Abstract: The present invention relates to a seaweed-based composition comprising water, a seaweed powder and an additional component, said additional component being chosen from the group consisting of glucomannans, galactomannans, native starch and combinations thereof. Preferably, the red seaweed selected from the families of Gigartinaceae, Bangiophyceae, Palmariaceae, Hypneaceae, Cystocloniaceae, Solieriaceae, Phyllophoraceae and Furcellariaceae or combinations thereof.

Abstract: This invention provides a carrageenan mixture comprising about 60% to about 95% by weight of iota-carrageenans and about 5% to about 25% by weight of lambda-carrageenans, which is useful as an ingredient of a cosmetic formulation such as a fully natural hair styling gel being free from synthetic polymers.

Abstract: This invention relates to microcapsules based on gelatin and anionic polysaccharides of low molecular weight which may contain solid or liquid matters, prepared by coacervation. The aqueous polysaccharide solutions which may be used present a low viscosity, the value of which is a function of the nature of the polysaccharide; for a concentration of 15 g/l, it is, at 75.degree. C., generally between 1 and 20 mPa.s. These polysaccharides are depolymerization products of natural products:alginates, carragheenans, pectins and pectates, carboxymethylcelluloses, carboxymethylguars and carboxymethyl starches. The microcapsules may be isolated and dried.
