Description
Skin and hair wash preparation The present invention concerns skin and hair wash preparations such as conditioning shampoos, body washes and shower gels, and in particular formulations which permit replenishment of the natural oils present in hair and skin.
Many types of formulations for shampoos, body washes and shower gels have been proposed over the years. Shampoo formulations in particular should be easy to rinse, provide a good finish after washing hair, result in minimal skin or eye irritation, or damage to hair, and should have low toxicity.
Over the last few years it has been of increasing concern to provide shampoo and skin wash formulations which consist primarily of natural ingredients, in order to avoid deleterious effects on either the skin or hair of the user, or indeed on the environment, bearing in mind that all skin wash preparations and shampoos ultimately have to enter a watercourse.
Many known shampoo formulations tend, to greater or lesser degrees, to strip hair and scalp of the natural vital oils which are normally to be found in or on healthy hair.
Known skin wash formulations can also undesirably strip oils and the like.
It is an object of the present invention to provide a skin or hair wash formulation having a high proportion of oils, especially natural oils, such that use of the formulation avoids undesirable stripping of natural oils from hair of a user.
According to the invention, therefore, there is provided a homogeneous skin or hair wash formulation having a pH in the range from 6 to 8, which formulation comprises the following (in which all percentages indicated are by weight): at least 50% of at least one fixed oil; at least 15 % of an alkali metal amphoacetate; at least 5 % of a lauryl betaine; at least 0.1% of a gelling agent; and an emulsifying amount of an organic emulsifying agent; a dermatologically acceptable amount of an organic acid such as citric acid, in an amount to ensure that the pH is in the range indicated above, and, optionally, one or more perfume agents, viscosity modifiers, sensory feel enhancers, and other additives conventionally included in shampoos or skin wash formulations, the balance being either incidental ingredients or non-deleterious ingredients, such that the formulation is in the form of a water-dilutable cream.
The fixed oil is typically a lipophilic long chain vegetable oil of edible quality. Such an oil may be saturated or unsaturated (and if unsaturated may be mono-unsaturated or polyunsaturated). Such vegetable oils typically have from 12 to 20 carbon atoms and may be derived from one or more of nuts, flowers or the like. Examples of suitable such oils include sunflower oil, jojoba oil, almond oil, hazelnut oil and the like. The oil employed is preferably of certifiable organic quality, such as one meeting the Soil Association certification standard and preferably includes a blend of such vegetable oils. The fixed oil is preferably present in an amount of at least 60% of the formulation.
The alkali metal amphoacetate is typically a sodium salt. Examples of suitable amphoacetates which may be employed in the formulation according to the present invention include cocoamphocarboxy-propionates, cocoamphoglycinates, coco-amphopropionates, cocoamphocarboxyglycinates, lauroamphocarboxypropionates, lauroamphocarboxyglycinates, lauroamphocarboxypropionates and lauroampho-glycinates The emulsifying agent is organic (that is, not inorganic) and is further preferably of certifiable organic quality, such as one meeting the Soil Association certification standard. The emulsifying agent may be, for example, cetyl glucoside and/or stearyl glucoside. A preferred such emulsifying agent is cetearyl glucoside (that is, a combination of cetyl and stearyl glucosides). Such an emulsifying agent co-operates with the lauryl betaine present in the formulation in order to ensure a stable formulation which works effectively as a skin or hair wash preparation Cetearyl glucoside has been found to work effectively at low concentrations (such as no more than 1.5%) and is able to handle base oils at high percentages (such as more than 20%). If other emulsifying agents such as sucrose stearate or cetearyl alcohol are used, they may need to be added in considerably larger amounts to handle large proportions of oils.
The lauryl betaine is preferably present in an amount of up to 15% by weight (more preferably up to 10%); it is present in an amount such that the skin or hair wash preparation is a white cream in the absence of colouring agents. If attempts are made to use too little of the lauryl betaine, then the formulation may be disadvantageously yellow in colour. If other apparently similar betaines, such as cetyl betaine or cocoamidopropyl betaine, are tried instead of lauryl betaine, then a cream-like product is not formed. Rather, a disadvantageous thin yellow liquid is formed.
The gelling agent is typically a natural gum, such as xanthan gum or the like. Such a gelling agent is preferably present in an amount not exceeding 2%.
An optional further ingredient is glycerine, typically present in an amount of up to 5% of the skin or hair wash formulation.
