Abstract

The present invention relates to a haircare product, in particular a haircare product for treating damaged hair.

Description

Title: A haircare product

Description of Invention The present invention relates to a product for application to hair. More particularly, the present invention relates to a haircare product.

Hair is generally any thread-like growth of the epidermis of a living being. More specifically, hair is a slender, elongate structure, mostly composed of keratins (fibrous, structural proteins), arising by proliferation of cells from the Malpighian layer of the epidermis in mammals (Larousse Dictionary of Science and Technology, 1995).

In more detail, hair is composed of cuboid epithelial cells which become cornified by impregnation with keratin. The outer cortex of hair contains varying amounts of the pigment melanin which determines hair colour. The medulla of the hair may contain air bubbles, and as the number increases with age and melanin production falls off the hair becomes grey. Blood capillaries supply the growing hair with nourishment and remove waste substances. The upper part of the hair projects beyond the epidermis and is kept supple by sebum, an oily secretion produced by sebaceous glands which open into the hair follicle. Sebum contains fatty acids, waxes and steroids, and spreads along the hair and onto the skin where it keeps the follicle free from dust and bacteria, as well as forming a thin waterproof layer on the skin. This not only prevents water loss from the skin but also prevents water entering the skin. (Biological Science 1 & 2, Green et al., Cambridge University Press, 1994).

Hair mostly consists of protein, although, as stated above, there are other components, e.g. melanin which gives hair its colour. Thus, any substance which can react with protein can act to damage hair. 11 050596

It is common for people to care for their hair. In particular, people wash their hair regularly, preferably on a daily basis. Caring for one's hair is beneficial so that inter alia bacteria are washed away. In other words, it is preferable to wash one's hair regularly to maintain personal hygiene. In washing one's hair, it is common to apply a specialised soap called shampoo. It is also common to apply a conditioner to hair after washing so that hair is smoothed.

In addition to bacteria, other undesirable materials can build up in hair as a result of a being's day-to-day environment. Hair can experience numerous different environments, as detailed in the following non-limiting examples. All of these environments can act to damage hair.

UV light, from exposing hair to the sun, can act to damage hair by, for example, initiating reactions between the proteinaceous hair and other chemicals present in hair and on the scalp. The build up of grease, produced by sebaceous glands on the scalp, can act to give hair a dirty appearance. Dandruff, from flaky skin cells on the scalp, can be unsightly. An aqueous chlorinated environment, from swimming in chlorinated swimming pools, can damage hair. Airborne pollution, produced by motor vehicles, factories, etc., can act to impart contaminants to hair. It is common for people to dye their hair, e.g. to provide themselves with a particular style or to hide the greying of their hair; hair dyes often contain chemicals which can act to damage hair and affect its appearance. Paints, e.g. from decorating, and other chemicals often come into contact with hair.

A common feature of these non-limiting examples of potentially damaging environments for hair is that hair often comes into contact with free radicals. Often free radicals are formed by the homolytic cleavage of covalent bonds. Homolytic cleavage can be induced by, for example, UV light, energising and breaking a covalent bond. Through homolytic cleavage, one molecule is separated into two separate parts, each of the separate parts formed by the homolytic cleavage having one free electron. The separate parts formed by homolytic cleavage are highly reactive because they each have an unpaired electron. Generally, each unpaired electron will react with another molecule, thereby starting a radical chain reaction. A radical chain reaction can be divided into three different parts:

(i) Initiation: A net increase in the number of free radicals. This can be started, for example, by UV light homolytically cleaving a covalent bond.

(ii) Propagation: The free radicals produced go on to react with other molecules to form other radicals, but there is no net increase in free radicals.

(iii) Termination: When two free radicals react together, pairing two free electrons, there is a net decrease in the number of free radicals.

