Abstract
The invention relates to a hydrocarbon mixture that contains at least two hydrocarbons that are different from each other, the number of carbons thereof differing by more than one, wherein said two hydrocarbons that differ from each other make up at least 60% by weight, preferably at least 70% by weight of the total of the hydrocarbons. The invention also relates to the use of said hydrocarbon mixtures and to cosmetic and/or pharmaceutical preparations containing said hydrocarbon mixtures.
Claims17
A hydrocarbon mixture which comprises:
- at least two different hydrocarbons selected from the group consisting of linear C17 and linear C19 hydrocarbons, and linear C19 and linear C21 hydrocarbons;
- at least one of 1-octadecanol and 1-eicosanol when the hydrocarbon mixture comprises the linear C17 and the linear C19 hydrocarbons;
- and
- at least one of 1-eicosanol and 1-docosanol when the hydrocarbon mixture comprises the linear C19 and the linear C21 hydrocarbons;
- wherein:
- when the hydrocarbon mixture comprises the linear C17 and the linear C19 hydrocarbons, then (i) 50-90% by weight is linear C17 hydrocarbons based on the sum of hydrocarbons in the hydrocarbon mixture, (ii) 10-50% by weight is linear C19 hydrocarbons based on the sum of hydrocarbons in the hydrocarbon mixture, (iii) the weight ratio of linear C17 hydrocarbons to linear C19 hydrocarbons is 1.5 to 3.5, and (iv) the at least one of 1-octadecanol and 1-eicosanol is present and has a concentration up to 10% by weight;
- when the hydrocarbon mixture comprises the linear C19 and the linear C21 hydrocarbons, then (i) 50-90% by weight is linear C19 hydrocarbons based on the sum of hydrocarbons in the hydrocarbon mixture, (ii) 10-50% by weight is linear C21 hydrocarbons based on the sum of hydrocarbons in the hydrocarbon mixture, (iii) the weight ratio of linear C19 hydrocarbons to linear C21 hydrocarbons is 1.5 to 3.5, and (iv) the at least one of 1-eicosanol and 1-docosanol is present and has a concentration up to 10% by weight;
- and
- the at least two different hydrocarbons make up at least 60% by weight based on the sum of hydrocarbons in the hydrocarbon mixture.
