Cosmetics packaging lipstick tube method of acceptance

Lipstick is the floorboard of all lip colour makeup. Lipstick including lipstick, lip stick, lip gloss, lip glaze, etc. , can make the lips ruddy luster, to moisturize, protect lips, facial beauty and amended lip contour have foil effect of a product, and for the lipstick lipstick tube packaging products be forgotten, because of complex structure and function, and quality is also more difficult to handle. Therefore, cosmetics packaging lipstick tube quality request is higher, at the time of acceptance of the lipstick tube need to do the following methods:

a, specification test

1, the instruments and equipment: electronic balance, 0. 01 g) , plastic board, vernier calipers.

2, weight requirements: with a sense of volume of 0. 1 g of weighing apparatus according to atc, within the scope of the standard values and tolerances of the two sides confirmed ( ±0. 2 g) 。

3, size requirements: using precision measuring instruments, the length of the lipstick tube, pipe diameter, aperture, sealing length, tube wall in the range of values and tolerances of the two sides confirmed.

4, full capacity: the sample tube and plastic board is put in the middle of the electronic balance to zero; Within the atc feed to full body, after cooling to fill material to the nozzle, with blades scrape the nozzle body, excess weight.

2, size and sex of detecting

use vernier caliper to measure, each batch of material of each model number of tube, cap, plug in at least 10 each, different mode of tube, cap, plug to form a complete set of random number. Will form a complete set of good lipstick tube matching blister, check its supporting conditions. With good cover, measured with vernier caliper is broken.

3, precession, or launch

inspection methods: precession or launched more than 500 times.

4, rigor test

1, the inspection method: horizontal pendulum, a handstand in 45 ℃ constant temperature box 24 hours without oil leakage.

2, vacuum leak test ( Limited have air tightness requirements of products) : the product filled with water, put in vacuum box lay ( Or inverted) In the paper, white water imbibition vacuum - 0. 08 mpa, 15 minutes, loss rate shall not be greater than zero. 5%.

5, drop performance test

inspection methods: tube with the same as the product of net content of material with the corresponding body cover, from the ground 76 cm to 1 m, the level of exhaust, free fall to the ground; The same sample fell three times.

6, solvent resistant test

1, the inspection method: smear with corresponding paste on the printing test, put in 45 ℃ constant temperature box after 24 hours with rubbing alcohol wet gauze conventional disinfection method is wiped clean, observation for the peeling coating; If the corresponding pipe, cover in using other solvents to wipe or leaching pretreatment process, the result according to the resistance to solvent pretreatment method accordingly, after 24 hours of observations.

2, testing frequency, for the production of products, with the specification of the same type mouth red envelope material testing at least once a month; For new product packaging must test for the first time.

7, red mouth materials and contents compatibility

test method: lipstick tube after filling and good material body according to the production process, vertical pipe shaft completely launch material body whirl again, repeat 3 times smooth operation, paste without falls off phenomenon.

8, the total number of colonies test

1, sampling: with sterile saline 3 ml, cover, at the bottom of the top lid and oscillation, many times make a good contact with physiological saline packaging tube wall.

2, calculation formula: colony count ( CFU/pipe) = the average number of colonies/sampling quantity x per tube with water.

3, frequency of testing: different suppliers with kind and the mouth of the red envelope material testing at least once a month, on the mouth of the unqualified bonus material for subsequent three continuous detection.
