The present invention relates to a process for selectively producing a cellulose ether derivative with a very high reaction efficiency of an organohalide compound. There is provided a process for producing a cellulose ether derivative such as carboxymethyl cellulose and hydroxyethyl cellulose in which a low-crystalline powdery cellulose having a crystallinity of 50% or less is reacted with an organohalide compound such as ethylene chlorohydrin, a monohaloacetic acid and a salt of the monohaloacetic acid in the presence of a base.

Method for producing cellulose ether derivative

The invention provides a means capable of effectively inactivating and removing allergen or a precursor thereof. The invention relates to an allergen-reducing agent containing water and a water-soluble polymer compound having units having hydroxy or carboxy groups wherein at least a part of hydrogen atoms of the hydroxy or carboxy groups are substituted by specific groups containing a polyether group.

Allergen depressant and depression method

A process for the preparation of an o/w emulsion, which comprises mixing together a high molecular compound carrying at least on side chains thereof groups represented by the following formula (1):&#x2014;(OX)-E-R&#x2003;&#x2003;(1)wherein n 'X's may be the same or different and each independently represents a linear or branched, divalent, saturated Chydrocarbon group, n stands for a number of from 5 to 300, Erepresents an ether bond or an oxycarbonyl group (&#x2014;OCO&#x2014; or &#x2014;COO&#x2014;), and R represents a linear or branched, Calkyl group which may be substituted by hydroxyl group(s), an aqueous solution of a water-soluble polyol, and a hydrophobic compound, and diluting a resulting mixture with water, and the o/w emulsion obtained by the preparation process. The emulsion according to the present invention is excellent in touch feeling to the skin and is good in stability.

Oil-in-water emulsions and process for producing the same

The invention relates to an oil-in-water emulsion obtained by mixing (a) a polymer compound having, in a side chain, a group represented by formula ():-OX)-E-R&#x2003;&#x2003;(1)wherein X represents a C1 to C6 divalent saturated hydrocarbon group, n is a number of 5 to 300, Eis an ether linkage or an ester linkage, and R represents a C4 to C30 hydrocarbon group, (b) a water-soluble polyol, (c) a nonionic surfactant, (d) a hydrophobic compound, and water and diluting the resulting mixture with water and a process for producing the same.

Oil-in-water emulsion and process for producing the same

A gelling agent having a high ability of gelling an oily base which is capable of giving a gel composition having a strong gel strength and a good transparency, a gel composition having a strong gel strength and a good transparency, an external composition having a good feel upon use, a cosmetic preparation having a good feel upon use, and a fragrance composition having a good transparency and a good appearance is provided. An amide compound represented by the following formula 1: is used. In formula 1, R, Rand Rare each independently a hydrogen atom or an alkyl group having a carbon number of from 1 to 3 with the proviso that at least one of R, Rand Ris a hydrogen atom. R, Rand Rare each independently a saturated or unsaturated, linear or branched hydrocarbon group having a total carbon number of from 6 to 24 which optionally has at least one group selected from the group consisting of an ether group, amide group, ester group, amino group and hydroxyl group; and m, n and p are each independently an integer of from 0 to 3.

Polyvalent metal salts of phosphoric diester and organo(poly)siloxanes

Phosphoric esters (mono-, di- or triester) is useful as, for example, a cleaner, an emulsifier, an antistatic agent, metal-chelating agent and a lubricant for fibers. It is produced at a high yield while completely trapping the hydrogen chloride gas formed as a by-product. The reaction between a phosphorus oxyhalide and an organic hydroxyl compound to produce a phosphoric ester is effected in the presence of a metal salt of an acid having a pKa of from -5 to 13.