Free radicals play a part in biological systems. Some free radical reactions are essential to the preservation of life, e.g. in cell signalling. However, some free radical reactions in biological systems can have a negative effect on the preservation of life. For example, the reaction of free radicals with DNA can lead to unwanted mutations in DNA sequences which can ultimately lead to cancers, or other damaging conditions. Furthermore, the reaction of free radicals with hair, for example with the proteinaceous components of hair, can cause damage to hair. Free radicals damage hair by reacting with and breaking inter alia the protein structure (e.g. keratin) of hair. Weak hair types are particularly susceptible to the damage caused by free radicals because they are already weakened compared to normal or average hair. The damage caused to hair has been detailed inter alia in the following articles: J. Photochem. Photobiol. B., 74, 109-117 (2004); Dermatol. Nurs., 7, 361-369 (1995). On a day-to-day basis, hair comes in contact with different environments which can lead to the formation of free radicals in hair and on the scalp. For example, UV light can energise contaminants in the hair, thereby forming free radicals. In another example, hydrogen peroxide, and related compounds, can be used to bleach hair blonde whilst at the same time generating free radicals in hair and on the scalp. The generation of free radicals causes damage to the hair and scalp.

Although there is currently no multi-purpose haircare product which alleviates the damage caused to hair from the day-to-day environment, a number of formulations are known which are applied to alleviate hair damage. Some known formulations used to treat damaged hair include products sold by Mastey®, Kerastase® and Hayashi System®'s 91 1 range. As will be appreciated, there is a need for new compositions and products, which can be applied to hair and which alleviate the damage caused to hair through the day-to-day environment.

It is believed that the haircare products of the present invention act to reverse the negative effects on hair of the day-to-day environment. Without wishing to be bound by theory, it is believed that the haircare products of the present invention act to mop-up and mitigate the effects of free-radicals present in hair and on the scalp which are produced as a result of the day-to-day environment. More specifically, the components of the haircare products of the present invention, either alone or in combination, act to mop-up and mitigate the effects of free-radicals present in hair and on the scalp which are produced as a result of the day-to-day environment.

Some of the components of the haircare products of the present invention, together with their sources, are set out below.

Camellia Sinesis (Green Tea) extract

Camellia sinensis is the species of plant whose leaves and leaf buds are used to produce tea. It is of the genus Camellia, a genus of flowering plants in the family Theaceae. White tea, green tea, oolong, pu-erh tea and black tea are all harvested from this species, but are processed differently to attain different levels of oxidation. Butyrospermum Parkii (Shea butter) extract

Butyrospermum parkii, commonly known as shea tree, is a tree indigenous to Africa. The shea fruit consists of a thin, tart, nutritious pulp that surrounds a relatively large, oil-rich seed from which is extracted shea butter.

Tocopheryl acetate (vitamin E acetate)

Tocopheryl acetate, also known as vitamin E acetate, is often used as a vitamin supplement, and has the molecular formula C₃iH₅₂03 (for 'a' form) (structure from the CAS® registry):

This compound is the ester of acetic acid and tocopherol (vitamin E). It is often used in dermatological products such as skin creams.

Tocopheryl acetate is used as an alternative to tocopherol itself because the phenolic hydroxyl group is blocked, providing a less acidic product. It is believed that the acetate is slowly hydrolyzed once it is absorbed into the skin, regenerating tocopherol and providing protection against the sun's ultraviolet rays.

Retinyl palmitate (vitamin A palmitate)

Retinyl palmitate, or vitamin A palmitate, is the ester of retinol (vitamin A) and palmitic acid, with formula C₃₆H₆o0₂ (figure from the CAS® registry):

Retinyl palmitate is a synthetic alternative for retinyl acetate in vitamin A supplements, and is available in oily or dry forms. It is a common vitamin supplement, available in both oral and injectable forms for treatment of vitamin A deficiency.

Retinyl palmitate is also a constituent of some topically-applied skin care products. After its absorption into the skin, retinyl palmitate is converted to retinol, and ultimately to retinoic acid (the active form of vitamin A present in Retin-A).

Spathodea Campanulata (fire tulip) extract

Spathodea Campanulata (fire tulip) is commonly known as the African tulip tree or Flame-of-the-forest. The tree has reddish-orange or crimson campanulate flowers. Manufacturing protocol for each formulation:

Tables 1 , 2 and 3 detail different formulations according to different embodiments of the present invention. The names of the ingredients, assigned by the International Cosmetic Ingredient Dictionary and Handbook (INCI), in the formulations are given in the left hand column of each table.

Trials:

With a view to confirming the efficacy of the different embodiments (i.e.

formulations) of the present invention, each of the formulations detailed in the tables were tested on 10 different subjects' hair. The 10 different subjects in each case had different hair types; 4 had fine hair, 4 had treated (e.g. dyed) hair, and 2 had normal hair.

