Prevention of aerosol hair conditioner valve clogging: Prevention of aerosol hair conditioner valve clogging. (Sunstar, Inc., Japan). Jpn. Tokkyo Koho JP 59051348 B4 13 Dec 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: ICM: B05B009-04. ICA: B65D083-14; C09K003-30. APPLICATION: JP 79-144824 7 Nov 1979. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Aerosol hair conditioners contain Me vinyl ether-monobutyl maleate copolymer (I) [25119-68-0] and the container valve stem is made of polyacetals. The combination of I and polyacetals prevents clogging. One aerosol contained: I 4.0, 2-amino-2-methyl-1-propanol 0.15, perfume 0.2, EtOH (99%) 35.65, and propellant [Freon 12 and Freon 11 (3:2)] 60.0% by wt. The stem of the aerosol was made of polyacetal. Expts. showed that no clogging was obsd. after the aerosol was used 30 times.
