Abstract
Compositions for combating ectoparasites, and particularly head lice and their nits comprise a low viscosity linear polysiloxane combined with a higher viscosity linear polysiloxane and at least one spreading agent. The low viscosity linear polysiloxane has a viscosity of less than 10 cSt and is present in a weight percentage of 30-40% of the formulation, while the higher viscosity linear polysiloxane has a viscosity of greater than 90 cSt and is present in a weight percentage of 35-65%.
Claims
- 1. A composition for killing ectoparasites and/or their ova, comprising 30-49 wt.-%, based on the composition, of a low viscosity linear polysiloxane having a viscosity <10 cSt, 35-65 wt.-%, based on the composition, of a higher viscosity linear polysiloxane having a viscosity >90 cSt, and at least one spreading agent.
- 2. The composition according to claim 1, characterized in that the spreading agent is selected from the group consisting of medium chain triglycerides, coconut oil, palm kernel oil, babussu oil, glycerol triacetate, jojoba wax, cetearyl isononanoate, cetearyl octanoate, isopropylmyristate, isopropylplamitate, ethylhexylpalmitate and cocoyl caprylocaprate.
- 3. The composition according to claim 1 or 2, characterized in that the composition comprises at least one of 2-10 wt.-% of medium chain triglycerides and 1-5 wt.-% jojoba wax as spreading agent, the percentages being based on the composition.
- 4. The composition according to claim 1 or 2, characterized in that the low viscosity polysiloxane is dimethicone having a viscosity of 1 cSt and the higher viscosity polysiloxane is dimethicone having a viscosity of 100 cSt.
- 5. The composition according to claim 3, characterized in that the low viscosity polysiloxane is dimethicone having a viscosity of 1 cSt and the higher viscosity polysiloxane is dimethicone having a viscosity of 100 cSt.
