The invention consists of methods by which agar or an agaroid is hydrolysed under controlled conditions to give materials which form very low strength gels when 1 % solutions in water are cooled, and which, at near zero gel strengths, give dispersions which act like creams. These can be used as bases for skin treatment products, cosmetics, food and have the advantage for skin preparations of being handled like a cream but then behaving like a lotion, the cream leaving no oily residue. Twelve examples are given, including uses for cosmetics, massage gels, etc., and twenty claims are made. |
