Description

Title of the invention: HAIR REVITALIZING COMPOSITION Technical field

[0001] The present invention relates to a hair conditioning composition. The present invention also relates to a hair conditioning process. STATE OF THE ART

[0002] Hair is generally damaged and weakened by the action of external atmospheric agents such as light, weather conditions and / or the action of mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening.

[0003] There are many products developed to revitalize hair.

[0004] The current hair oil market is dominated by oils containing silicones. However, many consumers prefer silicone-free hair oil products, which explains the global growth of silicone-free oil products.

[0005] Therefore, it is desirable to develop Si-free oil-based hair conditioning products, which can provide a similar conditioning effect with silicone oil-based products and do not provide a greasy feeling.

[0006] It is also desired that the products be stable.

[0007] Furthermore, the formulation of environmentally friendly cosmetic products, which are designed and developed with environmental issues in mind, is becoming a major objective in an effort to address global challenges. It is therefore essential to provide more sustainable compositions to address these environmental concerns.

[0008] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good naturalness index and / or materials of natural origin and, more particularly, materials of plant origin while reducing the use of compounds of petrochemical origin. Summary of the invention

[0009] An object of the present invention is therefore to develop Si-free stable oil-based hair conditioning products, which can provide a similar or superior conditioning effect with silicone oil-based products and do not provide a greasy feeling while being environmentally friendly.

[0010] Another object of the present invention is to provide a revitalization process hair.

[0011] Thus, according to a first aspect, the present invention provides an oily hair revitalizing composition comprising: a. at least one unsaturated fatty alcohol comprising a C12-C20 carbon chain; b. at least one volatile alkane; and c. at least one fatty acid ester oil,

[0012] wherein the composition does not comprise silicone.

[0013] According to a second aspect, the present invention provides a hair revitalization process comprising applying the composition as described above to the hair.

[0014] The inventors have now discovered that with the combination of at least one unsaturated fatty alcohol comprising a C12-C20 carbon chain, at least one volatile alkane and at least one fatty acid ester, the composition of the present invention is stable and can provide the hair with a conditioning effect and a light feeling. Here, the term light feeling means no greasy feeling.

[0015] Other subjects and characteristics, aspects and advantages of the present invention will become even more apparent from the detailed description and examples which follow. DETAILED DESCRIPTION OF THE INVENTION
