Sensory texturizing agents in cosmeceuticals: Navigating the skin-bioactive interface and recent advancements
AI summary Read the abstract
Those creamy, silky textures in your lotions and serums come from thickening ingredients — and many traditional ones are synthetic (some tied to microplastic concerns). This review rounds up existing research showing that plant-based and fermented alternatives (like modified cellulose and konjac plant extracts) can now match synthetic thickeners in feel and performance while being gentler on skin and more biodegradable. For consumers, this means the "clean beauty" products popping up on shelves aren't just a marketing trend — the science backing more natural formulations is genuinely catching up to conventional options.
The quest for perfect skin has long captivated humanity, blending art and science in elegant alchemy of cosmeceuticals products that promise not only beauty but tangible therapeutic transformation. Central to these products are texturizing agents or rheology modifiers that govern viscosity, thixotropy, spreadability, and sensory perception while ensuring emulsion stability and controlled release of actives. Traditionally, synthetic polymers like carbomers, acrylates copolymers, and silicones have dominated due to their unparalleled robustness, pH independent thickening, and viscoelastic properties in complex oil in water and water in oil systems. However, escalating regulatory scrutiny, microplastic concerns, and clean beauty movement have accelerated a transition toward natural and bio based alternatives, reflecting a broader shift from synthetic to sustainable paradigms in cosmeceutical design. Recent advances showcase polysaccharides, microbial exopolymers, and plant derived biopolymers achieving rheological profiles rivaling synthetics, often with superior skin compatibility, biodegradability, and ecofriendly life cycle impacts. Hybrid and bio engineered modifiers like modified cellulose (e.g. EcoFlexy) and fermented polymers (e.g. hyaluronic acid), modified konjac glucomannan (e.g. Inagel Green), exemplify this convergence, offering high performance thickening with natural origin and enhanced sensory attributes. Hence, this review combines the latest evidence on mechanisms, safety performance metrics highlighting opportunities in biotechnology driven texturizers to resolve the texture absurdity and propel cosmeceuticals toward high efficacy formulations.

Effect of Addition of Spheroidal Cellulose Powders on Physicochemical and Functional Properties of Cosmetic Emulsions
AI summary Read the abstract
The cosmetics industry has historically used tiny plastic microbeads as scrubbing and texturizing agents in face creams, but these are now widely banned due to environmental harm. This study evaluated spheroidal cellulose powders — derived from plant material — as a biodegradable replacement, finding that creams containing cellulose particles of two different sizes (2 and 7 µm) performed best, delivering good skin hydration, favorable texture, and high consumer sensory ratings. The results support cellulose-based particles as a viable and genuinely biodegradable substitute for synthetic microplastics in personal care products.
Eco-Designing Cosmetic Products while Preserving the Sensorial-Application Properties: An Instrumental Approach toward Sustainable Formulations
AI summary Read the abstract
Researchers explored eco-design approaches for reformulating cosmetic skin care products using natural and biodegradable ingredients. The study demonstrated that synthetic texturizers like nylon-12 and PMMA could be replaced with starch, maltodextrin, and silica while maintaining sensorial application properties, supporting the reduction of microplastic-generating ingredients in personal care products.
Tailoring starch particle morphology through enzymatic, precipitation and spray-drying techniques as sustainable microplastic alternatives in cosmetics
AI summary Read the abstract
Scientists found a way to reshape starch particles from corn, tapioca, and mung beans into smooth, silky microbeads that could replace the tiny plastic particles (microplastics) commonly used in cosmetics like exfoliants and powders. This matters because those plastic microbeads don't break down in the environment and can end up in waterways, soil, and even our bodies, this starch-based alternative offers a biodegradable option that still feels good on skin, without sacrificing product quality.
Sustainable and biodegradable polymeric foams: Processing–structure–property relationships, scalability, and circular design perspectives
AI summary Read the abstract
This review paper takes stock of new plant-based and biodegradable foam materials, like those made from cellulose and plant sugars, that could replace traditional petroleum-based foams used in packaging and insulation. These greener alternatives break down more easily instead of persisting in the environment as plastic waste and microplastics, though the research shows some, like bio-based polyurethane foams, are still hard to recycle due to their chemistry. While scientists have made real progress, especially with super-insulating cellulose foams, the paper notes that cost, scalability, and further innovation (including AI-assisted design) are still needed before these materials show up widely
