Description

Technical Field

[0001] The present disclosure relates to the technical field of cosmetics testing, and in particular to a sand resistance testing device for sunscreen products. Background Art

[0002] UVB rays, with a wavelength of 280 to 320 nm, can cause skin darkening and are the main cause of sunburn. UVA rays, with a wavelength of 320 to 400 nm, can tan the skin, cause sun spots, and contribute to photoaging. Without or insufficient sun protection, signs of photodamage can gradually become apparent over time, such as freckles, age spots, and wrinkles, and can even lead to precancerous skin growths, skin cancer, or both.

[0003] The skin of infants and young children is not fully developed, the barrier function is weak, the skin structure is quite different from that of adults, and the skin is more sensitive. After being stimulated by external stimuli, it is easy to cause a series of skin discomfort symptoms such as redness, dryness, roughness, and peeling. In daily life, we need to pay attention to and strengthen care, such as daily moisturizing and applying sunscreen products when going out.

[0004] While current research on the sun protection capabilities of sunscreen products focuses on factors such as SPF and usage, the integrity of the film also impacts the product's performance. Ultraviolet rays are intense at the seaside, so parents often use sunscreen on their children. Children also enjoy playing on the beach, where they are active and subject to significant friction and collision with sand. These activities can affect the integrity of the film, and thus its effectiveness. However, current sunscreen products rarely undergo testing specifically for this scenario.

[0005] CN117470746 A discloses a method for rapid visual inspection of the sunscreen effectiveness of sunscreen products and its application. It explores methods for testing the sand and friction resistance of sunscreen products, filling a gap in the field of friction and sand resistance for sunscreen products. However, this proposal focuses on developing a visual method for in vitro sand and friction resistance and characterizing the sand resistance strength of sunscreen products, without examining a device for testing human sand resistance.

The box body 1 is also provided with an air blowing port 10. The air blowing device blows air to the sand-receiving part 7 through the air blowing port 10, blowing the sand particles into contact with the subject's arm.

[0037] In a preferred embodiment, the test port 8 includes a test hole 81, which is connected to a sand-proof cover 82 for preventing the sand from splashing out of the box 1. The subject's arm passes through the sand-proof cover 82 and extends into the box 1. The sand-proof cover 82 is made of natural or synthetic rubber.

[0038] For example, the diameter of the test port 8 is set to 10-15 cm. When the subject is a female or has thin arms, the diameter of the test port 8 is preferably set to 10 cm; when the subject is a male or has thick arms, the diameter of the test port 8 can be increased according to actual conditions. Figure 5 As shown, the sand-proof cover 82 is fixed to the test hole 81 by a circular buckle 83. The diameter of the sand-proof cover 82 gradually decreases from the test port 8 toward its end to 8 to 13 cm, preferably 8 cm.

[0046] Rotate the support leg relative to the fixed frame 23 and prop up the support leg, and adjust the adjustment buckle 21 of the telescopic rod until the support leg is at the appropriate measurement height. Open the box cover 3, install the sand-proof net 71 and the square hoop buckle 73 on the sand-bearing plate 72, and pour a certain amount of ISO standard sand. Install the wind speed measuring instrument on the buckle 62 of the support rod 6, rotate the rotating part 61 to adjust the measurement direction, close the box cover 3 and buckle 5. Mark the test area on the inside of the subject's forearm and apply sunscreen product.
