Definitions

  • Antiperspirants or deodorants (Deo) are used to eliminate or prevent body odor, which arises when the in itself odorless fresh sweat through
  • Microorganisms is decomposed.
  • the usual cosmetic deodorants are based on different active principles.
  • deodorant In common usage there is not always a clear distinction between the terms “deodorant” and “antiperspirant”. Rather, especially in German-speaking countries, products for use in the armpit area are referred to as deodorants or “deodorants”, irrespective of the question of whether an antiperspirant effect is also present.
  • Antiperspirants are antiperspirants that - in contrast to the
  • Deodorants which generally prevent microbial decomposition of already formed sweat - to prevent the secretion of sweat at all.
  • Cosmetic products tend to develop a base odor after prolonged storage.
  • the reason for this undesirable side odor may be e.g. cosmetic oils, perfume oils, deodorants, AT agents and other agents that change chemically over time.
  • Many cosmetic products are therefore treated with antioxidants to prevent unwanted oxidation of various substances targeted and thus the
  • a commonly used antioxidant is BHT (butylhydroxytoluene).
  • BHT butylhydroxytoluene
  • ⁇ -Oryzanol (CAS: 1 1042-64-1, also referred to as Oryzanol) is a mixture of ferulic acid esters of phytosterols, notably cycloartyl ferulate, 24-methylenecycloartanyl ferulate and campesteryl ferulate.
  • Oryzanol is sold under this product name, inter alia, by the Bremen company Henry Lamotte Oils GmbH and is a white to white-yellowish, odorless crystalline, 98% pure powder of esterified with ferulic acid phytosterols (including triterpenes, camesterol, stigmasterol and ß-sitosterol) from the Germinated and bran oil from Oryza sativa L. (rice germ oil), the rice plant belonging to the grasses.
  • Oryzanol has pronounced natural UVA and UVB absorption capacity and is therefore used in sunscreen products. Furthermore, it finds use in
  • compositions as additional components which can be used in certain product forms.
  • the structurants when used, are preferably present at 1% to 30% by weight of the composition.

  • liquid fats are cured using a combination of phytosterols and esters thereof, including specifically, sitosterol and oryzanol to form an organogel.
  • DE 69723331 T2 discloses oryzanol as a constituent of UV-containing sunscreen preparations.
  • WO 02083091 A1 discloses 2.5% by weight of oryzanol in AT-containing microemulsion formulations, wherein sterol esters such as oryzanol are used to thicken the preparation.

  • the addition of any additional antioxidants is limited to a maximum of 0.4% by weight, or in particular completely omitted (0% by weight).
  • the proportion of one or more sterol esters, in particular oryzanol is advantageously selected in the range from 0.02 to 0.04% by weight, based on the total mass of the preparation.

  • the pattern without BHT shows an olfactory impression of only 50%.
  • cosmetic products contain only as little as necessary ingredients. It is particularly advantageous when raw materials are used which have a natural origin and minimize the allergy potential. Furthermore, it is advantageous if natural ingredients can be used as antioxidants which have such a positive effect on product stability that antioxidants produced industrially in large quantities, e.g. BHT can be dispensed with altogether.

  • oryzanol is shown to improve olfactometric perception, especially with longer storage times and higher temperatures.
  • the improved olfactometric perception is a measure of the perfume stabilization of the preparation.
  • perfume stability in particular perfume-free products, means the olfactory stability of the preparation after storage.
  • the preparations advantageously contain no UV filters and / or butylhydroxytoluene.
  • oryzanol is added as the sole sterol ester in the formulations of the invention, i. no further sterol esters are included in the preparation.
  • oryzanol showed improved stability, in particular perfume, ie odor stability. That after appropriate storage time, temperature (+ 6 ° C, 40 ° C) and light irradiation (Li), the oryzanol-added preparations have a constant odor effect.

Abstract

L'invention concerne l'utilisation de faibles quantités d'esters de stérol, en particulier d'oryzanol, dans des préparations cosmétiques ou dermatologiques désodorisantes et/ou antitranspirantes, ce qui permet d'éviter l'ajout de filtres anti-UV, de butylhydroxytoluol et d'autres antioxydants sans nuire à la stabilité du produit. On constate au contraire une stabilité améliorée du produit, constatée pour la stabilité du parfum et pour la stabilité de la couleur.
