Definitions
- the invention is in the field of cosmetic and detergent formulations and relates to novel fragrance dispersions with a high content of perfume oils and verkap rare fragrances, which are characterized by a particularly high stability.
- perfume oils in detergents and cleaners allows the consumer a fragrance experience, but quickly flies after completion of the washing process and drying of the textiles.
- the formulations fragrances is added, which are present in encapsulated form.
- the capsules are such that they are stable under the washing conditions and only release the fragrances under time of mechanical stress, for example friction, if necessary, even with a time delay.
- WO 1995 016432 A2 (P & G) from 1995 describes cosmetic cleansing compositions for topical application to the skin, comprising a surfactant, a cosmetic or pharmaceutical active ingredient for hair or skin and an aqueous carrier.
- the cleaning agent disclosed in Example II is a cleansing / conditioning shampoo containing a perfume component 1 (conventional perfume oil) and an encapsulated perfume component I I, and xanthan as a nonionic polymer.
- WO 2013 026657 AI (UN ILEVER) describes drug particles whose outer surface is composed of non-ionic polysaccharides, among which u.a. Hydroxypropyl guar is disclosed as an ingredient capsule wall.
- EP 0987006 AI (BEIERSDORF) emulsions are described, which are stabilized with nanoparticles. However, these are 1000 times smaller than conventional microcapsules, so that they have a completely different dispersion behavior.
- EP 1588760 AI (I NT FLAVORS & FRAGRANCES I NC) are skin and hair treatment compositions for the controlled release of fragrances.
- Example V describes a skin cream containing a customary perfume mixture B and encapsulated perfume mixture (from Example I) and xanthan as a nonionic polymer.
- US 4428869 A (M U NTEAN U et al.) Discloses hydroalcoholic compositions for cosmetic purposes, which are known e.g. diluted with aqueous ethanol to a perfume (cologne).
- hydroalcoholic compositions for cosmetic purposes which are known e.g. diluted with aqueous ethanol to a perfume (cologne).
- Example 27 describes shampoos (III-VII, VII-VII) containing both free and encapsulated fragrances and a salt of the compound hydroxypropyl guar. The latter serves as a stabilizer for the shampoo formulation.
- the complex object of the present invention was to provide dispersions which contain up to 80% by weight of perfumes and a maximum of 40% by weight of water, with a content of from 10 to 30% by weight. % encapsulated fragrances and are distinguished by excellent storage stability with respect to the separation into different phases over at least 6 weeks both in the low, medium and high temperature range.
- Another requirement criterion was that the capsules in the dispersion of oil, water, capsules and dispersants prove to be sufficiently stable, ie the ingredients do not release in large quantities before they are incorporated into cosmetic or detergent formulations.
- the prior addition of dispersant should not affect the capsules so that they subsequently in the cosmetics and Detergent formulations release their ingredients more quickly than they would without the addition of dispersant or emulsifier.
- the invention relates to stable dispersions containing
- ingredients supplement with water and optionally further typical auxiliaries and additives to 100 wt .-%.
- microencapsulated fragrances can also be incorporated into aqueous dispersions with a high perfume oil fraction, if these are added to very small amounts of nonionic polymers, especially of hydophobe-modified hydroxyalkyl guar compounds.
- the dispersions are stable in storage for at least 4 weeks both at 5, 20 and 40 ° C with respect to the phase separation and also have a satisfactory stability for at least 4 more weeks.
- the capsules in the aqueous dispersion with hydrophobically modified hydroxyalkyl guar compounds do not release any ingredients, especially fragrances. It is of particular advantage in this case that the stabilizing effect is largely independent of the capsule material.
- capsules with walls of melamine-formaldehyde resins or polyurethane are particularly advantageous because they also prove to be particularly stable in an aqueous environment.
