Examples

The following examples were carried out as follows:

the parameters fixed are as follows:

-mixing conditions, power and mixing time;

-the conditions of the bottle;

-spray conditions, spray volume, spray tool conditions;

-the amount of diluted water used for the coating solution;

-storage conditions.

More precisely:

concentration of formulation in aqueous coating solution (wt%): 5.0-7.5;

hardness of water: 3 ℃ DH;

-bottle temperature: 20 ℃;

-spray amount per bottle: 0.5mL per vial (upper fray zone only);

-storage conditions: room temperature, 1 hour;

-a mixing device:this was continued for 5 minutes at 20% stirring power.

The following conditions were used to apply the various formulations:

-spray gun (application gun): air-guided spray coating (P)_{Guiding air}2 bar, P_{Spraying of paint}1.5 bar);

-spray pattern: horizontal;

-spray volume: 0.5mL, directed only at the shoulder wear zone;

-bottle rotation: plus or minus 30 rpm;

-bottle type: coca25cL；

-number of bottles: 5 pieces of the Chinese herbal medicines.

1) Improved properties of the compositions of the invention

-the compositions tested were:

-composition a:140

composition 1 (according to the invention): 84% by weight of Blankol XT, 15% by weight of Surfaline SE-81 and 1% by weight of water

A. coating Properties

At 24 hours after application, the bottles were inspected for scratch masking efficacy by visually observing the shoulder abrasion bands of the bottles. For each vial, a label from 0 to 5 is given:

for masking efficiency, "0" means no coating and "5" means 100% masked;

for the tactile experience, "0" means a greasy appearance with visible droplets and "5" means instructing a pleasant glassy appearance.

The results are the sum of the markings obtained from the 3 coated bottles and are shown in table 1 below.

TABLE 1

These results show that the compositions of the present invention provide better masking than commercially available compositions and, in addition, improve the tactile experience (especially reducing the likelihood of a greasy touch when applied in excess (chance)).

Label sensitivity:

will be provided withThe BEER label was placed between filter papers and saturated with 10 wt.% of composition a and 1. The wet label placed between the filter papers was held between the two glass sheets for 24 hours.

For each vial, a label from 0 to 5 is given:

for smear, "5" means no smear and "0" means high smear;

for ghosting (ghost), "5" means no ghost impression and "0" means a strong ghost impression.

The results are set forth in Table 2 below:

TABLE 2

Formulations	Wiping dirty	Double images	Sigma score
				Composition A	3	0	3
Composition 1	5	3	8

2) Stabilization Using Blandol XT

The following compositions were prepared as described above and tested for their stability at room temperature, 40 ℃ and 0 ℃.

The results are shown in tables 3 and 4 below.

TABLE 3

TABLE 4

These results show that the compositions of the present invention do not exhibit phase separation at room temperature conditions, 40 ℃ and 0 ℃.

3) Stability with other oils

The same experiment was repeated with other oils:

a composition comprising 85 wt% oil, 15 wt% SURFALINE SE81 and 1% water was prepared as previously described.

The following oils were tested:

TABLE 5

Suppliers of goods	Trade name	Viscosity (mPa.s) at 20 DEG C
			SIP	SIPMED 20	44
Shell	Catenex T121	42
				Risella X45	15
Petro Canada	Puretol 11D Bulk	42
				Purity 1020 base oil	47
Sonneborn	Parol	170

No separation was observed at room temperature conditions, 0 ℃ and 40 ℃ except for the Parol oil, which had a viscosity of 170mpa.s, in the case of the Parol oil, phase separation was observed for all these temperatures.

4) Composition comprising hydrogen peroxide

Examples 1 and 2 were reproduced, however, in compositions 1 to 8, hydrogen peroxide was used instead of water. Results similar to those of examples 1 and 2 were obtained.
