An industrially advantageous process for producing 4-homoisotwistane-3-carboxylic acid. According to the invention, tricyclo[5.2.1.0.sup.2,6 ]dec-8-yl-methylformate (II) is contacted with an inorganic strongly acidic catalyst to obtain 4-homoisotwistane-3-carboxylic acid (I). ##STR1##

A fiber processability-improving agent comprising a salt of (meth-)acrylic acid and/or maleic acid (co-)polymer is provided. This agent has an average molecular weight of up to 10,000 and is useful for improving dyeability and scouring properties of fibers to realize a level dyeing and an excellent hand.

A pearlescent liquid suspension comprises essentially (A) a cationic surface active agent, (B) a higher alcohol, and (C) an alpha-mono(methyl-branched alkyl) glyceryl ether. The total amount of these ingredients should be from 1 to 40 wt %, mixing ratios of (A), (B) and (C) lying within an area surrounded by lines connecting the specified points a, b and c on the triangular coordinate of the ternary system. The suspension according to the invention is more inexpensive than known pearling agents....

A dispersion for the water-in-oil suspension polymerization is stabilized by a stabilizer comprising a polymer having 70 to 99 mole percent of a lipophilic, ethylenically unsaturated monomer units and 1 to 30 mole percent of ethylenically unsaturated monomer units having a cationic group.

A composition of cleansing and wiping skin in the circumanal region which comprises at least one oil selected from the group consisting of vegetable oils, animal oils and synthetic oils, and a silicone oil and has a viscosity of not more than 30 cs as measured at 5.degree.0 C. The composition according to the invention is preferably used after excrement is wiped off with usual toilet paper and facilitates removal of excrement residues on the skin of circumanal region. Besides, when the compositi...

An industrially advantageous process of preparing phosphoric acid diesters of high purity. To a mixture of phosphoric esters comprising phosphoric monoesters and phosphoric diesters, a base is added in an amount of 0.5-1.3 equivalents based on phosphorus atoms which are contained in the mixture. The phosphoric monoesters are converted into orthophosphoric acid and organic hydroxyl compounds by hydrolysis, after which step the orthophosphoric acid and organic hydroxyl compounds are removed from t...

In a shampoo composition which comprises an anionic surface active agent and/or an amphoteric surface active agent as a base, the following two ingredients (A) and (B) are further comprised: (A) 0.5 to 10 wt % of an N-acyl-N-methyl-beta-alanine or its salt represented by the formula (I) ##STR1## in which R represents a linear or branched, saturated or unsaturated hydrocarbon group having from 7 to 21 carbon atoms, and M represents hydrogen, alkali metal etc., (B) 0.5 to 20 wt % of one or more of...

A chalcone derivative of the formula (I): ##STR1## in which R.sub.1 represents hydrogen or a methyl group, and R.sub.2 represents a linear or branched aliphatic hydrocarbon group having from 2 to 24 carbon atoms. The derivative is effective in protecting the skin when made into ultraviolet absorbing agents including an anti-sunburn oil, since it has the maximum absorbing capacity at a wave length in the vicinity of 350 nm, does not irritate the skin and is highly compatible with a cosmetic base.
