Description

Detergent composition

The present invention relates to a detergent composition, and more particularly to a detergent composition to which sodium hydrogencarbonate and natural essential oils are added.

In the case of conventional laundry detergents, they are added and used during the textile washing process to remove dirt, dirt and stains from the surface of the textile. Laundry detergents can be divided into liquid and powder forms. In general, the blends are composed of anionic and nonionic surfactant components, which can be increased in any proportion as needed to improve the cleaning effect. Typically, laundry detergents add flavors that function to give the washed textiles an aromatic scent. However, perfume compounds have a high degree of volatile substances and need to remain stable to prevent them from evaporating quickly. During the laundry process, the volatile components of the essence should continue to maintain aroma, not only throughout the laundry process, but also on the textile after the drying process. The technology of fragrances for detergents has been quite developed, for example, various petroleum additives can be added to the fragrance compounds to slow the evaporation rate of the fragrance. Alternatively, the fragrance can be stored in a carrier material, encapsulated or embedded in a compound to achieve controlled release. Fragrance and petroleum additives need to exist at the same time. If there is no petroleum additive, the fragrance will disappear after washing. In general, perfume is not considered to be an active ingredient, which primarily transfers aromatic odors to the washed textile during the washing process.

Recently, in an atmosphere that emphasizes environmental protection and human health awareness, there has been a major focus on laundry detergents, which emphasizes that laundry detergent ingredients are natural and environmentally friendly. Many environmental groups believe that flavors are an unnecessary and unhealthy ingredient in detergents, because the petroleum additives needed to prevent the evaporation of flavors are not degradable and are considered unhealthy, especially for clothing and people. There is direct contact with the skin. Therefore, there is a continuing development that the use of natural raw materials not only washes clothes, but also has a low environmental hazard.

Example 2: Detergency test:

Cleaner cleaning test, using standard stains Cotton 100, PC14 as cleaning object, Cotton 100 is 100% cotton, which contains ink, oil, soy sauce, juice, tea, coffee, simulating common common dirt. The test method pours the detergent into the washing tank. The water source uses a hardness of 250 ppm and the detergent usage is 24 g/36 liter. Before performing the cleaning, the whiteness meter was used to measure the whiteness value of the contaminated cloth. After the standard laundry procedure, the same whiteness test was performed using a whiteness meter. The whiteness change caused by the cleaning of the standard stained cloth is used as the cleaning power of the cleaning agent. The greater the change in the whiteness value, the stronger the cleaning power of the cleaning agent.

Comparison of detergent composition of the present invention with commercially available brand laundry detergent

The detergent composition of the present invention JB-1, JB-2, JB-3, JB-4, JB-5, JB-6 and JB-7 and a commercially available brand laundry detergent (competition), Cotton for different pollution sources The 100 soiled cloth was subjected to the above-described detergent cleaning power test.

The test results are shown in Figures 1 to 6, which respectively show the detergent and competing products of the present invention, and wash different pollution sources at 25 ° C and water hardness of 250 ppm (the first to sixth figures are soy sauce, juice, ink, and motor oil respectively). , tea, coffee) Contaminated cloth on Cotton 100, the results measured using a whiteness meter. The basic composition of JB-1~JB-7 is roughly the same, including the inclusion of surfactant (sodium linear alkylbenzene sulfonate (LAS), fatty alcohol ethoxylate, polyoxyethylene alkyl ether sulfate (SLES). Mixture), hard water softener (mixture of sodium carbonate, sodium citrate and zeolite 4A), anti-precipitant (sodium carboxymethylcellulose), other additives (fragrance, enzyme, fluorescent agent, antibacterial agent) and specific ratio The main difference is the addition of baking soda and essential oils. For example, JB-2~JB-7 contain different proportions of baking soda (3% or 9%), or eucalyptus essential oil (JB-3). And JB-7) or tea tree essential oils (JB-4 and JB-6), etc., as a comparison of whether these ingredients affect the washing effect.

The results of the respective figures show that the detergent composition of the present invention can enhance the detergency performance after adding tea tree oil or eucalyptus essential oil, for example, a detergent added with baking soda (JB-2~JB-7). The overall performance is better than the cleaning agent (JB-1) without baking soda. Increasing the proportion of baking soda (compared to JB-2 and JB-5) can also improve the overall detergency, although the results show that the addition of essential oils seems to affect the washing effect slightly (compared to JB-2~JB-4 and JB). -5~JB-7), however, compared to the control group or competing products without added baking soda, the washing effect is still quite excellent, and the natural essential oil added with tea tree oil or eucalyptus essential oil is effective. In other words, it can increase the antibacterial and anti-caries properties of the laundry, and can reduce the occurrence of skin allergies or asthma.

Although the results of the various figures show that the detergent composition of the present invention has different washing powers for different sources of pollution, the sources of contamination which are generally difficult to clean, such as ink or oil, have a relatively good cleaning effect. In summary, it can be more clearly shown from the display results that the detergent composition according to the present invention has superior detergency for various stains, and the natural essential oil of tea tree oil or eucalyptus oil can be added to increase the washing clothes. Antibacterial and anti-mite properties.
