Description

Active for textile treatment

5 Technical field

The present invention relates to the use of squalene in a laundry treatment composition. More specifically, the present invention relates to the use of squalene in a fabric softener composition to increase the comfort of washed textile materials.

Background and prior art

The feeling of discomfort in clothing that is associated with sweating can take one of two forms depending on the level of sweat production. In conditions of high sweat production, clothing can become saturated with sweat.

15 Wet areas of clothing are then contacted with the skin causing discomfort from local cooling and adhesion.

In conditions of low sweat production there is sweat or high humidity in some spaces between the skin and the first layer of clothing and within the clothing immediately adjacent to the skin. Water vapor will gradually spread through clothing in the surrounding air.

The textile bibliography identifies a high level of humidity in the space between the skin and the first layer of clothing as one of the key reasons for discomfort in low exercise environmental conditions. Similarly, discomfort may arise from the accumulation of liquid water on the inner surface of textile garments.

25 A known approach to this problem is to increase the speed of liquid water transport through the textile by increasing the capillarity or wet rate. This is achieved by decreasing the contact angle of the water on the fiber surface. This approach has the disadvantage that the total amount of water retained in the textile also increases. This leads to increased thermal conductivity and increased adhesion when these areas touch the skin. Both effects increase the discomfort experienced in use.

It is known that certain materials, such as zinc oxide (ZnO) and titanium oxide (TiO2) have the ability to change the properties between hydrophilic and hydrophobic under different environmental conditions, see for example J. Am. Chem. Soc. 2004, 126, 62-63 and Soft Matter 2005, 1, 55-61. There are several publications that describe the effect of ZnO and

TiO2 as surfaces that can make the hydrophobic / hydrophilic change. WO 2004/108846 describes the use of TiO2 as a coating in combination a siloxane to achieve an easy to clean surface and describes that it can be applied to textile materials. US 2005/0186871 A1 describes a gas permeable apparatus comprising a structure that includes a plurality of surfaces, comprising at least one of the electret surfaces, at least one light source for exposing the at least one of the surfaces comprising the photocatalyst to the photons of light sufficient to activate the photocatalyst, allowing the structure to filter particulate materials, absorb liquids by capillarity, disinfect, and deodorize the surfaces.

Photocatalysts such as TiO2 are incorporated into the surfaces of clothing products such as protective goggles to decompose and oxidize chemical substances absorbed onto photocatalyst surfaces with

45 light absorption with sufficient energy to generate an electron-hollow pair in the photocatalyst. The electron-hollow pair leads to the decomposition of surface contact with water and subsequent reactive chemicals on the surface of the photocatalysts. Coated surfaces can also function as air filters, air vents, capillary absorbent surfaces, protective covers, layers on underlying materials, and act as protective filters in ultraviolet light for the underlying materials and the body.

WO 2008/058831 (Unilever) describes a fabric softener composition comprising a fabric softener compound of 5 to 50% by weight, preferably 5 to 25% by weight of the composition of a material (material HH) capable of changing its hydrophobic / hydrophilic properties in response to an activation stage.

55 The pending application for processing not yet published by the authors PCT / EP2008 / 059818 describes a cleaning and / or laundry care composition comprising a photobleach and a pro-fragrance.

The authors of the present invention have now found that the use of squalene in a fabric softener composition can increase the comfort of the textile material during use. An increase in the moisture transport of the skin and a reduction in the humidity in the space between the skin and the first layer of clothing and within the clothing immediately adjacent to the skin are also achieved.

Invention Statement

In a first aspect of the invention the use of squalene is provided in a fabric softener composition, comprising a fabric softener compound, to increase the comfort of the textile material, in which moisture transport of the fabric is increased. skin, or where moisture is reduced in any space between the skin and the first layer of clothing and within clothing immediately adjacent to the skin; and in which squalene is capable of changing its hydrophobic / hydrophilic properties in response to an activation stage.

5 Summary of the invention

The idea of the invention is to reduce the level of water retained in the region of the textile close to the skin, while facilitating the movement of water through the textile, in order to increase the comfort of the textile material. This is achieved by creating different surface properties on the fibers in different regions of the textile (whether different regions of the garment, or different sides of the textile). Textile areas that are close to the skin become hydrophobic, while areas of the textile that are far from the skin become hydrophilic. In this way it is possible to increase the water transport without increasing the water retention properties of the textile. Increasing the transport of water and also decreasing at the same time the amount of water retained on the textile surface closest to the skin provides a beneficial effect. It is possible to maintain the comfort for the user in conditions of low sweat production, this

15 is, in conditions of little exercise, with mild weather, etc., or at least delay the appearance of discomfort when the user is exposed to such conditions.

