Description

HAIR CARE COMPOSITIONS COMPRISING PECTIN AND METAL SALTS

FIELD OF THE DISCLOSURE

The present disclosure relates to hair care compositions comprising pectin, divalent metal salt of an inorganic acid, saccharide compound, and water. The disclosure also relates to methods for imparting curl definition, durable styling or shaping benefits and/or manageability to hair by treating hair with the hair care compositions of the disclosure.

BACKGROUND

Consumers desire new multi-functional hair care products that can impart good shaping and caring benefits to hair, are durable, even with several washings, and impart certain cosmetic characteristic to the hair. Such products should be pleasing to the senses, have innovative, interesting and/or pleasing textures, without loss in functional performance. Furthermore, many consumers prefer hair care products that provide a light feel, are easy to apply, and add shine and luster to the hair. Consumers also desire to use hair care products that are versatile and multi-functional such as those that can be used as rinse-off or leave-on products.

Traditional hair care products on the cosmetic market appear in various forms. They range anywhere from solutions, foams, gels, creams, waxes, mousses, sprays, serums, to aerosols and can impart a variety of levels of protection (or damage) to the hair depending on the state of the hair and the components of the product. Generally, products that are designed to impart shaping and caring benefits to hair are in the form of hair styling or hair care/hair treatment products. Such products generally contain compounds that coat the hair but which make them often sticky or tacky upon application and once dry, may become stiff and/or "crunchy" (i.e. the film is hard and brittle resulting in a crunching feel or sound when the hair is touched or in visible flaking), which is undesirable for many consumers.

Another challenge encountered in the formulation of hair cosmetic products is how to meet the hair care needs of consumers with different types of hair, such as straight hair, wavy hair, or curly hair. Curly hair, in particular, tends to significantly expand in volume and lose its curl definition when exposed to high humidity conditions or changes in humidity environment. Thus, manufacturers of hair care products continuously seek to discover new ingredients or new combinations of existing raw materials that can impart improved or enhanced benefits to different types of hair such as curly hair.

Hair style and shape formation and retention traditionally has been accomplished by the use of styling products comprising polymers and other components that at least partially coat the hair and act on the surface of hair fibers. These polymers and other components can also be called fixation polymers or fixation agents.

For temporary control, styling mousse, gels, lotions, and spray compositions have been employed to combat these conditions.

Several disadvantages are associated with these products. Loss of hair style or shape due to passage of time, elevated humidity, excessive motion, etc. may cause a consumer to feel the need to refresh a hair style throughout the day. This often requires application of additional styling product(s).

The benefits of traditional styling products also may be diminished when applied to hair to which conditioning agents also have been applied. In addition, application of materials to the surface of hair may compromise the natural feel and appearance of the hair and result in a dull appearance and/or a stiff or otherwise unpleasant feel.

Many attempts of compositions have been developed in order to conditioning, discipline and control the hair, in particular curly hair, enhancing/maintaining curl definition, curl retention, and curl regularity, and/or enhancing shine, without leaving the hair feeling and/or looking unnatural, flack and stiff.

The products of the state of the art in the gel form usually comprise in its formulation fixation polymers in order to provide curl definition and control the volume of the hair, which leaves the hair looking stiff with a non-natural effect.

However, due to the use of fixing polymers, such gel products usually leave the hair stiff with flaking effect and unmanageable after application and negatively affect the ease of combing and hair feel.

In view of the problems described above it is desirable to provide an alternative product that does not employ the traditional fixing polymers.

Also, it is desirable to provide a hair care composition that can be used after cleansing hair (damp), or on wet or dry hair and does not make the hair look and feel stiff, flack, unnatural, and unmanageable. Based on the necessity above, manufacturers seek to achieve a hair care composition, mainly for the curly hair care routine, that can improve or impart superior curl definition, and curl regularity to hair, and that can enhance or refresh the style or shape of hair without the use of traditional fixation agents and/or without having to treat the hair with a whole care routine of shampoo, conditioner, and leave- on treatments, without leaving the hair feeling and/or looking stiff, flack, unnatural and unmanageable, and having the flexibility to be used as a leave-on or a rinse-off product.

SUMMARY OF THE DISCLOSURE

The instant disclosure relates to hair care compositions that are unique in their ability to impart a variety of desirable properties to hair, especially, curly hair. For example, the compositions provide long lasting curl definition, a non-greasy feel and appearance to the hair, more bounce to the hair, and a light-weight feel to the hair as a result of their light texture. Such properties imparted to the hair can also result in frizz control, more discipline, provide styling hold, desirable volume wherein the hair is not weighted down, and impart a pleasant texture, clean and natural feel, and shine to hair. In addition, the hair care compositions of the instant disclosure have a translucid and shiny appearance and a unique and interesting texture similar to food products such as fruit jams that give the perception of nourishment or nourishing attributes.

