How Cobalt Blue glass functions as a filter for volatile botanical compounds and active dermaceuticals.
Unlike clear or green glass containers, Cobalt Blue Glass utilizes transition metal oxides within the silicate matrix to filter specific wavelengths of electromagnetic radiation. The chemical integration of cobalt oxide (CoO) creates a highly specific absorption band. This filtration shields compounds from UV-A and UV-B radiation (290nm to 400nm) while transmitting stable blue light frequencies. This is crucial for protecting premium formulations that are highly vulnerable to photo-oxidation, preserving active ingredients for extended shelf-lives.
Lecos Glass containers are produced using advanced medical-grade soda-lime silica and Type I borosilicate compositions. This ensures our blue glass dropper bottles achieve high hydrolytic resistance ratings conforming to USP <660> and EP 3.2.1 standards. By reducing alkali leaching, we prevent chemical degradation of cosmetic liquids, maintaining formulation integrity and product safety over time.
Lecos Glass has been dedicated to the glass packaging industry for over 10 years with our innovative wholesale glass bottles and jars for cosmetics, perfume, personal care, essential oils and candle jar glass packaging. We pride ourselves in offering bespoke glass bottles to our global clientele.
Basically, we have a large range of glass bottles, jars, and accessories you'll ever need. Although we feature hundreds of distinct molds, our collections primarily include:
Lecospack provides professional glass cosmetic packaging solutions to worldwide customers. With years of experience in the field, we are capable of providing innovative, stable quality and cost-effective packaging according to our customers' DNA.
The quality of our glass products is strictly controlled, winning the favor of both domestic and foreign cosmetic brands. We work with many global beauty houses directly and indirectly. We also offer all kinds of customized deep processing for glass bottles, such as:
Rigorous raw material selection and multi-stage optoelectronic checking lines.
Cost optimization through lean production runs and supply chain integration.
24/7 client communication, expert customs handling, and active post-sales support.
Leveraging specialized industrial clusters, raw material purity, and advanced mechanical tooling.
Our facility is situated in the heart of China's glass manufacturing province, giving us direct access to high-purity silica sand, sodium carbonate, and natural gas infrastructure. This lowers transit and raw material costs.
We maintain in-house tool and die design centers. While Western factories require 8-12 weeks for a custom sample mold, our CNC tooling centers can deliver physical glass mockups in under 20 days.
Equipped with individual section (IS) machinery, our lines operate continuously. Automated optoelectronic systems check for micro-cracks, neck dimensions, and cosmetic bubbles on the line.
Our company is built on a solid foundation of deeply held values that set us apart, steer our actions, and infuse every aspect of our corporate culture. These values are not just words; they are the principles that guide how we operate daily.
Central to our business practices are our unwavering commitment to social responsibility, adherence to ethical standards, and steadfast support for universal human rights. We are also dedicated to protecting the environment and making a positive impact in the communities where we live and work.

By upholding these values, we ensure that our company remains a responsible, ethical, and inspiring place to work.
Evaluating packaging design demands and product life cycle considerations.
As clean beauty labels expand globally, brands require packaging options that contain no synthetic plasticizers, heavy metals, or toxic chemical coatings. Pure blue glass acts as an inert container, eliminating the risk of compound leaching.
Post-Consumer Recycled (PCR) glass integrations are becoming a key brand requirement. We offer custom glass batches integrating up to 45% PCR content, significantly reducing carbon footprint during the melting phase.
High concentrations of organic terpenes can interact with and degrade lower-grade plastics, leading to bottle distortion or product spoilage. Heavy-walled cobalt blue glass provides a stable, impermeable barrier for volatile oils.
Lecos Glass integrates specialized closure assemblies including silicone, NBR, and TPE bulbs paired with low-borosilicate glass pipettes to deliver precise drop volumes (e.g., 0.5ml or 1.0ml) for exact dosage.
Aesthetic, high-durability containers designed to meet global beauty standards.
Empowering luxury skincare, essential oil providers, and pharmaceutical brands worldwide.