The key to this approach is to generate different local fiber properties after the uniform treatment of the textile with a laundry product. By depositing squalene on the textile in the laundry treatment, the areas that are close to the skin can become hydrophobic, while the areas of the textile away from the skin can become hydrophilic by an activation stage. It is preferred that the activation stage uses local environmental conditions. For example, in a preferred embodiment the squalene is photosensitive and the outer side of the garment is exposed to light, particularly to UV light, and becomes hydrophilic, while the inner side of the garment near the skin and therefore Both sheltered from sunlight remains hydrophobic.

25 Important aspects of comfort include increased moisture transport of the skin and reduced moisture in any space between the skin and the first layer of clothing and within clothing immediately adjacent to the skin.

Squalene

Squalane can be deposited on the textile material from a rinse conditioner and can "change" the properties of hydrophobic to hydrophilic or vice versa after exposure to certain conditions that can be used in the invention. The activation stage that produces the change in properties can be based on photosensitivity, change

PH, temperature change, heat flow, ionic strength change, enzymatic activity, etc. The most convenient activation stage is based on photosensitivity, particularly to UV light, since it is easily possible to expose the outer side of the garment to sunlight, during use and / or drying, while protecting the side inside of the garment.

Preferred squalenes are those that undergo photo fission to generate more hydrophilic fragments from a hydrophobic precursor.

Squalene is generally deposited so that 0.2 to 1%, preferably 0.2 to 0.5% by weight of the textile material is applied after drying. Squalene is usually present in an amount of 0.5 to 15%,

Preferably 1 to 10% in the fabric softener composition.

The photo-fission rate can be controlled by the presence of photo whiteners.

In the context of the present invention, squalene is a chemical species, which is a precursor of more hydrophilic species (or one more precursor of them) after exposure to light in the presence or absence of an active photobleach.

Squalane is a terpene. Terpenes are derived from isoprene units, which has the molecular formula C5H8. The basic molecular formulas of terpenes are given by the formula:

55 (C5H8) n

where n is the number of isoprene units that bind. The isoprene units can be attached to each other "head to tail" to form linear chains or can be arranged to form rings.

The number of carbon-to-carbon double bonds in squalene is 6.

The squalene is a terpene, in which n = 6. The squalene is a triterpene, it has 6 double bonds and linear structure.

In the context of the present invention a "photobleach" is any chemical species that forms a species

Di-, tri-acyl glycerols, phospholipids, glycolipids, diol lipids, waxes, sterol esters and tocopherols.

5 Plant lipids have the necessary complement of antioxidants to prevent oxidation. During the isolation of plant oils some of these antioxidants are reduced but sufficient level remains. These antioxidants, which include vitamin A in several of its forms (retinol, retinal and retinoic acid and its carotenoid precursors, provitamin A) and vitamin E, can be added to the HH material to control the photofragmentation rate.

Preferred food lipids include amaranth oil, olive oil, palm oil, canola oil, sunflower seed oil, wheat germ oil, almond oil, coconut oil, grape seed oil, rapeseed oil, oil Castor oil, corn oil, cottonseed oil, safflower oil, evening primrose oil, peanut oil, poppyseed oil, palm, palm kernel oil, rice bran oil, sesame oil, bean oil of soy, jojoba oil.

15 Preferred food lipids also include oils and fats of animal origin that include squalene (also present in olive oil and wheat germ oil), butter and semi-fluid Indian buffalo butter. To avoid the allergic reaction, certain nut oils (peanut oil, for example) are less preferred.

A particularly preferred class of HH materials is that of terpenes.

Terpenes are derived from isoprene units, which has the molecular formula C5H8. The basic molecular formulas of terpenes are given by the formula:

25 (C5H8) n

where n is the number of isoprene units that bind. The isoprene units can be attached to each other "head to tail" to form linear chains or can be arranged to form rings. Suitable for use in the present invention are preferably linear.

Preferred terpenes of the present invention are those in which n = 3 to 8.

