2. Negative hyperconjugation in silicon - Wikipedia

   en.wikipedia.org/wiki/Negative_hyperconjugation...

   The silicon effect also manifests in certain compound properties. Trimethylsilylmethylamine (Me 3 SiCH 2 NH 2) is a stronger base (conjugate pK a 10.96) than neopentylamine (conjugate pK a 10.21); trimethylsilylacetic acid (pKa 5.22) is a poorer acid than trimethylacetic acid (pKa 5.00). [1]

3. Negative hyperconjugation - Wikipedia

   en.wikipedia.org/wiki/Negative_hyperconjugation

   Negative hyperconjugation is seldom observed, though it can be most commonly observed when the σ *-orbital is located on certain C–F or C–O bonds. [ 3 ] [ 4 ] In negative hyperconjugation, the electron density flows in the opposite direction (from a π- or p-orbital to an empty σ * -orbital) than it does in the more common ...

4. Polydimethylsiloxane - Wikipedia

   en.wikipedia.org/wiki/Polydimethylsiloxane

   PDMS is also used as a component in silicone grease and other silicone based lubricants, as well as in defoaming agents, mold release agents, damping fluids, heat transfer fluids, polishes, cosmetics, hair conditioners, shining latex, and other applications. It can be used as a sorbent for the analysis of headspace (dissolved gas analysis) of ...

5. Silicone oil - Wikipedia

   en.wikipedia.org/wiki/Silicone_oil

   A silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane . These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties.

6. Hyperconjugation - Wikipedia

   en.wikipedia.org/wiki/Hyperconjugation

   Hyperconjugation can be used to rationalize a variety of chemical phenomena, including the anomeric effect, the gauche effect, the rotational barrier of ethane, the beta-silicon effect, the vibrational frequency of exocyclic carbonyl groups, and the relative stability of substituted carbocations and substituted carbon centred radicals, and the thermodynamic Zaitsev's rule for alkene stability.

7. Should We Be Using Batana Oil for Hair Growth?

   Meet batana oil, a fatty acid that’s known to nourish and repair dry, damaged hair. It’s also purported to help with hair growth and the reversal of grays, but we had to ask a few experts if ...

8. Electrophilic substitution of unsaturated silanes - Wikipedia

   en.wikipedia.org/wiki/Electrophilic_substitution...

   Conjugate addition reactions of allylsilanes are possible, although unsaturated aldehydes undergo only 1,2 addition. [15] The combination of an allylsilane with an α,β-unsaturated ketone in the presence of a Lewis acid is known as the Sakurai reaction. The enolate intermediate that results from addition can be functionalized with a separate ...

9. Hair oil - Wikipedia

   en.wikipedia.org/wiki/Hair_oil

   Coconut oil has properties that reduce protein loss in hair when used before and after wash. [9] Coconut oil is known to have lauric acid , which is a type of fatty acid that may penetrate the hair shaft due to a low molecular weight and linear conformation.
