  • a beautiful and attractive appearance is a desire for many people. Therefore, an essential part of the daily personal care of humans is focus on the hair of the head. Cleansing and shampoo products are commonly used to remove excess of soil or sebum from the hair. However, these products often leave the hair in a dry and rough condition. To address this issue many cleansing and shampoo products comprise components providing care to the hair and/or contain conditioning agents to provide a conditioning effect.
  • conditioning agents of the above products are not only to reduce the dryness and roughness of the hair. Moreover, the richness and slipperiness, as well as the gliding and combability of the hair are improved by the conditioning agents.
  • Typically used conditioning agents are silicone containing compounds. However, these are well known for the fact that silicone residues can build up on the hair. As a result these silicone residues weigh down the hair, which reduces the hair volume. Therefore, it remains desirable to provide shampoo compositions free of silicone compounds.
  • Such compositions are known in the state of the art, but compositions avoiding the incorporation of silicone compounds have drawbacks. After the application of such compounds the hair is described to be rough, dry, difficult to detangle and difficult to comb in the wet condition. In consequence compounds were included in shampoo compositions with the aim to replace the silicone components. The use of these silicone replacements has also been disclosed in prior art.
