| 摘要 |
The present invention provides a long-lasting hair colourant composition comprising an intimate admixture of a dye with a physiologically acceptable compatible solid base. The stick has a hardness which is sufficiently high to provide substantial dimensional stability under light to moderate manual pressure under ambient temperatures and sufficiently low to allow easy gliding of the stick over a mass of damp hair and transfer of stick material thereto under light to moderate manual pressure. The stick also contains an effective lathering component and is substantially free of alkaline soap material. |
