 to 375 ⁇ m and even more preferably from 200 to 350 ⁇ m.
  • the powder soap for personal hygiene further comprises essential oils.
  • the hydrating component of the powder soap for personal hygiene is selected from a list consisting of: glycerin, urea, hyaluronic acid, ammonium lactate, collagen and mixtures thereof.
  • the additives of the powder soap for personal hygiene are selected from a list consisting of: dyes, perfumes, chelating agents and mixtures thereof.
  • Another aspect of the invention discloses a method of obtaining the powder soap for personal hygiene comprising the raw material drying steps; mixture and fusion of the raw materials; mechanical pulverization with drying of the mixture obtained in the previous step so as to obtain a powder with a particle size of 50 - 500 ⁇ m and a relative humidity less than 5%.
  • the step of drying the raw material in the method of obtaining the powder soap is carried out at a temperature below 50°C, preferably from 15°C to 40°C, more preferably from 20°C to 35°C.
  • the method of obtaining the powder soap further comprises a humidity measurement and analysis step.
  • the quantity of saponified fatty acids used in the total composition of the powder soap ranges from 80 to 90% by weight, oils or saturated fats being preferred.
  • specific materials can be chosen that might improve the sanitizing power and the hydration of the user's skin, for example glycerin could be used as hydrating component and/or olive oil as emollient.
  • the olive oil may also play a role of conditioner of the user's skin, providing a sensation to the user of hydration and hygiene for longer.
  • additives may also be added such as dyes or perfumes, which act as elements that increment the sensation of cleanliness.
  • the powder soap may also additionally comprise essential oils that increase the user's hydration.