The number of carbon to carbon double bonds is from 3 to 8, preferably 6.

35 The most preferred terpene is squalene, in which n = 6. Squalene is a triterpene, it has 6 double bonds and linear structure.

Preferred oils may be selected from the group consisting of soybean oil, grapeseed oil, castor oil, hexadecane and squalene, preferably squalene.

Another class of preferred lipids are the sugar fatty esters described below in fabric softener materials.

The most preferred HH materials contain at least 20% by weight of a compound comprising the remainder.

where R1 and R2 are organic groups that contain carbon, hydrogen and oxygen. A preferred example is linoleic acid.

Lipids containing particularly preferred fatty acids contain 10% by weight or less of moieties containing three double bonds (such as linolenic acid). The most preferred lipids also contain less than 15% by weight of saturated acids and less than 15% by weight of acids with less than 14 carbon atoms. Within these preferred limits, branched chain hydroxyl acid moieties are included.

The most preferred oils exclude those of high linolenic content (preferred <10%), such as hemp oil (∼25% by weight of linolenic acid), and oil originating in nuts.

According to the present invention, a laundry care composition comprising a photobleach and an HH material is provided.

In the context of the present invention a "photobleach" is any chemical species that forms a reactive bleach species with exposure to sunlight, and preferably is not definitively consumed in the reaction.

Preferred levels of the photobleach present in the composition are from 0 to 0.01% by weight, preferably from 0.00005 to 0.05%.

Some of the photobleaching agents give color to the textile material. To give the fabrics an attractive white shade, it is preferred to use blue or violet shading dyes in combination with the photobleaching agents. Alternatively, a combination of photobleach is used to generate a white tone.

10 Preferred colorants are described in WO 2005/003274 (Unilever) and WO 2005/003277 (Unilever). Particularly preferred shading dyes are direct bisazo dyes, particularly those of direct violet type 9, 35 and 99 and azine acid dyes such as acid violet 50 and acid blue 98. Alternative shading dyes are described below. Dyes can sometimes act as photosensitizers.

15 Bleaching Catalysts

As noted above, photobleach suitable for use in the present invention include singlet oxygen photobleach and radical photobleach. 20 singlet oxygen photo bleachers:

The singlet oxygen photobleach (PB) works as follows:

25 PB + light -PB *

PB * + 3O2 -PB + 1O2

The photo whitener molecule absorbs light and reaches an excited electronic state, PB *. This excited electronic state 30 is inactivated by triplet oxygen, 3O2, from the surroundings to form singlet 1O2. Singlet oxygen is a highly reactive bleach.

Suitable singlet oxygen photobleach can be selected from water soluble phthalocyanine compounds, particularly metallized phthalocyanine compounds in which the metal is Zn or Al-Z1 where Z1 is

Fabric softener compound

The fabric softener compound that is different from the HH material. Suitable softening compounds of textile material are described below.

(i) Fatty sugar derivative

The fatty sugar derivative is a liquid or soft solid derived from a cyclic polyol or a reduced saccharide, said resulting derivative being esterified or etherified in 35 to 100% of the hydroxyl groups in said polyol or in said saccharide. The derivative has two or more ester or ether groups independently linked to a C8-C22 alkyl or alkenyl chain.

The sugar fatty derivatives of the invention are also referred to herein as "derivative-CP" and "derivative-RS" depending on whether the derivative is a product that is derived from a starting material of a cyclic polyol or a reduced saccharide respectively.

Preferably the CP-derivative and the RS-derivative contain 35% by weight of tri-esters or higher, for example at least 40%.

Preferably 35 to 85%, more preferably 40 to 80%, even more preferably 45 to 75%, such as 45 to 70% of the hydroxyl groups in said cyclic polyol or in said reduced saccharide are esterified or etherified to produce the CP derivative. and the derivative-RS respectively.

For the derivative-CP and the derivative-RS, the prefixes tetra, penta, etc. only indicate the average degrees of esterification

or etherification. The compounds exist as a mixture of materials ranging from the monoester to the fully esterified ester. What is referred to in this document is the average degree of esterification as determined by weight.

The derivative-CP and the derivative-RS that are used do not have a substantial crystalline character at 20 ° C. Instead, they are preferably in a liquid or soft solid state, as defined below, at 20 ° C.

