Liquid Distributor-HY18A-11

Antioxidant protection cosmetic pump head Liquid Distributor-HY18A-11 is a core component of high-end cosmetic packaging, designed for skin care products containing easily oxidized active ingredients. This type of pump head reduces the inactivation of ingredients and prolongs the product's efficacy life by isolating air and ultraviolet rays. With the rapid growth of the functional skin care market (CAGR of over 15%), the demand for antioxidant packaging has increased significantly, and precision dispensers such as HY18A-11 have become standard for essence lotion products.

The core function of Antioxidant protection cosmetic pump head Liquid Distributor-HY18A-11 is to achieve long-term stability of the contents through physical barriers and material innovation. The pump head usually adopts a spring return seal structure with high-precision ceramic or glass bearings to reduce the contact between metal parts and formulas. At the same time, the built-in nitrogen replacement mechanism can discharge the air in the bottle after each press to reduce the risk of oxidation. Some high-end models use amber or opaque composite materials to make the pump body to further block the damage of ultraviolet rays to active ingredients.
The HY18A-11 pump head uses medically certified PP as the main material, and its chemical inertness can prevent reactions with active ingredients. Key seals are mostly made of silicone or PTFE, which can not only ensure the pressing life, but also maintain dosage accuracy, which is particularly important for the precise dosing of expensive antioxidant essences. The design of the liquid outlet is improved through atomization technology, so that high-viscosity antioxidant solutions can also form a uniform mist distribution.
This category of pump heads has passed cosmetic certification to prevent packaging materials from contaminating highly active formulas. It is worth noting that this type of pump head often needs to be used in conjunction with a double-layer barrier bottle (such as HDPE/EVOH composite bottle) to build a complete anti-oxidation barrier system.

The HY18A-11 pump head is mainly suitable for 30-50ml essence products. Its slender pump nozzle design can accurately control the single dosage in the range of 0.3-0.5ml, which is particularly suitable for repair ampoule products.
Antioxidant protection cosmetic pump head Liquid Distributor-HY18A-11 has become an indispensable key component of high-end antioxidant skin care products with its sophisticated design and strict material standards. It not only effectively extends the shelf life of active ingredients through innovative sealing technology and UV blocking design, but also improves user experience with precise dosage control and stable performance.
