Solutions that are more than skin deep

北京快三开奖结果彩票控 www.8hib.cn Our solutions are more than skin deep.  Through transdermal and topical  applications, skin can be an effective way to deliver some medications.   Regardless of whether the drug is being delivered via gel, lotion, cream, ointment or foam, features including texture, adhesion,  and spreadability, as well as feel and smell, are important attributes to  consider for optimal patient compliance. For topical and transdermal application, Ashland's pharmacuetical team works with the talented skin care team to find alluring and luxurious ways to effectively and efficiently formulate topical and transdermal applications.

Topical treatments are administered to skin or mucous membranes to alleviate a variety of conditions. These treatments broadly encompass creams, foams, gels, lotions and ointments. There are a number of sought-after attributes for conferring desired properties to a topical formulation: rheology control, spreadability, adhesion and diffusion control. Ashland offers high-quality cellulose ethers such as Natrosol™ 250 hydroxyethylcellulose, Klucel™ hydroxypropylcellulose and Aqualon™ sodium carboxymethylcellulose to deliver these properties. Some of the topical film formers offered in our skin-care product lines are also suitable for use in topical applications. Plasdone™ povidone is also a good film former for topical applications.

The molecular structure of cyclodextrins creates a bucket-like cavity that can function to complex with molecules or functional groups on molecules. The substitution of hydroxyl groups on native cyclodextrins to make hydroxypropyl-?- or hydroxypropyl-γ-cyclodextrins (HPBCD or HBGCD) significantly enhances their solubility and makes them more suitable for drug solubilization. This mechanism makes the Cavitron and CAVASOL HPBCDs and HPGCDs capable ...

Ashland's Ferronyl™ iron supplement is a carbonyl iron powder that is an effective answer to iron deficiency treatment and prevention because it has a much higher iron level than ferrous salts, such as ferrous gluconate, ferrous sulfate or ferrous fumarate. Ferronyl iron supplement also has a fine, narrow particle size range (7-9 μm) that increases its bioavailability. The regulatory compliance information for all Ashland products varies...

Klucel™ hydroxypropylcellulose (HPC) is a nonionic water-soluble cellulose ether with a remarkable combination of properties. It combines organic solvent solubility, thermoplasticity and surface activity with the aqueous thickening and stabilizing properties characteristic of other water-soluble cellulose polymers available from Ashland. Klucel HPC films are flexible without plasticizers and non-tacky at high humidity.

Natrosol™ hydroxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. It is made by reacting ethylene oxide with alkali-cellulose under rigidly controlled conditions. Purified HEC for personal care and cosmetic applications is typically sold at 95.0 percent minimum purity (dry basis).  Solutions of Natrosol HEC are pseudoplastic or shear-thinning. As a result, personal care products formula...
