Docket No.: 4368PCT MULTI-MODAL HAIR CARE COMPOSITION COMPRISING CATIONIC GUAR BLENDS AND PROCESS FOR PREPARATION THEREOF FIELD OF THE INVENTION

[0001] The present disclosure relates to a multi-modal hair care composition comprising cationic guar blends, and processes for preparing the same. BACKGROUND OF THE INVENTION

[0002] Hair is a keratinous filament which is subjected to various repeated stresses including mechanical stress from everyday grooming practices (such as frequent brushing and combing), environmental stress (such as UV exposure), damaging chemical treatments (such as bleaching, coloring) and thermal insult from the use of heat styling tools. The damaging effects of these exposures often manifest several types of damage to the hair fiber including structural degradation of the cortex, lifted cuticles, split ends, and other damaging effects that often result in further injury and hair breakage. Formulators of hair care and hair styling are constantly looking for products with multi-functional benefits that can effectively treat and style hair. Synthetic and nature derived polymers are widely used to achieve the desired sensory attributes to hair care. Hair styling and conditioning products encompass both fully synthetic and nature derived polymers to deliver conditioning and styling benefits. Consumers and formulators are searching for sustainable, environmentally friendly (e.g. biodegradable) and nature derived solutions. Many traditional synthetic hair care and styling polymers do not fit the sustainability criteria put forward by governmental and non-governmental entities. As such, there is increasing pressure on manufacturers of hair care and styling products to provide formulations which meet the expected care and styling benefits, while using nature derived, sustainable, biodegradable ingredients. Due to the increased demand for sustainable ingredients, the hair care industry is transitioning from using synthetic chemicals to biodegradable, nature-derived, plant based chemicals. Polysaccharides are a class of nature-derived polymers with a good sustainability profile, typically used in rinse off formulations, especially shampoos, to provide conditioning and deposition of actives.

[0003] US Patent No. 11052,033 assigned to Rhodia Operations discloses personal care composition comprising guar derivative with mean average weight average molecular weight ofDocket No.: 4368PCT about 250,000 g / mol to about 600,00 g / mol and Guar hydroxypropyl trimonium chloride having a cationic degree of substitution from about 0.20 to 0.30.

[0004] Present inventors attempt to prepare a hair care composition using nature derived and biodegradable cationic guar blends. Accordingly, the present applicant discloses cationic polysaccharides traditionally used in rinse-off formulations, that provide excellent styling and conditioning benefits to hair. By combining cationic polysaccharides of high weight average molecular weights and different degree of substitutions, it is possible to customize the styling and care benefits of formulations. The combination of polysaccharides with different chemical properties allows formulators to “dial-in” performance and aesthetic properties important to consumers, such as hair stiffness, conditioning, slip properties, humidity resistance, styleability and durability of style. Further, the cationic polysaccharides also help in mending hair split ends, protection from thermal and mechanical damage, and protection of hair from hot flat ironing up to 4500F.
