Surfactant-containing seamless capsules

Abstract: Surfactant-containing seamless capsules of the present invention have an inner layer and an outer layer having a film-forming material. The inner layer contains an oily component and a surfactant component. Such surfactant-containing seamless capsules are produced using in multiple nozzle of triple or more having a sequentially increasing diameter. Since the capsules are excellent in emulsive dispersibility of the content liquid and surfactant dispersibility and solubility in the oily component, they can be used in pharmaceuticals, foods, luxury foods, bath additives, detergents and other fields.

Percutaneous absorption accelerator and preparation containing same

Abstract: A percutaneous absorption accelerator and a percutaneous absorbent preparation containing the same and, more particularly, a percutaneous absorption accelerator containing either derivatives of specific glycerols or polyglycerols and alcohols as effective components and a percutaneous absorbent preparation containing the percutaneous absorption accelerators and pharmaceutically effective components.

Sheeted cosmetic composition

Abstract: PROBLEM TO BE SOLVED: To obtain a sheeted cosmetic composition applicable even to dry skin, easily washable after attached to the skin for a long time and giving extremely excellent feeling to the skin by using a new water-soluble tacky adhesive material having high adhesivity. SOLUTION: This cosmetic composition is produced by laminating a water-soluble tacky adhesive sheet and a water-soluble protecting material. The water-soluble tacky adhesive sheer preferably contains a water-soluble polymer (e.g. gelatin, dimethylaminoethyl acrylate or polyvinyl alcohol) and water. The sheet is preferably further incorporated with a functional pharmaceutical component selected from among humectant, skin-beautifying agent, ultraviolet absorber, slimming agent, blood flow accelerating agent, astringent, anti-inflammatory agent, agent for preventing and improving the formation of wrinkles, chilling agent, thermal agent and surfactant. The water-soluble protecting material is preferably a water-soluble film, nonwoven fabric, woven fabric, etc., made of gelatin, polyvinyl alcohol, pullulan, etc. The composition is preferably stored by packaging with a gas barrier packaging material.

Lipolysis acceleration method

Abstract: The present invention provides a lipolysis acceleration method which comprises orally administering a thistle-series or pepper-family plant, or an extract thereof; or dermatologically applying it by local administration or as a bath medicine composition. According to the method of the present invention, marked lipolysis acceleration effects can be obtained. It exhibits excellent effects for the control, prevention and improvement of obesity.

Weakly acidic bath salt composition

Abstract: Into a weakly acidic bath additive composition comprising a carbonate salt and an acid, a moisturizer is further incorporated. Typical examples of the moisturizer include organic acid salts such as sodium lactate; polyhydric alcohols such as propylene glycol; water-soluble polymers such as polyethylene glycol; and so on. The moisturizer functions to keep the carbon dioxide gas to stay in the bath, thereby enhances the blood circulation promoting effect of the carbon dioxide gas.

Formulations and methods for reducing skin irritation

Abstract: Compositions and methods are provided for inhibiting skin irritation attributable to chemical irritants or environmental conditions, by the application of an anti-irritant amount of aqueous-soluble divalent strontium cation.

Cleansing and conditioning article for skin or hair

Abstract: The present invention relates to a substantially dry, disposable, personal cleansing article useful for both cleansing the skin or hair, and more particularly to a disposable cleansing article having a substrate which preferably comprises of multiple layers. These articles are used by the consumer by wetting the dry article with water. The article comprises a water insoluble substrate having at least a first portion that is wet extensible and at least a second portion that is less wet extensible than said first portion and a lathering surfactant. Preferably, the articles of the present invention further comprise a conditioning component.

Cleansing articles for skin and/or hair which also deposits skin care actives

Abstract: The present invention relates to a substantially dry, disposable, personal cleansing article useful for both cleansing the skin or hair and delivering skin care actives onto the skin or hair. These articles are used by the consumer by (i) wetting the dry article with water and (ii) generating lather by subjecting the wetted article to mechanical forces, e.g., rubbing. The article comprises a water insoluble substrate, a lathering surfactant, and a skin care active component. Preferably, the articles of the present invention further comprise a deposition aid and/or a conditioning component.

Cleansing articles for skin or hair

Abstract: The present invention relates to substantially dry personal cleansing articles useful for cleansing the skin or hair. These articles are used by the consumer by wetting the substantially dry article with water and then rubbing the article against the skin or hair. The article comprises a water-insoluble substrate having non-fibrous polymeric raised areas on at least one surface of said water insoluble substrate that are formed of a polymeric material having a Shore A hardness of no more than about 80, and a lathering surfactant releasably associated with the substrate. Preferably, the articles of the present invention further comprise a conditioning component.

Personal cleansing compositions

Abstract: The present invention relates to non-abrasive personal care cleansing compositions. These compositions utilize insoluble micronized cleansing particles of defined particle size that are not tactilely perceived by the user during the cleansing process, and yet which provide improved cleansing performance from the composition. These compositions also comprise a surfactant, an emollient and water.
