Effect of plasticizer dibutyl phthalate on the thermal
This paper aims to investigate the effects of plasticizer dibutyl phthalate (DBP) on the thermal decomposition of nitrocellulose (NC) by using a series of analytical apparatuses. In the present study, the detailed structures of pure NC (NC-P) and NC with DBP (NC-D) were revealed by scanning electron microscope. It was found that the fibers in NC-D are more closely aligned than those in NC-P
AQUACOAT ECD: CRITICAL FORMULATION ATTRIBUTES OF PLASTICIZER
and type of plasticizer in a coating formulation should be optimized as it plays a critical role in controlling film flexibility, permeability and, in turn, the drug release profile. Insufficient plasticizer can cause film cracking after drying. To avoid this, 20-25% of plasticizer content is recommended based on ethyl cellulose solid content
Guideline on the use of phthalates as excipients in human
Dibutyl phthalate (DBP) DBP was associated with an anti-androgenic effect in a human cell line as it inhibited the binding of dihydrotestosterone to the androgen receptor with an IC 50 of 74 M (Christen et al. 2010). DBP was devoid of oestrogenic activity in vitro (Lee et al. 2012).

can serve pellets coated with blends of ethyl cellulose and Eudragit L. Dibutyl sebacate used as plasticizer of this coating shows a higher affinity to ethyl cellulose than to Eudragit L (Lecomte et. al., 2004). 3. Free membranes A membrane can be in the form of a free film co ntaining the active ingredient, or it can form
- Does plasticizer dibutyl phthalate affect thermal decomposition of nitrocellulose?
- This paper aims to investigate the effects of plasticizer dibutyl phthalate (DBP) on the thermal decomposition of nitrocellulose (NC) by using a series of analytical apparatuses. In the present study, the detailed structures of pure NC (NC-P) and NC with DBP (NC-D) were revealed by scanning electron microscope.
- What is a plasticizer – dibutyl phthalate (DBP)?
- Provided by the Springer Nature SharedIt content-sharing initiative Plasticizers like dibutyl phthalate (DBP) are widely employed to achieve the progressive burning properties for oblate spherical propellants. A plasticizer
- Who bought dibutyl phthalate and glycerol?
- Dibutyl phthalate (DBP) was purchased from Yonghua Chemical Technology Co., Ltd. Glycerol was purchased from Sinopharm Chemical Reagent Co., Ltd. All the reagents mentioned were of analytical purity (AR), and deionized water was utilized in the test process without additional purification.
- How does plasticizer DBP affect the microscopic structure and thermal decomposition mechanism?
- The effects of DBP on the microscopic structure, kinetic characteristics, and thermal decomposition mechanism of NC were investigated using a range of apparatus. The main findings can be summarized as follows: 1. Plasticizer DBP makes NC fibers present an adhesion state. The distance between fibers in NC-D is much lower than that in NC-P.
- Is nitrocellulose compatible with DBP?
- In this work, the impact of nitrogen content and uniformity of nitrogen distribution of nitrocellulose on its physical compatibility with DBP was analyzed. DBP is more intermiscible and better compatible with nitrocellulose by decreasing both the nitrogen content and the nitrogen uniformity.
- Why is DBP more intermiscible than nitrocellulose?
- DBP is more intermiscible and better compatible with nitrocellulose by decreasing both the nitrogen content and the nitrogen uniformity. The deterring depth of oblate spherical propellants by DBP is thus increased by lowing the nitrogen distribution uniformity.
