Description
Technical field
The present invention relates to the low viscosity personal care composition that comprises suspension particulate matter.The invention still further relates to a series of two or more low viscosity personal care compositions.
Background technology
The astringent that is known as " clarification lotion " is the low viscosity personal care composition that does not substantially comprise emulsifying agent.Astringent is administered to skin conventionally after using facial cleansing device and before using skin moisturizer.The use of astringent is considered to the replenish step in skin care regimen always, raises, thereby and skin is prepared for absorbing better wetting agent to neutralize the skin surface pH being caused by facial cleansing device.
In recent years, the use of astringent has been designed to the independent process in scheme, and the available various beneficial effects of astringent are just developed.
Wish that astringent has translucent outward appearance.Some consumers are tending towards believing that translucent astringent is than transparent astringent " denseer ".In order to realize the translucent extremely opaque outward appearance in personal care product, use habitually emulsifying technology.The system of emulsifying comprises water and oil phase.In emulsion, obtain the oil droplet that translucent outward appearance mechanism is behind fine dispersion and have the refractive index that is different from water, this causes that light is in the reflection of the interface of oil phase and water then.This luminous reflectance causes the translucent of emulsion.
But astringent has than the simpler structure of the structure of emulsion.Because being retained on skin and not, astringent is rinsed, so wish that the emulsifier content in astringent keeps low as far as possible.In addition the oil that, astringent should preferably have low content is to prevent oily skin sensation.
Except translucent outward appearance, also expect that astringent provides pure and fresh and smooth dermal sensation.Be known that some particulate matter, for example silicone resin is for this object.For example, transfer Color Access, the WO00/56272A1 of Inc relates to the gel liquid powder composition that comprises silicone resin.But, forming the low viscosity requirement that translucent outward appearance and pure and fresh soft and smooth dermal sensation should not endanger astringent, described low viscosity is less than 1000mPa.s.Higher viscosity, the feature that 1000mPa.s is gel-form composition as being greater than, these are different from astringent.
Therefore, be desirable to provide gentle, low viscosity personal care composition, it has translucent outward appearance, and pure and fresh dermal sensation is provided, and does not substantially have emulsifying agent, and is stable.In the list of references of previously having announced, neither one discloses the present invention and has met beneficial effect of the present invention.

(methyl) acrylic monomers is (methyl) acrylic acid, their any ester or any monomer of their any amide.(methyl) acrylic acid ester or amide can have any in alkyl group, aromatic group, various substituted radical, such as hydroxyl, epoxide, amine, mercaptan, carbamate, carboxyl or other substituted radical or their any combination.Some (methyl) acrylic monomerss accurately have a kind of carbon-to-carbon double bond, and other (methyl) acrylic monomers has two or more carbon-to-carbon double bonds.Some monomers are described as the ester of (methyl) acrylic acid and some alcohol in this article.Should be appreciated that this class description refers to the monomer structure of the description like this that can make by any method, comprise by (methyl) acrylic acid is reacted with some alcohol.
Acrylate copolymer is used in various industry, to provide rheological behavior to modify beneficial effect, to include but not limited to thickening capabilities already, and for the suspending power of its compositions being impregnated in wherein.Some polymer are commercially bragged about and are devoted to provide suspending power, and other polymer is bragged about for being more devoted to build viscosity.Importantly select suitable acrylate copolymer for this low viscosity personal care composition for the present invention, this can provide sufficiently high plastic yield to suspension particulate matter, and increases viscosity simultaneously with exceeding.
Be have been surprisingly found that by the applicant, can be in screening select to be suitable for use as low viscosity personal care composition in solution by screening technique for the acrylate copolymer of the suspension aids of suspension particulate matter.The selection plastic yield being provided by acrylate copolymer refers to for the plastic yield for the treatment of screened screening solution that mixes acrylate copolymer.Screening solution can be prepared according to following steps.
A) pre-determine the acrylate copolymer of amount and regulate pH to prepare acrylic acid polymer solution to approximately 6 by disperseing in water,
B) optionally, add viscosity reducers to reach low-viscosity aqueous compositions to acrylic acid polymer solution, wherein together with or the viscosity that do not make low-viscosity aqueous compositions together with the acrylate copolymer of the scheduled volume of viscosity reducers to about 500 ± 60mPa.s.
Measure selection plastic yield for the every kind of screened screening solution for the treatment of that comprises acrylate copolymer.If acrylate copolymer makes to select plastic yield for 0.11Pa at least, preferably 0.12Pa at least, it is considered to for the suitable acrylate copolymer of this personal care composition stably to make particulate matter suspend.Be not bound by theory, for the acrylate copolymer of the suitable suspension aids as this personal care composition, it is believed that favourable intersection point is present between thickening capabilities and suspending power.
