ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a novel herbal skin care formulation and a process for the preparation thereof. More particularly, the present invention relates to a natural herbal skin care formulation in the form of a cream.
The formulation is useful to clean and restore skin of the individual user by providing a formulation using aloe gel and essential oils to repair damage and promote supple skin. The invention also relates to a cream formulation which may provide temporary relief of minor pain and in particular, dryness of skin.
BACKGROUND OF THE INVENTION
Everyone has faced the discomfort of dry, chapped hands at one time or another. Not only hands but other external portions of the body particularly foot are susceptible to dryness, irritation and lesions. Over the years, many different compounds and formulations have been used for cleaning and restoring skin. A variety of skin creams and lotions are used to soften skin, repair lesions, combat dryness and reduce roughness in irritated skin. There are also a variety of creams or ointments that are used to reduce the itch from insect bites. Prior art formulations however either act as moisturizers to soften the skin or provide healing for skin lesions and skin cracks.
Also most of the prior art skin care formulations also include ingredients that are not always eco-friendly and are therefore economically unviable. Some of the prior art formulations also contain components that are ultimately harmful to the skin.
Increasingly, the use of natural products for manufacture of skin care products is becoming common. Skin repair products having soaps, detergents, plant extracts and the like are commonly used in this field.
In the art,
Aloe vera
is known to yield a gel which cleans and softens skin (U.S. Pat. Nos. 5,882,666; 5,874,094). Aloe gel has been used as it is a moisturizing agent and antibacterial, antifungal and even antiviral properties of the gel has been demonstrated. Aloe gel polysacchrides have immunomodulatory properties. It is very useful for burns (T. Reynolds and A. C. Dweck, J. Ethnopharmacology 68, 1999, 3-37).
In the prior art, several naturally occurring essential oils are known to act as cooling agents and to have excellent sedative effect. For example, rose water obtained when rose oil is extracted from flowers of
Rosa damascena
by steam distillation has been used as a cooling agent during summer. Rose water is also known to be sedative and calming and is used for palpitation and related problems in Indian systems of medicines (Clare Maxwell-Hudson's Aromathrapy massage book, 1994).
Sandalwood oil obtained from the wood of sandalwood tree, is known for balancing the skin, and for calming sensitive, dry or dehydrated skin. The oil is beneficial also for acne, eczema and chapped, dry skin. Sandalwood is also used in religious ceremonies and plays a key role in Indian Ayurvedic medicines. It is widely used in perfumery for its base note and classic oriental scent and is known to calm and cool the body (The Wealth of India—Raw Materials, 1994).
Vetiver oil extracted from the roots of vetiver grass by steam distillation is known in the art as being sedative, calming and antiseptic. It is used in massage blends and for acne. It is cultivated in India. (A. H. A. Farooqi and Sushil Kumar 1998, Proceedings of 2
nd
Australian Aromatherapy Conference, Sydney pp.1-13).
Germanium oil extracted by steam distillation of the whole germanium plant is known as an anti-depressent and an excellent relaxant for those suffering from nervous tension. The oil is rich in gentle alcohols, geraniol and linalool. It is suitable for all skin and good for acne treatments due to its anti-microbial effect. (Clare Maxwell-Hudson's “Aromatherapy Massage Book”, Dorling Kindersley, 1994).
