Definitions

  • the invention relates to a fragrance composition
  • a fragrance composition comprising an aqueous gel matrix, a fragrance derivative which slowly releases the fragrance under the influence of protons and a protonic acid.
  • the invention relates to a method for producing these gel-like fragrance compositions and their use as an additive for cleaning agents, cosmetics, deodorants, paints and varnishes, as well as agents for the antimicrobial treatment of fabrics or for keeping insects away from waste collection containers.
  • Fragrance and aroma substances play an increasing role in the field of textile and personal care products.
  • Crucial for the perceptibility of a fragrance is its volatility, whereby in addition to the nature of the functional groups and the structure of the chemical compound, the molar mass also plays an important role.
  • Most odoriferous substances have molecular weights of up to about 200 daltons, while molecular weights of 300 daltons and more are an exception. Due to the different volatility of odoriferous substances, the smell of a perfume or fragrance composed of several odoriferous substances changes during evaporation, the odor impressions being described in "top note”, “heart or middle note” (“middle note”) or “body”) and “base note” (“end note” or “dry out”).
  • the top note of a perfume or fragrance does not consist solely of volatile compounds, while the base note largely consists of less volatile, i.e. non-stick fragrances.
  • the base note largely consists of less volatile, i.e. non-stick fragrances.
  • more volatile fragrances can be bound to certain fixatives, for example, which prevents them from evaporating too quickly.
  • a basic method for the targeted release of fragrances e.g. B. from detergents, is their direct addition to the application formulation.
  • the disadvantage of this method is the immediate release of the fragrance from the formulation, which leads to a short-term fragrance effect and thus the shelf life of the Formulation greatly reduced.
  • Added to this is the low chemical stability to atmospheric oxygen, which has been observed with numerous fragrances, especially with aldehydes and alcohols. Attempts to encapsulate such substances or to include them in cyclodextrins have been unsuccessful or uneconomical due to the high raw material prices. Immobilization by chemical derivatization proved to be more advantageous.
  • WO-A-95/04809 teaches the slow cleavage of fragrance alcohol esters by means of lipases, which produces a long-lasting fragrance.
  • WO-A-97/30687 and EP-A-816322 bind to sulfonates, sulfates and phosphates, with similar effects being achieved.
  • Further possibilities for the targeted slow release of fragrance alcohols are betaine esters, as shown in EP-A-0799885, ⁇ -tertiary carbon esters in WO-A-98/07810, ⁇ -keto esters in WO-A-98/07813 or linear or cyclic acetals.
  • WO-A-94/06441 relates to the acid hydrolysis of acetals and orthoesters, which are based on aldehydes / ketones or alcohols with fragrance properties.
  • EP-A-0820762 describes the loading of silica particles with fragrances and their use in washing powders.
  • EP-A-0281034 teaches the inclusion of fragrance compositions in inorganic polymer matrices.
  • the object of the invention described here is to provide compositions for the targeted and uniform release of fragrances over a longer period of time (“slow release”).
  • the object is achieved according to the invention by using proton-cleavable derivatized fragrances and embedding them in an aqueous gel matrix.
  • the invention relates to a fragrance composition
  • a fragrance composition comprising a
  • the slow release of the fragrances is based on the hydrolytic cleavage of the fragrance derivatives under the action of protons within the acidic gel matrix.
  • the resulting fragrances are released to the gel and must first diffuse through the enveloping gel matrix before they can reach the ambient air. Since both the hydrolysis of the fragrance derivative in the gel and the release of the fragrances thereby formed from the gel into the ambient air are diffusion-controlled, the fragrances are released evenly over a long period of time (“slow release”).
  • Suitable proton-cleavable derivatives of the fragrances are those which release the underlying fragrance in the presence of protonic acids, such as
  • esters (I) are based on esterification products of - olfactory alcohols with reactive mono-, di- and tricarboxylic acids
  • fragrance alcohols There are no restrictions on the choice of derivatizable fragrance alcohols, provided that the alcohols have the necessary fragrance properties.

  • carboxylic acids used to esterify the scented alcohols must not have a strong intrinsic odor that, after hydrolysis, has a negative impact on the odor impression.
  • Mono-, di- and tricarboxylic acids which are suitable in the context of the present invention are, for example, stearic acid, oxalic acid, malonic acid, succinic acid and citric acid.
  • the esterification of the carboxylic acids with the fragrance alcohols can be carried out by the conventional methods known to those skilled in the art.
