Description

Title of the invention: Hair revitalizing composition and hair revitalizing process. FIELD OF THE INVENTION

[0001] The present invention relates to hair conditioning compositions comprising (a) at least two cationic surfactants; (b) at least one fatty alcohol; (c) at least one alcohol ester; (d) at least one nonionic polymer; (e) at least one fatty acid; and (f) at least one fatty compound, and mixtures thereof. The invention also relates to a method for conditioning hair, particularly curly hair. CONTEXT OF THE INVENTION

[0002] People use various cosmetic and personal care compositions to improve the appearance and feel of keratinous fibers, such as hair.

[0003] Particularly with regard to curly hair, consumers are always faced with problems related to curl definition such as frizz, volume, and shape. Curly hair tends to frizz and increase significantly in volume when exposed to high humidity, chemical treatments, and other factors. Furthermore, curl shape and definition are lost after sleeping.

[0004] Numerous attempts have been made to develop products intended to discipline, define and control hair, especially curly hair, by strengthening / maintaining curl definition, curl retention and curl regularity, without giving the hair an unnatural and stiff feel and / or appearance, but these products have resulted in additional problems or maintenance difficulties.

[0005] The standard routine for curly hair includes the use of several cosmetic products all over the length of the hair and must be renewed every three days, as curls tend to lose their definition and fresh appearance after this period - it is a very time-consuming routine which involves consumers repeating all the steps approximately every three days, including washing the hair and applying different cosmetic products.

[0006] It is desirable to have a hair cosmetic product for curly hair that not only helps define curls, but also offers lasting cosmetic benefits to the consumer's hair, such as frizz resistance, leaving hair shiny, and is easy to apply and does not leave any residue. a feeling of wet or heavy hair, which improves with the use of such a product.

[0007] The formulation of environmentally friendly cosmetic products, designed and developed with environmental considerations in mind, is also becoming a major objective in an effort to address global challenges. It is therefore essential to offer more sustainable compositions to meet these environmental concerns. In this context, it is important to develop new cosmetic compositions with a lower carbon footprint, particularly by promoting the use of renewable raw materials and / or materials with a high naturalness index and / or materials of natural origin, and more specifically, materials of plant origin, while reducing the use of petrochemical-derived compounds.

[0008] Consequently, there is still a need to develop curly hair revitalizing compositions that do not weigh down the curls, so that they regain their original shape. The object of the present invention is to form an effective film to seal the cuticle of curly hair, so that it remains hydrated and not weighed down.

[0009] The present invention has overcome the drawbacks of the prior art and has resulted in a new silicone-free and sulfate-free hair cosmetic composition designed for curly hair offering quick rinsing and curl definition.

[0010] The inventors of the present invention have obtained, in a surprising and unexpected manner, hair cosmetic compositions, particularly designed for curly hair, comprising (a) at least two cationic surfactants; (b) at least one fatty alcohol; (c) at least one alcohol ester; (d) at least one non-ionic polymer; (e) at least one fatty acid; and (f) at least one fatty compound other than (b) or (e), and mixtures thereof, which are capable not only of penetrating the hair fiber without accumulating on the surface of the fiber, but also of providing curl definition until the next wash, long-lasting curl definition, frizz control, a natural look and desirable volume, and which do not give the hair a heavy appearance, but also provide cosmetic benefits such as shine, a smooth feel, and ease of application.It was also discovered that these cosmetic benefits were more pronounced with multiple applications of the product (cumulative effect).

[0011] The present invention aims to provide hair conditioning compositions that do not weigh down or flatten the hair, maintain waves, or create a frizzy appearance. These compositions allow curls to retain their waves without the need for frequent washing. to redefine style, they bring suppleness, movement and shine, and make hair less prone to breakage.

[0012] Furthermore, a light film forms on the surface of the hair, and the active compositions adhere to the inside of the hair fiber, restoring the emollience removed by shampooing, thus providing ease of styling and curl definition. Summary of the invention

[0013] The present invention relates to hair revitalizing compositions comprising: (a) at least two cationic surfactants; (b) at least one fatty alcohol; (c) at least one alcohol ester; (d) at least one nonionic polymer; (e) at least one fatty acid; and (f) at least one fatty compound other than (b) and (e).

[0014] The present invention also relates to a hair revitalization process comprising applying the composition described above to the hair, then rinsing the hair with water after an optional exposure period.

[0015] The inventors have discovered that the hair conditioning composition according to the present invention can provide high fusion and rapid hair transformation due to the combination of cationic surfactants with fusion agents such as esters and fatty alcohols. Because of the nature and lightness of the film formed on the hair surface, the shape of the curl structure itself is expected to achieve a more natural appearance, close to its natural form. This is unlikely with a thicker film deposit, which makes the hair prone to losing definition, shape, and curl movement.

[0016] To achieve the objective of the invention, numerous raw materials in different ratios and concentrations were tested to obtain the best performance in terms of definition, frizz control, and smooth curl texture. The invention was designed to achieve improved sustainable parameters such as biodegradability as an alternative to a petrochemical ingredient—a functional application for bio-based ingredients in hair care. Furthermore, the composition of the present invention can be used to restore emollience removed by shampoo, primarily for curly hair. Additional subjects, features, aspects, and advantages of the present invention will become even clearer upon reading the detailed description and examples that follow.
