A kind of method for assessing personal care product or hydration effect of its composition, methods described includes：Select Part I fresh plant tissue；Part I plant tissue is handled with the personal care product or its composition；And treated Part I plant tissue is heated to 35 to 80 DEG C of drying temperature.
Description
The application is Application No. 201480039428.5, entitled " method for assessing effect of personal care product "
Divisional application.
Technical field
The present invention relates to a kind of method for assessing personal care product or hydration effect of its composition.Especially the present invention is related to
And the method more rapidly and immediately assessed using producing is to the hydration work(of personal care product such as skin or hair care product
The detection of effect.
Background technology
The personal care product for improving the state of skin or hair be often designed to by influence skin or hair absorb and/
Or keep the ability of moisture to play a role.Regrettably, however the benefit of such product will not be felt by user at once,
And can actually expend a few hours, even a couple of days reuses to obtain consumer-realizable benefit.
Internal and external instrument detection to the hydration status of tissue is often laboratory that is complicated and/or being related to costliness
Equipment.In addition, it is such detection often obtain numerical parameter, its for unprofessional person indigestion or at least with desired production
Product effect is connected.
The present inventor thereby determined that so the need for there is provided the method for the hydratability that can prove cosmetics, still
This method does not need particular device and/or easily connected with consumer's interests.
U.S. Patent Publication US4,373,382 (Nicole A.A.Brun) discloses a kind of production for determining to be ready to use in skin
The method of the aquation of product, wherein product to be measured is applied at least a portion of the first vegetable sample such as apple surface,
And at least another untreated sample of first sample and same vegetables under identical reservoir conditions together with store, and
And compare the surface change of these samples.
Although US4,373,382 method is not necessarily to the instrument of complexity, and effective by the state change of vegetables base material
Ground illustrates consumer benefits, but this method still needs consuming a couple of days or a few weeks longer to show obvious effect.Therefore, US4,
373,382 method is not suitable for needing situation that is quick or even showing product efficacy immediately.Such situation is included for example, storehouse
Deposit or point of sale explanation.
The present inventor by providing specific method it has now been discovered that can improve some or all of drawbacks described above.
The content of the invention
In a first aspect, the invention provides a kind of method of the hydration effect for assessing personal care product or its composition,
Methods described includes：

The selection Part II fresh plant tissue wherein in step (i)；With control agent product treatment in step (ii)
The Part II；Treated Part II is also handled in heating stepses (iii)；
And further, wherein then step (iii), methods described includes assessing treated Part I
The step of at least one attribute (iv), planted wherein the evaluated attribute is treated Part I relative to fresh
The change of thing tissue and/or characteristic relative to treated Part II；With
The duration of wherein described heating stepses (iii) is 10s to 1 hours；
Wherein described plant tissue includes petal, leaf or combinations thereof.
2nd, according to the method for the 1st, wherein the control agent is water.
3rd, according to the method for the 1st or 2, wherein the characteristic is outward appearance and/or engineering properties.
4th, the method according to foregoing any one, wherein the plant tissue includes petal.
5th, the method according to foregoing any one, wherein in step (ii), the Part I plant tissue bag
Waterborne liquid processing containing the composition.
6th, according to the method for the 5th, wherein concentration by weight of the composition in waterborne liquid be more than it is described into
Divide the concentration by weight in the personal care product.
7th, the method according to foregoing any one, wherein the duration of the heating stepses (iii) is 1 to 20 points
Clock.
8th, the method according to foregoing any one, wherein the heating stepses (iii) are included treated plant group
Knit and contacted with stream of hot air.
9th, the method according to foregoing any one, wherein the drying temperature is less than 70 DEG C.
10th, according to the method for the 9th, wherein the drying temperature is in the range of 40 to 70 DEG C.

Fresh plant tissue is found to be the base material to moisture-sensitive, and is visually often noticeable.Separately
Outside, by using the drying temperature from 35 to 80 DEG C, plant tissue can cause rapidly and vision-significantly change because drying
Become, and without heat-caused infringement, for example, burn, burn, bubbling, boiling or other cook.
By considering following detailed description and embodiment, every other aspect of the invention will become more readily clear.
Embodiment
The method of the present invention includes step (i) and selects Part I fresh plant tissue.The plant tissue can be whole
Individual plant, flower, leaf, petal, stem, fruit, seed or root, and/or their fragment.More preferably petal, leaf or it
Combination because these are typically relative thin, but with big surface area, and therefore drying is relatively rapid.It is optimal
Plant tissue described in selection of land is petal or its fragment, because petal is generally more crisp for leaf, and therefore for
Drying shows visually more noticeable change.
The plant tissue of " fresh " means that tissue is not dried by water content less than 30% (by weight), and
It generally has the water content of 60-95% scopes.The method of the present invention is preferably used removes tissue (for example from plant living