The cyclic polyol or reduced saccharide starting material is esterified or etherified with C8-C22 alkyl or alkenyl chains to the appropriate degree of esterification or etherification so that the derivatives are in the required liquid or solid solid state. These chains may contain unsaturation, branching or mixed chain lengths.

Typically, the CP-derivative or the RS-derivative has 3 or more, preferably 4 or more, for example 3 to 8, for example 3 to 5, ester or ether groups or mixtures thereof. It is preferred that two or more of the ester or ether groups of the derivative-CP and

The derivative-RS is independently linked from one another to a C8 to C22 alkyl or alkenyl chain. The alkyl or alkenyl groups can be branched or linear carbon chains.

CP derivatives are preferred for use as a fatty sugar derivative. Inositol is a preferred cyclic polyol, and inositol derivatives are especially preferred.

In the context of the present invention, the terms derivative-CP and derivative-RS encompass all ether or ester derivatives of all forms of saccharides, which fall within the definition, and are especially preferred for use. Examples of preferred saccharides so that the CP-derivative and the RS-derivative are derived from them are monosaccharides and disaccharides.

Examples of monosaccharides include xylose, arabinose, galactose, fructose, sorbose and glucose. Glucose is especially preferred. An example of a reduced saccharide is sorbitan. Examples of disaccharides include maltose, lactose, cellobiose and sucrose. Sucrose is especially preferred.

If the derivative-CP is based on a disaccharide, it is preferred that the disaccharide has 3 or more ester or ether groups attached to it. Examples include tri, tetra and penta esters of sucrose.

5 When the cyclic polyol is a reducing sugar, it is advantageous that each ring of the CP derivative has an ether group, preferably in the C1 position. Suitable examples of compounds of this type include methyl glucose derivatives.

Examples of suitable CP derivatives include alkyl (poly) glycoside esters, in particular alkyl glycoside esters having a degree of polymerization of 1 to 2.

The HLB of the CP-derivative and the RS-derivative are typically between 1 and 3.

The CP-derivative and the RS-derivative can have branched or linear alkyl or alkenyl chains (of varying degrees of

15 branching), mixed chain lengths and / or unsaturation. Those having unsaturated and / or mixed alkyl chain lengths are preferred.

One or more of the alkyl or alkenyl chains (independently attached to the ester or ether groups) may contain at least one unsaturated bond.

For example, predominantly unsaturated fatty chains can be attached to the ester / ether groups, for example, those that are linked can be derived from rapeseed oil, cottonseed oil, soy bean oil, oleic fatty acids, tallow , palmitoleic, linoleic, erucic or other sources of unsaturated vegetables. The alkyl and alkenyl chains of the CP-derivative and the RS-derivative are preferably predominantly unsaturated, for example,

As mentioned above, unsaturation can help photoreaction fragmentation of molecules into more hydrophilic components. In this context the softener plays the dual role of smoothing and HH material.

As a primary softener some CP-derivatives and RS-derivatives may be based on alkyl or alkenyl chains derived from polyunsaturated fatty acid sources, for example, sucrose tetralinoleate. It is preferred that most, if not all, of the polyunsaturation has been removed by partial hydrogenation if polyunsaturated fatty acid chains of this type are used.

The highly preferred liquid derivatives-CP and RS-derivatives are any of those mentioned in the three preceding paragraphs but in which polyunsaturation has been eliminated by partial hydrogenation. However, as with HH material, polyunsaturation with linoleic fatty acids limited to <10% is acceptable.

Especially good smoothing results are obtained when the alkyl and / or alkenyl chains of the CP-derivatives and RS-derivatives are obtained using a mixture of fatty acids (so that they react with the cyclic polyol or reduced starting saccharide) comprising a mixture of tallow fatty acid and oily fatty acid with a weight ratio of 10:90 to 90:10, more preferably 25:75 to 75:25, most preferably 30:70 to 70:30. A mixture of fatty acids comprising a mixture of tallow fatty acid and oily fatty acid with a weight ratio of 60:40 to 40:60 is most preferred.

Especially preferred are mixtures of fatty acids that comprise them in a weight ratio of about 50% by weight of tallow chains and 50% by weight of oil chains. It is especially preferred that the mixture of fatty acids consists only of a mixture of tallow fatty acid and fatty acid of

55 oil.

Preferably 40% or more of the chains contain an unsaturated bond, more preferably 50% or more, most preferably 60% or more for example 65% to 95%.

