comprising at least two quaternary ammonium groups” (Spec. 13: 8-13)
required by instant claim 1.
5. Niemiec’s component c) “is a detergent. By ‘detergent,’ it is meant
any known surfactant and/or soap that is compatible with the silicone agents
and the cationic agents of the cleansing composition, and may . . . include
anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric
surfactants . . . and mixtures thereof” (Niemiec, col. 6, ll. 43-50).
6. Niemiec includes long chain alkyl glucosides as examples of suitable
nonionic surfactants (Niemiec, col. 7, ll. 9-11), but does not describe the
“sugar chosen from C3 to C5 monosaccharides substituted with at least one
C1 to C22 carbon chain” required by instant claim 1.
Bertho
7. Bertho describes “mixtures of alkyl pentosides [which] make
remarkable non-ionic surface active agents” (Bertho, col. 6, ll. 14-15).
8. Bertho teaches that alkyl pentosides surfactants “may be added to hair
care products” because of “their ability to lower the surface tension . . . of
water and their foaming, emulsifying and detergent power” (Bertho, col. 6,
ll. 21-35).
9. Bertho teaches that alkyl pentoside surfactants are economical to
produce (Bertho, col. 1, l. 45 to col. 2, l. 32), and “fully biodegradable . . .
whilst having a high level of stability” (id. at col. 7, 10-13).
10. Bertho teaches that alkyl pentosides can be used in shampoos which
also include “the usual additives” (Bertho, col. 17, ll. 44-48), such as
cationic conditioning agents like “cationic cellulose derivatives (POLYMER
JR400® . . .)” (id. at col. 18, ll. 32-40).
