Manufacture of the crystal hair rinse consists of coating the crystalline citric acid with an alcoholic solution of the other ingredients, followed by drying.
Because of the hygroscopic nature of the product, waterproof or water-repellant packaging should be used. Materials include laminated glassine, saran, saran-coated foil, polyethylene or polyethylene bonded to glassine, foil or paper. The film is formed into packets or envelopes on fully automatic or semiautomatic equipment which fills 8 to 15 gr. of the crystals into the container and crimps or heat seals both ends.
Packets should be tested by immersing a number of them in warm water and then making the required changes in the sealing operation. |
