Description

Improvement about fabric treatment composition
Technical field
The present invention relates to fabric treatment composition, its comprise sugared polyester (SPE) and so-called ' probiotic agent (probiotic) '.
Background and prior art
The known mankind's skin has stop (resident), instantaneous and temporary transient stop micro-flora.The mikrobe that stops is in running balance with host tissue, and micro-flora can be considered to the integration component (integral component) of normal human skin.The great majority of these mikrobes are Gram-positives, and rest on the skin surface and in folliculus.
The host has various structures, molecule and mechanism, and its restriction instantaneous and temporary transient stop thing (resident) and control stop the colony and the dominance (dominance) of thing group.These comprise various forms of local skin structures, hydration, nutrient substance and suppressor factor.The microbiota that stops ties up to be occupied niche to get into the transition state aspect with refusal is useful, and it possibly be deleterious and communicable.And stopping thing is important in changing immunity system.
Healthy skin micro-flora is kept in obvious expectation.EP 110550 proposes to use probiotic agent to be used to regulate the skin micro-flora.These can directly be applied to skin with the form of lotion or shampoo.
WO 02/028402A1 disclose the use probiotic lactobacillus be used for balancing skin under stress condition (for example uv-radiation) immunologic function with reduce skin and under such condition, produce the tendency of anaphylaxis.The carrier system of probiotic agent is food, medicament prodn or the cosmetic product that is used for oral or topical application.
WO 06/000992A1 discloses make-up composition, and it can be used to prevent and/or treat responsive and/or dry skin, handle through combine at least a divalence inorganic cation with pre-biotic microorganism.
Therefore, expectation is introduced pre-biotic microorganism and can be sent probiotic agent in the fabric treatment composition to fabric.Behind tight contacting skin, it is believed that these probiotic agent possibly transferred on the skin from fabric, possibly give aforesaid benefit.
Comprises in the compsn of probiotic agent and possibly have problems, thereby the existence of probiotics causes the excessive increase of mikrobe group in probiotic agent that this causes the reduction of product performance.Probiotics is such material, and it optionally stimulates a kind of or more kinds of microbial growth and/or activity.Sugar and glucide are included into for example sugar (monose and disaccharides) and glucide (for example oligosaccharides) of modal probiotics.Dependence is used for the metabolism of the expectation mikrobe of probiotic agent, and the many different carbon and the energy can be used in the probiotics.
The excessive increase of probiotic agent is not expected itself in compsn of the present invention, because it possibly cause the reduction of product performance.
Decomposition (for example storage after) and/or they that the existence of probiotics may be due to composition components are the material that is suitable as the probiotic agent metabolite by the probiotic agent metabolism, thereby cause the growth of unwanted probiotic agent.
Especially, be a problem for composition based on sugar, for example sugared polyester (SPE).Sugar polyester for example sucrose polyester comprises sugared body (entities), and it is connected to aliphatic chain through ester group.These sugared bodies possibly become freely can be by microbial metabolism, if ester bond is interrupted for example through enzymatic reaction or through hydrolysis.This problem is relevant with the SPE commodity especially, and it comprises lipid acid and soap impurity, and this can quicken hydrolytic deterioration SPE, as disclosed in Unilever patent WO2006076952 (A1).
When introducing fabric treatment composition as tenderizer, they oneself have the performance of expectation sugared polyester, for example improve biological degradability, reduce cost and reduce hydrophobic performance, and have no the loss of softening benefit.Obviously the fabric treatment composition that contains SPE tenderizer and pre-biotic microorganism is expectation.
BRIEF SUMMARY OF THE INVENTIONA is described
In compsn of the present invention, the problems referred to above are through in the probiotic agent compsn, using not hydrolysis SPE or utilizing this material to solve as the bacterial strain of carbon source.The stable compsn that contains SPE tenderizer and probiotic agent can be produced and be used to deposit probiotic agent and SPE to fabric.
Prior art does not hint the fabric care product that comprises probiotic agent that comprises sugared polyester, and wherein the particle of pre-biotic microorganism possibly deposit on the fabric carrier.
We have determined pre-biotic microorganism to be introduced into to comprise in the fabric treatment composition of sugared polyester (SPE) fabric softener, are used through washing to be delivered on the fabric.
The invention definition
In first aspect of the present invention, the fabric treatment composition that is used for washing methods (laundary process) is provided, it contains:
