High Quality Hydroxypropyl-beta-cyclodextrin CAS 94035-02-6 for UV-Protection Textiles

 Hydroxypropyl-beta-Cyclodextrin in UV-Protective Textiles: Applications, Mechanisms and Functional Finishing Technologies

1. Introduction: The Growing Demand for UV-Protective Textiles

With increasing awareness of ultraviolet (UV) radiation protection, the demand for functional textiles is expanding across sportswear, outdoor clothing, protective garments and everyday apparel.

Traditional textile materials provide different levels of natural UV protection depending on fiber composition, fabric structure, thickness and other physical properties. However, advanced textile finishing technologies offer additional possibilities for improving fabric UV resistance.

Hydroxypropyl-beta-Cyclodextrin (HP-β-CD), CAS No. 94035-02-6, is an important cyclodextrin derivative attracting research interest in functional textile applications.

Due to its distinctive molecular inclusion properties, HP-β-CD can encapsulate selected functional compounds, including UV-absorbing agents and natural active ingredients. This provides a potential approach for developing functional textile finishing systems designed to enhance UV protection and improve the retention of active components.

2. What Is Hydroxypropyl-beta-Cyclodextrin (HP-β-CD)?

Hydroxypropyl-beta-Cyclodextrin is a chemically modified derivative of beta-cyclodextrin.

Its molecular structure consists of a hydrophilic exterior and a relatively hydrophobic internal cavity. This unique structure allows HP-β-CD to form inclusion complexes with suitable guest molecules through molecular recognition and non-covalent interactions.

Key functional characteristics include:

• Molecular Inclusion Capability: Can encapsulate suitable hydrophobic or relatively poorly water-soluble compounds.
• Improved Solubility: Hydroxypropyl modification improves the aqueous solubility of beta-cyclodextrin.
• Guest Molecule Stabilization: Inclusion complex formation may help protect certain active compounds from environmental degradation.
• Controlled Release Potential: Suitable inclusion systems may influence the release behavior of encapsulated substances.

These characteristics make HP-β-CD an interesting functional ingredient for applications in pharmaceuticals, cosmetics, food technology and advanced textile finishing.

3. How Does HP-β-CD Work in UV-Protective Clothing?

One of the promising applications of HP-β-CD is its use in developing functional textile finishing systems.

Its contribution to UV-protective textiles mainly involves two technical mechanisms.

3.1 Encapsulation of UV-Absorbing Agents

Certain UV absorbers, such as benzotriazole derivatives, can be incorporated into HP-β-CD inclusion systems.

The cyclodextrin cavity can accommodate suitable guest molecules, potentially improving their dispersion, stability and compatibility within a finishing formulation.

When applied to textile materials through appropriate finishing technologies, these functional components can contribute to the UV-protective performance of the treated fabric.

Natural active ingredients, including tea polyphenols, have also been investigated in HP-β-CD-based textile finishing systems.

3.2 Fixation on Textile Fiber Surfaces

Encapsulation alone is not sufficient to ensure long-term textile performance.

The fixation of HP-β-CD and its inclusion complexes onto fiber surfaces is another important consideration.

Different approaches, including in-situ deposition, hydrogen-bond interactions and suitable chemical fixation technologies, can be explored to improve the attachment of functional components to textile fibers.

Effective fixation is particularly important for maintaining UV-protective performance during repeated washing and daily use.

4. Research Progress: HP-β-CD for UV-Protective Textile Finishing

Recent research has demonstrated promising possibilities for applying HP-β-CD in functional textile development.

Case 1: UV-Resistant Silk Fabrics

A 2022 study published in the Journal of Applied Polymer Science investigated the functionalization of silk fabrics using boronic-acid-functionalized HP-β-CD-coated Fe₃O₄ particles.

Through an in-situ deposition process, the modified particles were deposited onto silk fiber surfaces.

The treated silk fabrics demonstrated significantly improved ultraviolet protection factor (UPF) performance compared with untreated fabrics.

Case 2: HP-β-CD/Tea Polyphenol-Treated Polyester Fabrics

A 2024 study investigated the application of HP-β-CD inclusion complexes containing tea polyphenols to polyester fabrics.

The treated fabrics showed substantially improved UPF performance. Their UV-protective, antibacterial and antioxidant properties were significantly retained after 20 washing cycles.

This research highlights the potential of HP-β-CD-based functional finishing technologies for sportswear and outdoor textile applications.

Case 3: UV-Resistant Wool Fabrics

Another 2024 study published in the Arabian Journal of Chemistry investigated wool fabrics treated with HP-β-CD-coated Fe₃O₄ nanoparticles.

Using lipoic acid as part of the fixation approach, the modified wool fabrics demonstrated improved UV resistance, together with additional wrinkle-resistance and antibacterial properties.

These studies provide useful technical evidence for exploring HP-β-CD in the development of multifunctional textile materials.

5. Key Application Areas of HP-β-CD in Functional Textiles

Based on these research directions, HP-β-CD has potential applications in several textile product categories.

Application	Potential Functional Benefits
UV-Protective Clothing	Supports the development of UV-resistant fabric finishing systems
Sportswear	Helps incorporate functional UV-absorbing ingredients into textile treatments
Outdoor Apparel	Supports the development of functional fabrics for outdoor use
Polyester Fabrics	Provides possibilities for inclusion-complex-based functional finishing
Silk and Wool Textiles	Can be explored in advanced surface functionalization technologies

For textile manufacturers, HP-β-CD offers an interesting platform for developing functional finishing formulations rather than acting as a standalone UV-filtering agent.

6. Why Is Wash Durability Important in UV-Protective Textiles?

For commercial UV-protective clothing, initial UV protection performance is only one part of product development.

Repeated washing may remove or reduce the concentration of functional finishing agents on textile surfaces, potentially affecting the fabric’s UV-protective properties.

Therefore, the fixation method, compatibility between finishing agents and textile fibers, and resistance to repeated washing are important factors in evaluating functional textile performance.

Research involving HP-β-CD/tea polyphenol-treated polyester fabrics has demonstrated the retention of functional properties after 20 washing cycles.

However, actual wash durability and UPF performance depend on the complete formulation, application process, textile substrate and testing conditions.

Finished fabrics should be evaluated using appropriate standardized UPF testing methods to determine their actual UV-protective performance.

China Chemical Factory High Quality Best Price Oxytocin CAS 50-56-6 with good service Wholesale & Bulk

 Oxytocin is absorbed by the oral mucosa and selectively acts on the smooth muscles of the uterus, promoting uterine contractions. It is suitable for hastening parturition.

 

Oxytocin is a kind of uterotonic drug, has a selective excitatory effect on uterine smooth muscle, strengthens its contractions, the labor uterus is most sensitive to oxytocin (increased estrogen secretion), the immature uterus is unresponsive to this product, the uterus is less responsive to oxytocin in the first or second trimester, and gradually increases in the third trimester of pregnancy, reaching the highest before delivery. Small doses can strengthen the rhythmic contraction of smooth muscle at the bottom of the uterus, strengthen its contractility, accelerate the frequency of contraction, and the contraction nature is similar to natural childbirth, and maintain polarity and symmetry, so it is clinically used to induce labor and induce labor. Large doses make the uterine muscle tonic contraction, clinically used to compress the blood vessels between muscle fibers, prevent postpartum hemorrhage and postpartum insufficiency, and promote lactation, so that the breast ducts contract, promote milk discharge from the breast, but can not increase the secretion of milk, can only promote milk excretion.

Parameters of Oxytocin CAS 50-56-6

 

Uses:

 

Oxytocin is a cyclic nonapeptide hormone — Cys–Tyr–Ile–Gln–Asn–Cys–Pro–Leu–Gly–NH₂ with a disulfide bridge between Cys¹ and Cys⁶. It is synthesized in the hypothalamus (paraventricular and supraoptic nuclei), stored in the posterior pituitary, and released into circulation. It was first synthesized by Vincent du Vigneaud in 1953 (Nobel Prize, 1955).

 

Key identifiers & properties

 

Potency is expressed in International Units (IU) rather than mass alone: pharmacopeial grade is typically ≥480 IU/mg (USP/EP). This matters because "1 mg" ≠ a fixed number of units unless potency is stated.

 

Main uses

 

1. Approved clinical uses (prescription drug only, hospital setting)

 

Induction/augmentation of labor — IV infusion titrated from very low dose (e.g., 1–2 mU/min) up to a defined maximum under continuous CTG monitoring.

