Description

[0001] Solid laundry soap compositions for baby garments or undergarments [

More particularly, the present invention relates to a solid laundry soap, and more particularly, to a soap composition comprising a vegetable natural soap base, a coconut fatty acid-derived betaine, an ethylene oxide addition fatty alcohol nonionic component (a natural alcohol ethylene oxide addition nonionic surfactant) The present invention relates to a solid laundry soap for infant clothes or underwear having high contact with the skin by containing polyglucoside and plant extract.

Generally, according to Korean Industrial Standard (KS), the solid laundry soap is divided into a commodity, a souvenir, and a souvenir, and a washing auxiliary agent of 13 to 23% by weight is used for the washing soap of the commodity. As such auxiliary agents, inorganic salts, alkali salts, carbonates, phosphates, silicates and the like are used to contribute to the improvement of the cleaning ability.

In essence, the soap itself is less detergent than synthetic detergent but has high biodegradability and low skin irritation.

One of the reasons for the low cleaning power of soap is the effect of bivalent metal ions such as calcium and magnesium contained in water. The synthetic detergent acts on the divalent metal components contained in the water and is dispersed without being precipitated and removed during rinsing. However, in the case of soap, it forms a soap scum, which is not dissolved in water and adhered to wash basin, laundry container, So that it acts as another contamination and deteriorates the cleaning ability. In order to compensate for the deterioration of the detergent, the solid soap for washing has a strong alkaline environment by adding carbonate, phosphate and silicate, thereby enhancing the detergency.

On the other hand, the contamination source of garments has a lot of oil components such as sweat and lipid generated from the external dust and the body, so that it is re-saponified during washing in the alkaline environment, thereby enhancing the washing power. However, at the same time, the use of such strong alkali salts causes damage to laundry clothes and skin irritation, and adversely affects environmental pollution. Therefore, consumers tend to avoid environmental problems and skin irritation problems.

Accordingly, development of a detergent suitable for clothes washing or general underwear washing of an infant sensitive to skin is desired.