Other ingredients, such as aloe vera powder, calendula tincture which are not essential for the basic function of a skin or hair wash formulation may be included.
Such ingredients may, however, give an enhanced sensory effect or enhance the perceived goodness' of the formulation.
In some embodiments, all the ingredients in the hair or skin wash formulation may be of food-grade quality. It is further particularly preferred that all ingredients should be of certifiably organic quality.
The skin or hair wash formulation according to the invention is generally stable both physically and microbially; and lacks undesirable physical attributes such as harshness and oiliness.
The following Example of a formulation according to the invention is given by way of example only, in which all percentages are by weight.
Example
A shampoo formulation was made with the following proportions: 69.4% of organic jojoba oil; 18 % of a sodium amphoacetate; 5 % of a lauryl betaine; 0.1% of an organic (that is, of organic quality) xanthan gum gelling agent; 1.5% cetearyl glucoside; 2% citric acid; and 4% glycerine.
The shampoo formulation was used to wash 50 heads in a professional salon and compared against a leading baby shampoo (Johnson and Johnson).
The shampoo formulation according to the invention produced a rich creamy lather. It was slower to lather up than the comparative shampoo and had less volume, but it was noticeably creamier and rinsed out easily.
After rinsing and towel drying the shampoo formulation according to the invention left the hair feeling cleaner than the comparative shampoo but was equally easy to comb. Tangle removal was moderately easy. Neither of the shampoos was considered to give much conditioning to wet hair.
After drying and styling the hair there were no significant differences between the two shampoos and both products left the hair feeling clean and in good condition although flyway was not completely eliminated. In either case

Such an emulsifying agent co-operates with the lauryl betaine present in the formulation in order to ensure a stable formulation which works effectively as a skin or hair wash preparation Cetearyl glucoside has been found to work effectively at low concentrations (such as no more than 1.5%) and is able to handle base oils at high percentages (such as more than 20%). If other emulsifying agents such as sucrose stearate or cetearyl alcohol are used, they may need to be added in considerably larger amounts to handle large proportions of oils.
The lauryl betaine is preferably present in an amount of up to 15% by weight (more preferably up to 10%); it is present in an amount such that the skin or hair wash preparation is a white cream in the absence of colouring agents. If attempts are made to use too little of the lauryl betaine, then the formulation may be disadvantageously yellow in colour. If other apparently similar betaines, such as cetyl betaine or cocoamidopropyl betaine, are tried instead of lauryl betaine, then a cream-like product is not formed. Rather, a disadvantageous thin yellow liquid is formed.
The gelling agent is typically a natural gum, such as xanthan gum or the like. Such a gelling agent is preferably present in an amount not exceeding 2%.
An optional further ingredient is glycerine, typically present in an amount of up to 5% of the skin or hair wash formulation.
Other ingredients, such as aloe vera powder, calendula tincture which are not essential for the basic function of a skin or hair wash formulation may be included.
Such ingredients may, however, give an enhanced sensory effect or enhance the perceived goodness' of the formulation.
In some embodiments, all the ingredients in the hair or skin wash formulation may be of food-grade quality. It is further particularly preferred that all ingredients should be of certifiably organic quality.
The skin or hair wash formulation according to the invention is generally stable both physically and microbially; and lacks undesirable physical attributes such as harshness and oiliness.
The following Example of a formulation according to the invention is given by way of example only, in which all percentages are by weight.
Example
A shampoo formulation was made with the following proportions: 69.4% of organic jojoba oil; 18 % of a sodium amphoacetate; 5 % of a lauryl betaine; 0.1% of an organic (that is, of organic quality) xanthan gum gelling agent; 1.5% cetearyl glucoside; 2% citric acid; and 4% glycerine.
The shampoo formulation was used to wash 50 heads in a professional salon and compared against a leading baby shampoo (Johnson and Johnson).
The shampoo formulation according to the invention produced a rich creamy lather. It was slower to lather up than the comparative shampoo and had less volume, but it was noticeably creamier and rinsed out easily.
After rinsing and towel drying the shampoo formulation according to the invention left the hair feeling cleaner than the comparative shampoo but was equally easy to comb. Tangle removal was moderately easy. Neither of the shampoos was considered to give much conditioning to wet hair.
After drying and styling the hair there were no significant differences between the two shampoos and both products left the hair feeling clean and in good condition although flyway was not completely eliminated. In either case
