Description

Fabric rinse composition containing a cationic UV absorber

The present invention relates to a fabric cleaning composition containing a UV absorber and to a method of treating textiles with the composition to impart other desirable properties in addition to good UV cut index (UPF) to the treated textile fiber material. .

Light radiation with a wavelength of 280-400 nm is known to tan the epidermis. Light rays with a wavelength of 280 to 320 nm (called UV-B radiation) are also known to cause redness and skin burns and to inhibit skin tanning.

Radiation of wavelength 320-400 nm (called UV-A radiation) can induce skin tanning, but it is known to cause skin damage, especially to sensitive skin, when exposed to sunlight for a long time. Examples of such skin damage include loss of skin elasticity and wrinkles, promotion of initiation of the redness reaction, and induction of phototoxic or photoallergic reactions.

In order to effectively protect the skin from the damaging effects of excessive exposure to sunlight, a means is needed to absorb both the UV-A and UV-B components of sunlight before reaching the skin surface.

Conventionally, protecting human skin exposed to potential damage by UV components in the sun has been done by applying a formulation containing a UV absorber directly to the skin.

One aspect of the desire to increase the level of skin protection against sunlight has been to consider additional methods that go beyond the method of directly protecting the skin. For example, methods have been considered to protect the skin from clothing and being exposed to direct sunlight.

Most natural and synthetic textile materials are at least partially transparent to the UV component of sunlight. Thus, simply dressing does not necessarily provide adequate protection against damage by UV radiation to the skin under the clothes. Although clothes containing deeply colored dyes and / or tightly woven tissue protect the skin beneath it to an appropriate level, such clothes are not practical in hot sunny climates in terms of wearer's physical comfort.

Thus, there is a need to provide UV radiation protection to the skin underneath the garment, including lightweight summer garments that are not dyed or dyed only in light tones. Depending on the dye properties, the skin under the clothes dyed in some dark tones may also require UV radiation protection.

Such lightweight summer clothes usually have a density of less than 200 g / m ² and a sun protection index of 1.5 to 20, depending on the type of fiber from which the clothes are made.

The UPF rating of sunscreen (sun cream or clothing) can be defined as a multiple of the time it takes for a person wearing sunscreen to undergo a sun burn under normal exposure to sunlight. For example, if the public experiences a turnover after 30 minutes under standard exposure conditions, a sunscreen with a UPF rating of 5 extends the blocking period from 30 minutes to 2 hours 30 minutes. The UPF rating is about 20 for people with minimal average turnaround time, for example, those who live in a daylight, especially when there is only 15 minutes of turnaround time at the hottest hour of the day for an average white-skinned person. Lightweight clothes are needed.

When selecting a suitable UV absorber (UVA) for use in a method of increasing the UPF value of a textile fiber material (sometimes referred to as a "UV cutting" treatment), the treated textile fiber material can be used in a wide range of conditions apart from its UPF value. Consideration should be given to the performance criteria for areas such as washfastness, lightfastness and tear resistance.

Another major problem for most consumers in the world is fading due to sunlight of colored fabrics during wearing and during drying (so-called “light fading”). Thus, sensitive fabrics can be discolored severely at high latitude temperatures other than the tropics. Light discoloration of the fabric is of particular interest to consumers because the contrast between exposed and unexposed areas makes this particularly pronounced.

Surprisingly, it has been found that the use of certain UV absorbers in fabric cleaning compositions effectively improves the UPF, while effectively preventing light fading of the fabric.

Accordingly, the present invention is based on the total weight of the composition, 0.1 to 10% by weight, preferably 0.1 to 5% by weight of the UV absorber (a) of Formula 1, 5 to 25% by weight of the fabric softener (b) and water ( providing a stable concentrated fabric cleaning composition comprising c).