The shampoos were applied to the subjects' hair in aqueous conditions, massaged for 1 to 2 minutes and then rinsed away.

The conditioners and masks were applied, left for 5 minutes and then rinsed away. The leave-in conditioners, restructurant, rebalancer and scalp fluid were applied and not rinsed away, i.e. left in the hair to leave naturally over a period of time, e.g. 10 minutes to 24 hours, 0 minutes to 12 hours, 10 minutes to 6 hours, 10 minutes to 5 hours, 10 minutes to 4 hours, 10 minutes to 3 hours, 10 minutes to 2 hours, 10 minutes to 1 hours, 10 minutes to 30 minutes or 10 minutes to 20 minutes.

In all cases, the subjects commented that their hair was softer and more manageable than compared to prior to application of each particular product. In every case, an improvement in the strength and gloss of each subjects' hair was observed.

On the same subjects, half-and-half tests were carried out to compare the effect of the formulations of the present invention with known haircare products, which products are said to have anti-damage effects. In a half-and- half test, half of a subject's hair is applied with a first product, whilst the other half of the subject's hair is applied with a different product. The formulations of the present invention were compared to known products of Mastey®'s haircare range, Hayashi System®'s 911 haircare range and Kerastase®'s haircare range. In all cases, the formulations of the present invention were found to improve a subject's hair more than the known formulations. In particular, application of each of the formulations of the present invention was found to result in hair which was softer and more manageable than the same hair (i.e. the other half of a subject's hair) applied with known formulations. After application of the haircare products of the present invention, the treated hair was less oily, lighter and shinier, when compared to the same hair treated with known formulations. Compared to the known Mastey® products, e.g. sold under the names Traite, Restore, Enove and Use Me First: the shampoo formulations of the present invention resulted in more foam and the hair was left softer. The conditioner formulations and the mask formulations of the present inventions gave more shine, greater combability and better resistance to hair; after each treatment the hair in each subject was evidently easier to comb and looked shinier and smoother. The leave-in conditioners of the present invention gave less buildup and more gloss.

Compared to the known Kerastase® products, e.g. sold under the names Bain Satin, Bain de force, Masque volumactive, Masquintense, Sublimateur Jour, the formulations of the present invention resulted in hair being softer and lighter.

Compared to the known Hayashi System® 911 products, e.g. sold under the names Conditioner and Texturizing rinse, the formulations of the present invention resulted in hair being more conditioned and less oily.

After application of the shampoos of formulations 1 , 4, 7, 8, 10 a subject's hair was clean, soft and manageable. Once dried the hair was shiny, smooth, soft and healthy. During the application a soft creamy lather was produced which was rinsed out easily. In cases of dry hair, the shampoo did not worsen the condition, as can be seen with standard, known shampoos. The conditioners of formulations 3, 6 and 9 were applied on damp hair, left for 3-5 minutes and rinsed thoroughly. The subject's hair was soft and easy to comb after the rinsing and when dried it was shiny, smooth, soft and healthy. The anti-dandruff conditioner of formulation 9 resulted in an evident reduction of dandruff flakes compared to pre-application of the anti-dandruff shampoo of formulation 9; after application there was no worse itching or irritation. On all hair types, the conditioners showed no build-up effect. This is particularly helpful with fine hair types because they are particularly susceptible to buildup.

The leave-in conditioner of formulation 1 1 left the hair in good condition in comparison to before application, and also in comparison to the application of other known leave-in conditioners, e.g. the leave-in conditioners sold by MASTEY® under the names HC Formula, LiquidPac and Magnesium. On all hair types, the leave-in conditioner showed no build-up effect. This is particularly helpful with fine hair types because they are particularly susceptible to build-up.

The scalp fluid of formulation 14 caused no irritation when applied to sensitised scalps, with a remarkable decrease of flakes.

The masks of formulations 2 and 5 leave hair soft, smooth and easier to comb than prior to application of the masks.

The active restructurant of formulation 12 was found to improve the body and the strength of the hair to which it was applied.

The pH rebalancer of formulation 13 was found to prevent and/or reverse damage caused to hair by chemical treatment, e.g. hair dyes, and to restore the natural pH of hair, even at the cuticle surface.

As can be seen from the above results, it is clear that a product in accordance with the present invention is able to reverse and alleviate the damage caused to hair by its day-to-day environment.
