The scrub bead is a gel with beetroot pulp held inside it
1 / 8
The fullest process description is in an Indian academic filing. Beetroot paste is mixed with 6% sodium alginate at a 2:1 ratio, dropped into a chilled 3% calcium chloride bath, washed in distilled water and dried at 60 °C for 20 minutes. The calcium ions crosslink the alginate, so the skeleton of the particle is a hydrogel and the pulp supplies the abrasion, the colour and the antioxidants, including vitamin C, betalains and polyphenols.
The only on-pack microplastics statement the law requires is a warning
2 / 8
Lip, nail and make-up products carry the longest transition of any category, and they alone get a labelling duty inside it: from 17 October 2031 such products must state on the pack that they contain microplastics to remain on the market, four years before the restriction reaches them in 2035.
Strategy
The near-term supply comes from a company that already owns the plant
3 / 8
Eastman put Esmeri SK1N10 on the market in October 2026 for skin care and sun care, a grade added to a cellulose chemistry business it describes as more than a century old. That is a product a formulator can buy now. The venture-funded capacity is not. Bioweg starts construction in the fourth quarter of 2026 with 10,000 tonnes planned for 2028, Cellugy's €8.1 million was raised to scale a thickener, and Naturbeads was running a small-scale facility as of March 2026.
Research
Chilling the calcium bath sets how hard the bead is
4 / 8
Calcium-alginate beads stiffen with more alginate and more calcium, and they stiffen again when the bath is colder. Beads gelled at 5 °C reached the highest rupture strength in a controlled study, because slow calcium diffusion gives a more even internal network. Strength also rises with alginate concentration, and drying stiffens a gel bead further as water leaves it. Read against that work, the chilled bath and the 60 °C drying step in the patent are the two settings that fix bead hardness. My inference is that both will need retuning as the solids in the pulp change from batch to batch.
Market
The advisory layer is circulating dates that are wrong
5 / 8
A European compliance consultancy's own page states that the first cosmetic deadline passed in October 2025 and that rinse-off products containing microbeads should have left the EU market after 17 October 2025. Microbeads came out in 2023 and rinse-off follows in 2027. The same publisher runs another page correctly framed around the 2027 deadline, which makes the error a property of the content layer rather than a position anyone holds.
Strategy
The brand-side work has moved to the contract manufacturers
6 / 8
The clearest account of a brand-scale reformulation in this material does not come from a brand. Hardford, a Swedish contract manufacturer, ran a project that sent more than thirty formulations through SPF and water-resistance testing, removed the microplastic polymer and kept water resistance, and is continuing to refine the sensory profile. Its interviewee says customers are asking for removal now rather than waiting for a date.
Research
A natural wax can take over the structurant job in a stick
7 / 8
In lipstick and mascara, polyethylene works as a structuring wax rather than as a particle, so replacing it is a wax-for-wax problem. A natural wax sold as ABWAX Revowax matched polyethylene on thermal behaviour and on penetration curves closely enough that the finished microplastic-free stick performed comparably. The paper also shows where the work actually sat: compatibility with the oils and the colours had to be mapped before the wax could be trusted in a real formula.
Market
Demand is being measured in intention, not money
8 / 8
The field's consumer research surveys 375 Indian shoppers and finds moral values, working through self-efficacy and attitude, as the strongest driver of intent to buy microplastic-free personal care. That is a market where this restriction does not bind, and it measures stated intent rather than the price anyone will pay. The buyer-side surveying measures satisfaction with the available ingredients, not budget.
No compliant shell has yet been shown to work at scale outside laundry and crop protection
A review published on 22 October surveys what has to replace polyurea, polyurethane, polyacrylate and melamine-formaldehyde capsule shells, and concludes that alternatives exist on paper while scalability, manufacturing simplicity and validated environmental fate stay open. The functions at stake are concrete: mechanical strength, barrier properties and controlled release are what the crosslinked shells deliver well, and their heavy crosslinking is what makes them persist. The authors place personal care alongside agrochemicals and detergents as the sectors the EU restriction hits hardest.
Signals to watch
US rules are moving toward reviewing the substitute itself
The patchwork assessment published on 16 October describes a market where federal agencies talk about drinking-water contamination while states legislate, with producer-responsibility laws live in seven states and several of them contested in court. California added microplastics to its Candidate Chemicals List on 1 October, which opens the state's Safer Consumer Products process. The listing alone imposes nothing on a formula.
Signals to watch
A new US centre is building the screening tools the substitutes will need
NYU Tandon and NYU Grossman launched the NYC Center for Healthier Plastic Solutions on 4 October, described at launch as the first US centre devoted to the health and environmental threats of plastics and to designing safer materials. It pairs engineers with medical researchers and uses automation and machine learning to test hundreds of formulations under wear, chemical exposure and heat.
