Embodiment 1

[0141] Table 1. Detergent formulations

[0142] The samples contained either 0.2% UV absorber (Uvinal MS-40) or 0.11% fluoresor dye. Control samples did not contain this protectant. The results are as follows (Table 2):

[0143] sample

[0144] In UV-A / B room (UVA=1.01mW / cm 2 , UVB=6.17μW / cm 2 A similar experiment was carried out under the light). HDL containing enzymes and protectants were exposed to UV light for 4 days. The results are as follows (Table 3):

[0145] sample

[0146] Tables 2 and 3 above demonstrate that the presence of either UV absorber or f-dye increases the stability of both protease and lipase under UV light, as shown as a percentage of residual activity.

Abstract

An enzyme containing translucent or transparent aqueous heavy duty liquid in a clear bottle comprising fluorescent dye and / or UV absorber.

Description

field of invention [0001] The present invention relates to an enzyme-containing aqueous transparent or translucent high-efficiency liquid laundry detergent in a transparent or translucent bottle, which includes fluorescent dyes (f-dye) and / or UV absorbers. The f-dye and / or UV absorber protects the enzyme present in the HDL composition from harmful UV radiation, thereby preserving the enzyme activity. Background of the invention [0002] Liquid detergents are usually sold in opaque bottles. However, the use of a transparent bottle can provide consumers with aesthetic satisfaction as they can see the consistency of the product as well as suspended particles, if present. But the use of transparent bottles may lead to undesired loss of enzyme activity (ie enzymes present in the liquid composition) caused by UV rays. Ultraviolet light refers to light having a wavelength of about 250 to about 460 nanometers (nm). Specifically, UVA is generally in the range of 320-400nm, UVB is ...
