1. A personal care composition, comprising:
a cosmetically acceptable carrier;
a silicon glycan of formula (I):

OG Complex Work Unit Chemistry
wherein each A comprises an independently selected saccharide moiety; wherein each W is an independently selected beta-amino alcohol moiety; wherein each Y comprises an independently selected organosilicon moiety; wherein each R is independently selected from the group consisting of substituted or unsubstituted hydrocarbyl groups, ether moieties, amine moieties, and H; wherein each R1 is independently selected from the group consisting of substituted or unsubstituted hydrocarbyl groups and H; wherein each Z is an independently selected ether moiety; wherein each subscript o is independently 0 or 1; wherein subscripts x and y are each independently from ≥0 to <1; wherein subscript z is selected from >0 to 1; with the proviso that x+y+z=1; wherein moieties indicated by subscripts x, y, and z may be in randomized or block form in the silicon glycan; wherein (i) each saccharide moiety A is a hexose; (ii) each R1 is H or a C1-4 hydrocarbyl group; (iii) subscript o is 1 in each moiety indicated by subscript y; (iv) subscript o is 1 in each moiety indicated by subscript z; (v) in each moiety where subscript o is 1 the ether moiety Z comprises an ether of formula —(CtH2fO)u—, where subscript t is independently 2 to 4 in each moiety indicated by subscript u and subscript u is 1 to 50; (v) each R is H, a C1-18 hydrocarbyl group, a polyoxyalkylene group, or a tertiary amino group; or (vi) any combination of (i) to (v); and wherein each saccharide moiety A is a component of and collectively form a hydroxyethyl cellulose; and
at least one personal care active selected from the group consisting of an absorbent; an acid; an aesthetic modifier; an antiaging agent; an antidandruff agent; an antifrizz agent; an antimicrobial agent/preservative; an antioxidant; an antiperspirant or deodorant active; an antistatic agent; a bioactive agent; a bleaching or coloration agent; a chelating agent; a cleansing surfactant; a conditioning agent; a colorant; a consistency factor; a deodorant; an emulsifying agent; an emollient; a fat; a filler; a foaming agent; a fragrance; a hair oil; a hair treatment active; a hair waving/straightening agent; a hair styling agent; a hard particle; a humectant; a lecithin; a light management powder or particle; a lubricating agent; a moisturizer; a natural ingredient; an oil; an opacifier; a pearlizing agent; a penetrant; a pH adjusting agent; a phospholipid; a pigment; a plant extract; a polymer; a preservative; a protein/amino acid; a rheology modifier; a salt; a sensory modifier; a silicone oil; a skin care active; a skin coolant; a skin protectant; a slip agent; a soap; a soft particle; a stabilizer; a sun care active; a sunscreen additive; a surfactant; a thickener; a vitamin; a water proofing agent and a wax; and
wherein the personal care composition is a hair styling formulation.
