Abstract: Skin cosmetics which are excellent in moistness and persistency of moisture-keeping effect, show light sense of touch when used and have excellent periodical stability. In addition, there are provided skin cosmetics which do not cause stickiness after their use, are excellent in rough skin improving and preventing effects, wrinkle preventing and improving effects, dinginess improving effect and the like, and also have an effect in providing the skin with smoothness and liveliness. Also, in the case of skin cleansing compositions, they exert such effects that they can provide the skin with liveliness and moistness after washing and can effectively remove fishy and ammonia smells or the like filthy smell adhered to the hand, the skin and the like. A skin cosmetic characterized in that it contains (A) at least one substance selected from seed extracts and seed hull extracts of a plant belonging to the genus Carya of the family Juglandaceae in an amount of from 0.

Abstract: This invention relates to a novel lipid composition for use in cosmetics capable of increasing moisture-keeping ability or barrier function of the stratum corneum, protecting the skin and improving dry or rough skin, and to products which use the same, such as cosmetics and medicaments. Particularly, it relates to a lipid composition which comprises at least one component (A) selected from the group consisting of a 2-acylaminoalkane-1,3-diol and optically active compounds thereof, at least one component (B) selected from the group consisting of a 2-acylaminoalkane-1,3-diol in which at least one of the &agr;-position and &bgr;-position of the acyl group is substituted with hydroxyl group and optically active compounds thereof and at least one component (C) selected from sterols, wherein the components (A), (B) and (C) are mixed at a ratio that constructs a liquid crystal structure, and to products which contain the lipid composition, such as cosmetics and medicaments.

Abstract: A composition comprising a 2-acetaminoalkane-1,3-diol or its optical isomer having the formula: ##STR1## wherein R.sub.1 represents a linear alkyl group having 9 to 17 carbon atoms; a 2-acylaminoalkane-1,3-diol or its optical isomer having the formula: ##STR2## wherein R.sub.1 has the same meaning as given above for formula (I) and R.sub.2 represents a substituted or unsubstituted linear acyl group having 14 to 24 carbon atoms; and a compound having a sterol group. This composition forms a lamellar liquid crystal phase and can retain moisture when applied to the skin.

Abstract: A process for producing Coenzyme Q.sub.10 which comprises cultivating a microorganism belonging to genus Cryptococcus, Rhodotorula, Sporobolomyces, Torulopsis, Sporidiobolus, Oosporidium, Aspergillus, and Cladosporium in a culture medium to which isopentenyl alcohol is added and recovering the thus formed Coenzyme Q.sub.10.

Abstract: A process for producing Coenzyme Q which comprises cultivating a microorganism belonging to genus Pseudomonas in a culture medium to which at least one member selected from the group consisting of isopentenyl alcohol (3-methyl-3-butene-1-ol), dimethyl allyl alcohol (3-methyl-2-butene-1-ol), geraniol, isopentenyl acetate, dimethyl allyl acetate, geranyl acetate and .beta.-methyl crotonic acid is added, and obtaining thus formed Coenzyme Q.