 

Prevention and treatment of postpartum hemorrhage — IM or IV after delivery of the baby/placenta; on the WHO Model List of Essential Medicines and included in WHO's PPH recommendations.

 

Management of incomplete/missed miscarriage — often combined with misoprostol or mifepristone.

 

Oxytocin challenge test (OCT/CST) — assessment of placental reserve/fetal tolerance.

 

Nasal spray/drops — to assist milk ejection (let-down) in postpartum women with lactation difficulty.

 

2. Veterinary medicine

 

Dystocia assistance, expulsion of retained placenta, induction of parturition, milk let-down in dairy animals, uterine involution support. Widely used in cattle, swine, sheep, and small-animal practice.

 

3. Research (RUO-grade peptide)

Selling points (why buyers choose it)

 

A. If you are marketing/sourcing API or finished drug

 

Essential-medicine status — WHO EML listing + inclusion in national essential-medicine lists → steady, policy-backed demand in maternal-health programs and public tenders.

 

Huge, recurring market — PPH is a leading cause of maternal mortality globally; oxytocin is first-line prophylaxis and treatment, so demand is volume-driven and non-discretionary.

 

Low cost, high volume — mature synthetic process (solid-phase peptide synthesis) keeps COGS low; margins come from GMP compliance, registration dossiers, and cold-chain reliability rather than molecule scarcity.

 

Off-patent generic — no IP barrier; competition is on quality documentation (DMF/CEP, GMP, WHO PQ, USP/EP/BP/ChP monograph compliance), stability data, and supply continuity.

 

Broad dosage-form flexibility — injectable ampoules/vials, lyophilized powder for injection, nasal spray/drops, and combination packs for active management of the third stage of labor (AMTSL).

 

Multi-species applicability — one API serves human pharma and veterinary markets, expanding customer base.

 

Differentiators that actually win tenders: verified potency (IU/mg), low vasopressin/impurity profile, single impurity identification, endotoxin/bioburden control, 24-month shelf life with real-time stability, cold-chain/temperature-monitoring logistics, and reliable batch-to-batch consistency.

 

B. If you are selling research-grade peptide

 

High purity (≥95–98% by HPLC) with MS confirmation and full COA/HPLC-MS/NMR spectra provided.

 

Correct disulfide cyclization confirmed (critical — misfolded linear analog is inactive).

 

Lyophilized, additive-free, TFA-salt or acetate-salt options; custom salt/form available.

 

Custom services: analogs (e.g., carbetocin, desmopressin-family variants), labeled forms (biotin, FITC, fluorescent), scrapable quantities from mg to g.

 

Fast dispatch, small-pack options (1/5/10 mg), dry-ice/cold shipping, and responsive tech support with literature citations.

 

Clear RUO labeling and compliance documentation (SDS, non-human-use statement).

 

C. Cross-cutting commercial strengths

 

Long history of clinical use with well-characterized safety/pharmacology → low perceived technical risk for formulators.

 

Stable, predictable demand unaffected by fashion/trends (maternal health is a permanent public-health priority).

 

Amenable to both synthetic and (historically) extraction routes; supply not dependent on rare raw materials.

 

Important caveats to state honestly

 

It is a prescription-only, high-risk medicine. Contraindications include cephalopelvic disproportion, obstructed labor, abnormal fetal position, placenta previa, cord prolapse, fetal distress, previous cesarean/uterine surgery, hyperstimulation, severe pre-eclampsia, and multiparity risks. Overdose can cause uterine rupture, fetal hypoxia/death, water intoxication/hyponatremia, and hypertensive crisis. It must be used only under medical supervision with monitoring.

 

Not a cosmetic or wellness ingredient. Claims about "love hormone" sprays, relationship enhancement, bodybuilding, or autism self-treatment are unsupported for consumer products; many jurisdictions prohibit such use. Research-grade material must be labeled not for human/animal consumption.

 

Fragile molecule. Potency loss from heat, light, moisture, adsorption to containers, and improper reconstitution is the #1 cause of customer complaints — storage/handling instructions should be prominent in any product listing.

 

Regulatory gate: human use requires national marketing authorization/GMP API; export may require import permits. Selling points should emphasize compliance documents rather than unapproved therapeutic claims.