Many consumers with curly hair seek hair care products that provide improved or enhanced curl definition. At the same time, they also seek products that prevent or minimize the frizziness of hair, particularly under high humidity conditions in which hair tends to absorb moisture causing it to be less manageable. The use of such products can enhance the visual appearance of the hair, in particular, the curl shape, and can help to keep moisture out of the hair, maintain the hair shape, and provide good manageability.

The hair care compositions of the instant disclosure contain:

(a) from about 1 wt.% to about 10 wt.% of pectin;

(b) from about 0.005 wt.% to about 0.8 wt.% of at least one divalent metal salt of an inorganic acid;

Examples

Example 1 Formulations

Table 1 - Inventive Formulation examples

^*COLORANTS (FOR EX., YELLOW 5, RED4, CARAMEL), PRESERVATIVES (FOR EX.,

PHENOXYETHANOL, SODIUM DEHYDROACETATE, SODIUM BENZOATE), PLANT/SEED EXTRACTS & POWDERS, AND FRAGRANCE The inventive formulas were prepared according to the following procedure:

In a first step, the pectin is solubilized in a main kettle in water and high shear (speed from about 1000 to about 5500 rpm, preferably from about 1500 to about 4500 rpm).

In a second step, optional compounds such as preservative, fragrance and other compounds can be added to the main kettle.

In the last step, shearing speed was lowered to a speed ranging from about 100 rpm to about 2500 rpm, and as metal salt was introduced into the formula; the shearing speed was increased and vacuum was applied).

The prepared inventive formulas can be described as being translucid and shiny and having a jelly-like appearance and texture similar to that of a fruit marmalade or fruit jam. The inventive formulas have a pH ranging from about 3 to about 4 and a viscosity ranging from about 1250 to about 2100 mPa.s.

The addition of glycerin increased the stability of the formulas.

Stability was assessed by evaluation of the bulk aspect, color, fragrance, viscosity and pH measured (as explained above for viscosity) at different times (1 month and 2 months) and at different temperatures during these periods of time (4°C, Ambient Temperature and 45 °C). Bulk stability is analyzed after temperature equalization at 25 °C.

COLORANTS (FOR EX., YELLOW 5, RED4, CARAMEL), PRESERVATIVES (FOR EX., PHENOXYETHANOL, SODIUM DEHYDROACETATE, SODIUM BENZOATE), PLANT/SEED EXTRACTS & POWDERS, AND FRAGRANCE

It can be concluded from the results in the Table 2 above that when the amount of pectin was below 1 wt.%, the compositions were not thick enough and did not achieve the visual appearance and viscosity of the inventive compositions.

Example 2 - Testing

Example 2A: Qualitative assessment on the sensory dimensions of 20 different products, including the inventive formula, with different textures and visual appearances:

Volunteers with damaged hair type I to V evaluated 20 products, including the inventive formula D, only by looking and touching the products; here was no application on hair. The damaged hair types correspond to hair that has been chemically damaged such as when hair is subjected to bleaching, dyeing, straightening, relaxing or perming processes. Type I hair is straight hair, Type II is wavy hair, Types III to V correspond to hair having curls ranging from loose curls to tighter curls.

The other 19 products contained one or more of fixative polymers, thickening polymers, cationic polymers, anionic surfactant, cationic surfactants, amphoteric surfactants, fatty alcohols, plant oils, esters, silicones, clays and fillers. Many of these other products were either heavier-looking creams or in fluid form or powdery. For each product evaluation, volunteers proceeded in the following manner: First, the volunteers gave their impressions about the product’s texture just by looking at it. Moreover, still only by looking at the product, they explained which hair care product category the product could fit into (for example, a shampoo, a finisher, a leave-in or conditioner/moisturizer). Finally, they explained why the product could or could not fit in the damaged hair category. After touching the product, they evaluated the product in the same scheme as they have done just before.

Results: The inventive formula was assessed as being in a new hair category with its unique appearance similar to that of a fruit jam and after touching the formula, the overall comment is that it can be in the category of a leave-in product.

Example 2B: Evaluation of performance on hair

The inventive formula was tested for 3 weeks by 10 volunteer consumers with curly hair, Type III to V, on their hair. No use instructions were provided. The consumers were allowed to use the product in a way they thought best.

Results: The consumers commented that the inventive formula had a light texture, provided curl definition, kept their curls defined longer, added bounce to the hair, did not make the hair greasy, and did not require use of a lot of product. The consumers found that their hair remained curly, natural, and voluminous even after the next day, hair was easy to style, easy to untangle, and easy to manage, hair had ideal volume which was long lasting, shine and soft touch, and the product provided frizz control and was easy to apply/distribute through the hair.
