Method for extracting substances from soapberry fruit and seed and products made therefrom
US Patent Application 20110293760
Publication Date: Dec. 1, 2011
Assignee: H-J Hsu

Discussed is a manufacturing technique for extracting active interface saponin and organic substances from soapberry; organic elements and oleic alcohol products from soapberry seeds through the process of fermentation and end products made therefrom. T

The manufacturing process includes: pre-fermentingsoapberry fruit, processing said fruit by a dialysis device, separating the soapberry flesh and fiber by a separation device, extracting soapberry dialytic liquid through a grinding and compression device and separating the fiber, eliminating bacteria inside the dialytic liquid by a large stewing device and conducting a second fermenting process with a vacuum device to generate a soapberry syrup. Said method reportedly  is healthy, toxin free and biologically safe, produce no waste, zero carbon emissions, zero pollution, low energy production and is ecologically friendly.

End products produced by said method are variables with excellent economic viability. Skin care products are: shower gel, facial gel, shampoo, bath powder, soap, facial mask, night-cream and so on. Skin care products in this innovation cover a very wide spectrum and can replace all types of skin care products. Products in this Innovation are natural, pollution free, and are more efficacy.

There are some differences in the properties of cleansing products. In this patent, they are categorized as an inorganic detergent or an organic detergent. The inorganic detergent is suitable for cleansing tableware, clothing and industrial equipment. Such cleansing agent can breakdown and decompose either acidic or alkaline chemical compound of inorganic objects, oxidize the rusts on appliances or utensils. However, such detergent cannot be directly used for cleaning up of organic substances. The organic detergent is suitable for cleansing organic substances. Organic detergent can be used for biodegrading pesticide residues in fruits and veggies, and remove the toxicity. Furthermore, it can also use as human or even pets' body cleanser, skin care and maintenance products. The organic elements of soapberry can effective clean and care for the human and pets' skin simultaneously.

High unsaponifiables and methods of using the same
US Patent Application 20110293544
Publication Date: Dec. 1, 2011
Assignee: International Flora Technologies Ltd.

Materials with high levels of unsaponifiable matter, such as extracts from plants, produce hydrolysates with unique properties. Properties that are sought in traditional saponification of natural oils are a result of low levels of unsaponifiables. These properties include high levels of aqueous surfactant activity, water-solubility or ready water-dispersability, activity as foaming agents and the like. An objective of traditional saponification processes is to increase the water-solubility and surfactant activity of naturally occurring materials.

It has been found that the application of a hydrolysis process to materials, particularly materials with a high level of unsaponifiables (e.g., at least 6% w/w), produces a product with properties significantly different from those products resulting from the conventional saponification of materials with less than 6% by weight of unsaponifiables. The resulting hydrolysates from the practice of the present invention are substantive, resisting both physical and aqueous-based removal from skin and hair, exhibit a very unique surfactant property and are not foaming agents with water. Hydrolysates according to the present invention may thus be used to enhance the performance of cosmetics and pharmaceuticals. These hydrolysates can be are bioactive agents and alternative natural carrying agents for topical application of materials, particularly for application of materials to the skin or hair of subjects, and provide a substantive support for the materials carried.

Film containing compositions
US Patent Application 20110293539
Publication Date: Dec. 1, 2011
Assignee: Colgate-Palmolive Company

Disclosed is an oral care, personal care or cleansing composition with a carrier comprising a functional material and at least two polymers. One polymer has a greater solubility in water than the other polymer; one of the polymers may be water-soluble and the other polymer water-insoluble. The polymers are selected and apportioned to provide at least one of the following: a desired stability of the film in the composition, a desired rate of disintegration of the film during use of the composition and a desired rate of delivery of the functional material during use of the composition.

Color changing cleansing composition
US Patent 8067350
Publication Date: Nov. 29, 2011
Assignee: Kimberly-Clark Worldwide Inc.

A cleansing composition is disclosed that changes color during use. The cleansing composition contains a plurality of thermochromic dyes that cause a color change to occur at a threshold temperature and continue to cause a color change over a temperature range. The range of temperatures corresponds to approximately the amount of time sufficient to properly wash or scrub using the product. In general, the present disclosure is directed to an improved cleansing composition. The cleansing composition, for instance, may comprise a body wash, a facial soap, a shampoo, a baby wash, a disinfectant, a general purpose cleaner, a window cleaner, a detergent, a vehicle cleaner, pet detergent or wash or any other suitable cleaning product.

In one particular embodiment, the cleansing composition may comprise a hand soap composition. In accordance with the present disclosure, the cleansing composition contains a color changing indicator that changes color based upon changes in temperature. Specifically, during use of the cleansing composition, the composition increases in temperature due to various factors. For instance, when the cleansing composition is intended to clean part of a person's body, such as a hand soap, the temperature of the composition may increase due to contact with the user, due to friction that is caused during washing and/or due to the presence of warm water.

When the cleansing product is used to clean adjacent surfaces, on the other hand, the temperature of the composition may increase due to friction that is generated during scrubbing, due to contact with a person's hand and/or due to the presence of warm water. In accordance with the present disclosure, once the cleansing composition reaches a selected temperature, the composition can be configured to discontinue changing color indicating to the user that the user has spent sufficient time washing, wiping or scrubbing.

Foaming compositions for hair care
US Patent 8066976
Publication Date: Nov. 29, 2011
Assignee: Galderma S.A.

The invention concerns a foaming composition for washing and treating hair and/or the scalp. In an aqueous medium the composition contains: at least an active principle selected among corticoids and retinoids, at least an anionic surfactant; at least an amphoteric surfactant and a pro-penetrating agent.

Psoriasis is one of the most common skin ailments among all chronic skin diseases. This disease is found in 1.4 to 2.9% of the population. The scalp is one of the favored sites for psoriasis; the latter causes essentially erythemas, desquamations, hyperkeratoses or pruritides and can also be responsible for a reduction in hair density. The treatments used to date involve salicylic acid, local steroids, anthralin, or coal or wood tar. These treatments are unpleasant, in particular when tar is applied, and require lengthy applications, in particular when hair ointments are used.