Other fatty sugar derivatives suitable for use in the compositions include sucrose pentalaurate, sucrose pentaerucate and sucrose tetraerucate. Suitable materials include some of the Ryoto series available from Mitsubishi Kagaku Foods Corporation.

Another class of suitable sugar fatty derivatives are those described in the recent WO document

65 2006/076952 (A1) of the present authors such as Emanon SCR-PK (from KAO), which is an SPE (sugar polyester) derived from palm kernel oil containing mainly C12-C14 with approximately 20% monounsaturation of C18 and SPE-THSBO (from Clariant), which is derived from somewhat hardened soy bean oil, which mainly has C16-C18 chains with approximately 80% mono and di unsaturation. The average degree of esterification of the above preferred SPEs is between 4.2-4.7.

5 The CP-derivatives and RS-derivatives liquid or soft solids are characterized as materials having a solid: liquid ratio between 50:50 and 0: 100 at 20 ° C as determined by the relaxation time T2 of NMR, preferably between 43: 57 and 0: 100, most preferably between 40:60 and 0: 100, such as 20:80 and 0: 100. The relaxation time T2 of NMR is commonly used to characterize the solid: liquid relationships in soft solid products such as fats and margarines. For the purpose of the present invention, any component of the NMR signal with a T2 of less

10 out of 100 microseconds is considered to be a solid component and any component with T2 greater than 100 microseconds is considered to be a liquid component.

The derivative-CPE and the derivative-RSE can be prepared by various methods well known to those skilled in the art. These methods include acylation of the cyclic polyol or a reduced saccharide with an acid chloride;

Transesterification of the cyclic polyol or a reduced saccharide material with esters of short chain fatty acids in the presence of a basic catalyst (for example KOH); acylation of the cyclic polyol or of a reduced saccharide with an acid anhydride, and, acylation of the cyclic polyol or of a reduced saccharide with a fatty acid. Typical preparations of these materials are described in US 4386213 and AU 14416/88 (Procter and Gamble).

When a fatty sugar derivative is present, the compositions preferably comprise between 0.5% -30% by weight of the fatty sugar derivatives, more preferably 1-20% by weight, most preferably 1.5-20% by weight. weight, for example 3-15% by weight, based on the total weight of the composition.

Arquad 2HT is a hardened dimethyl ammonium di-tallow chloride. 30 Procedure

Treatment

35 Polyester or clean cotton samples were cut into 20 cm x 20 cm pieces. Two pieces of such monitors were placed in a Tergotometer with 1 liter of tap water to which 0.48 g of the compositions in set 1 had been added and stirred for 15 minutes. A monitor was then removed and 0.01 g of Acid Red 51 photosensitizer (AR51) was added and stirred for another 15 minutes before removing it from the Tergotometer. Textile monitors were then centrifuged for 1 minute in the centrifugal dryer.

40 This procedure provided 0.16 μg of AR51 / g of textile material and 8 mg of textile material conditioner / g of textile material.

The treated textile monitors were allowed to dry on the clothesline in a drying room overnight (in dim fluorescent light during the day but in the dark at night).

Light exposure

Next, the dry treated monitors were cut into 15 cm x 7 cm rectangles and placed in the 50 support frames of the Weatherometer Atlas ready for light exposure.

Samples of textile materials were then exposed to a 2 kw xenon light source for 30 minutes with a relative humidity between 50-60%, at the beginning of the test that reached 20% RH at the end of the 30 minute period .

Once the exposure was carried out, the monitors were evaluated for their wetting behavior on the exposed side and (Front) and reverse side (Reverse). 5 Wet test

Exposed and unexposed samples were evaluated for wetting by placing several 50 mg drops on the surface of the textile material and recording the time it took for the drops to completely penetrate the surface. This was carried out on both sides of the exposed monitors.

Results

600+ wet time means more than 10 minutes. In the previous cases really more than 30 minutes. A wetting time of> 10 minutes represents a fairly hydrophobic surface.

It will be seen from examples 4 and 4 + AR 51, squalene oil with eight double bonds in the molecule, which confers greater hydrophobia on the reverse side of the fabric than on the front of the fabric in the presence of photobleach, which translates into greater comfort due to moisture transport of the skin.

25 Cotton knitted under a similar treatment remained hydrophilic in all treatments.
