I. Industry Positioning of Cholesterol and Its Derivatives
Cholesterol and its derivatives are core intermediates and raw materials in the pharmaceutical, nutrition and health, cosmetics, and fine chemical industries. They are widely used in applications such as vitamin D₃ synthesis, pharmaceutical excipients, high-end skincare formulations, and animal nutrition fortification. They are a key link between upstream raw materials and downstream end products.

II. Market Pain Points of Animal-Source Products and the Breakthrough of Plant-Source Products
For a long time, cholesterol products on the market have relied primarily on animal sources (animal brain, spinal cord, lanolin, etc.), but these products have significant drawbacks:
●Safety Risks: Raw materials are perishable and may carry contaminants such as endogenous viruses, pesticide/veterinary drug residues, and foreign proteins, threatening the safety of downstream applications (such as pharmaceutical-grade excipients and cosmetic raw materials).
●Quality Fluctuation: The complex composition of animal-sourced ingredients (unclear component ratios and the coexistence of harmful ingredients) leads to poor batch-to-batch consistency, making it difficult to meet the stringent standards of high-end industries. Plant-derived cholesterol and derivatives, with their core advantages of “zero animal virus risk, controllable ingredients, and batch stability,” have become key solutions to address these pain points and continue to expand their application in fields such as pharmaceuticals (injectable-grade excipients), cosmetics (sensitive skin formulas), and nutrition and health (high-purity raw materials).

III. Baoboluo’s Plant-derived Product Matrix
Leveraging plant extraction and synthesis technologies, the company has developed a comprehensive line of plant-derived cholesterol and derivatives, covering the entire chain from basic raw materials to functional derivatives:
● Core Raw Materials: Plant-derived Cholesterol, Plant-derived Cholesterol Acetate, 7-Dehydrocholesterol (Plant-derived)
● Hydroxylated Derivatives: 25-Hydroxycholesterol (Plant-derived), 25-Hydroxydehydrocholesterol (Plant-derived), 25-Hydroxy Vitamin D3
● Functionalized Compounds: Anhydrocalcifediol, Calcitriol

IV. Product Technology Analysis and Application Scenarios
1. Plant-derived Cholesterol (CAS No. 57-88-5)
● Characteristics: Purity ≥99%, free of animal-derived contaminants (viruses, foreign proteins), infrared spectrum consistent with animal-derived cholesterol, and chemical properties fully matching those of animal-derived cholesterol. ● Applications:
◎ Starting material for vitamin D₃ synthesis (core substrate for photochemical methods);
◎ High-end pharmaceutical excipients (liposome membrane materials, injectable emulsifiers);
◎ Cosmetic emulsifier (naturally derived, suitable for sensitive skin formulations).

2. Plant-derived cholesterol acetate (CAS No. 604-35-3)
● Features: Ester bond modification improves chemical stability, preventing the risk of free cholesterol oxidation; plant-derived process ensures ester bond purity.
● Applications:
◎ Pharmaceutical synthesis intermediate (esterified precursor for steroid hormone derivatives);
◎ Cosmetic liposome carrier (encapsulates active ingredients to enhance transdermal absorption).

3. 7-Dehydrocholesterol (plant-derived)
● Features: Plant-derived process avoids animal-derived impurities, resulting in a stable UV absorption peak and a 10%+ increase in photoconversion efficiency to vitamin D₃.
● Applications: Core precursor for the industrial production of vitamin D₃ (replacing animal-derived sources to reduce impurity interference in the end product).

4. 25-Hydroxy Derivatives (25-Hydroxycholesterol, 25-Hydroxydehydrocholesterol, Plant-Based)
● Features: These plant-derived raw materials are enzymatically or chemically hydroxylated, resulting in >99% purity at the hydroxyl sites, providing highly active substrates for calciferol-based drugs.
● Applications:
◎ Synthetic precursors for calcifediol (anhydrocalcifediol) and calcitriol;
◎ Research-grade tool molecules (for exploring calcium metabolism regulation mechanisms).

5. 25-Hydroxy Vitamin D3, Anhydrocalcifediol, and Calcitriol
● Features:
◎ 25-Hydroxy Vitamin D3: Directly connects to the synthesis of calcifediol, shortening the reaction process by three steps using plant-based precursors;
◎ Anhydrocalcifediol: Highly crystallinity, impurities ≤0.1%, meeting pharmaceutical-grade oral dosage forms;
◎ Calcitriol: An active vitamin D₃ derivative. Its plant-based synthesis ensures batch stability, making it suitable for precise nutritional formulations. ● Applications:
◎ Bone metabolic disease drugs (calcifediol/calcifetriol preparations);
◎ High-end nutritional supplements (precisely regulate calcium absorption);
◎ Anti-aging cosmetic ingredients (promote epidermal cell differentiation).

V. Baoboluo’s Technological Moat
As a professional manufacturer of plant-derived cholesterol and derivatives, the company has established comprehensive capabilities from “plant extraction → derivative synthesis → quality control”:
● Raw material side: Screening plant varieties with high cholesterol content, establishing a stable supply chain, and controlling purity from the source;
● Technology side: Mastering core processes such as phytosterol conversion and selective hydroxylation modification, with multiple patents supporting product iteration;
● Quality side: Equipped with testing equipment such as HPLC and GC-MS, implementing six plant-specific quality inspection standards (including absence of animal-derived contaminants and component homogeneity verification) to ensure product consistency across every batch.
The rise of plant-derived cholesterol and derivatives is not only a technological breakthrough, but also an inevitable choice for the industry’s pursuit of “safety, stability, and sustainability.” With a full range of plant-based products as its fulcrum, Baoboluo helps the fields of medicine, cosmetics, nutrition and health break through the limitations of animal-based products and unlock higher-value application scenarios.
