Description

COMPOSITIONS WITH SILICON TECHNICAL CUSTOMS The present invention relates to compositions containing silicone and to the use thereof in various household products such as personal care products, household and laundry cleaners, bleaching compositions and the like. In particular, it relates to lipophilic compositions which contain if based on flavors, perfumes, refrigerants or anti-microbial agents such as lipophilic and which show improved residual character, impact and / or efficacy on surfaces treated therewith, for example. , teeth, dentures, skin, hair, laundry, dishes, work surfaces and the like. Rdernas, refers to bleaching compositions containing silieon further containing bleach-sensitive ingredients such as perfumes, sabotans and the like and showing improved stability.

BACKGROUND The lipophilic compositions such as flavor, perfume, refrigerant and disinfectant compositions are widely used either directly or in a variety of household products including cosmetics, oral and denture compositions, bleaching, dish washing, mild detergent products. laundry and to clean hard surfaces, etc., A common problem encountered with the Jipofilicas components is to improve the surface susiantivity or residual character of the lipophilic component. It would be desirable; in many, if not most, domestic applications, improve the residual surface character of the lipofLes in order, for example, to provide enhanced flavor or impact to the animal or increased antimicrobial efficacy. Modern dental hygiene and denture preparations, for example, typically contain anti-plaque and anti-tartar agents, as well as anti-microbial agents and sabotagers. The antimicrobial action can affect plaque formation either by reducing the number of bacteria in the mouth / dentures or by killing said bacteria trapped in the film to prevent further growth and metabolism. The flavorings can alleviate the problem of bad breath by means of a desodopzante action. Some antimicrobial agents, for example, menthol, can serve as breath deodorants. However, the effectiveness of the antirnicrobial agents depends largely on their intraoral / denture retention, particularly their retention on the surface of the teeth or dentures where the plaque is formed. A typical disadvantage of known dental preparations is that only a relatively short time during which the teeth are being cleaned or the mouth is being rinsed, is available for antipu crobial agents in the preparations to take effect. The problem is compounded by the fact that toothpaste preparations are used without frequency: most are used once, or perhaps twice a day. As a result, the long period between brushing for a majority of the population provides optimal plate-forming conditions. In many other personal and domestic applications, it would be desirable to provide improved surface substantivity. Laundry detergents, for example, would benefit by increasing the substantivity of perfume in the fabrics in order to provide impact to the p > Erfurne increased in clothes after washing or during use. The increased antirnicrobial substantivity would also be beneficial from a point of view to reduce the bad smells associated with sweat or other soils. The improved perfume substance would also be valuable in fine fragrances and perfumed cosmetics. The improved refrigerant substantivity, on the other hand, will be beneficial in cough / flu products. Therefore, there has been a need to develop lipophilic compositions having residual character of improved surface, impact and / or antirnicrobial efficacy. The use of lipophilic compounds such as perfumes, flavorings and the like in the bleach-containing compositions can also raise the number of problems, especially the loss of perfume or character or knowing intensity as a result of an interaction with the bleach. The effectiveness of the bleaching agent can also be carried out adversely. In this way, it would be desirable to improve the stability and efficacy of bleaching compositions containing bleach-sensitive ingredients. It is known to include silicones in dentifrice compositions, presumably to coat the teeth and prevent cavities and stains. For example, Great Britain patent application 589,579 describes a mouth rinse containing an organopolysiloxane to prevent adhesion of, or to remove tar, stains, tartar and food particles from the teeth. Mouthwash may include antiseptic compounds, such as thymol, and sabotagers or perfuming agents. The patent application of E.U.A. No. 2,805,814 discloses dental preparations including, in combination, a higher aliphatic acid amide of a mocarboxylic acid compound as an active and a silicone compound. The patent notes that silicone compounds have been proposed for the prevention of adhesion or to facilitate the removal of tar, stains, tartar and the like from teeth. The silicone compound is said to act as a smergistico to improve the antimicrobial activity and acid inhibition of the active ingredient. It is said that cyphenethyl polysiloxanes are effective in particular. Savory oils and / or menthol may be included. The patent application of CU. . 3624120 discloses quaternary ammonium salts of cyclic siloxane polymers for use with cationic surfactants, bactericides and as anticapogenic agents. Accordingly, the present invention provides a lipophilic composition of flavor, perfume, coolant, antimicrobial or other that has substantial of surface, impact and / or efficiency.
