Abstract: Particles, particularly washing, cleaning and/or care product particles, particularly washing, cleaning and/or care product particles, having a bulk weight greater than 450 g/l, particularly 500 g/l to 1200 g/l, characterized in that the particles have a compound mixture and fine-particulate surfactant particles, which have a particle diameter d50 ranging from 0.05 mm to 0.6 mm, a dust value of =0% to a maximum of 0.1%, at least 1% by weight to a maximum of 30% by weight of a surfactant, and at least 10% by weight to a maximum of 40% by weight of sodium carbonate. The indicated weights refer to the total weight of the fine-particulate surfactant particles, comprise, at least in part, discrete surfactant particles, and have a dust value ranging from =0% to =0.2%.

Abstract: The invention relates to a neutralization and granulation method wherein a neutralizing foam is used as granulation adjuvant. The neutralizing foam was previously obtained by mixing an anionic surfactant in its acid form, which was expanded using a gaseous medium, and a highly concentrated, aqueous alkaline component, which was expanded using a gaseous medium. The neutralizing foam has an average pore size of less than 10 mm, preferably less than 5 mm and especially less than 2 mm.
