Emollient Patents (Class 514/873)
  • Patent number: 8496918
    Abstract: The present invention is directed to a series of polymeric glyceryl esters that have two different molecular weight ester chains, one solid and one liquid, which when combined into a single molecule make a polymer that is solid, but has very unique flow properties. These materials find applications as additives to formulations in personal care products where there is a desire to have a structured film (provided by the solid fatty group) and flow properties, (provided by the liquid fatty group). These compounds by virtue of their unique structure provide outstanding skin feel.

  • Patent number: 5939457
    Abstract: A method for reducing signs of aging in human skin. The method includes the steps of (a) topically applying to the skin a hydroxy acid product having at most a hydroxy acid concentration of approximately 7.0% and having a pH range of between 3 and 4 which causes an increase in exfoliation of the skin; (b) topically applying to the skin a non-hydroxy acid product; (c) repeating steps (a) and (b) at least twice daily for approximately four weeks; and (d) repeating only step (b) at least twice daily for approximately another 4 weeks.

  • Patent number: 5925338
    Abstract: The present invention is directed to a clear antiperspirant or deodorant gel composition which exhibits reduced staining while retaining excellent aethetic attributes and efficacy. The gel composition is a water-in-oil emulsion having a viscosity of about 50,000 to 250,000 cP, preferably about 100,000 to 200,000 cP. The water phase comprises about 75 to 90% of the composition and contains a deodorant or antiperspirant effective amount (e.g. about 3 to 25%) of an antiperspirant active dissolved therein. The oil phase comprises about 10 to 25% of the composition and contains a silicone oil and a polyether substituted silicone emulsifying agent. The silicone oil comprises a mixture of a non-volatile silicone, preferably a non-volatile linear silicone, and a volatile linear silicone. It has been found that reducing the amount of non-volatile silicone in the known gel composition to a relatively low level (e.g. below about 5%) and adding an amount of volatile linear silicone to the composition (e.g.

  • Patent number: 5919398
    Abstract: An oil-water mixed composition is consisted of a solid or semisolid oil phase at room temperature, and a water phase which is dispersed into the oil phase. The water phase contains a humectant and is solid or semisolid at room temperature. Preferably, the oil phase contains hydrophobic silica, dextrin fatty acid ester or polyvalent alcohol oligo ester of long chain monocarboxylic acid and long chain dicarboxylic acid. The oil-water mixed composition is superior in stability with passage of time and safety. In addition, this composition has demonstrated little stickiness and sensation of unsuitability for skin, and has much emollient effect (i.e., to prevent the skin from dryness) and is persistent in preserving its emollient effect.

  • Patent number: 5916568
    Abstract: A flash-dry disinfectant composition for use as a hand wash is described. The composition consists of a C.sub.2 -C.sub.5 alcohol, a hydrogen peroxide solution and a bacteriostatic skin emollient. The C.sub.2 -C.sub.5 alcohol is preferably isopropanol. The composition contains at least about 15% to about 35% by weight of hydrogen peroxide solution in order to ensure a bacteriacidal effect with short term exposure to the composition. The composition has broad application in the food and health care industries. The advantage is a flash-dry disinfectant which may be used in place of lengthy scrub procedures effectively destroying bacteria without known risk of evolutionary resistance and which requires no towels or associated paraphernalia.

  • Patent number: RE38141
    Abstract: The present invention are dry-feel emollient compositions comprising jojoba oil based esters that have use in personal care, cosmetic, cosmaceutical and pharmaceutical products. These compositions are essentially solid at room temperature, can be provided in various shapes and sizes (especially as particulates such as spheres), and can be produced from combinations of fatty alcohols, isopropyl esters and wax esters obtained from the oil contained in the seed of the jojoba plant. These new compositions also increase the range of applications for cosmetic compositions through an emollient that is more polar and hydrophilic than is found in jojoba oils. The compositions of the present invention may be obtained by a novel process of a base catalyzed alcoholysis reaction between jojoba oil and an alcohol, such as isopropyl alcohol.
