This application claims priority to German Patent Application No. 10 2018 218 513.1, filed Oct. 29, 2018, which is incorporated herein by reference in its entirety.
The present application describes a cosmetic composition for temporary deformation of hair, which comprises water, oil and an alkoxylated fatty alcohol and their use. In addition, a method for temporary deformation of hair using the cosmetic composition is disclosed.
For some time, the pomade has been celebrating a renaissance in men's care with the comeback of the full beard and barbershops.
Pomade has been around since the 18th century and was obtained from apples in a complex process (Italian: pomo or French: pomme).
Pomades are primarily developed to give the hair a smooth look while providing a shiny, but not oily, finish. In principle, pomades are particularly suitable for hairstyles that are shaped with a comb. Unlike gels, pomades do not dry out or do not leave hard film on the hair. The hair can thus be styled over and over again all day long.
Pomades usually make due without alcohol and synthetic styling polymers (=film-forming polymers) and therefore do not dry out the hair. Usually, pomade is an ointment-like substance composed of various fats and exists based on oil and water. The latter is more flexible and easier to remove. Oil-based products hold the hairstyle better, but are more difficult to remove from the hair.
There is still a need for styling products for head and/or beard hair that impart high holding performance to treated hairs, without including synthetic, film-forming polymers. In addition, these styling products should thus give the treated hair a natural, non-greasy or oily shine.
This object is achieved by a cosmetic composition for the temporary deformation of hair, comprising, in each case based on the total weight of the composition, a) from about 20 to about 60% by weight of water, b) from about 1 to about 20% by weight of at least one oil, and c) from about 20 to about 65% by weight of at least one alkoxylated fatty alcohol.
Surprisingly, it has been found that such a cosmetic composition for temporary deformation of hair, despite the absence of synthetic, film-forming polymers, thus imparts a high holding performance to treated hair, without making the hair appear oily or greasy. In addition, such a composition can be distributed in the hair very well and evenly.
The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
The cosmetic composition for temporary deformation of hair contains water as the first essential ingredient. The amount of water is at least about 20% by weight, based on the total weight of the composition. Accordingly, it is a water-based cosmetic composition. The amount of water in the cosmetic composition is preferably at least about 30% by weight and more preferably at least about 35% by weight, in each case based on the total weight of the cosmetic composition. Accordingly, particularly preferred cosmetic compositions amount of water is from about 30 to about 60% by weight of water and more preferably from about 35 to about 60% by weight, in each case based on the total weight of the cosmetic composition.
The cosmetic composition contains at least one oil as a second essential ingredient.
